The PRS-7921 Orderly charging management terminal is a device developed by CYG SUNRI for orderly charging management. Due to the expansion of charging businesses, and the domestic distribution network is under the pressure of high and heavy loads to support new energy vehicles, related policy requires gradual development of new energy vehicles in China, which will increase the power consumption of power distribution networks and communities. The terminal aims to effectively guide charging users to access the charging load, alleviate the load on the distribution network, adjust the charging strategy of users and optimize the charging cost.

The PRS-7921 Orderly charging management terminal intends to establish an orderly charging operation and management platform for electric vehicles. According to the predicted load curve of entire network, load curve of clean energy, electric vehicle charging demand and local capacity limit of the distribution network, the orderly charging strategy is designed. Real-time monitoring of the main network, distribution network, and clean energy load is carried out, decision about the charging time sequence that should be executed by electric vehicles currently connected to the network is made, and instructions are sent to the corresponding charging equipment to complete orderly charging management.If there is a local distribution network capacity limit that cannot meet the charging requirements of all vehicles within their specified time periods, it is necessary to introduce an interruptible load electricity price mechanism to reduce its power supply or adjust to other time periods to meet the charging demand.
