EV Battery Care: Avoid Sun Exposure and Manage Charge Levels

Battery aging in new energy vehicles falls into two categories: calendar aging and cycle aging. Calendar aging is influenced by the state of charge during storage and ambient temperature, while cycle aging is related to the number of charge-discharge cycles, charging/discharging rates, and temperature. High temperatures accelerate calendar aging in lithium-ion batteries, but most electric vehicles are equipped with battery protection systems that automatically cool the battery when temperatures become excessive. Experts recommend maintaining the battery charge between 40% and 50% when a vehicle is parked for extended periods to slow down aging. After prolonged exposure to direct sunlight, it's advisable to avoid fast charging or sudden acceleration immediately, as these can exacerbate cycle aging. These maintenance principles also apply to batteries in smartphones and household appliances.
