Abstract

The invention relates to a mobile energy storage system based on modularization, and belongs to the technical field of mobile energy storage. The system comprises an energy storage battery, a direct current matrix switch module and an inversion module which are connected in sequence, and is characterized in that the direct current matrix switch module comprises a first direct current bus, a second direct current bus and a third direct current bus, the direct current input branch of the first direct current bus is connected with the energy storage battery, the direct current output branch of the second direct current bus is connected with the inversion module, the direct current input branch of the third direct current bus is connected with a rectification module, the output end of the inversion module is connected with an alternating-current matrix switch module, the output end of the module is connected with the rectification module, and the alternating-current matrix switch module is further connected with an alternating-current interface module and used for being connected with an alternating-current power grid or an alternating-current load. By means of switching control of all switches in the direct-current matrix switch module, mode switching of the grid-connected operation working condition, the off-grid operation working condition, the direct-current power supply working condition, the mobile charging station operation working condition and the like can be conducted, and the requirements of multiple application scenes can be met.

Description

technical field [0001] The invention belongs to the technical field of mobile energy storage, and in particular relates to a modular-based mobile energy storage system. Background technique [0002] The application scenarios of mobile energy storage power supply are very wide. For example, it can be used for temporary increase of power grid in areas with power shortage; or it can be used as emergency power supply in large-scale events and exhibition centers; or it can be used in emergency rescue and disaster relief, engineering operations, building construction, film and television shooting, etc. Scenes can be used as temporary power sources. However, the circuit design of the current mobile energy storage system is relatively simple, and can only meet the application requirements of a single scenario or two scenarios. Under the requirements of multiple application scenarios, different types of mobile energy storage power supplies need to be configured, which is expensive an...
