Cell Communication adapters are a required part of the EMUS BMS. Depending on your pack configuration, choose between Optical Isolators for single-segment battery packs or CAN Cell Group Modules for larger more complex multi-segment battery packs. Only one Top/Bottom set of Optical Isolators is needed for single segment packs; however, multi-segmented packs will require one CAN Cell Group Module per segment.
Optical Isolators
Recommended for use in consumer applications and small, single-segment battery packs. Typically used when battery banks are separated by less than 1 meter.
EMUS BMS Top/Bottom Isolators are cell communication adapters that provide optical isolation in application where the main controller communicates directly to EMUS BMS Cell Modules. The Bottom isolator connects between the main controller and the first cell of series-connected battery pack, while the Top Isolator provides isolating barrier between the last cell of series-connected battery pick and the main controller.
Recent developments in rechargeable battery technology allow wider use of electric propulsion in electric vehicles, electric motorcycles, boats etc. Most popular high performance batteries are based on Lithium chemistries. Such batteries require systems to keep them in the specified usage range while being used. A Battery Management System (BMS) is required for batteries that are sensitive to their usage conditions such as current, voltage and temperature. The Emus BMS is the product intended for use with LiIon, LiPO, LiFePO4 and other chemistries prismatic battery cells which operate in voltages ranging from 2V to 5V. The Emus BMS is a distributed type of digital BMS with a central Control Unit. It does the balancing of the cells by dissipating the excess energy of cells as heat which is often referred to as passive balancing.

CCCGM (Centralized Can Cell Group Modules)
EMUS Centralized CAN Cell Group Module (also known as CCGM) is advanced cell communication adapter for interfacing main controller and a battery pack up to 16 lithium cells which enables Emus battery management system to save space by reducing the need of having cell modules as each CCGM directly monitors each battery cell. Up to 32 Centralized CAN Cell Group can be connected to the system.
Each Centralized CAN Cell Group Module includes:
1x Centralized CAN Cell Group Module
1x Quick Start Wiring Kit
Cell Modules
Each battery cell will require one cell module. So, if you intend to order a 24V DC battery pack (8 battery cells, or 2x4-cell packs), enter a quantity of 8. If you intend to order a 48V battery pack (16 battery cells, or 4x4-cell packs), enter a quantity of 16, and so on...
