The invention relates to an energy supply method, a controller, a readable storage medium and a hybrid electric vehicle, and the energy supply method comprises the following steps: under the condition that the hybrid electric vehicle is in a pure electric driving mode, obtaining wheel end required power of the hybrid electric vehicle and a temperature value of a bidirectional DC/DC converter, the bidirectional DC/DC converter is used for providing electric energy of a power battery of the hybrid electric vehicle to the driving motor; determining the output power of the bidirectional DC/DC converter according to the wheel end demand power and the temperature value; and controlling the bidirectional DC/DC converter to perform electric energy conversion according to the output power so as to provide the electric energy of the power battery to the driving motor. Thus, under the condition that safe operation is guaranteed, the output power limit value of the bidirectional DC/DC converter is improved so that the power battery can supply more energy to the driving motor, the working condition power requirement can be met as much as possible, the starting frequency of an engine is reduced, oil consumption is reduced, and the user satisfaction degree is improved.

    本公开涉及一种供能方法、控制器、可读存储介质以及混合动力汽车,该供能方法包括:在混合动力汽车处于纯电动驾驶模式的情况下,获取混合动力汽车的轮端需求功率以及双向DC/DC转换器的温度值,双向DC/DC转换器用于将混合动力汽车的动力电池的电能提供给驱动电机;根据轮端需求功率以及温度值,确定双向DC/DC转换器的输出功率;根据输出功率控制双向DC/DC转换器进行电能转换以将动力电池的电能提供给驱动电机。这样,在保证安全运行的情况下,提高双向DC/DC转换器的输出功率限值以使动力电池更多供能给驱动电机,尽可能满足工况动力需求,减少发动机的启动次数,降低油耗,提高用户满意度。
