With the growing requirements to improve fuel economy and reduce emissions, car manufacturers are responding by developing more hybrid electric vehicles (HEVs) and fuel cell hybrid vehicles (FCHVs).

Since the 1990s, DENSO has closely worked with car manufacturers to develop state-of-the-art components for those hybrid vehicles. In 1997, DENSO started supplying components for HEVs, including a battery electronic control unit (ECU) and DC-DC converter.

In 2001, DENSO launched the world’s first belt-driven integrated starter generator (ISG) that integrated the starter with the alternator, realizing an idle stop function.
In the field of air conditioners for hybrid vehicles, DENSO launched the world’s first carbon dioxide (CO2) air conditioner for FCHVs in 2002, and an electric air conditioner for HEVs in 2003.

DENSO can supply components to various types of hybrid vehicles and help to create new generation vehicles.
