Mafundi wapo...

Hybrid cars zipo na service costs ndogo kuliko conventional cars... Mfano na zenyewe zinatumia oil kwenye injini ila frequency ya kuchange engine oil si kubwa kama gari yakawaida kwakua Hybrid car injini huwaka mda mchache na kuzima... Tena ukiwa kwenye folen mfano na ac ipo on... Utaona injini inazimika baada kama dakika 4 utasikia inawaka kwa ajiri ya kuchaji battery then itaunguruma kama sekunde 20 itazimika but functions nyingine zote zitaendelea kufanya kazi kwakua kichafanya kazi ni umeme tu. Hapo hata oil aichoki haraka kama oil ya kwenye gari ambayo si hybrid..

Na kumbuka regular service ya gari ni oil changing pomoja na filter yake (oil ya hybrid car kama upo tz at least 5w-30 fully synthetic oil usiweke hizi oil za kawaida kama sae 40 au hizi wengi wamezoe ya 20w-50), airfilters changing (both engine and cabin-ile ya ac) na brake pads sasa kwa Hybrid hivi vyote vinachukua muda kubadirisha... Hasa brake unaweza kuta gari inafikisha hadi km 200,000 ujawah badiarisha brake pads kwakua brakea zake hazitumiki mara kwa mara(regenerative braking ndo ufanya kazi mara nyingi)

Vingine ni vya kawaida.. ishu kama plug, kubadiri betri ile ya volt12, kusafisha egr valves kama ikijaa carbon, shocks absorbers na buahing hizi zipo hapa bongo (kumbuka uzuri wq toyota vitu vingi vya gari zake vinakua standard ni kufanya kuweza kuingilia kwa baadhi ya vitu vya gar zake hasa huku kwenye suspension systems

And the other major components they are too reliable (vitu kama car computers, engines, hybrid batteries, both motors yaani MG1 na MG2 zito za patikana ingawa kwakua hizi ndo za tengeneza transmission system, ikitokea zimekufa wewe nunua gearbox mpya kama tunavofanya hizi gari za kawaida.

Na ikitokea issue ni battery ya Hybrid ndo imekufa kuna namna nyingi na cheap ya kurekebisha kama fundi anajua achofanya. Unless una replace battery pack nzima ambayo haichukui hata nusu saa kubirisha..

Zingatia maji yasiingie mahala battery inakaa... Unapokua na hybrid car jitahidi kujua location ya battery zote mbili ili ujui namna ya kuilinda na maji.. pia kuzingatia kusafisha filter ya hewa inayokaa kwenye hybrid battery (maana hii ndo chanzo kikuu cha kuharibika kwa hizi battery) hakikisha battery inapata hewa ya kutosha.. (hizi gari kuna ambazo zina battery ya lithium ion na nyingine ni nickel cadmium sasa kila battery ina advantagea na disadvantages zake ingawa zote zinatengeneza joto zinapokua zinafanya kazi kama vile betri za simu.. sasa zinahitaji hewa ya kutosha ili ziweze kufanya kazi na kudumu kwa muda mrefu... Na kwa namna toyota walivo design kila battery pack inayotengeza hybrid battery ina temperature sensor kwa ajili ya monitoring ya temperature for every individual battery pack.. hii inasaidia effective protection ya battery when subjected to high temperature beyond required range..na hii ndo utakuta kuna fan ambayo inakaa kwenye kiti cha abiria kwa chini (kwa Toyota Prius) ambapo rotation speed yake inabadirika kulingana na temperature level ya battery. (Kwa watu wa dsm kama una gari Hybrid tumia AC as much as possible unapotumia hii gari hii itasaidia feni ya battery ku suck in cool air ambayo itakwenda kupoza battery..

Pia hii gari ni rahisi kufanya diagnosis kwa kutumia diagnostic machines kwakua zinakutajia specific problem na hata kama nu battery unaweza zoom in kwakila battery pack individual na ukajua ni pack gan ubadirishe na kufanya charging balancing ili battery zote ziwe even kwenye charging na discharging.

