Automotive Grade 2 DESCRIPTION The JTT S-Series Battery Management System (BMS) controllers are stand-alone Low Voltage Battery Control Systems. This all in one, single BMS controller can monitor battery packs up to 48 cells and 200V. The S-Series controllers come in 4 different models: S1, S2, S3, and S4. The S1 can monitor 12 cells, S2 can monitor 24 cells, the S3 can monitor 36 cells, and the S4 can monitor 48 cells. Each bank of 12 cells monitors 12 cell voltages and 12 temperatures. The S-Series balances the voltage and charge between all cells the battery pack by passive balancing. Energy is discharged from the highest charged cells in the pack, and thus maximizes the range of a battery pack and extends its life. The cell balancing is based on the amount of charge in each cell and not the cell voltage, and so balancing is active continuously during operation and not just during idle periods. An intelligent software system runs more than 80 diagnostics at faster than 10 times a second, on both the cells and the entire battery pack. Most diagnostics are to ensure safe operation of the battery pack, and the rest are for monitoring batter
