Why do electric cars need charging?

Answer: Batteries store limited energy

Batteries store limited energy ✓ — Correct! EV batteries store chemical energy converted to electricity. Driving uses this energy (motor, heating/cooling), depleting the battery. The stored energy must be replenished through charging.

Batteries leak electricity slowly — Wrong. Batteries don't leak significantly. EVs need charging because driving uses the battery's stored energy, which then needs replenishing.

Charging extends battery life — Wrong. Charging replenishes used energy, not extends battery life. Frequent fast charging can actually slightly reduce lifespan.
