How Many Degrees Of Lithium Iron Phosphate Battery Resistance To Low Temperature?

The performance of conventional lithium iron phosphate batteries is affected at low temperature. At a low temperature of -20 ° C, the capacity attenuation of lithium iron phosphate batteries is about 50% of the original capacity. Low temperature will cause the internal reaction rate of the battery to slow down, the ion conductivity of the electrolyte will decrease, and the available capacity of the battery will be reduced.

Using proprietary battery raw material formula and innovative manufacturing technology, Zhongke low-temperature lithium battery can effectively improve the discharge performance of the battery at low temperature, reduce the internal resistance of the battery, and achieve the effect of high-speed discharge; Therefore, the low-temperature lithium battery has a longer life and stronger power. Discharging at 0.2c at a low temperature of -40℃, the low-temperature battery discharge capacity of Zhongke is still more than 80%.

The high temperature performance of lithium iron phosphate battery is superior, the high temperature peak is 550 ° C -600 ° C. The low temperature resistance of lithium iron phosphate battery is also relatively good. The normal working temperature can work normally at -20 ° C -50 ° C, the charging temperature is 0 ° C -50 ° C, not like the lead-acid battery.  In Winter below 0 ° C, the battery life is greatly reduced. Even less than half of the original, lithium iron phosphate battery will not, its low temperature resistance performance is not as good as ternary lithium battery, but under 10 ° C, the battery life will not have the slightest impact, under 20 ° C, the battery life will not be lower than the original 80%, you can rest assured in the cold Winter.

In addition, when the lithium iron phosphate battery is used in winter, it is recommended that the charging work be carried out indoors, which can be fully charged, the battery and charger are away from water sources and open flames, and do not be placed in a cold and humid environment for a long time.
