Test benches test e-axes of the electric vehicles (EVs).
Main test contents:
Conducted Emission test
Radiated Emission test
Standard: GB/T 18655 & CISPR25
Dynamometer & Mechanical System: There are two dynamometer units, each unit can be move in or out the anechoic chamber. The tested e-axes is mounted on the plate, and connect to the dynamometer units by CV shaft.
Battery Simulator or Bidirectional DC Power Supply: Simulates an on-board battery pack to supply power to the inverter and the motor. The DC power connects to HV filter outside the anechoic chamber, and then connect to HV AN by HV lines.
MCU Power Supply: Provides a low-voltage power supply for the motor controller. Customer can also select the battery which put on the test table.
Test Object Cooling System: Supplies cooling medium for the tested E-axle and E-drive. An oil or water-cooling system is available for certain oil-cooled or water-cooled test pieces. Parameters including temperature, pressure and flow rate of the cooling system are fully adjustable. The water-cooling system can also use ethylene glycol as the cooling medium. The cooling system is connected to the fluid waveguides mounted on the wall of the anechoic chamber.
Automated Measurement & Control System: Conducts overall control and condition monitoring of the entire motor test bench.