Zingatia tu kua kwenye mfumo wa uzungushaji maji ya kupozea injini kuna ambazo zinakuja na electric water pump na kuna zinazokuja na non electric water pump-ambayo inazungushwa na timing chain..so kwa zinazokuja na electric water pump when check engine light is on haraka saana weka gari pembeni chunguza chanzo cha hiyo check engine light..kwakua kwa hii gari yenye electric water pump the only way kujua kua ni water pump ndio imekufa is through check engine light illumination.

Kitu kingine cha kujua hii gari unapata a very good gas mileage kwenye trip za mjini kwakua muda mwing regenerative braking system inafanya kazi(zile stop and go zinafanya regenerative braking ina jaza chaji battery wakati wa kusimamisha gari but for high driving kwa speed 90+ gas mileage inashuka kidogo kwakua muda mwingi injini inawaka ku keep up with driving needs za dereva..so hapa both engine na MG2 motor zitakua zafanya kazi kwa pomoja ili kutoa nguvu dereva anahitaji kwa ajili ya hiyo speed ya juu, the reduced fuel efficiency at high way speed isnt that much because of absence of regenerative braking....

Unless otherwise hii gari ni gari nzuri sana mkuu.. na huto jutia kuinunua..

Maelezo yameshehen content safi!

Naomba ntoe elimu kuhusu hybrid car.

Gari hybrid kuna za aina mbili. Kuna ambayo ina mpaka mfumo wa kucharge kama simu(plug-in hybrid) na hybrid car isiyo kua na sehemu ya kucharge kwenye soketi ya umeme(non plug-in hybrid car)

Sasa for car to qualify to be hybrid car ni kwamba inakua na injini na high voltage battery (lakini pia inakua na betri ndogo ya gari kama hizi tulizozoea)

Na inakua na mota mbili (MG1 na MG 2) hizi mota moja MG2 ndio inayopeleka nguvu kwenye matairi na hii mota pia huwa. Imeungwa kwenye injini ambapo wakati nguvu nyingi za kupush gari zinapo hitajika basi injini uingia kati na kusaidiana na mota (MG2) kutembeza gari.

Mota ya (MG1) kazi yake yake ni kuchaji high voltage battery wakati injini inapokua inawaka na pia hii ndio mota inayo washa injini pia. (Kumbuka hybrid car haina starter.

Kazi ya high voltage battery ni ku power MG2 mota, ku power ac compressor (kumbuka compressor ya hybrid car hizungushwi na belt kama conventional car, na pia hii hybrid battery (high voltage battery) ndio inayo charge ile betri ya v 12 kupitia mfumo wa DC to DC inverter (hii betri ya volt12 ni ku kupower all 12v electric equipments kama radio,taa za gari ntc

Sasa hybrid car inavofanya kazi ni kuna kitu kinaitwa hybrid management system kipo pale mbele ya engine compartment (primary computer for hybrid car).. kazi ni kumanage mfumo mzima wa high voltage na hybrid. Hapa ni kwamba injini inafanya kazi kama jenerata inachaji betri. Then betri ikifika level ambapo kumpyuta itaona inafaa injini inazima ila vitu vingine vinaendelea kama ac operation, car movement pale betri ikienda low voltage utasikia injini inawaka yenyewe kucharge betri tena.. hapa ndo fuel efficiency ya hybrid cars inapotokea..

kwa hybrid ambayo unachaji pia kama tesla yenye inakua imeongezea source moja ya kucharge hybrid battery.. ambapo unaweza toka nyumban battery imejaa charge baada ya kucharge usiku kucha, gari ikatembea,, sasa charge ya betr ikikaribia kuisha automatically engine itawaka kuichaji betri huku gari inatembea badae kama sekunde 3 kama gari ipo stationary ijini itazima ila kama gari inatembea injini inaweza waka dakika moja then ikazima yenye ukaendelea na umeme( kuifupi driving circumstances ndo zina determine frequency ya injini kuwa na kizima)

Hybrid car zinakitu kinaitwa regenerative braking. (Unapofunga brake badala ya gari kutumia brake calipers kufunga brake ni MG1 mota ita engage na injini inazima alafu tairi zinaizungusha MG1 mota kwa ajiri ya kucharge hybrid battery. Na ndo maana ukiwa unaendesha hybrid car ukifungu brake utaona bars za battery zinaongezeka. Na pia kwakua brake hazitumiki sana, brake za hybrid cars hudumu muda mrefu sana kuliko gari za kawaida.

