The invention provides a protection device of a power supply distribution unit, the power supply distribution unit comprises n relays, each relay is correspondingly connected with a power supply module, a first static contact of each relay is connected with a positive electrode of the corresponding power supply module, a first movable contact of each relay is connected with a positive electrode of a to-be-charged battery, and a second static contact of each relay is connected with a negative electrode of the to-be-charged battery. A second movable contact of each relay is connected with the negative electrode of the corresponding power supply module, a second static contact of each relay is connected with the negative electrode of the battery to be charged, n is a positive integer, the protection device comprises n first detection circuits, and each first detection circuit is connected with the positive electrode of the corresponding power supply module and the negative electrode of the battery to be charged; and each second detection circuit is connected with the positive electrode of the battery to be charged and the negative electrode of the corresponding power supply module. Therefore, whether the first static contact and the first movable contact of the relay are adhered or not and whether the second static contact and the second movable contact of the relay are adhered or not can be quickly and accurately detected.

    本发明提供一种电源分配单元的保护装置,电源分配单元包括n个继电器,每个继电器均与一个电源模块对应相连,其中,每个继电器的第一静触点均与对应的电源模块的正极相连,每个继电器的第一动触点均与待充电电池的正极相连,每个继电器的第二动触点均与对应的电源模块的负极相连,每个继电器的第二静触点均与待充电电池的负极相连,n为正整数,保护装置包括:n个第一检测电路,每个第一检测电路均与对应的电源模块的正极和待充电电池的负极相连;n个第二检测电路,每个第二检测电路均与待充电电池的正极和对应的电源模块的负极相连。由此,能够快速准确地检测出继电器的第一静触点和第一动触点、第二静触点和第二动触点是否发生黏连。
