Mustang Advanced Engineering (MAE) designs and manufactures made-to-order test stands for various EV projects, including drivetrains (electric motor, power supply and inverter) and electric axle testing projects. MAE recently delivered a test stand to heavy-duty EV manufacturer Proterra.
The system includes a 350 hp regenerative AC dynamometer, 350-700 VDC 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 the company’s power packs. These tests are conducted under fully-loaded conditions; every drivetrain is tested prior to being installed in the vehicle. MAE provided the capability to flash the drivetrains 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 drivetrain test stand demonstrates this expertise,” said VP David Ganzhorn.
