How Lithium Batteries Behave at Minus 20 Degrees Celsius

Many industrial operation teams that use electric forklifts in high latitude areas or cold northern regions in winter pay close attention to the actual performance of lithium batteries under low temperature extreme conditions, especially the working status at minus 20 degrees Celsius. Under natural state without any auxiliary temperature control design, ordinary lithium batteries will show obvious attenuation of available discharge capacity at minus 20 degrees Celsius, the actual available capacity can reach about 60% to 70% of the nominal capacity at normal temperature, and the charging acceptance will also decrease significantly. If users conduct high current charging directly under this temperature condition, it may cause irreversible damage to the internal active material of the battery, and shorten the overall service life of the battery. For the special application scenario of industrial handling vehicles, the optimized lithium battery for electric forklift is equipped with a built-in intelligent thermal management system, which can activate the low power preheating mode immediately when the ambient temperature drops below the set threshold, and slowly raise the core temperature of the battery pack to the suitable working range, so as to maintain stable and continuous power output. Jianshu New Energy has completed thousands of simulated low temperature cycle tests for special lithium batteries for forklifts, to verify the long term operation stability of products under minus 20 degrees Celsius and other extreme working conditions. A large number of actual application data shows that the properly optimized lithium battery for industrial use can fully meet the daily handling operation needs under the ambient condition of minus 20 degrees Celsius after matching the correct operation specifications. BYD Forklift’s supporting lithium battery power units have also passed comprehensive low temperature adaptability tests before leaving the factory, to avoid unexpected operation failures in cold regions. For daily usage, it is recommended that operators try their best to park the forklift in a sheltered and thermal insulation charging area when not in use, do not carry out high current charging when the battery core temperature is too low, and activate the preheating procedure before formal charging. These simple operation habits can effectively extend the overall service life of the lithium battery pack, and reduce the comprehensive operation cost of the material handling fleet.
