Enova Systems is the electric drivetrain provider for Navistar’s hybrid-electric school bus, the Navistar IC CE Series yellow bus. Navista, owns 61% share of the school bus market in North America.

Introduced in 2006, Navistar’s CE Series school bus utilizes an 80kW Enova Systems hybrid drive train and a 38kWh Valence Technology U-charge lithium phosphate energy system, that feature Valence command and control interactive logic.

The company claimed that the hybrid-electric system improves fuel economy by up to 65% and reduces greenhouse gases by up to 39%.

R Adleman, vice president of sales and marketing at Valence Technology, said: “School districts across the US trust Enova Systems and Navistar to transport their students safely, efficiently and with a reduced impact on the environment.

“And as evidenced by the new orders, Enova and Navistar continue to place confidence in Valence Technology to deliver proven, safe and reliable battery systems that enable significantly-improved fuel economy and a decrease in greenhouse gases.”

John Mullins, chief operating officer of Enova Systems, said: “The latest order with Valence Technology will help more school districts reduce their carbon footprints and transport children safer and quieter.”
