In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model provides an optimize structure convenient to electric two wheeler lithium cell maintenance, including the group battery casing and arrange the lithium cell group in the group battery casing in, group battery casing inner space divide into big, little two parts through the baffle, and the lithium cell group is placed to the big part in space, and the power battery protection shield is placed to the little part in space, and the power battery protection shield passes through the bolt to be installed on the baffle wall.
The partition is L-shaped and the partitioned small space occupies one corner of the internal space of the pack case.
An external maintenance port is arranged on the outer side of the partial space for placing the power battery protection board.
The battery pack and the shell are fixed in a buffering mode through a damping object.
1. The utility model discloses optimize the position of power battery protection shield, move the casing by the upper cover in, reduced the volume of group battery greatly, the cost is reduced.
2. The utility model discloses to the drawing of connecting wire when having avoided the inspection of uncapping, guaranteed the security that the battery used, improved the reliability.
3. The utility model discloses increase external maintenance port, the balanced maintenance of power supply battery group uses, has improved maintenance efficiency greatly.
