AEM Battery Management System Mini Master
The BMS is implemented as two different Module types: the BMS Mini Master and the BMS Satellite. Each Module is capable of measuring up to 18 cells and 3 temperatures (thermistors) but the 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 Mini Master Module and all battery packs need at least one Mini 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.
Features:
- Add-on expansion for VCU products, enabling the VCU’s battery management features
- Distributed BMS architecture allows for easy support of distributed battery packs
- Interfaces with J1772 Charge Port to automatically power up vehicle when charge plug is connected
- Up to 16 BMS18 Satellites can be connected to a single BMS18 Mini Master to support up to 1200V systems
- Communicates with Satellites via a high-speed isolated serial interface (isoSPI)
The AEMEV Mini Battery Management System is comprised of three components:
1. VCU
2. BMS-18 Mini Master
3. BMS-18 Satellite(s)
