Abstract: This application provides a vehicle and a power battery heating apparatus and method thereof. In the method, when a current temperature value of a power battery is lower than a preset temperature value, and a heating condition of the power battery meets a preset condition, a three-phase inverter is controlled to cause a three-phase alternating current motor to generate heat to heat a coolant flowing through the power battery. A preset quadrature-axis current and a corresponding preset direct-axis current are obtained to control the three-phase inverter to adjust a phase current of the three-phase alternating current motor in the heating process, so that electromagnetic torque with a small torque value is outputted at a motor shaft. The electromagnetic torque causes the motor output shaft to output a pre-tightening force to the transmission mechanism, thereby eliminating an engagement gap and effectively avoiding jitters of the vehicle.

Abstract: A temperature adjustment mechanism for a vehicle includes a battery-applied pump and circulation paths, and adjusts a temperature of a battery chargeable from an external power supply outside the vehicle to be within a predetermined temperature range. The temperature adjustment mechanism further includes a vacuum insulation tank in which either cold water generated by a cold energy source or hot water heated by a hot energy source is stored according to an ambient temperature during charging of the battery from the external power supply. At a time of input and output of electric power in the battery excluding a charge from the external power supply, the vacuum insulation tank is connected to the circulation paths, the cold water or the hot water stored in the vacuum insulation tank is supplied to the battery by driving the battery-applied pump, and a battery temperature is kept within the temperature range.
