Benefits
EVolution is an open extensible real-time deterministic platform for electric vehicle battery test cell control and data acquisition. Ready to deploy off-the-shelf the software offers a number of key benefits:
- Low-cost entry-level.
- Quick and easy to deploy, configure and replicate.
- Faster development times with automation and collaboration.
- An open platform for greater modularity, flexibility, model integration and custom sensors.
- Complete test coverage achieved with a flexible platform for accurate and innovative test systems.
- Straightforward integration with existing systems.
- Adaptable to rapidly accommodate changing/future requirements, therefore, reducing costs and complexity.
- Proven expertise in this field.
Powerful Features
Based on the NI platform the software is designed to offer maximum flexibility and extensibility to integrate across any hardware configuration, and with a deterministic real-time test engine at its heart, the system can run high-speed models and close the loop with real sensor data at rates upwards of 1 kHz. The advanced software is designed to address many of the issues faced by a busy and technically demanding test environment including powerful features to support efficient test configuration and deployment:
- Intuitive user-friendly interface and workflows.
- The ability for high-speed synchronous data acquisition and logging (up to 200kHz – requires specific hardware options/support).
- Standard 1kHz loop rate for model execution, IO update rates and data logging.
- Flexible to support multiple model formats including MATLAB/Simulink, AVL Boost and Cruise, TechnaliaDynaCar, IPG CarMaker, LabVIEW, etc. Simply import new models as compiled DLL and map inputs and outputs.
- Simple and fast to deploy standard scripts or create new scripts via Python scripting tool and support library or real-time sequence wizard.
- Supports long continuous test durations with a built-in real-time sequencer (when based on headless real-time system).
- Change and manage test cell configurations from a single interface.
- User level-based access.
- A dynamic user interface that can be reconfigured in tests removing the need to restart.
- Open extensible architecture. Add new sensors or bespoke protocols via a simple low-cost, ‘plug-in’ upgrade or import via the built-in template. The new custom device is automatically verified, packaged and deployed down to the real-time controller.
- Apply application-specific safety protection models.
- Wide range of standard comms buses are supported such as High Speed CAN bus up to 1 Mbits/sec, Ethernet up to 1000BASE-T, Generic RS-232, EtherCAT, CANopen, Profibus, FlexRay, LIN (please note that many of these require specific interface cards).
The software includes a number of battery test specific features:
- Specific battery protection models and fixed device definitions applicable to battery testing
- Application-specific user interface widgets
- Device plugin in for Unico EtherCAT Battery Cycler*
- A generic Battery plugin device with a wizard-based UI to reduce the time required to add a CAN-based Battery pack/BMS to the system.
- Environmental Chamber plugin device – currently supports ACS Chambers*
- DUT Chiller Plugin Device – currently supports Huber* or Lauda*
- Generic Python Scripts for the following standard battery tests
- DC-IR
- Capacity
- Max Power
- Endurance Cycle – Playback of a CSV file.
*Plugins proven on specific device models and may require specific communication interface cards.
