Guangzhou Armada Development and Guangzhou Yiqi Bus Co. to Purchase 207 Additional Eaton Hybrid Systems for Buses

Guangzhou Armada Development Corporation and Guangzhou Yiqi Bus Company, Ltd. will purchase 207 additional diesel-electric hybrid power systems from Eaton Corporation for application in new buses in Guangzhou.
This purchase adds to the initial installation of 30 Eaton hybrid-powered buses announced in January. (Earlier post.) The buses will be placed into passenger service throughout the year. Once deployed, this will be the largest single placement of hybrid-powered buses in China. It is also Eaton’s largest single hybrid power systems order to date.
Operational results from the initial placement of buses, built by Beiqi Foton Bus Company, since January show that fuel consumption for the diesel-electric hybrid powered buses is nearly 60% less than that of the LPG-powered buses currently in service, with fuel cost savings of about 40%. The system also provides reductions in particulate and NOx emissions.
The Foton-Eaton buses combine a Euro-III compliant Cummins ISBe 5.9L diesel with Eaton’s medium-duty parallel hybrid drive system. Primary components of the hybrid system are the Hybrid Drive Unit (HDU), which combines a clutch, a 44 kW/420 Nm motor/generator and automatically controlled manual transmission; the motor inverter/controller; the DC/DC converter; and a 2 kWh li-ion battery pack from Hitachi.

Guangzhou Yiqi operates approximately half of the transit buses in Guangzhou, a city of 12 million people in China’s Guangdong province.
