An aspect includes a battery charging system (210; 310) for a hybrid electric aircraft (200; 300). The battery charging system (210; 310) includes a generator (212), a battery system (250), and a controller (216). The controller is operable to charge the battery system up to a first charge level (408) based on receiving a first charging current (404) at a power input (252). An operational status of a gas turbine engine (20) of the hybrid electric aircraft is monitored. The battery system (250) is charged at a second charging current (410) received from the generator (212) driven by the gas turbine engine (20) responsive to determining that the gas turbine engine is in a taxi state, where the second charging current (410) is less than the first charging current (404). Charging of the battery system is halted based on detecting a transition (412) of the gas turbine engine from the taxi state to an off-idle throttle state.
