The VCU communicates with the BMS via the Master Module and all battery packs need at least one Master unit. The Satellites expand the capability of the Master by an additional 18 cells and 3 thermistors per additional Satellite connected. The Satellite Modules are connected to their Master via a high-speed serial interface (isoSPI) that allows additional units to be daisy chained together, adding as many Satellites as necessary for the battery pack configuration.
The BMS is implemented as two different Module types: the BMS Master and the BMS Satellite. Master also contains the CAN communication interface and J1772 charging specific connections needed for each battery pack.
The VCU is responsible for all BMS control logic. All setup and calibration items can be modified using the AEMCal user interface.
AEM Battery Management System Master (MUST BE USED WITH AEM VCU - 18 Cell Taps)
The AEM Battery Management System (BMS-18) is comprised of three components:
· Contains J1772 charging specific connections needed for each battery pack
· Contains the CAN communication interface needed for each battery pack
· Capable of measuring up to 18 cells and 3 temperatures (thermistors)
· Can be daisy chained to multiple satellite units
· Weatherproof connector and housing