Hybrid car zipo na mode kadhaa za kuendesha gari(driving mode) 1 kuna EV(yaan electric mode only) 2 (Hybrid mode-yaan injini na mota vinafanya kazi kwa wakati mmoja kuendesha gari 3 ECOMode yaaan hapa gari ino- monitor inputs zake kwenye throttle pressings zako na yenye ku respond taratibu mpaka una gain moment ya ku accelerate fast. Pia kuna power mode hii sasa kama unataka drive aggressively. (Every driving mode has its own impact kwenya fuel consumption)

Now how to maintain hybrid cars (ishu kubwa najua ni betri) Hybrid cars are supper reliable (Toyota tu maana ndo wapo kwenye game mrefu) shida kubwa kinacho ua betri na joto.. like any other batteries, betri za hybrid cars zina ventilation mechanisms Ambapo zina hitaji proper air circulation kwa ajili ya cooling(ukiwa na hybrid car mfano toyota Prius kwenye kiti cha nyuma kuna mahala utakuta kuna vents, hizi vents ni for fan to suck in air for cooling battery sasa huwa kuna filter ambayo with time hujaa vumbi na kua affect airflow volume na hatima battery kuchemka na kuanza kupoteza storage capacity, ila ukizingatia kusafisha filters gari inakaa muda mrefu sana. Imagine prius zinafika mpaka km400,000 with original battery..

Pia hizi battery huwa zinakua na pack za betri za volt kama 1.5 ambazo zina pangwa in series mpaka zinafika volts 300+ sasa kuna kua na battery modules zinazo monitor every single cell ya kwenye hybrid battery, so kukitokea kuna variation kubwa ya voltage discharge hata kwa cell moja, red triangle itawaka kiashiria kuna tatizo kwenye hybrid battery. So ukichomeka scanning machine ambayo ni advance itakuonyesha ni cell zipi zinashida.. so badala ya kununua hybrid battery yote fund anaweza fungua battery backs na ku replace pack ilio nashida akafanya battery balancing akarudisha maisha yakaendelea (note: hybrid system involves high voltage DC and AC na wire zake utazitambua kwa rangi zinakua na rangi ya orange hivo fundi wakutengeneza hii gari should be professional person who knows how hybrid system works lasivo mtu anaweza poteza maisha)

Ila msi site nunua Hybrid cars.. tena ukiwa ni mtundu hybrid car can be used as generator to power a house-using dc to ac inverter. Ambapo dc cables zinatika kwenye betri ya v12 unazipeleka kwenye inverter, then inverter ina convert ile v12 to Ac 220v na watt 2000 kama inverter yako ni ya watt 2000 baada ya hapo you have proper off grid electricity to power your various electric equipments. Angalia wazungu wanavo fanya camping na toyota Prius hadi uta enjoy..

Naomba niishie hapa.

Uko sahihi ila kwenye categories za hybrid kuna aina 2.
1.Convetional hybrids (Traditional)
2.Plug-in hybrids electric vehicles (PHEV)

Hapo kwenye conventional ndio penye hizi gari mithili ya Prius. Zinatumia Engine na Motors kutengeneza motion ya gari! Battery inachajiwa through generative braking tu!

Ukija kwenye PHEV hizi ni advanced ambazo battery inapokea charge kupitia regenerative braking pamoja na power outlets za majumbani! Hizi ni hybrid ambazo unaweza kuzichaji na zikatembea in isolation ya Engine kwa umbali flani then charge ikiisha engine ina kick in!

Kwa advancement zilizopo kwa sasa tunaenda kwenye aina ya 3 ya gari ambazo zinaitwa BEV ambayo ni kifupisho cha Battery Powered Electric Vehicle. Katika kundi hili ndipo wapo wakina Tesla ambao gari zao zina motor tu pekee bila engine. Wako wengine sana wameingia katika hili kundi ikiwamo kampuni za kichina ambazo zinachuana na tesla na almost kila kampuni kubwa wana gari ya BEV kwa mwaka huu! Toyota ana plan kutuletea hii gari mwaka 2022 akiwa ame patner na subaru! Inaitwa Toyota BZ (Beyond Zero) huku Lexus wakija na LF-1 (Limitless Electrified).

