ANL Project on Actively Coupled Ultracapacitor-Battery System for PHEVs Attracting OEM Interest
Green Car Congress
MAY 20, 2009
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. Results of an earlier simulation study of capacitor sizing for the system shows that a 75-100 Whr capacitor bank is appropriate for a Saturn VUE-sized PHEV.
