How is charging defined in the context of electric vehicles?

In the context of electric vehicles, charging refers to the process of supplying power to an EV battery. This is essential for replenishing the energy that the vehicle's battery has used during operation, allowing the electric vehicle (EV) to continue functioning. Charging typically involves connecting the EV to a power source, such as a home charging station or a public charging station, where electrical energy is transferred to the battery cells.

The definition of charging focuses specifically on the relationship between power supply and battery energy storage, highlighting the importance of maintaining the battery's charge to ensure vehicle operation. As electric vehicles rely entirely on their battery to power electric motors, effective charging mechanisms are crucial for the usability and efficiency of these vehicles. This definition distinguishes charging from other maintenance activities that do not involve restoring electrical energy to the battery.
