Two studies exploring battery costs for hybrids and plug-ins: LEESS, PHEV20, and PHEV40

Green Car Congress

For PHEV20 batteries, TIAX found significant overlap in battery costs among five cathode classes, with wider variation within each chemistry based on the electrode design than between chemistries. For PHEV20, the program focused on both commercially available and emerging cathode materials aimed for use in a 20-mile PHEV battery pack.

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.
