Explanation of Professional Terms

1.Energy Storage: refers to the media or equipment to store energy, and then release the process when needed, usually energy storage mainly refers to the power energy storage.

2.PCS：Power Conversion System (PCS) can control the charging and discharging process of the battery, carry out AC/DC conversion, and directly supply power to AC loads in the absence of power grid. PCS consists of DC/AC bi-directional converter, control unit, etc. PCS controller receives the back-end control instructions through communication, and controls the converter to charge or discharge the battery according to the symbols and sizes of the power instructions to achieve the regulation of active and reactive power of the power grid. The PCS controller receives background control instructions through communication and controls the converter to charge or discharge the battery according to the sign and size of the power instruction, so as to achieve the regulation of active and reactive power of the power grid, and the PCS controller communicates with the BMS through the CAN interface to obtain the status information of the battery pack, so as to realise the protective charging and discharging of the battery, and to ensure the safe operation of the battery.

3.BMS: Battery Management System, a BMS battery management system unit comprising a BMS battery management system, a control module, a display module, a wireless communication module, an electrical device, a battery pack for powering the electrical device, and a collection module for collecting battery information from the battery pack. BMS battery management system connected to the wireless communication module and the display module via communication interfaces. BMS battery management system is connected to the wireless communication module and the display module respectively through a communication interface, the output of acquisition module is connected to the input of the BMS battery management system, the output of  BMS battery management system is connected to the input of the control module, which is connected to the battery pack and the electrical equipment respectively, and BMS battery management system is connected to a server side of the Server through a wireless communication module.

4.EMS: Energy Management System, main function by the basic function and application function of two parts. Basic functions include: computer, operating system and EMS support system.
