Lithium batteries have an impact on range in winter. The working principle of a lithium-ion battery is that the internal electrolyte changes through chemical reactions, causing a potential difference between the positive and negative electrodes to generate current. In a low temperature environment, the electrolyte moves very slowly, which affects the transfer activity of lithium ions between the positive and negative electrodes, resulting in a decrease in the charging and discharging performance of the battery.
To put it simply, in a low temperature environment, it is not that the lithium battery is really discharged, but that it is powered but cannot be released normally. According to analytical data, the capacity of ordinary lithium batteries will be reduced by 20% at zero degrees Celsius, and when it reaches minus 10 degrees Celsius, the capacity may only be about half.
Detailed informationWhen the ambient temperature is below 0℃, when charging an electric vehicle, the system automatically heats the battery cells first. When the battery cell temperature exceeds 5℃, the system will automatically heat the battery cells. Really start loading the vehicle. Some electric vehicle owners may feel that the charging speed of electric vehicles suddenly slows down in winter. This actually means that there is additional time to heat the battery cells before recharging the vehicle.
Therefore, when car owners usually charge their cars, they should try to do so in underground parking lots, closed garages and other places. This will help improve battery activity, not only reducing loss of cruising range, but alsoimprove charging efficiency and save time.
