Mobile energy storage system and control method

Abstract

The invention discloses a mobile energy storage system and a control method, and aims to solve the problems about the starting power supply and starting control of a mobile energy storage system and the problems of low reliability and low cruising ability when a UPS (Uninterrupted Power Supply) is adopted as a starting power supply of a mobile energy storage system in the prior art. The mobile energy storage system comprises a self-release button S1, a direct-current contactor KM1, a direct-current contactor KA1, an alternating-current contactor KM2, an AC/DC switching power supply, a DC/DC switching power supply, a diode D1, a diode D2, a battery, a BMS (Battery Management System), a PCS energy storage converter and a DSP controller. According to the invention, the button and the contactors are matched with a software algorithm to replace the traditional UPS, and the integration cost of the mobile energy storage system can be reduced under the condition of improving the space utilization rate. Starting control is carried out for a grid-connected mode and an off-grid mode, starting control and redundant power supply of the mobile energy storage system under various conditions can be guaranteed, and the reliability of the system can be improved.

Description

technical field [0001] The invention relates to a mobile energy storage system and a control method, belonging to the technical field of energy storage equipment. Background technique [0002] With the rapid development of modern society, society's dependence on electric energy is also increasing, and mobile energy storage systems have also emerged as the times require. As one of the main forces of emergency power supply equipment for urban power grids, compared with traditional diesel generators, mobile energy storage systems have many advantages such as flexible maneuverability, mature technology, quick start, energy saving and emission reduction, etc. It is playing an increasingly significant role in small and medium-sized power consumption places such as emergency response, combating major natural disasters and temporary power consumption. With the implementation of our energy saving and emission reduction strategy and the advancement of new energy power generation tech...
