The power path of the power distribution system and the energy-carrying battery charging power distribution system.
进一步的，由于动力电池和载能电池都是由多个电池构成的电池组，为了达到更好的系统性能，载能电池充电配电系统和动力电池充电配电系统中分别设置有电池控制器，可以控制电池组的电压、温度、电流等参数，其中，电池控制器和可以使用电动汽车领域中现有的电池控制器(例如：CN96110458.9、CN301640639等公开的电池控制器)。Further, since both the power battery and the energy-carrying battery are battery packs composed of multiple batteries, in order to achieve better system performance, the power-carrying battery charging and distribution system and the power battery charging and distribution system are respectively equipped with battery controllers , parameters such as voltage, temperature, and current of the battery pack can be controlled, wherein, the battery controller and existing battery controllers in the field of electric vehicles can be used (for example: battery controllers disclosed in CN96110458.9, CN301640639, etc.).
本实用新型还提出了一种移动充电车，包括上述任一所述的载能电池充电配电系统和动力电池充电配电系统。The utility model also proposes a mobile charging vehicle, which includes any one of the energy-carrying battery charging and distribution system and the power battery charging and distribution system described above.
至此，已经结合附图所示的优选实施方式描述了本实用新型的技术方案，但是，本领域技术人员容易理解的是，本实用新型的保护范围显然不局限于这些具体实施方式。在不偏离本实用新型的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本实用新型的保护范围之内。So far, the technical solution of the utility model has been described in conjunction with the preferred implementations shown in the accompanying drawings, however, those skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific implementations. On the premise of not departing from the principle of the utility model, those skilled in the art can make equivalent changes or substitutions to relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the utility model.
