UQM Technologies Inc. says it has received a new and updated China certification on its PowerPhase HD250 electric propulsion system that meets the latest 2015 version of the Chinese general specifications for electric motors and inverters for electric vehicles.
According to the company, the testing, which was conducted over a two-month period at the China Automotive Technology & Research Center in Tianjin, included extensive system performance analysis for power and torque and environmental examinations, including vibration, salt spray, sealing performance and electrical testing.
UQM says its PowerPhase HD250 system is optimized for transit bus and heavy-duty commercial vehicle applications and provides up to 95% system efficiency. The system consists of a high-performance, liquid-cooled, permanent-magnet motor and a high-power, liquid-cooled inverter with a full-featured digital signal processor controller. As reported, this system is used in the recently announced PowerPhase DT drivetrain with a two-speed Eaton transmission for several key China bus customers, including HK Group, Wuzhoulong Motors and ITL.
“This milestone is significant and comes at a time when we are executing on our China expansion strategy. Because of UQM’s high-torque and power-density performance, this certification will allow Chinese customers to be eligible for the highest levels of government incentives,” says Joseph Mitchell, president and CEO of UQM Technologies.
“This official endorsement from a major China certified laboratory shows that our electric propulsion system meets the most current strict standards that have been established by China and is an important step for our partners to achieve full vehicle-level certification,” he continues. “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.”
