What are the preheating strategies in a battery module/pack level?

The preheating strategies need to be further explored in a battery module/pack level since cell temperature homogeneity in a pack is critical to the overall performance of the battery pack and would affect its aging processes.

How does battery preconditioning work?

Battery preconditioning causes the battery heating system to activate when a charging station is entered into the built-in navigation so that the car arrives at the charger with a warm battery capable of much faster charging than without preconditioning.

What is a battery-powered preheating case?

In this battery-powered preheating case, an additional amount of heat can be generated inside the battery owing to its internal resistance. This additional amount of heat can benefit the battery warm-up process by accelerating the cell temperature increase.

Do electric vehicles need a battery preheating strategy?

Battery warm-up/preheating is of particular importance when operating electric vehicles in cold geographical regions. To this end, this paper reviews various battery preheating strategies, including external convective and conductive preheating, as well as the latest progress in internal heating solutions.

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.

What temperature can a battery module preheat?

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.
