2.1.1 Battery Module (Type A / Type B)
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.
There are two types of 8S1P Battery Module depending on the position of terminal’s polarity.
Type A’s plus(+) terminal is on the right side. Type B is on the left.
Type A: EM2031AE00XA (X = 1, 3)
X = 1 for specific customer (customer SKU serial number barcode + SDI serial number barcode)
X = 3 for general customer (SDI serial number barcode only)
Type B: EM2031AE00YA (Y = 2, 4)
Y = 2 for specific customer (customer SKU serial number barcode + SDI serial number barcode)
Y = 4 for general customer (SDI serial number barcode only)
