Battery changing battery box charging method system

Abstract

The invention discloses a battery changing battery box charging system which comprises a station control system, a plurality of chargers and a battery box, charging bins corresponding to the chargersare arranged in the battery box, battery packs are stored in the charging bins, the chargers charge the battery packs and are in communication connection with the battery packs, the station control system is in communication connection with the chargers, and the station control system receives feedback information of the chargers and issues an operation instruction to the chargers. A controller, an auxiliary power supply and an insulation detection circuit are arranged in each charger, and the auxiliary power supply and the insulation detection circuit are in communication connection with thecontroller; a BMS and a heat dissipation module are arranged in each battery pack; the auxiliary power supplies supply power to the BMSs and the heat dissipation modules through auxiliary power supplyloops; the insulation detection circuits are in communication connection with the battery packs through direct-current power loops, and the insulation detection circuits are used for insulation detection in the charging process; and the controllers are in communication connection with the station control system and is communicated with the BMSs through guide loops. The invention further disclosesa charging method of the system. Lightweight design is realized, and manufacturing and operating costs are reduced.

Description

technical field

[0001] The invention relates to the technical field of charging a car charging pile, in particular to a charging method and a charging system for a battery replacement box. Background technique

[0002] As a rapid energy supply equipment for electric vehicles, the power station needs to store a certain number of battery packs in the station, and configure a charger to supplement the battery packs. In order to ensure the smooth progress of the charging and battery replacement process, it is necessary to perform insulation testing on the charging main circuit during the charging process, and at the same time, provide working power for the battery pack cooling module. In addition, whether charging or not, the battery pack BMS needs to be in working condition, so as to transmit the battery pack status information to the station control system in real time. At present, in order to ensure the unification of the standards for the chargers used in the power station ...
