Abstract
A voltage regulation circuit for traction battery includes a traction battery, a heating module, a charge/discharge interface, and a voltage regulation module. The heating module includes a power storage element and a switch module. The traction battery is connected in parallel to the switch module. An external charging and discharging device is connected in parallel to the traction battery through the charge/discharge interface. The voltage regulation module includes a plurality of switches and a power storage regulation element, and the plurality of switches and the power storage regulation element are disposed between the charge/discharge interface and the traction battery. The voltage regulation module and the switch module are configured to regulate, in response to a voltage regulation control signal, a charge/discharge voltage between the traction battery and the power storage element and a charge voltage of the external charging and discharging device for the traction battery.
