Electric vehicle (EV) batteries store energy to power electric vehicles, using lithium-ion or other advanced chemistries for efficiency and long-range performance. EV chargers are devices that replenish these batteries, available in various types such as Level 1 (slow charging), Level 2 (faster charging), and DC fast chargers (rapid charging). Together, they enable convenient and sustainable driving by ensuring that EVs are properly charged for daily use or long-distance travel.
