Isolation system for charging and changing station battery pack, charging and changing station and isolation method

Abstract

The invention relates to the field of charging and changing, and particularly relates to an isolation system for a charging and changing station battery pack, a charging and changing station and an isolation method, so as to solve the problems that the existing battery pack thermal runaway fire control method is low in positioning precision and poor in fire extinguishing effects. The charging andchanging station comprises a battery rack, and multiple battery packs are stored on the battery rack. The isolation system comprises an acquisition subsystem, a battery transporting subsystem and a control subsystem, wherein the acquisition subsystem is at least used for acquiring the thermal runaway information of the battery pack; the battery transporting subsystem is used for transporting a thermal runaway battery pack to an isolation position; and the control subsystem is connected with the acquisition subsystem and the battery transporting subsystem respectively for controlling the battery transporting subsystem to transport the thermal runaway battery pack to an isolation position when the battery pack is in a thermal runaway state. Through the above arrangement mode, a battery packwith thermal runaway can be accurately positioned and the battery pack with thermal runaway is transported to the isolated position, the positioning precision of the isolation system is improved, andsecondary hazards can be effectively avoided.

Description

technical field [0001] The invention relates to the field of battery charging and swapping, in particular to an isolation system for a battery pack of a charging and swapping station, a charging and swapping station and an isolation method. Background technique [0002] In recent years, with the continuous development of new energy vehicles, the energy supply of new energy vehicles has also become a major concern of major manufacturers. Taking electric vehicles as an example, among many power-up methods, the power-swapping solution has become a solution highly recommended by major manufacturers due to its advantages such as less damage to the battery pack and providing a convenient and quick power-up experience for car owners. The power swap scheme is generally completed in the charging and swapping station. Specifically, the charging and swapping station is equipped with a battery rack and a power swap platform, and a battery swap between the battery rack and the power swap...
