The invention relates to an electric vehicle power system and a control method of the electric vehicle power system. The method comprises the steps that under the condition that the electric automobile is in a running state, a bidirectional direct-current converter is controlled to convert a high-voltage power supply provided by a power battery into a 48V power supply so as to supply power to a first-stage distribution box, and under the condition that the current voltage exceeds a first threshold value, the bidirectional direct-current converter is controlled to charge the 48V battery so as to supply power to a second-stage distribution box; and under the condition that the current voltage is lower than a second threshold value, controlling the 48V battery to discharge. By adopting the method, the power supply strategy can be intelligently adjusted according to the current voltage condition, the stable operation of a vehicle electrical system is ensured, and the flexibility and reliability of the system are enhanced.

    本申请涉及一种电动汽车动力系统和电动汽车动力系统的控制方法。所述方法包括:在电动汽车处于行驶状态的情况下,控制双向直流变换器将动力电池提供的高压电源转换为48V电源,以为一级配电盒供电,在当前电压超过第一阈值的情况下,控制所述双向直流变换器为48V电池进行充电,在当前电压低于第二阈值的情况下,控制所述48V电池进行放电。采用本方法能够智能地根据当前电压情况调整电源供给策略,确保车辆电气系统的稳定运行,增强了系统的灵活性和可靠性。
