Abstract

The invention discloses a user-side distributed energy storage device, which comprises a mobile device, an energy storage box and a fire extinguishing system, and is characterized in that the energy storage box is mounted on the mobile device, and the fire extinguishing system is mounted on the energy storage box; the energy storage box comprises a box body, a plurality of battery modules, a plurality of battery supports, a battery management system, a first bidirectional inverter, a second bidirectional inverter and a monitoring system. The plurality of battery supports are distributed and mounted in the box body; the battery modules are mounted on the battery supports, and the plurality of battery modules are connected with the battery management system; and the box body is provided witha power grid side power interface and a user side power interface. Through the energy storage box, timely regulation and control of power grid power utilization are realized, and the power utilization experience of a user is improved; by arranging a heating device and a heat dissipation device, the environment in the energy storage box is kept in a constant-temperature state, and the service lifeof the battery module is prolonged; and through the fault detection device, the fault type is detected more accurately, the device is simple, and the detection range is wide.

Description

technical field [0001] The invention relates to the technical field of battery energy storage, in particular to a user-side distributed energy storage device. Background technique [0002] Distributed energy storage is a kind of energy storage that is mainly installed on the user side or the distributed generation side. It is mainly used to store excess distributed power generation energy and stabilize the fluctuation of distributed power generation output to reduce the impact on the distribution network. [0003] At present, the power grid is gradually using wind power and solar power for power generation. At certain moments, the generated power is too much, and the power stored in the energy storage station cannot be stored after reaching the upper limit, resulting in the loss of part of the energy. , there are some special time periods, users are in peak power consumption, and power consumption increases sharply, resulting in the risk of insufficient power supply. At the ...
