EMUS G1 BMS for Builders and Integrators

Configurable Control for Builders and Integrators

Battery management is one of the most critical yet overlooked parts of an EV or storage project. Without a reliable BMS, even the best lithium pack can become unsafe or underperform. That’s where EMUS comes in.

The EMUS G1 Centralized Battery Management System is a modular platform designed to give builders, from DIY converters to ESS engineers, professional-grade control over their packs. At its core, the system combines a master control unit with multiple Cell Group Modules (CCGMs) that directly connect to your cells. This centralized approach keeps wiring simple while scaling to hundreds or even thousands of cells when needed.

In a typical light EV build, one control unit is all that’s required. It handles CAN communications, safety logic, I/O mapping, and data logging. Each CCGM supports 6 to 16 series cells with integrated passive balancing and temperature monitoring. Up to 32 CCGMs can be daisy-chained under a single control unit, giving that controller oversight of as many as 512 cells. For larger applications, up to 12 control units can be linked together, supporting a maximum system size of 6,144 cells—all using the same architecture.

Flexibility is where EMUS shines. Current sensors come in several formats: a dual-range bus bar style for high accuracy, a loop-through clamp for rugged mobile use, and a CAN-enabled bus bar option that integrates directly with the control unit. Plug-and-play harnesses, CAN hubs, and optional add-ons like digital displays and remote monitoring simplify integration.

Just as important as the hardware is the software. The EMUS control panel is free to use, giving you real-time insight into state of charge, balancing behavior, and protective responses during charge and discharge cycles. Builders can configure I/O functions, track data over USB or RS232, and integrate with chargers, inverters, and vehicle controllers over CAN.

For those stepping into EV conversions or scaling up to commercial energy storage, the EMUS G1 platform provides a professional-grade toolset with short lead times and responsive support.
