Abstract

The invention provides an energy storage system, a battery management method and system of the energy storage system. The core parameters collected by each BMU of the energy storage system are uploaded to the corresponding CMU, and then the corresponding CMU judges whether the corresponding battery cluster is in a failure according to the received core parameters and the collected battery clusterparameters; and if the corresponding battery cluster runs normally, the corresponding CMU uploads the corresponding battery cluster characteristic data to SMU via CAN communication, and if the batterycluster fails, the corresponding CMU uploads the corresponding record edict data to the SMU via Ethernet communication. Compared with the prior art, the real-time interaction requirement satisfactiondegree of large-capacity data in the energy storage system is improved.

Description

technical field [0001] The invention relates to the technical field of energy storage management, in particular to an energy storage system and a battery management method and system thereof. Background technique [0002] With the increasing application of electric vehicles, electrochemical energy storage has also been developed on a large scale in the power system. For the typical application capacity of the current stand-alone MWh level, the battery in the energy storage system usually consists of multiple battery clusters connected in parallel, and each battery cluster includes multiple battery cells connected in series. [0003] Because the battery is relatively fragile in the system, overcharging, overdischarging, high current impact, etc. will endanger the safety of the battery. Therefore, the energy storage system usually needs to be equipped with a battery management system (BMS) Real-time upload of collected information such as voltage, current, and temperature, an...
