What Is An Ev Battery

Both hybrid vehicles and EVs use high-voltage batteries known as traction batteries, but they use them in different ways:

  • Hybrid vehicles have traction batteries that work in conjunction with a small internal combustion engine to propel the vehicle forward and recharge the battery.
  • Plug-in hybrid vehicles take this concept a bit further by providing a slightly larger EV battery that can provide 15 to 42 miles of total range before the internal combustion engine kicks in to charge the traction batteries and provide forward motion.
  • Electric vehicles dont have any internal combustion engines. Instead, they use huge traction batteries to power the multiple electric motors in each vehicle.

Most EVs and hybrid vehicles also have auxiliary, 12-volt batteries to power low-voltage systems throughout the vehicle, but dont confuse these small batteries with the traction batteries that make these cars go.

Traction batteries are typically assembled in a series of battery modules that are connected to make a battery pack. Lithium-ion batteries are the most common type of battery module found in these battery packs.

To open the battery compartment cover, it is best to use a larger coin. This can be, as in the example shown here, a 2 EURO coin. This coin is placed diagonally in the slot where the key is folded. With a slight twist of the coin, you can then pry/lever open the lid.

The cover then hangs further back at one point. You can use a small screwdriver to open the battery compartment cover completely.
