alternator is transferred to the EDLC for storage. By distributing the electricity stored in

EDLC to the vehicle’s electrical components when the vehicle is in the idling stop mode, the

system reduces the need for the engine to burn extra fuel to generate electricity, thereby

improving fuel economy.

The electricity to start an engine will also be supplied from EDLC. This is the first

time in the world that a system to start an engine only using electricity stored in EDLC, has

been adopted in a mass-produced vehicle. By using EDLC instead of a lead-acid battery for

frequent engine starting, the load on the vehicles lead-acid battery will also be reduced and

the life-span of the battery is expected to be prolonged.

EDLC for use in vehicles

have been produced at Chemi-Con

Yamagata Corporation (Nagai City,

Yamagata Prefecture, Japan: 100%

owned

subsidiary

of

Nippon

Chemi-Con) and EDLC modules

have

been

assembled

at

Chemi-Con Nagaoka Corporation

(Nagaoka City, Niigata Prefecture,

Japan: 100% owned subsidiary of

Nippon Chemi-Con).

By also strengthening sales to existing markets such as industrial machinery and UPS

(Uninterruptable Power Supply), Nippon Chemi-Con intends to achieve DLCAP™ sales goal

of 4 billion yen for this fiscal year. Demand for EDLC is expected to increase in industrial

equipment and renewable energy markets as well. Nippon Chemi-Con aims to boost sales of

DLCAP™ to 10 billion yen by the end of fiscal year 2015.
