The invention discloses a heat preservation circuit of a power battery, a vehicle high-voltage circuit and a vehicle, and the heat preservation circuit of the power battery comprises a heater which is arranged corresponding to the power battery; the vehicle-mounted charger is connected with the first external power source, the power battery and the heater and used for supplying power to the heater based on the electric energy of the power battery in a non-charging scene so that the heater can conduct heat preservation on the power battery; and in the charging scene, supplying power to the heater based on the electric energy provided by the first external power supply, so that the heater preserves heat of the power battery. According to the heat preservation circuit, a high-voltage framework of the vehicle is innovated and optimized, so that the heater is not directly connected with other high-voltage parts in parallel to take electricity any more, energy consumption can be reduced, and the service life of the high-voltage parts can be prolonged.

    本发明公开了一种动力电池的保温电路、车辆高压电路和车辆,动力电池的保温电路,包括:加热器,加热器对应动力电池设置;车载充电机,车载充电机分别与第一外部电源、动力电池和加热器相连,用于在非充电场景下,基于动力电池的电能给加热器供电,以使加热器对动力电池进行保温;以及,在充电场景下,基于第一外部电源提供的电能给加热器供电,以使加热器对动力电池进行保温。本发明的保温电路,通过创新优化车辆的高压架构,使得加热器不再与其他高压部件直接并联取电,从而能够降低能耗,并能够延长高压部件的使用寿命。
