Mustang Dynamometer Upgrades Dyno at AEM Performance Electronics for EV Testing

Jul 2, 2021

Mustang Dynamometer, an American manufacturer of dynamometers and related products, has completed an upgrade of an existing dynamometer at AEM Performance Electronics in Hawthorne, California.

The MD-1750 large roll chassis dynamometer was originally installed in 2001. Although pleased with the installed equipment, AEM has shifted into the research and development of the performance EV market segment. Electric Vehicle drivetrains output big torque at low RPM creating a need for more steady-state loading capability, the company said. AEM contacted Mustang Dynamometer about adding a second power absorber unit (PAU) to the dyno and upgrading both new hardware and software of the controls system.

The MD-1750 model dyno has a set of 50-inch rollers and is designed for testing large and very high horsepower vehicles without concern for tire slippage, the company said. A pair of 50-inch diameter rollers act as the road-load mechanism which provides inertia-based performance testing at various speed and torque outputs. It has a maximum speed of 250 mph and a horsepower measurement rating of 3,500 horsepower. A major part of the upgrade is new software and hardware to the controls and data acquisition systems.
