Hybrid And Electric Vehicles: High Voltage System Overview by TRYGO(m): 7:18am On Nov 01, 2018 |
I did promised some months that I'd be dissecting more on the high voltage battery packs available on common hybrid vehicles on our roads. https://www.nairaland.com/4723120/hybrid-electric-vehicle-maintenance-highlander#72583267 Today, I would be focusing on two Toyota vehicles: A Camry and a Prius. Both vehicles are the most common hybrid electric vehicles you see on our roads. But with these majority share on the roads, so we got more battery issues we've noticed also. 1. A Camry hybrid vehicle, has a battery pack with a combined voltage of 244.8V. Serial individual cells arrangements are in the 1.2V(about six of them:7.2V) Total of 34 modules(not cell). Capacity 6500mAh 2. A Prius has 28modules arranged serially to give a total voltage of 201.6V(1.2V*28). Same capacity as the Camry 6500mAh. All Toyota nickel metal hydride batteries are rated 6500mAh in their hybrid vehicles. |

Documentation also. Documentation is always the key in this job. Don't assumed your "head" got you covered!

TRYGO:pls sir id like for you continue this lessons. its a lesson to be learned.im actually thinking of getting a prius late next year God willing.im even more confident now we have a repairs man in the house. whats your take on the prius sir? |
Re: Hybrid And Electric Vehicles: High Voltage System Overview by TRYGO(m): 7:51pm On Apr 29, 2019 |
@eherbal. Prius cars, are reliable, and durable. It all depends on the models you're opting for. Just bear in mind that whichever you're getting, you could set aside some kind of lump sum, if you can, just on case the HV battery, is in it's "declining" state already. Altwrnatively, in some instances, we'd replaced any defective module(s), and balanced up your existing pack. Regards, Joseph 08066643532 DW Nig Ltd Isolo, Lagos |
