The manual introduces the features and characteristics of Orion BMS 2 products.
This manual provides detailed instructions for setting up, wiring, and operating the Orion 2 BMS by Ewert Energy Systems. It covers how the BMS monitors cell voltages, current, and temperature to manage battery packs in electric and hybrid vehicles. The manual includes sections on configuring settings via software, testing the system, and understanding diagnostic features. It also explains how the BMS controls charging and discharging through CANBUS or analog outputs, and how it interfaces with J1772 and CHAdeMO chargers.
The Orion 2 BMS features improved cell voltage accuracy (0.1mV resolution), compatibility with 12V and 24V power supplies, and expanded diagnostic capabilities. It supports up to 8 thermistor inputs and can be configured for multi-unit operation with remote modules. The manual emphasizes user responsibility for verifying correct operation and ensuring safety during testing.
| Cell Voltage Measurement Accuracy | 0.1mV resolution |
|---|---|
| Thermistor Inputs | Up to 8 thermistor inputs directly on the BMS |
| Power Supply Compatibility | Compatible with both 12-volt and 24-volt power supplies |
| Current Sensor Measurement | Measures current every 8mS using external hall effect sensor |
| Cell Voltage Measurement Interval | Approximately every 30 mS |
The BMS calculates current limits based on cell voltages, temperatures, amperage, and programmed battery pack profile values.
It supports J1772 and CHAdeMO charging interfaces for AC and DC charging.
It has up to 8 thermistor inputs directly on the BMS, with additional inputs available via expansion modules.
The BMS must be programmed using the Orion BMS 2 Utility software and a CANdapter (CAN to USB adapter) before use.
