The PCS is an essential component of an energy storage system. The following
diagram gives an example of how it works with other components in such a system.
The PCS is bidirectional power conversion system. It can charge or discharge energy
to/from batteries.
The BMS (Battery Management System) in a battery container is used to intelligently
manage and maintain each battery module and rack, prevent the battery from
overcharging and discharging. It can extend the life of batteries, monitor the batteries
status.
The EMS (Energy Management System) is power grid dispatching automation
system (including hardware and software). It is used for data collection, energy
management, and network analysis.
The EMS sends commands to the PCS to monitor the status of the PCS and BMS.
The PCS can charge or discharge the batteries. The EMS communicates with PCS
by RS485/RTU or Ethernet. The PCS communicates with BMS via CAN port.
