Abstract

The invention discloses an energy storage system starting device and method, and energy storage system. The energy storage starting device comprises a battery pack, a charge-discharge module and a battery management system connected with the battery pack, and a first switch device connected in series between the battery pack and the charge-discharge module. The battery management system is connected with the first switch device when the battery pack is short of power to charge the battery pack, and the first switch device is disconnected when the battery pack is abnormally operated. The energystorage system starting device and method, and the energy storage system can be safely started when the battery pack is short of power so as to ensure the stable operation of the energy storage system and greatly prolong the service life.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an energy storage system starting device, a starting method and an energy storage system. Background technique [0002] In the battery management system, preventing overcharge and overdischarge are two important goals of battery management. However, during the long-term cycle use of the energy storage system, the battery will often be seriously overdischarged due to the abnormality of the battery itself or self-discharge. When the battery pack is charged again, abnormal operation will occur, the entire battery pack will not work normally, and the load powered by the energy storage system will stop running. The energy storage system has low reliability and high failure rate, which seriously restricts its development and application. [0003] Therefore, how to design a starting device for an energy storage system that can start safely after the battery pack is short of power is a...
