AI Customer ServiceBattery pack low-temperature charging preheating strategy The required charging time of the battery pack depends on its state of charge before charging, the ambient temperature during charging, and the insulation effect of the battery pack.
The decrease of battery pack temperature during charging depended on the heat dissipation rate of battery pack to environment. After stopping charging, the rate of temperature decrease was approximately constant, about 0.1 °C/min. Improving insulation measures could reduce this rate.
To improve the low-temperature charge-discharge performance of lithium-ion battery, low- temperature experiments of the charge-discharge characteristics of 35 Ah high-power lithium-ion batteries have been conducted, and the wide-line metal film method for heating batteries is presented.
Therefore, the heating target temperature that ensures the average temperature of the battery pack is above 0 °C during the charging process is not constant. It is necessary to study the battery low-temperature charging preheating strategy and adjust the battery preheating target temperature according to the actual situation.
The charge performance of the battery pack heated is improved significantly by heating. After the battery pack at −40 °C is heated for 15 min with 240 W power, its charging performance is close to the charging performance of the unheated cell at 0 °C.
As the battery pack is used, the insulation effect of the battery pack will deteriorate, and the heat dissipation rate will change accordingly. Therefore, the heating target temperature that ensures the average temperature of the battery pack is above 0 °C during the charging process is not constant.
