Abstract: A self-heating control circuit includes a control module configured to obtain a cell temperature of each of two battery packs connected in parallel and send a trigger signal in response to the cell temperature being lower than a threshold. The two battery packs include a first battery pack and a second battery pack. The control circuit further includes a switch module disposed at a charging and discharging circuit of the first battery pack. A control terminal of the switch module is connected to the control module and is configured to cut off the charging and discharging circuit upon reception of the trigger signal. The control circuit also includes an excitation module configured to form a path with the two battery packs upon cut-off of the charging and discharging circuit, and generate an excitation current, so that the excitation current flows back and forth between the two battery packs.

Abstract: An embodiment of the present application discloses a charging method, including: acquiring a state parameter of a power battery by a power conversion apparatus; setting a charging mode to a pulse charging mode by the power conversion apparatus when the battery temperature is lower than a first preset threshold; and converting charging power of a charging apparatus and then charging the power battery by the power conversion apparatus in the pulse charging mode. Through the technical solution, the power conversion apparatus acquires a battery temperature of the power battery, when the battery temperature is lower than the first preset threshold, the power conversion apparatus converts the charging power output by the charging apparatus, and outputs a pulse current to charge the tract battery, to prevent the charging apparatus directly charging the power battery in a low temperature, thereby ensuring the performance of the power battery.
