Electric drive system technology developer for commercial vehicles, Balqon Corporation, says it has entered into a Joint Development Agreement with Polar Power to develop a series plug in hybrid system for its line of heavy duty electric trucks and buses.

With the agreement, both companies will work towards development of a 40kw on-board DC hybrid generator to charge batteries during the daily drive cycle to increase vehicle range.

"Integration of on-board generator [s] in our 2014 model year vehicles allows us to address increased range applications for heavy duty trucks and buses used at ports, airports and distribution warehouses, while still providing our customer [s] with lower operating cost [s] and emissions of an electric drive train," said Balqon Corporation president and CEO, Balwinder Samra.

"We believe Polar Power's decades of experience in developing and integrating DC-powered generator systems provides us the opportunity to jointly address the growing need for lower emission heavy duty vehicles in global markets," he added.
