The battery of the hybrid electric powered aircraft discharges at high power for a relatively long time during climb, consuming much electric energy and resulting in more battery weight requirements than the takeoff phase. The selection of battery discharge power and the configuration of battery released energy for each phase in aircraft design are investigated.
