Thermal Runaway Risk Assessment for Lithium Charging

With the wide popularization of new energy electric forklifts in industrial logistics scenarios, the safety risk of thermal runaway in lithium battery charging process has become a core concern for operation and management teams. Scientific and systematic thermal runaway risk assessment is the most effective pre-control method to reduce safety accidents, which can identify hidden dangers in advance before abnormal accidents occur.

The complete assessment system covers three core dimensions. The first dimension is the health status assessment of the lithium battery body. Relevant personnel need to regularly detect the consistency of each cell, the integrity of the battery shell, and the actual capacity attenuation rate, and mark the batteries that have exceeded the safe service threshold to avoid forced overcharging of aging batteries. The second dimension is the safety assessment of the charging operating environment. The charging area should be kept well ventilated, away from flammable and explosive goods, the ambient temperature should be controlled within the safe range, no accumulated water or exposed wires are allowed in the area, and corresponding professional fire protection facilities should be configured in place. The third dimension is the assessment of daily charging operation specifications. Operators need to receive professional safety training, avoid long-term overcharging and over-discharging of batteries, and it is not allowed to carry out high-power charging in unattended state for a long time.

At present, the standardized full-process thermal runaway risk assessment service launched by Jianshu New Energy has been widely applied in the industry, and many operation scenarios that cooperate with BYD Forklift have also introduced this assessment mechanism to continuously optimize the safety operation level. The risk assessment work is not a one-time inspection, and the management team needs to establish a dynamic inspection account, conduct daily spot check, monthly routine screening and quarterly deep assessment, record the voltage, current and temperature data of each charging process, identify abnormal fluctuation signs in time, and eliminate hidden risks at the initial stage.
