Battery module and method for controlling charge and discharge

A method for controlling charge and discharge of a battery module, the battery module comprising:

• a battery body;
• an outer housing, the battery body being disposed in the outer housing;
• a heat conduction assembly, the heat conduction assembly being connected between the outer housing and the battery body in a heat conduction manner;
• a first heating member, the first heating member being connected to the battery body and configured to heat the battery body;
• a second heating member, the second heating member being connected to the heat conduction assembly and configured to heat the heat conduction assembly;
• a temperature sensor, the temperature sensor being configured to detect a temperature of the battery body and generate a temperature signal according to the detected temperature of the battery body;
• and a control assembly, the control assembly being electrically connected to the first heating member, the second heating member and the temperature sensor separately, and being configured to receive the temperature signal and control the first heating member and the second heating member according to the temperature signal;
• the method comprising the following blocks:
• S01:
• the control assembly receiving the temperature signal sent by the temperature sensor, wherein the temperature signal is generated by the temperature sensor according to the temperature of the battery body;
• S02:
• when a temperature Tx corresponding to the temperature signal doesn't exceed a temperature T0, the control assembly controlling the first heating member to heat the battery body, and the control assembly controlling the second heating member to heat the heat conduction assembly, wherein the temperature T0 is a temperature threshold.
