The invention provides a power
system and a battery heating method of a
hybrid car. The
system comprises a
battery pack, a battery heater, a battery manager, a distribution box, a
motor controller, an engine, a motor and a shielded
inductor. The battery heater is connected with the
battery pack; the battery manager is used for controlling the battery heater to heat the
battery pack at first power or second power under a condition that the
hybrid car is in an electric mode or
hybrid mode when the temperature of the battery pack is lower than a first
heating temperature threshold and residual electric quantity is higher than a driving electric quantity threshold. The
motor controller is connected with the motor and the distribution box, provided with a first input end, a second input end and a pre-charging
capacitor connected between the first input end and the second input end, and used for supplying power to the motor according to a control command and
voltage distributed by the distribution box. The shielded
inductor matches with the pre-charging
capacitor of the
motor controller. The power
system can realize heating, and is high in
heating efficiency, low in cost and high in practicality. The invention further provides the
hybrid car.
