Customer ServiceAs shown in Fig. 8, the liquid preheating system consists of a heater, a pump, a circulating pipe, and its control components . The operating process involves the liquid (e.g., silicone oil) heated by the heater flows between the cells by employing the pump, facilitating the transfer of heat from the liquid to the battery.
It could preheat the whole battery module to an operating temperature above 0°C within a short period in a very low-temperature environment (–40°C). Based on the volume average temperature, the preheating rate reached 6.7 °C/min with low energy consumption.
Discharge preheating techniques have good temperature rise rates but usually require a large amount of battery energy. DC preheating techniques are more damaging to a battery, and AC and pulse preheating techniques can effectively mitigate this damage.
The growth of lithium dendrites will impale the diaphragm, resulting in a short circuit inside the battery, which promotes the thermal runaway (TR) risk. Hence, it is essential to preheat power batteries rapidly and uniformly in extremely low-temperature climates.
For the preheating mode, adopting an inlet flow rate of 2 L·min –1, an inlet temperature of 15 °C, and a preheating time of 600 s is optimal by considering both heating performance and energy efficiency under a low ambient temperature (Ta) of −20 °C.
The operating process involves the liquid (e.g., silicone oil) heated by the heater flows between the cells by employing the pump, facilitating the transfer of heat from the liquid to the battery. The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance.
