Hybrid Electric Power -- Ultracapacitor / Battery


Ultracapacitor -- Battery: Hybrid Electric Power

Combining the high energy density of batteries with the high power density of ultracapacitors, provides a better power profile than either alone.

Speaking of incorporating ultra caps into the electric drive, I recently learned from Mike Millikin1 that PML Flightlink put 350V worth of 11 Farad ultra capacitors into its Mini QED prototype. The ultra capacitors accept power from regen braking and discharge when high current is required for acceleration.

Ultra-capacitor/li-ion battery "hybrids" being developed in China

Maxwell Technologies and Tianjin Lishen Battery, hybrid describes a new sort of energy storage product that combines ultracapacitors with lithium-ion batteries. The two companies recently announced they would partner up to produce this hybrid power source, and samples should be available early next year, possibly in EVs.
