Solutions for low temperature charging of Lithium Batteries

1. Heat the battery pack

If you do not consider the heating of the battery pack, it is basically impossible not to lose capacity. After all, your temperature 

is -25 degrees. Such a low-temperature environment is simply charging at room temperature. Low-temperature discharge will 

cause loss of battery capacity, not to mention that you still need to Low temperature charging. Recommended Action: 

Warm the battery pack.

2. Reduce charging speed

At -20°C, if you charge a ternary lithium battery at a speed of C/30, the final capacity is only 77% of the nominal. 

If you reduce the charging speed to C/100, the final capacity can reach 100%, but it will take 4 consecutive days. 

To fully charge a battery. Therefore, you can consider slow charging first to increase the battery temperature, and then

switch to fast charging.

3. Increase battery temperature

Charge in your room whenever possible
