Hybrid & Electric Vehicle Testing

Electric and hybrid-electric vehicles use a variety of technologies to generate, store and transfer energy. Southwest Research Institute is a premier center for EV and HEV research and development spanning Electric Powertrain Systems and Energy Storage Systems to Lubricant Testing. Our hybrid and electric vehicle testing services provide a pathway to production from bespoke solutions to electric vehicle testing standards. OEMs, suppliers and manufactures trust SwRI for independent solutions for testing electric cars and trucks.

Electric Vehicle Testing Standards

We maintain over 200 test stands, which support both light-duty and heavy-duty testing. All hybrid and electric vehicle testing standards are conducted by experienced engineering and technical staff to provide a turn-key experience. Our longstanding history of powertrain research and testing allows us to handle all types of technical challenges when testing electric cars and trucks.