Nikweli Ukisoma kwa andiko langu nimeandika hybrid cars zipo za aina mbili... Wewe umeziita conventional Hybrid.... Mimi nkaita non plug-in hybrid car...

Ipo hivi Toyota wame opt hybrid kwakua ni gari ambazo ni self charging.. hata kama ni plug-in..

Tofauti hizo ambazo ni pure electric cars ambazo zinatumia battery tu... Disadvantages ya hii gari inayotumia battery peke yake ni kwamba unahitaji kipita kwenye charging points kuijachaji (fast charging infrastructures si nyingi dunianu hivo ukinunua gari kama tesla, nisssan leaf ukaja nayo bongo ina maana huwezi safari nayo toka dar kwenda mwanza kwakua betri itaisha charge na utahitaji kuichaji sasa shida itakuaja hapa yes unaweza ichaji kwenye socket ya nyumban but it will take days to have it full charged na ndo maana tesla ka install high voltage fast chargers kwa ajili ya gari zake, but with hybrid car (yaan ina umeme na injini ya kawaida) huta kutana na haya majanga ya kushiwa chaji ya betr then unabaki stranded njiani kwakua ilivokua designed hybrid car ni kwamba battery ikiwa imepungua charge below a certain level, engine kick-in to charge the battery after few seconds injini inazima na hata ukiwa na plug-in Hybrid car battery ikiisha injini itawaka ku charge huku unaendelea na safari (talking from experience)

Utofauti wa hybrid car na pure full electric car ni ukubwa wa battery.. Hybrid inakua na battery si kubwa sana kama pure electric car.. na ndo maana distance coverage in electric mode (EV mode) ya gari ambayo ni pure electric na ambayo ni hybrid ni tofauti... Mfano tesla anaweza kwenda umbali wa km 400 kwa umeme tu wakati Hybrid cars tena hizi latest ambazo ni plug-in ndo zaweza fika umbali wa 50km kwa umeme bila injini kuwaka (na hapa nu kama watembea speed ya kawaida)

So kifupi toyota wame opt Hybrid car kwakua hawa-limit kwenye kuuza magari yao .. tofauti na tesla ambapo ukinunua tesla unakuwa unawaza namna ya kuichaji ili utumie while with hybrid huna hizo stress.

But ndio maana nikasema tunaenda advancement ya pure electric kwa sasa soko limechangamka kaka!

Toyota analeta kitu pure electric mwakani hapo! Kitakuwa na solid state battery ambalo linaweza kuwa 80% charged ndani ya dakika 10! Very durable compared na hizi Li-ion batteries zilizopo sokoni! Wame patner na Panasonic kuhakikisha hilo linawezekana.

Mercedes ana EQS full electric!
Audi ana E-Tron full electric
BMW nae ana yake
VW pia anacho cha kwake

Inshort Tesla anakwenda kukumbana na ushindani wa hali ya juu. Future is electric kwa wenzetu huko! Nawaza kama ningekuwa Mo au mtu mwengine mwenye hela ningeanza kuwekeza Fast Charging points Around Town najua baada ya miaka 5 mbele watu wengi watakuwa wameanza kununua Plug-ins na ku abandon mafuta!

Usemacho ni kweli kabisa tec ya battery inaenda ina improve sana with time... Na kwa nature ya uchumi wetu kuhamia kwenye pure electrified cars may take decades kwakua vipato vyetu wengi ni wa kukunua gari za zamani, yaan mpaka circle ifike ya sisi kununua hizo gari technologia ilisha pitaga zaman, we imagine hata mifumo yetu ya tax assessment sijui kama hata tra tax calculator ipo configured kuweza hata kumsaidia mtu mwenye intention ya ku import electric car inaweza msaidia kupata hata indicative tax rate tu anayotarajia kulipa endapo ataagiza hilo gari (just out of curiosity)

So investment in fast charging infrastructures it has to be long term investment ambayo iko properly assessed na executed ili ije kukulipa in long run basing na mazingira yetu ya kibongo.. ila dah technology inakimbia sana na sie tupo nyuma.

