Turnkey Test Systems for Electric Vehicle (EV) Drivelines and Components

Project Type: Electric Vehicle Design Validation, Performance, Durability and Quality Control Testing

Customer: Tesla Motors, UQM Technologies, Magna Electronics, and others

Dynamometer: AccuDyne AC Motoring Dynamometers

Control System: DynoLAB

Other Equipment: High Voltage Battery Simulator

The complete turnkey testing system for Electric Vehicles (EV’s) can be configured to automate all types of design validation, performance, durability and quality control testing, including complex in-use and road load simulations for both drivetrain components and electric motors and drives. The testing system has been used extensively by major EV manufacturers, including Tesla Motors, UQM Technologies and Magna Electronics. AccuDyne dynamometers offer full 4-quadrant operation with seamless transition between loading and motoring modes. The high voltage DC battery simulator provides reliable, repeatable power independent of battery charge state. Since the AccuDyne and battery simulator are both fully line-regenerative, the resulting system can recapture most absorbed power, making it extremely energy-efficient. The system can also test high-voltage batteries typically used in EVs. Testing may include standard charge-discharge cycles, as well as road-load profiles representative of what the battery would see in an actual vehicle under real-world road conditions.
