Abstract
A 100% low floor trolley car battery assembly comprises a storage battery pack box and an isolation protection device box, a battery pack case door with case door handle is arranged at the top of thecase body of the battery pack, a battery pack in which a plurality of battery cells are arranged in series in a row or column, a separator is arranged around the battery pack and a fixing bracket is arranged on the inner wall of the battery pack box to fix the separator, at the side of the case body of the isolation protection device, an isolation protection case door with a case door handle is arranged. After the positive and negative cable of the battery pack enter the case body of the isolation protection device, a fuse 1 for charge-discharge overcurrent protection, a manual switch and a fuse 2 for discharge overcurrent protection are installed on the line, and then the cable is led out. The invention has the advantages of high integration degree, small volume and light weight, and meets the requirements of lightweight and space limitation. The battery isolation and protection device and the battery pack are arranged in different cavities, which enhances the safety and also facilitates the maintenance and replacement of the battery assembly.