Si tuko zama za mawe! Unajua Prius Hybrid tech has two decades mpaka sasa! Ilianzaga early 2000’s kwa wenzetu huko leo sisi 18- 20 years ahead ndio tumeweza afford!

Sema kwa mujibu wa Toyota wakifanikisha wanasema gari zao zinaenda kufanya mapinduzi hata bei ya EV’s itakuwa chini compared na ICE’s

Usipo jua namna ya kuitunza battery ya high voltage inaweza ika fail prematurely (mfano kuobadirisha air filter ya battery/uki interfere cooling mechanisms ya Hybrid battery.

Running car out of fuel hii ni shida kidogo..ukiishuwa mafuta na ukaendesha gari mpaka battery ikaisha kabisa kiasi kwamba computer itapo command injini iwake lakini kwakua hakuna mafuta injini ikashindwa kuwaka huwa inaleta shida...gari inaweza kukulete DTC (diagnostic trouble codes) ambazo itakulazimu kutumia scanner ili uzi clean ndo gari iwake

HID headlights zake uungua (kwa generation 2 na 3 sina uhakika na hizi generations nyingine...but uki install led bulb problem inakwisha,

Not every driving situations gari itakunali kwenda kwenye EV mode.

But all these ni issues ndogo ambazo kutokona na ubora wa gari si vitu vikubwa vya kukufanya usinunue hizi gari hasa toyota( note: kumbuka haya yote na ongelea Toyota Prius kwakua ndo nauzoefu nayo) yawezekana hizi issues zikawa chache zaidi kwa Toyota nyingine

Na inakua na mota mbili (MG1 na MG 2) hizi mota moja MG2 ndio inayopeleka nguvu kwenye matairi na hii mota pia huwa. Imeungwa kwenye injini ambapo wakati nguvu nyingi za kupush gari zinapo hitajika basi injini uingia kati na kusaidiana na mota (MG2) kutembeza gari.

Mota ya (MG1) kazi yake yake ni kuchaji high voltage battery wakati injini inapokua inawaka na pia hii ndio mota inayo washa injini pia. (Kumbuka hybrid car haina starter.

Kazi ya high voltage battery ni ku power MG2 mota, ku power ac compressor (kumbuka compressor ya hybrid car hizungushwi na belt kama conventional car, na pia hii hybrid battery (high voltage battery) ndio inayo charge ile betri ya v 12 kupitia mfumo wa DC to DC inverter (hii betri ya volt12 ni ku kupower all 12v electric equipments kama radio,taa za gari ntc

Sasa hybrid car inavofanya kazi ni kuna kitu kinaitwa hybrid management system kipo pale mbele ya engine compartment (primary computer for hybrid car).. kazi ni kumanage mfumo mzima wa high voltage na hybrid. Hapa ni kwamba injini inafanya kazi kama jenerata inachaji betri. Then betri ikifika level ambapo kumpyuta itaona inafaa injini inazima ila vitu vingine vinaendelea kama ac operation, car movement pale betri ikienda low voltage utasikia injini inawaka yenyewe kucharge betri tena.. hapa ndo fuel efficiency ya hybrid cars inapotokea..

kwa hybrid ambayo unachaji pia kama tesla yenye inakua imeongezea source moja ya kucharge hybrid battery.. ambapo unaweza toka nyumban battery imejaa charge baada ya kucharge usiku kucha, gari ikatembea,, sasa charge ya betr ikikaribia kuisha automatically engine itawaka kuichaji betri huku gari inatembea badae kama sekunde 3 kama gari ipo stationary ijini itazima ila kama gari inatembea injini inaweza waka dakika moja then ikazima yenye ukaendelea na umeme( kuifupi driving circumstances ndo zina determine frequency ya injini kuwa na kizima)

Hybrid car zinakitu kinaitwa regenerative braking. (Unapofunga brake badala ya gari kutumia brake calipers kufunga brake ni MG1 mota ita engage na injini inazima alafu tairi zinaizungusha MG1 mota kwa ajiri ya kucharge hybrid battery. Na ndo maana ukiwa unaendesha hybrid car ukifungu brake utaona bars za battery zinaongezeka. Na pia kwakua brake hazitumiki sana, brake za hybrid cars hudumu muda mrefu sana kuliko gari za kawaida.

