Colorado-based motor manufacturer UQM Technologies (NYSE MKT: UQM) has received an updated Chinese certification for its PowerPhase HD250 electric propulsion system. The testing, conducted at the China Automotive Technology & Research Center, included system performance analysis for power and torque, vibration, salt spray, sealing performance and electrical testing.

UQM’s PowerPhase HD250 system, designed for heavy-duty drive applications, provides up to 95% system efficiency, according to the company. The system consists of a liquid-cooled permanent magnet motor and a liquid-cooled inverter with a digital signal processor controller. It is used in the new PowerPhase DT drivetrain with a two-speed Eaton transmission by several Chinese bus manufacturers.

“This certification will allow Chinese customers to be eligible for the highest levels of government incentives,” said UQM CEO Joseph Mitchell. “This official endorsement from a major China certified laboratory shows that our electric propulsion system meets the most current Chinese standards, and is an important step for our partners to achieve full vehicle-level certification. This certification is mandatory to do business in China, and with our transit bus trials now underway, this will help our China customers move closer to rapid deployment and volume sales.”
