摘要： A battery thermal management system for a vehicle having a drivetrain. The thermal management system includes: a high-voltage propulsion battery, a waste-heat source of the vehicle drivetrain, and a battery heating circuit configured for circulating a battery coolant. The battery heating circuit includes a pipe being routed in the vicinity of, and spaced-apart from, the waste-heat source and configured for conveying the battery coolant for enabling the battery coolant within the pipe to heat-up by heat-radiation emitted from the waste-heat source and/or heat-convection through air from the waste-heat source to the battery coolant, and the battery heating circuit is configured for conveying the heated battery coolant to the battery for enabling heating of the battery by the battery coolant.

摘要： A battery heating method and a battery heating system for a vehicle battery. The battery heating system includes a vehicle battery, an auxiliary energy storage device, a direct current to direct current converter and a processing circuitry. The processing circuitry is configured to cause the battery heating system to operate in a first mode wherein the direct current to direct current converter is configured to control a current to flow through the vehicle battery in a first direction and operate in a second mode wherein the direct current to direct current converter is configured to control a current to flow through the vehicle battery in a second direction.
