Abstract

Positive Temperature Coefficient(PTC) self-heating method of battery and experiment researches are conducted in this paper; the model of discharge internal heating and the model of PTC heating for battery are established; analyses of the internal and external heat characteristics of the battery and self-heating temperature field distribution of the battery are carried out. The accuracy of those models are verified by implementing the self-heating experiments. The discharge tests are carried out under the extreme low temperature and the results show that charge and discharge rate, capacity recovery are much better than that of external-supplied power heating.
