EMUS BMS Integration cases

Applications range from electric vehicles, industrial applications to energy storage.

Case examples with EMUS BMS supplied to OEMs

  • One of the latest and complex EMUS project’s started in 2020. It is an integration of high voltage BMS system for the electric bus (2x55kWh battery packs) for the Asian fully electric bus manufacturer (OEM). Tier 1 supplier demanded custom made battery management system which has automotive grade components, expandable CAN bus line architecture, fast charging functionality using two chargers, each for
    separate battery pack. Parties involved into the project acknowledged EMUS proprietary SOC calculation algorithms based on Open Circuit Voltage model (OCV) as a leading industry standards, providing highest accuracy and reliability.
    It was challenging to make integration support during COVID-19 pandemic with travelling restrictions, however EMUS engineering team managed to make all support using online communication tools.
    EMUS customers can be sure, that they’ll be provided with the highest quality BMS systems, designed using latest technologies and components, as well get full support during integration ant testing phase!

 

  • In 2021 EMUS is proud to be involved as a Tier 2 battery management systems provider for the South Korean special equipped vehicle manufacturer to build Li-Ion cells powered refrigerating containers for the food delivery trucks.
    Tier 1 supplier requested for a reliable BMS system with CAN communication, which can support minimum battery pack’s charging ranges from 150V up to 250V. With EMUS Centralized CCGM system implemented, battery pack has flexibility to be charged by all main charging stations in the country and abroad.
    EMUS developed proprietary SOC/SOH advanced algorithms based on current and voltage counting, early warnings and protections software allow safe, efficient battery cells operation and low maintenance cost.

 

  • Company from Norway (est. in 2012) is a manufacturer of light electric vehicle that uses EMUS BMS. It was designed specifically for delivery service. With the range of a full charge, it can keep going for 4-10 hours, or 40-100 km, depending on the battery capacity, enough to complete most delivery routes without recharging.

For energy storage

Numerous companies have successfully used Emus BMS to develop industrial and domestic solar or wind energy storage systems,  using hybrid  inverters. The main advantages and benefits for clients using EMUS BMS are listed below:

  1.  CCL (Charging Current Limit) management depends on maximum/average individual cells voltages estimated values. EMUS BMS controls charging power limits by monitoring and estimating maximum and average battery cells’ “charging left” estimations.
  2.  CVL (Charging Voltage Limit) hysteresis (new value estimation dependency on previously received data) for requested charge voltage stabilization at the end of the charging cycle. Increase charging speed and ensure safe battery charging without cell voltage overshoots.
  3.  CCL (Charging Current Limit) management algorithm depending on cell disbalance. BMS Controls charging power limit by monitoring and estimating cell disbalance. It helps to have at the end of the charging cycle fully balanced battery cells.
  4.  Balancing on discharge functionality. Decreases the battery cells balancing time. Functionality perfectly fits using inverter-based battery installations.
  5.  Requested charging power stabilization using BMS measurements hysteresis. The functionality reduces the number of unnecessary power change requests and stabilizes the requested power limit.
