Thunderstruck BMS satellites are connected to a BMS controller via daisy-chain communication networks (isoSPI). Multiple satellites allow monitoring a large number of cells in a pack, with various cell configurations. A BMS Satellite cannot operate without a controller.
24-cell satellites contain 2 groups of 12 cells - each with an LTC measurement device. The 18-cell satellite has a single LTC device for 18 cells. A minimum of 4 cells must be connected to any single LTC device. A wide variety of pack layouts and cell counts can be accommodated with satellites.
Examples of BMS controllers from Thunderstruck are the BMSC (BMS Controller) and the MCU (Master Control Unit).
- The BMS Controller manages 24 cells alone, and wth 24-cell satellites added, can support up to 96 cells.
- The MCU does not manage cells alone, but connects to either 24-cell or 18-cell satellites to manage as many as 288 cells in a pack.
BMS Harness Tester
- Required for testing BMSS cell harnesses before final connection (smoke prevention)
