AEM Electronics Battery Management System Master - BMS Master Module for VCU

The AEM Battery Management System (BMS-18) is comprised of three components: | 1. VCU | 2. BMS-18 Master | 3. BMS-18 Satellite(s) | 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 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 VCU is responsible for all BMS control logic. All setup and calibration items can be modified using the AEMCal user interface.
