For electric vehicles

electric vehicle

Light electric vehicles

The Paxster (Norway, est. in 2012) is the first mass produced electric vehicle that uses EMUS BMS. It was designed specifically for post delivery services, and is used by the National Norway Post. 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.

Heavy duty electric vehicles

The battery pack inside of GINAF (Netherlands) E-Series Duratruck consists of 188 200Ah Lithium cells that are distributed over 2 packages, and are managed by EMUS BMS. The total capacity varies between 100 and 180 kWh, good for an action radius between 100 and 150km.

For energy storage

storage

Numerous companies have successfully used Emus BMS to developed industrial and domestic solar or wind energy storage systems, such as Enerwit (Germany), who have helped us to integrate support for SMA Sunny Island inverters into Emus BMS.

Application Examples

The most flexible BMS in the world

Our flexible distributed-hybrid topology BMS G1 architecture that was introduced in 2010 lets our customers assemble the system for virtually any battery application. It has been used by many satisfied customers around the world for years in electric vehicles, maritime, home and industrial energy storages and many other applications. We continue improving and expanding it every day. In Spring of 2018 We introduced brand new BMS “MINI”, which is integrated centralized topology BMS ideal for small devices applications that have up to 16 small/medium capacity cells. Still in 2018 we’ll release new generation 3 set of BMS components with further enhanced characteristics and functionalities. Centralized active balancing BMS is planned to be released by end of 2018.

Key Features of EMUS BMS

  • Remote Monitoring solutions via Wi-Fi/Cellular visible on online portal
  • Supporting PC, Android and iOS software for maintenance and monitoring
  • Easy to install and maintain

Application Configurations

Application of EMUS BMS MINI

app-mini

BMS MINI was designed to make it very simple to install and configure. As it has all required BMS functional blocks integrated it does not need any external components to make your Lithium cells into a fully functional battery pack of up to 16 cells and currents up to 75 Amperes. Yet due to its integrated LIN and CAN interfaces it can be enhanced into a system capable of handling much higher currents.

As it has integrated low energy Bluetooth it is intended to be configured and monitored from Android or iOS device.

Application of EMUS BMS G1 system

app-g1-system

Single pack simple application scenario

BMS controls one package of Lithium cells connected in series ranging from 1 to 255 Lithium cells with capacities from few up to thousands of Amp-hours each. The whole package is controlled by Control Unit which has interface to Cell Modules that are directly mounted on Lithium chemistry battery cells. Each Cell Module measures cell’s voltage and temperature and returns this information back to Control Unit via communication wire. The Cell Modules are interconnected with a single communication wire running from module to module. The first Cell Module (at the “” terminal of the pack) and last Cell Module (at the “+” of the pack) are connected to Control Unit via optical Top/Bottom Isolators which perform data interface adaption and ensure Control Unit circuit isolation from high voltages of the battery pack. Current Sensor is inserted in battery’s power line and is connected to Control Unit for charging and discharging over-current protection as well as measuring transferred charge for SOC/ SOH evaluations.

Split groups application scenario

split-groups-scenario

In many applications the whole battery needs to be split into separate blocks or groups of cells that might be placed in different locations of vehicle or other device. Packs may be needed to be connected in series and/or parallel configurations to achieve needed battery characteristics.

In such cases EMUS BMS can be configured to use CAN Cell Group Modules instead of Top/Bottom Isolators and communication to each group performed separately via robust CAN bus link. Control Unit supports up to 32 CAN Cell Group Modules. Each CAN Cell Group Module can process up to 255 Cell Modules thus allowing whole EMUS BMS to handle up to 8160 cells.

A Display Unit may be connected to Control Unit in this or any other configuration scenario to indicate the kay battery parameters to operator or driver of vehicle.

Master / slave redundancy / Hot – swap application scenario

hot-swap-scenario

For applications requiring modularity, redundancy or hot-swap capability several EMUS BMS systems can be combined using Master/Slave of Control Unit. Many applications the whole battery needs to be split into separate blocks or battery modules that might be placed in different locations of vehicle or other device. Battery pack modules may be connected in series and/or parallel configurations to achieve needed battery characteristics.

Special model of EMUS BMS Master/Slave Control Unit with special firmware can be configured in Master / Slave configuration. The Cell Modules in each battery module may be connected to each Master/Slave Control Unit using Top/Bottom Isolators or CAN Cell Group Modules. When operating the Control Units firmware is automatically selecting the Master unit which takes care of communicating to central charger and controlling the charger process.
