Electrical Storage, not Just for Electric Cars.

Hybrid, gas and electric cars benefit by using Ultracapacitors as supplemental power sources. Engine start/stop and regenerative braking systems already use Ultracapacitors for their fast charging, high charge cycle count, and high output current. Electric cars can use Ultracapacitors for peak-power shaving during acceleration allowing for a smaller main battery.

Regenerative braking systems are not new and have found usage in a number of hybrid bus and truck systems over the years. Ultracapacitors are used to increase the efficiency with which these systems can store power. Today we are beginning to see the power stored from regenerative braking being used in electric, hybrid, and gas cars like the Mazda i-eloop system (which uses an Ultracapacitor). Mazda estimates a 10% increase in fuel efficiency of its gas vehicles by using the power regeneration from the brakes along with the start/stop system. Electric vehicles use the power in an Ultracapacitor to provide the peak current needed during an acceleration event allowing for a smaller primary power source.

Primary power systems are designed around the peak power requirement but with the addition of an Ultracapacitor the primary power can be designed around the average power requirement. The Ultracapacitor handling peak power draws (for example during acceleration). This has advantages across many vehicle including downsizing the battery requirements in electrical vehicles, increasing performance in a small gas engine and downsizing the required fuel cell in fuel cell vehicles.
