The invention relates to a non-contact power battery low-temperature heating and charging device. A charging relay is connected in series with a first rectifier filter and then the series unit is connected in parallel with a heating relay; a first end after parallel connection is connected with a receiving coil, and a second end after parallel connection is connected to each battery module selection switch; the heating relay is connected between a receiving device and a plurality of battery module end control switches; and whether to heat the specific battery module or not is determined basedon the on-off of the heating relay and the on-off of the specific battery module selection switch. A main controller acquires battery voltage, current and temperature information and calculates an optimal charging current, an optimal charging voltage, a heating current frequency and/or power required by the battery module, so that the state of a high-frequency alternating magnetic field emitted byan emitting device is controlled and heating is realized at the optimal heating current frequency and the heating current amplitude; the alternating current in the non-contact power battery chargingdevice is used for heating the power battery and thus an external excitation source or an independent excitation source does not need to be arranged and new equipment is not added.
