An EV charger is a device designed to supply electric energy to recharge plug-in electric vehicles (EVs), including battery electric cars (BEVs) and plug-in hybrids (PHEVs). Chargers vary in power levels: Level 1 (120V, slow charging), Level 2 (240V, faster for homes/public stations), and DC Fast Chargers (480V+, rapid charging for commercial use). Equipped with smart features like scheduling, energy monitoring, and connectivity via apps, modern EV chargers ensure efficient, safe, and user-friendly charging. Compatible with global standards (e. g., CCS, CHAdeMO, or Tesla's connector), they support sustainable mobility by reducing reliance on fossil fuels.
