What is battery preheating?
The ultimate goal of battery preheating is to recover battery performance as quickly as possible at low temperatures while considering battery friendliness, temperature difference, cost, safety and reliability. A systematical review of low temperature preheating techniques for lithium-ion batteries is presented in this paper.
Why is battery preheating important in cold climates?
Charging at low temperature will induce lithium deposition, and in severe cases, it may even penetrate the separator and cause internal short, resulting in an explosion. Therefore, battery preheating techniques are key means to improve the performance and lifetime of lithium-ion batteries in cold climates.
Why is it important to preheat power batteries quickly and uniformly?
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.
Is resistance preheating a good way to heat a battery?
Resistance preheating technique is low in price, but other indicators are poor. Although the direct conduction of the resistance shortens the heat transfer path, it is exposed to the air and loses a lot of heat. In addition, in practical application, this method is also limited by the shape of the battery.
Is the AC preheating method effective and battery-friendliness?
Therefore, the above research results further validate the effectiveness and battery-friendliness of the AC preheating method. A temperature-adaptive, deposition-free AC preheating method was proposed by combining the maximum allowable AC current and the heat generation rate model in the frequency domain by H. Ge et al. .
Can a battery be preheated at low temperatures?
In summary, an efficient and evenly preheating of the battery at low temperatures can be achieved by selecting the appropriate AC parameters. However, the impact of quantified AC on battery health remains unclear.
