On a 2014 Fusion Energi Is it possible to charge the high-voltage Energi (7.6 kWh Lithium-ion) battery from excess electrical energy generated by the gas-powered engine and/or regen braking system when in hybrid power mode? The left-side multi-function display seems to indicate that more power is going into the battery while in hybrid mode, but the EV battery level never seems to increase. Or is there a separate EV mode battery from the hybrid mode battery? Anyone know the details on how the hybrid charging works and whether it is charging the same battery used in EV mode? Thanks.
