LONG-STANDBY ELECTROCHEMICAL APPARATUS, ENERGY STORAGE SYSTEM, AND ELECTRIC VEHICLE

Title:

LONG-STANDBY ELECTROCHEMICAL APPARATUS, ENERGY STORAGE SYSTEM, AND ELECTRIC VEHICLE

Document Type and Number:

WIPO Patent Application WO/2022/140883

Kind Code:

A1

Abstract:

The present application provides an electrochemical apparatus. The electrochemical apparatus comprises a battery management system, a battery unit, and a switch unit; the switch unit is electrically connected between the battery management system and the battery unit; the battery management system is used for obtaining a state of charge of the battery unit; and when the state of charge is less than a preset threshold, and the electrochemical apparatus does not obtain a charge current transmitted by an external charging device, the battery management system outputs a first signal to the switch unit, and the switch unit disconnects the electric connection between the battery unit and the battery management system according to the first signal. The present application also provides an energy storage system. According to the long-standby electrochemical apparatus, the energy storage system, and an electric vehicle provided by the present application, the electrochemical apparatus can maintain a long storage time when the state of charge is low and external charging cannot be implemented in time.