Hybrid car zipo na mode kadhaa za kuendesha gari(driving mode) 1 kuna EV(yaan electric mode only) 2 (Hybrid mode-yaan injini na mota vinafanya kazi kwa wakati mmoja kuendesha gari 3 ECOMode yaaan hapa gari ino- monitor inputs zake kwenye throttle pressings zako na yenye ku respond taratibu mpaka una gain moment ya ku accelerate fast. Pia kuna power mode hii sasa kama unataka drive aggressively. (Every driving mode has its own impact kwenya fuel consumption)

Now how to maintain hybrid cars (ishu kubwa najua ni betri) Hybrid cars are supper reliable (Toyota tu maana ndo wapo kwenye game mrefu) shida kubwa kinacho ua betri na joto.. like any other batteries, betri za hybrid cars zina ventilation mechanisms Ambapo zina hitaji proper air circulation kwa ajili ya cooling(ukiwa na hybrid car mfano toyota Prius kwenye kiti cha nyuma kuna mahala utakuta kuna vents, hizi vents ni for fan to suck in air for cooling battery sasa huwa kuna filter ambayo with time hujaa vumbi na kua affect airflow volume na hatima battery kuchemka na kuanza kupoteza storage capacity, ila ukizingatia kusafisha filters gari inakaa muda mrefu sana. Imagine prius zinafika mpaka km400,000 with original battery..

Pia hizi battery huwa zinakua na pack za betri za volt kama 1.5 ambazo zina pangwa in series mpaka zinafika volts 300+ sasa kuna kua na battery modules zinazo monitor every single cell ya kwenye hybrid battery, so kukitokea kuna variation kubwa ya voltage discharge hata kwa cell moja, red triangle itawaka kiashiria kuna tatizo kwenye hybrid battery. So ukichomeka scanning machine ambayo ni advance itakuonyesha ni cell zipi zinashida.. so badala ya kununua hybrid battery yote fund anaweza fungua battery backs na ku replace pack ilio nashida akafanya battery balancing akarudisha maisha yakaendelea (note: hybrid system involves high voltage DC and AC na wire zake utazitambua kwa rangi zinakua na rangi ya orange hivo fundi wakutengeneza hii gari should be professional person who knows how hybrid system works lasivo mtu anaweza poteza maisha)

Ila msi site nunua Hybrid cars.. tena ukiwa ni mtundu hybrid car can be used as generator to power a house-using dc to ac inverter. Ambapo dc cables zinatika kwenye betri ya v12 unazipeleka kwenye inverter, then inverter ina convert ile v12 to Ac 220v na watt 2000 kama inverter yako ni ya watt 2000 baada ya hapo you have proper off grid electricity to power your various electric equipments. Angalia wazungu wanavo fanya camping na toyota Prius hadi uta enjoy..

Naomba niishie hapa.

Ndugu....samahanisana, nina shida nawe, kuna jambo naomba ushauri, tafadhali naomba uniruhusu kupata namba yako kwa mawasiliano zaidi

Mafundi wapo...

Hybrid cars zipo na service costs ndogo kuliko conventional cars... Mfano na zenyewe zinatumia oil kwenye injini ila frequency ya kuchange engine oil si kubwa kama gari yakawaida kwakua Hybrid car injini huwaka mda mchache na kuzima... Tena ukiwa kwenye folen mfano na ac ipo on... Utaona injini inazimika baada kama dakika 4 utasikia inawaka kwa ajiri ya kuchaji battery then itaunguruma kama sekunde 20 itazimika but functions nyingine zote zitaendelea kufanya kazi kwakua kichafanya kazi ni umeme tu. Hapo hata oil aichoki haraka kama oil ya kwenye gari ambayo si hybrid..

