Power sharing system for charging and exchanging power station and control method thereof

Abstract

The invention discloses a power sharing system for a charging and replacing power station and a control method thereof. The system comprises a charger, a plurality of replacing battery packs, a plurality of charging columns and a monitoring device. The charger comprises a plurality of AC / DC charging modules, wherein the plurality of AC / DC charging modules are respectively connected with the battery packs through a plurality of contactors one-to-one; and each AC / DC charging module is respectively connected with all charging columns through a plurality of contactors for supervising and collecting the information of the power exchange battery packs and the charging columns, sending a charging instruction to each AC / DC charging module, and sending a power switching instruction to the switchingcontrol unit, so as to toggle the state of the corresponding contactor. The power sharing system for a charging and replacing power station realizes the intelligent distribution of power and extractsthe state of the switching control unit, solves the problems of idle power at night of the exchange station and high idle rate of the charging station in the daytime, and solves the problem of charging multiple vehicles simultaneously. When charging is guaranteed, effective power distribution is carried out among the charging columns to realize the efficient utilization of resources.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to a power sharing system and a control method for a charging and swapping station. Background technique [0002] With the popularity of electric vehicles, the public's demand for charging is also increasing. Therefore, the construction of charging facilities has become extremely important. The construction of charging facilities is divided into charging stations and swapping stations. The main working hours of the charging facilities of the charging station are mostly concentrated at night, and the idle rate is high during the day; the main working time of the swap station is concentrated in the daytime, and the working hours of the charging facilities of the swap station are mainly concentrated in the daytime and idle at night. [0003] The current swap stations on the market are unrelated to the charging facilities of the charging station. The charging facilities of th...

AI Technical Summary

Problems solved by technology

The charging facilities of the swap station have no power output at night, and the charging facilities of the charging station have no power output or output at a lower power during the day. The separate construction will require higher costs and occupy a large amount of space, resulting in a waste of resources
