SEOUL,  KOREA -  TORRANCE,  CA  March  19,  2003  --  Enova  Systems,  Torrance,
California  (Symbol  OTCBB:  ENVA)  announced  today  that it has signed a joint
venture  agreement  with Hyundai Heavy  Industries,  Co, Ltd. (HHI) to create an
advanced  technology  corporation  (ATC) for research and  development.  The new
entity will be initially based at Enova's Torrance California headquarters.

The technology center's mission will be to advance current technologies of Enova
and HHI,  and to create new  intellectual  property and  products.  The ATC will
pursue  research  and  development  projects in advanced  power  management  and
conversion programs for mobile and stationary power applications.

In  conjunction  with  the  joint  venture,  HHI will be  making a US$3  million
investment  in Enova  Systems  through the  purchase of new common  shares.  The
investments  in the joint venture by both companies are discussed in HHI's press
release of March 18, 2003.

Carl Dean Perry,  President and CEO, stated, "This partnering with Hyundai Heavy
Industries represents a key milestone in Enova's growth. Building on our already
strong  manufacturing  relationship,   the  ATC  will  enhance  both  companies'
abilities to develop and penetrate new markets. This joint venture is a positive
addition  to  Enova's  and HHI's  long-term  strategies.  The  technologies  and
products slated for the ATC will encompass HHI and Enova's world-class expertise
in the  areas of  environmentally-friendly  power  generation,  transition,  and
distribution  technologies for mobile and stationary energy systems.  I strongly
believe this teaming underscores our partner's  commitment to both Enova and the
future of advanced technology power systems."
