How To Charge Lithium Batteries In Cold Weather

Charging in cold weather necessitates a different strategy, which is essential if you want your investment to last. Almost every battery requires a more complex charging technique when the temperature drops. Lead-acid batteries have a smaller charging range than lithium batteries. Both batteries, however, must be charged at a slower rate than usual while remaining within their respective temperature ranges.

It is proportional to the charging rate that the battery suffers damage when it is charged at colder temperatures. If the temperature is between 32°F and 14°F, batteries cannot be charged at a rate higher than 0.1 c, but this is rarely feasible.

If the temperature falls between 14°F and -4°F, batteries cannot be charged at a higher temperature than.05C. Due to the fact that you may not know how cold it can get during a charging cycle, these charging rates will definitely increase charging duration and complicate the entire process.

In some situations, you could go to sleep in 40-degree weather and wake up to a cold snap at 18 degrees Fahrenheit. Your battery could suffer irreversible damage if you charged at a higher rate overnight.

It is important not to charge your batteries when they fall below freezing without reducing the charge current when the temperature falls below freezing. It can be difficult to accomplish this unless your BMS communicates with your charger and your charger can respond to the data it receives. The charge current must be 5–10% of the battery’s capacity if you charge below freezing.

The lithium batteries have cold-weather performance and can charge continuously at temperatures as low as -4 degrees Fahrenheit without a reduction in current. On the other hand, a lithium-ion battery that is charged at a temperature below zero will be permanently damaged. In the past, the only solution was to have the battery above freezing temperatures before attempting to recharge it without a battery management system (BMS) communicating with a charger that was programmed to reduce the current. At that time, you can recharge batteries only by putting them in a warmer environment or by wrapping them in a thermal blanket. There’s no need to sacrifice battery performance because of the cold weather.

We have a number of lithium battery PACK production lines, aging, capacity division and other production equipment and a large number of experienced industrial workers.
