Abstract

The invention relates to a modular battery system with a multilayer management system and structure. The battery management system is connected to hardware through connectors and cables, and performsdata interaction and instruction transmission through a data bus protocol. One system control unit can be equipped with a plurality of high-voltage main control units. High-voltage battery systems controlled by the high-voltage main control units can be combined in series or in parallel, or can be combined in series and parallel simultaneously. The high-voltage main control units are directly connected to the system control unit through connectors and cables to form the cascaded high-voltage battery systems. The multilayer management system and structure can freely combine battery management systems for different purposes according to actual application needs to adapt to battery systems for different application scenarios.

Description

technical field [0001] The invention belongs to the battery field and relates to a multi-level battery management system. Background technique [0002] The battery system, especially the battery system used in the uninterruptible power supply, energy storage equipment, and electric vehicles should be designed so that the battery system can meet the controllable energy and energy requirements of the uninterruptible power supply, energy storage equipment, and electric vehicles. Call for voltage requirements. [0003] In order to make this kind of dominant battery system meet the energy and voltage requirements in different application scenarios, it is necessary to have a corresponding battery management system combination strategy to combine related battery system modules, and operate according to the application requirements through the corresponding management architecture. In the low-voltage operation mode, only low-voltage power supply can be provided to the load, and in ...
