The invention discloses a power supply system applied to a new energy commercial vehicle and the new energy commercial vehicle, and relates to the technical field of batteries of the new energy commercial vehicle. The power supply system comprises a plurality of mutually connected battery boxes and a power distribution unit. And the power distribution unit can select at least one battery box from the plurality of battery boxes to supply power to the new energy commercial vehicle, and can also control charging and discharging among the plurality of battery boxes. The battery box comprises a shell, a high-voltage connecting unit, a liquid path connecting unit and a plurality of standardized power supply assemblies. The standardized power supply assembly comprises a battery cell support, a heat management module, a high-voltage integrated module and a plurality of battery cells. Each standardized power supply assembly comprises an independent thermal management module, and the thermal management module extends out of a liquid inlet and a liquid outlet. Therefore, the power supply system main body is composed of a plurality of completely consistent standardized power supply assemblies which are independently cooled, differentiated heat dissipation can be carried out on the battery cells at different positions, and the power supply system is low in cost, good in safety and high in expandability.

    本说明书公开了一种应用于新能源商用车的供电系统及新能源商用车,涉及新能源商用车的电池技术领域。该供电系统包括相互连接的多个电池箱以及配电单元。配电单元能够从多个电池箱中选择至少一个电池箱为新能源商用车进行供电,还能够控制多个电池箱之间的充放电。电池箱包括外壳、高压连接单元、液路连接单元及多个标准化供电组件。标准化供电组件包括电芯支架、热管理模块、高压集成模块以及多个电芯。每个标准化供电组件均包括独立的热管理模块,该热管理模块延伸出进液口以及出液口。可见,组成供电系统主体的是多个完全一致的标准化供电组件,且均独立散热,能够对不同位置的电芯进行差异化散热,且成本低、安全性好、可扩展性高。
