The invention relates to the technical field of new energy, in particular to a power battery pack, a vehicle power supply system and a vehicle wherein the power battery pack comprises: a first power supply assembly for providing a high-voltage power supply with a voltage greater than a first preset voltage to the vehicle; the second power supply assembly is used for providing a low-voltage power supply with the voltage smaller than a second preset voltage for the vehicle, and the first preset voltage is larger than the second preset voltage; and the exchange assembly is used for isolating a first power supply area where the first power supply assembly is located from a second power supply area where the second power supply assembly is located, converting a high-voltage power supply of the first power supply area into a low-voltage power supply and controlling the second power supply assembly to output the low-voltage power supply according to the low-voltage power demand of the vehicle. Therefore, the problems that the cost of a new energy automobile battery supply system is high, the DCDC adaptable to the automobile type and the follow-up power is limited and the like in the related technology are solved.
本申请涉及新能源技术领域,特别涉及一种动力电池包、车辆电源系统及车辆,其中,动力电池包包括:第一供电组件,用于给车辆提供电压大于第一预设电压的高压电源;第二供电组件,用于给车辆提供电压小于第二预设电压的低压电源,其中,第一预设电压大于第二预设电压;交换组件,用于隔离第一供电组件所在的第一供电区域和第二供电组件所在的第二供电区域,将第一供电区域的高压电源转换为低压电源,并根据车辆的低压用电需求控制第二供电组件输出低压电源。由此,解决了相关技术中新能源汽车电池供应系统的成本高,DCDC适应车型和后续功率具有局限性等问题。
