Can_filter

CAN Filter

In Master/Slave system data communication runs on EMUS proprietary CAN communication protocol using a special product for efficient CAN traffic distribution called „CAN Filter“. CAN filter is filtering internal system‘s CAN traffic from external CAN traffic, thus making it stable and reliable.

Control Unit

EMUS G1 Control Unit (or simply Control Unit) is the main controller that autonomously executes all core and utility functions of battery management.

It connects to user’s PC via USB port and allows to make BMS system configuration via EMUS Control Panel.

EMUS G1 Control Unit is also equipped with a non isolated CAN interface. This interface is multipurpose, and enables the Control Unit to:
• Communicate with other CAN equipped EMUS G1 BMS components
• Control certain third-party charging devices
• Transmit BMS activity data (either periodically or by request)
• Receive new configuration parameter values and other special messages

Current Sensor

EMUS support three types of current sensors: busbar dual range, closed loop hall effect and third party “Isabellenhütte” IVT series current sensors.

Cell_group_module

Cell Group Module

CAN Cell Group Modules (also known as CGMs) are advanced, microprocessor equipped cell communication galvanically isolated adapters that allow the Control Unit to communicate with the Cell Modules over the CAN bus instead of directly. Total 32 of them can be used in a single battery pack, which allows to connect the Cell Modules into several small daisy chains instead of one long chain.

Centralized Cell Group Module (CCGM)

EMUS Centralized Cell Group Module (CCGM) is a battery cells communication adapter (or “Slave unit”) equipped with two CAN connectors for easy BMS system assembly and integrated proprietary EMUS software allows data transfer within 100ms frequency. It also have 5 external temperature sensors to monitor ambient temperature.

Each CCGM is capable to manage from 6 up to 16 lithium cells and total 32 CCGM units can be connected in series, parallel or mixed topology. Meaning with one Control Unit client is capable to monitor up to 512 cells battery pack.

EMUS G1 Master-Slave BMS topology is used to build large Lithium-ion battery systems mostly in electric energy storage (EES) applications where high power, capacity, and modularity are required. Such BMS configuration not only allows to build large ESS system, but also provides redundancy features, for example, if one of the battery strings/subsystems runs out of operation, other battery strings can operate and provide power continuously. Up to 6MWh power energy storage systems can be built with off-the-shelf products and larger systems can be made with customized solutions.
EMUS G1 Master-Slave system is a combination of several commonly used EMUS G1 Distributed Grouped or Centralized CCGM subsystems. Simply said, up to 18 strings, with each string having its own G1 Control Unit can be interconnected into one large system. From all of the 18 Control Units, one of them is automatically designated as a „Master CU“ and the remaining Control units as „Slave CU“. In such a way „Master CU“ is gathering information from „Slave CU“ strings and commands operational logic, as well communicates with external devices such as chargers, inverters, VCU, PLC, etc. All system configuration is easily made on EMUS Control Panel, which is provided free of charge to EMUS customers.

This system runs on EMUS proprietary CAN communication protocol using a special item for efficient CAN traffic distribution called „CAN filter“. CAN filter is filtering internal system‘s CAN traffic from external CAN traffic, thus making it stable and reliable.

EMUS G1 Master-Slave system features:
• Wide scalability options for high voltage and capacity systems up to 6MWh*
• Redundancy feature
• Wide passive balancing ranges (400mA, 700mA, 1500mA, 3000mA, 6000mA)
• Operational logic customization with client‘s external devices
• Easy and fast installation
• CAN communication
