Enova Teams with Tomoe of Japan to Build Electric Trains for Singapore; Largest Production Contract in Company History.

TORRANCE, Calif. -- Enova Systems, Torrance, Calif. (OTCBB:ENVA), a developer and manufacturer of electric, hybrid and fuel cell digital power management systems, announced today that it has entered into a contract with Tomoe Electric Manufacturing Company of Japan (Tomoe) for the development and production of eight 36-ton battery electric locomotives for Singapore's Land Transport Authority (LTA) under sub-contraction from Hitachi Plant Engineering and Construction Company, Singapore. Enova will utilize components and expertise from Hyundai Heavy Industries of Korea (HHI), the Company's hybrid technology development partner, to meet Tomoe's requirements for the locomotives. The hybrid-electric locomotives will be utilized as service vehicles for the Singapore Mass Rapid Transit Circle Line system for maintenance, repair, shunting and recovery of passenger trains. The first trains are scheduled for delivery in Summer 2006.

Under the terms of the contract, Enova will supply to Tomoe a complete hybrid-electric drive system and technical expertise for integration into the locomotives. Enova is the prime contractor for the heavy-duty drive systems, developing and producing the advanced battery charger and battery management systems.

Masami Mochizuki, President and CEO of Tomoe, stated, "Enova's pure electric and hybrid electric drive systems have been successful in many Tomoe industrial vehicles including our mine crawler. Based on our experience with Enova, Tomoe recommended the Enova/HHI system to Hitachi and the LTA. We are very pleased to be working with such a committed and hard-working partner as Enova on this project."

It is anticipated that the hybrid drive train components will be delivered in late 2005 at Tomoe's Japan-based facilities. Enova anticipates the total contract to exceed $3 million US over the life of the contract, making this the largest production contract for hybrid vehicle components in Enova's history. This latest market penetration in Asia enhances not only Enova's alliances with both Tomoe and HHI, but also advances Enova's hybrid-electric technologies in high voltage power management components. As part of this contract, Enova will develop a high voltage charging system to enable the locomotive to receive a direct battery charge from the high voltage rail.

"This battery electric locomotive project is a significant contract for Enova in terms of alliance building, revenue and advancement of our technologies. Enova is once again proving the adaptability of its hybrid drive systems to a wide range of vehicle applications. Enova continues to seek additional industrial and transit applications in which its technologies may be utilized," remarked Carl D. Perry, president and CEO. "Tomoe is one of Enova's premier customers in Asia. Enova is privileged to be chosen by Tomoe and its alliance partners for this very significant alternative energy project for the Singapore Land Transport Authority."
