Wuzhoulong’s Chinese e-bus uses UQM drive system




Shenzhen Wuzhoulong Motors has unveiled a 12-meter bus for the China market, powered by an electric drive system from UQM Technologies (NYSE MKT: UQM).
UQM’s PowerPhase DT HD250 propulsion system includes a 2-speed Eaton transmission and delivers peak power of 250 kW and torque of 3050 Nm.
Wuzhoulong has delivered nearly 3,000 new energy buses, which are running on more than 20 routes in China.


“UQM has very good power density and high performance,” said Mr. Chen Qingquan of the Chinese Academy of Engineering. “The UQM drive system Wuzhoulong used has better performance than the other E-drive suppliers, and the UQM drive system saves in volume and weight.”
“After much hard work getting this bus deployed, we are glad to see the market entry of the UQM drivetrain in China,” said Joe Mitchell, CEO of UQM. “This underscores the move away from direct drive towards more power- and torque-dense UQM motors paired with a 2-speed transmission as the most efficient solution for the transit bus vehicle application.”
