Battery packs for all electric drive EVs can contain several hundred individual cells. Each cell has a nominal voltage of 3-4 volts, depending on its chemical composition. [citation needed] To assist in manufacturing and assembly, the large stack of cells is typically grouped into smaller stacks called modules.
A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
An explosion in one cell may ignite any combustible gas mixture in the remaining cells. Similarly, in a poorly ventilated area, connecting or disconnecting a closed circuit (such as a load or a charger) to the battery terminals can also cause sparks and an explosion, if any gas was vented from the cells.

Battery electric cars are becoming more and more attractive with the higher oil prices and the advancement of new battery technology (lithium-ion) that have higher power and energy density (i.e., greater possible acceleration and more range with fewer batteries). [12] Compared to older battery types such as lead-acid batteries.
Usually contains a stack of eight LR932 button cells shrink wrapped together. A27: GP27A MN27 L828 27A V27A A27BP G27A: 8LR732 (alkaline) 22 (alkaline) 12: 8.0 × 28.2 Used in small RF devices such as car alarm remote controls. Can also be found in some cigarette lighters. May be made of eight LR632 cells. BA5800: BA5800/U (LiSOCl 2) BA5800A/U ...
The future of clean car technology may very well be hydrogen fuel cells. While you can already drive one on the road today, filling it up conveniently is another matter. Hydrogen fuel cell cars ...
A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen.