Na kumbuka regular service ya gari ni oil changing pomoja na filter yake (oil ya hybrid car kama upo tz at least 5w-30 fully synthetic oil usiweke hizi oil za kawaida kama sae 40 au hizi wengi wamezoe ya 20w-50), airfilters changing (both engine and cabin-ile ya ac) na brake pads sasa kwa Hybrid hivi vyote vinachukua muda kubadirisha... Hasa brake unaweza kuta gari inafikisha hadi km 200,000 ujawah badiarisha brake pads kwakua brakea zake hazitumiki mara kwa mara(regenerative braking ndo ufanya kazi mara nyingi)

Vingine ni vya kawaida.. ishu kama plug, kubadiri betri ile ya volt12, kusafisha egr valves kama ikijaa carbon, shocks absorbers na buahing hizi zipo hapa bongo (kumbuka uzuri wq toyota vitu vingi vya gari zake vinakua standard ni kufanya kuweza kuingilia kwa baadhi ya vitu vya gar zake hasa huku kwenye suspension systems

And the other major components they are too reliable (vitu kama car computers, engines, hybrid batteries, both motors yaani MG1 na MG2 zito za patikana ingawa kwakua hizi ndo za tengeneza transmission system, ikitokea zimekufa wewe nunua gearbox mpya kama tunavofanya hizi gari za kawaida.

Na ikitokea issue ni battery ya Hybrid ndo imekufa kuna namna nyingi na cheap ya kurekebisha kama fundi anajua achofanya. Unless una replace battery pack nzima ambayo haichukui hata nusu saa kubirisha..

Zingatia maji yasiingie mahala battery inakaa... Unapokua na hybrid car jitahidi kujua location ya battery zote mbili ili ujui namna ya kuilinda na maji.. pia kuzingatia kusafisha filter ya hewa inayokaa kwenye hybrid battery (maana hii ndo chanzo kikuu cha kuharibika kwa hizi battery) hakikisha battery inapata hewa ya kutosha.. (hizi gari kuna ambazo zina battery ya lithium ion na nyingine ni nickel cadmium sasa kila battery ina advantagea na disadvantages zake ingawa zote zinatengeneza joto zinapokua zinafanya kazi kama vile betri za simu.. sasa zinahitaji hewa ya kutosha ili ziweze kufanya kazi na kudumu kwa muda mrefu... Na kwa namna toyota walivo design kila battery pack inayotengeza hybrid battery ina temperature sensor kwa ajili ya monitoring ya temperature for every individual battery pack.. hii inasaidia effective protection ya battery when subjected to high temperature beyond required range..na hii ndo utakuta kuna fan ambayo inakaa kwenye kiti cha abiria kwa chini (kwa Toyota Prius) ambapo rotation speed yake inabadirika kulingana na temperature level ya battery. (Kwa watu wa dsm kama una gari Hybrid tumia AC as much as possible unapotumia hii gari hii itasaidia feni ya battery ku suck in cool air ambayo itakwenda kupoza battery..

Pia hii gari ni rahisi kufanya diagnosis kwa kutumia diagnostic machines kwakua zinakutajia specific problem na hata kama nu battery unaweza zoom in kwakila battery pack individual na ukajua ni pack gan ubadirishe na kufanya charging balancing ili battery zote ziwe even kwenye charging na discharging.

Zingatia tu kua kwenye mfumo wa uzungushaji maji ya kupozea injini kuna ambazo zinakuja na electric water pump na kuna zinazokuja na non electric water pump-ambayo inazungushwa na timing chain..so kwa zinazokuja na electric water pump when check engine light is on haraka saana weka gari pembeni chunguza chanzo cha hiyo check engine light..kwakua kwa hii gari yenye electric water pump the only way kujua kua ni water pump ndio imekufa is through check engine light illumination.

Kitu kingine cha kujua hii gari unapata a very good gas mileage kwenye trip za mjini kwakua muda mwing regenerative braking system inafanya kazi(zile stop and go zinafanya regenerative braking ina jaza chaji battery wakati wa kusimamisha gari but for high driving kwa speed 90+ gas mileage inashuka kidogo kwakua muda mwingi injini inawaka ku keep up with driving needs za dereva..so hapa both engine na MG2 motor zitakua zafanya kazi kwa pomoja ili kutoa nguvu dereva anahitaji kwa ajili ya hiyo speed ya juu, the reduced fuel efficiency at high way speed isnt that much because of absence of regenerative braking....

Unless otherwise hii gari ni gari nzuri sana mkuu.. na huto jutia kuinunua..
