Effective EV charging is about extending battery life. Fully charging or fully depleting the battery can reduce its life expectancy. Limit fast charging because the resulting heat may lead to deterioration and damage over time, and don’t leave the battery fully charged when you store your EV for long periods. Use the 80/20 rule when not taking your EV on long trips, trying not to let the vehicle’s state of charge fall below 20% and stopping the charging process at 80%. This will extend the life of your battery.
