Abstract

The invention provides a power supply one-key start-stop device and method of a low-voltage energy storage system, the device comprises a battery module, a main control module, a communication module and a power supply module, the battery module has an on state and an off state, the main control module is used for sending a control instruction, the communication module is connected between the battery module and the main control module, the main control module sends a control instruction to the battery module through the communication module, when any on-off key of the battery module is closed, a state signal is sent to the main control module through the communication module, and the main control module sends a control signal to the battery module through the communication module, so that all on-off keys of the battery module are closed. The power supply module is connected with the main control module and the communication module and supplies power to the main control module and the communication module. The battery module of the device can turn off all switches in the system after an on-off key of any battery is pressed down, and sends a control signal to the battery after receiving a switching signal, so that one-key control of a plurality of battery packs is realized.

Description

technical field [0001] The invention relates to a battery management system of an energy storage system, in particular to a one-button start-stop device and method for a low-voltage energy storage system. Background technique [0002] With the continuous improvement of the carbon neutral industrial green development strategy, the energy storage business will continue to expand, especially in the intelligent control of BMS (Battery Management System, battery management system), the traditional manual control power switch adopts the form of mechanical switch , the mechanical switches of each power module are independent of each other. Under abnormal circumstances, it is necessary to manually turn on / off the power supply of the corresponding equipment one by one for maintenance, which is difficult to maintain and requires a lot of manpower. Therefore, be necessary to design a kind of power key start-stop device, to overcome above-mentioned defect. Contents of the invention ...
