Description

Technical Field

[0001] The utility model relates to the technical field of bidirectional energy storage converters, in particular to a bidirectional energy storage converter. Background Art

[0002] A bidirectional energy storage inverter is a device that can play a key role in the electric energy storage system. It can convert the DC power generated in the process of renewable energy power generation into AC power and store the power so that it can be converted back into DC power for power supply when needed. At the same time, in the event of a grid failure or power outage, the stored power can be quickly converted into AC power and provided to users, ensuring the continuity and reliability of power supply. The bidirectional energy storage inverter module is mainly composed of power electronic devices, energy storage batteries and controllers.

[0003] Since the energy storage batteries inside the bidirectional energy storage inverter are connected by plugs and connecting wires, the plugs of the connecting wires are easily affected by external forces, resulting in unstable connections and affecting the reliability of power transmission. In addition, it takes a long time to fasten the energy storage batteries inside the bidirectional energy storage inverter with screws, which is inefficient, especially when the batteries need to be frequently installed and removed. In response to the above situation, we have introduced a bidirectional energy storage inverter. Utility Model Content
