Generally, lifepo4 battery are power solution in a moderate climate.But we can still use them in some cold weather conditions with a little bit of knowledge.Self heating battery can also be a good choice.Let’s take a look at LiFePO4 batteries’ low temperature performance and how to keep them from packing up.
Lifepo4 batteries can be safely discharged over a wide range of temperatures, typically from –20°C to 60°C, which makes them practical for use in all-weather conditions faced by many potentially cold temperature applications including RVs and off-grid solar. In fact, lithium-ion batteries have much better performance at colder temperatures than lead-acid batteries. At 0°C, for example, a lead-acid battery’s capacity is reduced by up to 50%, while a lithium iron phosphate battery suffers only a 10% loss at the same temperature.
They worked, but that doesn’t mean they will always work. And they may refuse to take a charge. When exposed to very cold temperatures, there’s one rule to remember:
DON’T charge them when the temperature falls below 0°C or 32°F without reducing the charge current.
The only solution has been to heat the batteries to above freezing before charging.
1 – Batteries generate heat internally when they’re put to use. So, one quick and easy tip to make sure the battery is warm enough to accept a charge is to start your vehicle. A little bit of use will generate heat within the battery, taking it to within the safe charging threshold.
2 –Don’t leave them in the van overnight. Invest in an tote bag and load your batteries into it at the end of the day. Bring the tote into your home overnight, preventing the packs from experiencing a chilly night in the van!
3 –Wrapping them in a thermal blanket or placing a small heater near the batteries, ideally with a thermometer to monitor the temperature during charging.
These may not be the most convenient ways however. It will be more practical to choose a lifepo4 self heating battery with heated function for low-temperature use. Besides bluetooth function, our lifepo4 batttery can also add heated function to relieve customers’ winter range anxiety. The BMS brings with self heating function. When temperature is below 0℃, charging heating patch between cells will start to warm the inside of battery. So batteries still power you through the day, even in freezing temperatures.
