The invention provides an energy storage system for a bus charging station. The energy storage system comprises a battery unit for providing backup output power, a battery management system connected with the battery unit, a grid-connected converter which is connected with the battery unit and the battery management system, is connected with the bus charging station and is used for realizing current regulation of the energy storage system and a charging station power grid, and an energy management unit which is connected with the battery management system and the grid-connected converter and is used for receiving a power grid current signal of the charging station and at least one charger signal and controlling whether the grid-connected converter is connected or not according to the power grid current signal and the charger signal, so that electric energy is provided for the charging station through the battery unit, or electric energy is provided for the battery unit through the charging station power grid. The energy storage system provided by the invention can solve the problem of insufficient power when a plurality of new energy buses are charged, and can be used as a backup power supply to continuously provide charging service for the new energy buses when the charging station power grid is overhauled or breaks down.
Description
technical field [0001] The application belongs to the field of electric power technology, and in particular relates to an energy storage system for a bus charging station. Background technique [0002] With the rapid popularization of new energy buses, more and more bus stations have adopted new energy buses. Correspondingly, bus stations are also equipped with bus charging stations. However, new energy buses are equivalent to new energy cars, and their power is greater. When multiple buses in the bus charging station are charging at the same time, the demand for electric energy is very large, resulting in insufficient capacity actually allocated to the bus charging station in the power grid. Contents of the invention [0003] The purpose of this application is to provide an energy storage system for a bus charging station, so as to solve the problem of insufficient electric energy of the bus charging station pointed out in the background art. [0004] The technical solu...
