How much energy can a battery preheat safely?
The system can preheat the battery safely in the capacity range of 20%–100%. When the battery pack is set in −20 °C, the effective electric energy can be increased by 550% after preheating. An energy conversion model is also built to measure the relationship between the energy improvement of battery and the energy consumption by preheating.
How do you calculate the heating power of a battery pack?
Calculate the sum of all the heat required to heat up the battery pack components and the heat dissipated by the box to obtain the total heat of heating. Then according to the specific requirements of the heating time, the corresponding heating power is obtained.
What is the heating rate of a battery pack?
Ruan et al. applied DC heating to achieve a heating rate of 18.7 °C/min of the battery pack at a heating current of 58.2 A. DC heating usually requires a large electric current to drive the small internal resistance of the battery and generate a high heating rate.
How to test the heating power of a battery pack?
To test the heating power, we select a column of two single battery modules in the battery pack for a heating experiment. Since the experimental battery pack is one-tenth of the number of battery modules in the battery pack, we also use one-tenth of the estimated heating power of the battery pack, which is 30 W.
What is the average temperature of the battery pack after preheating?
After about 40 min of preheating, the average temperature of the battery pack reached 16 °C. After stopping preheating, the temperature gradually decreased, and after 160 min, the average temperature of the battery pack dropped to 4 °C.
