EmusBMS
All-in-one BMS system for up to 16 cells.

The EMUS Mini 3 BMS is a compact, all-in-one Battery Management System designed to autonomously manage and execute all the core and utility functions of battery management. It features built-in contactors for charging and discharging circuits, monitors cell voltage, adjusts charging and balancing, and interfaces with system components via versatile inputs, outputs, and communication interfaces.
Capable of managing battery packs with 6 to 16 series-connected cells, it ensures safe, efficient, and reliable operation, making it ideal for a wide range of applications.

Features:

  • Sleep Mode: Minimizes power consumption during idle periods, conserving energy and extending the battery pack’s operational life
  • Short-Circuit Protection: Ensures system safety by detecting and mitigating short-circuit events, preventing damage to the
    battery pack and connected components
  • SD Card Logging: Stores all log data, allowing recovery and analysis of unexpected events to support diagnostics and
    performance tracking
  • Comprehensive Monitoring: Monitors 6 to 16 cells per BMS unit, ensuring precise control and safety of the battery pack.
  • State of Charge (SOC) and State of Health (SOH) Algorithms: Advanced algorithms track cell degradation and calculate
    SOC based on real capacity and internal cell parameters, enhancing the accuracy and longevity of the battery system.
  • Battery current measurement
  • Balancing of the cells
  • Protections and warnings adjustable on the Control Panel
  • Integrated contactor to protect the battery
  • Integrated pre-charge circuit to allow soft start of motor controllers
  • Connectivity to various types of chargers
  • USB Interface: Easy, fast and simple connection to a host device, such as a computer, tablet, or smartphone, for
    configuration, diagnostics, and maintenance
  • CAN Data Interface: Facilitates smooth communication with CAN-enabled EMUS devices and third-party systems, allowing
    for integration into various configurations
  • Bluetooth Interface: Allows wireless real-time data transmission to the EMUS EVGUI app, providing instant access to key
    information
  • Flexible CAN Baud Rates: Supports a range of CAN Baud rates, including 50, 125, 250, 500, 800 kbit/s, and 1 Mbit/s, with
    a default of 250 kbit/s, ensuring adaptability to different systems
