New ultracapacitor.Who: PowerCache (San Diego San Diego (săn dēā`gō), city (1990 pop. 1,110,549), seat of San Diego co., S Calif., on San Diego Bay; inc. 1850. San Diego includes the unincorporated communities of La Jolla and Spring Valley. Coronado is across the bay. , CA) What: PC2500 Ultracapacitor Why you should care: The PC2500 (the 2500 comes, we assume, from its 2500-farad capacitance capacitance, in electricity, capability of a body, system, circuit, or device for storing electric charge. Capacitance is expressed as the ratio of stored charge in coulombs to the impressed potential difference in volts. ) is designed to provide short-term power for critical applications during power dips A power dip is a very short drop in voltage in a system (generally home AC wiring). It is most commonly observed when a high-current device (such as a hair dryer, microwave, or table saw) is switched on and lights in the same system will dim momentarily. or interruptions. It is charged from and used in conjunction with a primary power supply such as a battery, fuel cell or generator. Pertinent Data: The PC2500 measures only 161x 62x 61.5 mm and caches 7800 Joules of energy at a nominal 2.5 volts for high-powered discharges ranging from fractions of a second to one minute. PowerCache says that the PC2500 is well-suited (okay, they actually said "perfect") for burst-mode applications such as the acceleration and braking of hybrid electric vehicles A hybrid electric vehicle (HEV) is a vehicle which combines a conventional propulsion system with an on-board rechargeable energy storage system (RESS) to achieve better fuel economy than a conventional vehicle without being hampered by range from a charging unit like an .
