TransPower Is to Build Six Demo Vehicles as Part of CEC-Backed
Clinton Global Initiative-America and National Strategies Program

The California Energy Commission is supporting a project led by Washington, D.C.-based National Strategies to build six battery electric school buses with vehicle-to-grid capability, and deploy them with three California school districts. The V2G-capable buses will be built by San Diego-based heavy duty electric drive specialist TransPower.

CGI-America and partners want them to be cleaner – and cheaper to operate.

The electric school bus demonstration is part of a Clinton Global Initiative – America (CGI- America) Commitment to Action, National Strategies says. CEC has approved a $1.4 million grant coupled with a previously awarded grant from the South Coast Air Quality Management District for a total of $2.2 million.

The six battery buses will be deployed with California’s Torrance, Kings Canyon USD and Napa Valley Unified School Districts.

‘Demonstrate and Document’

“This is the largest demonstration of zero emission school buses in the country and the first to utilize V2G technology to aid in reducing student transportation costs,” National Strategies managing director Kevin Matthews says in a release. “The project will show that we can remove children from diesel emissions and improve air quality while simultaneously reducing the cost of student transportation and supporting the utility grid.”

The goal, states is the announcement “to demonstrate and document that the total cost of ownership of all electric school buses is equal to or less than that of traditional diesel powered school buses.

‘ElecTruck’-Type Componentry

“The demonstration will document the reduced costs of operating all electric school buses through lower fuel and maintenance costs [and] the potential to generate revenue by supplying energy stored in the school buses batteries back to the utility grid when not transporting students.”

Project participants will also evaluate V2B – or vehicle-to-building – technology, “where the school buses can provide power to buildings or other facilities during a power outage or post disaster situation.”

TransPower will use a variant of its “ElecTruck” driveline developed for yard hostlers and other heavy duty electric vehicles, installing the battery electric gear into used 1996 Type C International school bus chassis, president and CEO Mike Simon told F&F. Twin main electric motors are supplied by China’s JJE. They were originally developed for the Fisker Karma. TransPower will use a battery management system dubbed Cell-Saver.
