AEM Battery Management System Master - 30-8401M
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.

Since our doors opened in 1987, our goal has been to create innovative new products that set the standard in the performance aftermarket, delivering the highest level of product integrity, and making advanced technologies accessible to the racing masses. We remain true to this mission today. AEM was the first aftermarket company to create a standalone engine management system that plugged into a vehicle’s factory wiring harness, which dramatically simplified the conversion to programmable EFI for racers by mitigating the need for a bespoke wiring harness. We pioneered the Wideband Air/Fuel Ratio Controller Gauge, creating the fastest-responding, most accurate wideband on the market and making this technology affordable for all racers and enthusiasts. We saw a need for better data visualization and logging for racers, so we created the CD Carbon Digital Dash line that will communicate with virtually any CAN-based device regardless of manufacturer, providing racers with the ability to see and log every channel on their vehicle, regardless of where the data is coming from. We don’t rest on our efforts, and we are always looking for ways to provide more horsepower for your dollar. Whether it’s redesigning our wideband technology to make it the fastest responding in the form of our patented X-Series Wideband so you can get the best possible tune, developing new injector technology for our Water/Methanol Injection Systems that provides more efficient cooling while using less fluid, or providing software that is free and fully enabled (no hidden fees), with no cost for updates. We have a deep appreciation for every racer, enthusiast, and distribution partner who chooses to trust our products and always strive to provide an unparalleled customer service experience. We evolve to meet the support needs of our customers and we put our customers first. We will continue to set the standard for service and support in our industry.
