E-PROPULSION TEST SYSTEM MODEL 1210 MODEL 1210
Chroma

Chroma introduces the Chroma 1210 E-Propulsion Test System, designed for both passenger and commercial electric vehicle (EV) applications. This system provides comprehensive simulation and testing for EV powertrains, including e-motors, motor drivers, transmissions, and e-drive systems.

The Chroma 1210 is primarily used for performance calibration and verification of automotive powertrains. It offers the capability to integrate whole-vehicle dynamic models for simulating and validating mechanical components. The system supports both manual and programmed operation, with synchronized recording of critical physical parameters such as voltage, current, power, speed, torque, and temperature.

During testing, generated power is fed back to the grid via Chroma's regenerative bidirectional DC power supplies (17040 and 62000D series). The 1210 also features battery simulation, allowing real-time emulation of battery response characteristics during vehicle operation for highly reliable verification. The E-Propulsion Test System has 4-quadrant operation capability, maintaining constant torque loading below rated speed (including zero speed and reverse), and constant power loading above rated speed.

The test bench employs an integrated mechanical design, using modal analysis to simulate stress and resonance. It supports full-speed range testing and features a modular clamping system that accommodates a variety of motors under test. Comprehensive safety mechanisms include overcurrent, overvoltage, undervoltage, and short-circuit protections, as well as power phase-loss detection, temperature monitoring, and overload response warnings. The complementary E-Propulsion Test software features DBC file loading, manual control, and data monitoring. The testing interface supports real-time waveform display, showing 2D graphs of speed, voltage, current, and other values against time, with configurable data sampling rates. The 1210 system can run preset operating conditions. By importing CSV files, users can define test voltage values, current protection values, motor (load side) speed commands, motor (DUT) torque commands, and other control parameters corresponding to time conditions.

Test reports include customizable charts, generating information such as product name, test date, and test parameters. For user-selected test data, the system can produce time-based parameter curves and efficiency maps for motors and motor drivers. Built on an open software architecture, the Chroma 1210 seamlessly integrates with existing lab equipment and safety monitoring systems. Its built-in vibration monitoring ensures comprehensive oversight of both the test bench and device under test, making it an ideal solution for modern testing facilities seeking to streamline their operations through unified laboratory integration and management.
