Abstract

The invention provides an automatic battery pack matching system. The system comprises a plurality of battery packs located on an automobile, a vehicle-mounted battery pack controller, an energy source station controller and a plurality of battery packs located on an energy source station, wherein one controller is arranged in each battery pack and the controller is used for acquiring state information of the corresponding battery pack in real time; the vehicle-mounted battery pack controller is used for receiving and analyzing the state information of the plurality of battery packs on the automobile in real time; when the battery packs need to be replaced, the vehicle-mounted battery pack controller is used for sending the state information of the battery packs needing to be replaced to the energy source station controller; the energy source station controller is used for calculating the state information to obtain the battery packs which can mostly meet the requirements of the energy source station. According to the automatic battery pack matching system provided by the invention, automation of battery matching and replacing can be realized and workers can be guided to replace the battery packs, so that the battery pack matching and replacing efficiency is extremely improved.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an automatic battery pack matching system. Background technique [0002] At present, the battery replacement between the battery replacement energy station and the battery replacement electric vehicle can only be roughly matched according to the battery capacity, and most of the matching is done manually, the matching efficiency is not high, and the effect is not good enough. [0003] The present invention analyzes the on-line state of the vehicle battery pack and the battery pack of the energy station, and automatically assembles groups according to the state information of the battery packs, thereby greatly improving the efficiency of battery replacement. At the same time, compared with manual matching only based on battery capacity, a comprehensive analysis of the state of the battery pack can greatly improve the accuracy of matching and improve the consistency between...
