2. Product Description

The Battery system consists of four major components: 67Ah 8S1P Battery Module (“Battery Module” hereinafter), String Management Unit (SMU) and SMPS Assembly. A single rack configuration of 34.6kWh Battery System is comprised of one SMU and one SMPS Assembly and 17 Battery Modules.

Battery Module is the most basic component of the Battery System and it contains the energy storing battery cells. There is a Module BMS inside each Battery Module. Module BMS checks the status of a Battery Module by measuring its voltage and temperature. It also communicates with the SMU to send all measured voltage and temperature data, and to receive commands to control cell balancing.

SMU collects all information about the battery system and controls the battery system by switching the main power line and controls each Battery Module by cell balancing. SMU calculates the state-of-charge (SOC) and state-of-health (SOH) of the battery system. Key components in the SMU are Rack BMS, MCCB, and shunt resistor. Rack BMS is the main controller that takes all data from the Module BMS, measures the string voltage and current, determines the state of the battery and controls the MCCB accordingly.

SMPS Assembly Type A is comprised of System BMS and switching mode power supply (SMPS). SMPS Assembly Type A supplies power to the BMS and communicates with Uninterruptible Power Supply (UPS). SMPS Assembly Type B is comprised of only SMPS which supplies power to the BMS.
