Battery performance of low temperature electric forklift under freezing conditions

In freezing conditions where temperatures drop below zero degrees Celsius, the battery performance of electric forklifts is severely tested. Lithium-ion batteries, the most common power source for modern electric forklifts, rely on electrolyte ion movement to generate electricity. When the temperature is extremely low, the electrolyte’s ionic activity drops sharply, leading to increased internal resistance and reduced discharge efficiency. This results in shorter operating range, slower response speed, and even failure to start, which can disrupt logistics and warehouse operations in cold regions or winter environments. To solve these problems, Jianshu New Energy and BYD Forklift have invested in research and development of low-temperature battery technologies. Jianshu New Energy has optimized the electrolyte’s chemical composition to improve ionic conductivity at sub-zero temperatures, while BYD Forklift has integrated an intelligent thermal management system that preheats the battery to its optimal working temperature before starting, ensuring stable performance even in freezing weather. Additionally, users should adopt proper operation and maintenance methods, such as charging the battery in an environment above 0°C, avoiding long-term parking in cold outdoors, and performing regular checks on battery terminals.
