Battery 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.
Many researchers have studied the low-temperature preheating technology of battery packs to improve the performance of power battery packs under low-temperature conditions. At present, the low-temperature preheating technology for batteries is mainly divided into internal heating technology and external heating technology [ 13 ].
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.
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.
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 ensure battery pack charging performance, we use 35 °C as the highest preheating temperature. When the calculated preheating target temperature exceeds 35 °C, we replace it with 35 °C and adopt multiple preheating methods at the same time.
