The invention provides a pre-charging device, a battery distribution box, a power battery pack and an electric vehicle. The pre-charging device comprises an insulating shell, a conductive connecting part and a pre-charging module, the conductive connecting part and the insulating shell are of an integrally formed structure, the pre-charging module is arranged in the insulating shell, and the pre-charging module is electrically connected with the conductive connecting part, so that the pre-charging device does not need to be matched with the pre-charging module by adopting a wire harness; and therefore, the condition that the thicker wire harness is not easy to bend in the limited space of the insulating shell can be avoided. The insulating shell and the conductive connecting part are of an integrally-formed structure, so that the conductive connecting part and the insulating shell are arranged compactly, the integration level of the pre-charging device is improved, the space position occupied by the conductive connecting part in the insulating shell is reduced, and the space utilization rate of the insulating shell is improved.
本发明提供一种预充装置、电池配电盒、动力电池包和电动汽车。预充装置包括绝缘壳体、导电连接部以及预充模块,导电连接部与绝缘壳体为一体成型结构,预充模块设置于绝缘壳体内,预充模块和导电连接部电连接,有助于预充装置无需采用线束来与预充模块配合,继而有助于避免较粗的线束在绝缘壳体有限的空间内不容易进行弯折的情况。绝缘壳体与导电连接部为一体成型结构,使得导电连接部与绝缘壳体之间排布得较为紧凑,提高了预充装置的集成度,有助于减少导电连接部占据绝缘壳体的空间位置,提高绝缘壳体的空间利用率。
