End-Of-Line Testing Systems For Electric Vehicles

By Mike Brezonick22 September 2020

Mustang Advanced Engineering (MAE), a Twinsburg, Ohio, manufacturer of custom test stands for electric vehicles (EVs), said it recently delivered a test stand to heavy-duty EV builder Proterra for end-of-line and/or research and development testing of Proterra’s electric powerpacks.

The system MAE delivered included a 350 hp regenerative ac dynamometer, a 350 to 700 V dc programmable battery simulator, a cooling circuit with chiller and digital controller, vibration measurement, data acquisition and MAE’s TestCell software package tailored to meet the customer’s unique needs.

For Proterra’s South Carolina facility, MAE designed and built a test stand that tests its electrified powerpacks. The tests are under fully loaded conditions and every powerpack is tested prior to being installed in the vehicle to ensure quality standards are met prior to the product being delivered to Proterra’s customers. MAE provided the capability to flash the powerpacks with the appropriate firmware and test it under in-use conditions.

“MAE specializes in making test stands that are made to clients’ specific needs, and the Proterra powerpack test stand demonstrates this expertise,” said David Ganzhorn, MAE’s vice president of Sales. “There is no project that is too big or too small for the MAE team.”
