Abstract: The present application relates to a method and system for determining parameters of battery pulsed heating. The reference potential of the anode of the lithium-ion battery is obtained in real time in the positive and negative pulsed heating process under various heating parameters. The relationship between reference potential and threshold potential indicates whether Li plating has occurred to the lithium-ion battery. When the reference potential is smaller than the threshold potential, the first heating parameters are adjusted to avoid Li plating and improve battery life. By recording the heating parameters when the reference potential is greater than the threshold potential, it can be ensured that the pulsed heating parameters have no significant impact on the life of the battery.
