How is the high voltage battery in hybrid vehicles differ from the regular low voltage automotive battery?
- dtstellwagenLv 79 months agoFavorite Answer
Not all hybrids are identical, so answers can be somewhat inaccurate.
A normal car battery consists of six 2.1v cells, contained in a battery. The cells are connected in series to get 12.6 volts.
An electric or hybrid will have 200 to 300 cells of batteries that have 1.2 to 2.1 volts per cell. The cells will be divided into 30 or 40 batteries.

Yeah hardly a specific question. Generally...the low voltage battery starts the car. High voltage battery propels it when allowed.
High voltage battery is a complex component. Lots of individual cells connected together. Monitored for temperature and voltage with cooling fans or a liquid cooling system. All monitored by a control module. It' s big and heavy. Usually mounted low in the center of the vehicle.

Lots of ways. As others point out, the hybrid battery will be either NiMH (like my first gen Prius and Hondas, at least in past years) or lithium ion. It will have a bank of sealed cells interconnected with buses and will have temperature sensors and other monitoring features. There will be a disconnect plug, coaxial wiring (I think they have standardized on orange), and much higher energy storage. The hybrid system will have much more sophisticated controls than the regular 12V lead-acid systems do.

The low voltage battery won't kill you.

The same difference as 5 girls pushing, vs 100 men pushing

The voltage is higher, and they are lithium ion, not lead acid.

It holds more of a charge and is partially powered by using the brakes.
