SAKOR Technologies, testing company, has introduced a complete testing system for hybrid and electric vehicles. The system features AccuDyne AC motoring dynamometers, a high voltage DC battery simulator, and a DynoLAB PT data acquisition and control system. The complete turnkey testing system can be configured to automate 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 HEV 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 that is independent of battery charge state. Since the AccuDyne and battery simulator are both fully line-regenerative, the resulting system can recapture most absorbed power and is therefore extremely energy efficient. This reduces overall system operating costs. The system is fully automated by SAKOR’s DynoLAB PT control system, which offers complete automation of all types of test cycles used in performance, durability, and quality control testing.
The system can also test high-voltage batteries typically used in HEVs. The testing can 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.
