ANL Project on Actively Coupled Ultracapacitor-Battery System for PHEVs Attracting OEM Interest

Green Car Congress

The actively coupled ultracapacitor-battery system has four primary components. and Gold Peak Battery-USA are research partners in the project. The ultracapacitor bank actively coupled via the power electronics allows the use of an energy optimized battery by reducing peak loads and minimizing internal battery heating.

Study Finds PHEV Li-ion Cells Show Little Capacity Fade Under Combined Driving and V2G Usage; Economic Model Suggests Incentives Will Be Required for Vehicle Owners to Participate in V2G

Green Car Congress

A new draft working paper published by the Carnegie Mellon Electricity Industry Center concluded that a PHEV pack comprising lithium iron phosphate cells would incur little capacity loss from combining vehicle-to-grid (V2G) activities with regular driving. The battery pack energy capacity was assumed to be 16 kWh.
