Internal preheating refers to the process of heating the battery internally and can be divided into two groups. The first type, self-heating technology, preheats the battery utilizing cell energy. The second type, current excitation technology, uses applied current excitation to heat Li-IBs through an internal impedance.
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.
