Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an open battery power distribution management system. Background technique [0002] Increasing the cruising range and fast charging of electric vehicles are two long-standing problems. The existing battery distribution management systems are generally closed systems and cannot use an external portable battery pack to increase the range. When the battery pack is discharged, the energy release is unbalanced, which reduces the battery life and power utilization. [0003] Chinese Patent Application No. 201711096641.1 discloses a battery management system and its application. The battery management system includes a battery pack and a booster module connected to the battery pack. The battery pack includes a plurality of battery cells connected in series. In isolation, the battery unit includes connected battery cells and an active balancing module; the boosting module is ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an open battery power distribution management system, which can flexibly adjust the capacity of the battery pack by setting a portable battery, and can effectively solve the charging problem of the battery pack by setting a charging contactor device, an output contactor device and a control device. For the problem of unbalanced energy release during discharge, by setting up one or more battery groups to work while other groups of batteries are charged, the energy management mechanism for one or more groups of batteries to work while other groups of batteries are charged is realized. The present invention Improve the battery life and power utilization and can flexibly adjust the capacity of the battery pack, improving the remote adaptability of electric vehicles
