The 10-80% charging range represents the optimal balance between charging speed, battery health, and practical daily use.
EVs charge fastest in this range due to the charging curve. Below 10% and above 80%, charging speed significantly decreases to protect battery health.
DC Fast Charging: 20-45 minutes for 10-80%, Level 2 Home: 4-8 hours, Level 1: 24-40 hours. Times vary by battery size and charger power.
Regular charging in the 10-80% range maximizes battery lifespan. Frequent 100% charges or deep discharges can accelerate battery degradation.
