A traction battery, also known as an electric vehicle (EV) battery, is a rechargeable battery specifically designed to power vehicles. These batteries are widely used in electric cars, electric scooters, electric bicycles, and other electric vehicles.
A traction battery uses chemical reactions to store and release electrical energy. Typically, these batteries are composed of multiple cells that are connected to each other. Each cell contains positive and negative electrodes, which are separated by an electrolyte. Common types of traction batteries are lithium-ion batteries, nickel-metal hydride batteries, and lead-acid batteries.
When charging a traction battery, external electrical energy is used to reverse the chemical reactions in the battery. This process restores the electrodes to their original state and allows the battery to store energy. Charging usually occurs by connecting the vehicle to a charging station or a power outlet.
When the vehicle is in use, the stored energy in the traction battery is used to power the electric motor, which in turn drives the vehicle. The energy is released through the chemical reactions in the battery, as electrons flow from the negative electrode to the positive electrode via an external circuit.
The performance of a traction battery is measured by various characteristics, such as capacity (expressed in kilowatt-hours), charging speed, discharging speed, and lifespan. The development of traction batteries has advanced significantly in recent years, allowing electric vehicles to offer greater ranges and better performance.
Maintenance of a traction battery generally includes regular charging cycles, avoiding complete discharge, and protecting the battery from extreme temperatures. Additionally, there are specific recycling programs for traction batteries to ensure they are disposed of in an environmentally friendly manner when they reach the end of their lifespan.
