1. Electric vehicle batteries may be damaged at extremely low temperatures: Electric vehicle batteries, especially lithium-ion batteries, can slow down their internal chemical reactions at extremely low temperatures, leading to a decrease in battery performance, such as slower charging speed, weakened discharge capacity, and even the possibility of inability to charge or a sharp drop in battery capacity. Long term exposure to such extreme low temperature environments may cause permanent damage to the battery.
2. Appropriate insulation measures can help protect batteries: Although batteries may be damaged at extremely low temperatures, proper insulation measures such as parking electric vehicles indoors or using battery insulation covers can effectively slow down the decline in battery performance and protect batteries from freezing damage.
3. Avoid frequent charging and discharging to protect the battery: In cold weather, frequent charging and discharging of electric vehicle batteries should be avoided as much as possible, as this will intensify the chemical reactions inside the battery and increase the risk of battery damage. At the same time, timely charging when the battery level is low is also an important measure to protect the battery and avoid excessive discharge.
