Energy Stores in a Battery-Powered Car

1. Initial Energy Store at the Start:

   • When the battery-powered car is switched on, the energy store primarily consists of the chemical energy stored in the battery. This energy is measured in watt-hours (Wh) or kilowatt-hours (kWh).

2. Energy Store during Operation:

   • As the car operates, the chemical energy is converted into electrical energy, which powers the electric motor. This energy is continuously drawn from the battery while the car is in use.

3. Energy Store at the End:

   • At the end of the journey, the energy store can be quantified by the remaining chemical energy in the battery. This can be affected by factors such as the duration of the drive, the efficiency of the motor, and the terrain on which the car operates.

Summary

The energy store of a battery-powered car goes from an initial chemical energy at the start, gets partially converted to electrical energy during operation, and concludes with a remaining chemical energy store in the battery at the end of the journey.
