8 Things to Consider When Choosing a Chassis Dynamometer for Electrified Vehicle Testing


When investing in a chassis dynamometer for your vehicle test facility, it is important to make a decision with the long term in mind. As technologies and regulations change, your test environment must remain as flexible and efficient as possible. Choices made today need to meet both current testing needs and prepare your organization for a changing mobility market.

To that end, the tools in today’s test cell must be multi-use, without compromising the performance aspects required from evolving vehicle technologies. Choosing a chassis dynamometer with permanent magnet (PM) AWD technology expands your test capabilities with aspects such as exceptional power per wheel (more torque available at higher wheel speed) and torque vectoring capabilities. Cost effectiveness is also an important consideration.

PM dynamometers offer superior road load simulation for vehicle launch events (which has significant contribution to emissions) and vehicle launch calibration. They also consume as much as 15% less energy than alternating current (AC) dynamometers. When paired with a water-cooled jacket, they significantly lower noise and temperature levels inside the pit. This improves overall safety, makes workers more comfortable, and allows easier detection of undesirable noises.

The right chassis dynamometer can also provide the operator an enhanced user experience with individual speed, torque, and angle control of each wheel/roll. These capabilities are essential for a growing volume of hybrid vehicles, electrified axles, and AWD applications.

Making the right choice for your chassis dynamometer will help future-proof your overall testing efforts. Download this white paper to learn more.
