  13. 13. © Hitachi Energy 2021. All rights reserved. Why flash-charging? No down time to recharge 13
  14. 14. © Hitachi Energy 2021. All rights reserved. Operating your eBus fleet with flash charging Range is not the constraint but time Buses present a particular challenge as operators want the vehicles on the road transporting passengers, rather than transporting batteries or waiting at charging stations. The energy will have to be taken on somewhere, the question is where is the most economically efficient place to do so? Timetable High-power in-route charging at selected bus stops and short layover time at terminal provide same driving hours and commercial speed as a diesel fleet High-passenger capacity (up to 4,000 passengers/h) Smaller battery and having all technology mounted on the roof means more space and weight available free to carry passengers. Long-life battery Due to in-route charging principle, the high-power/low-energy battery pack is used in its optimal operating range Grid compatible Connection fee and energy cost minimized through embedded peak shaving functionality Light infrastructure at depot Either free parking after fast (4-5 min) high-power charging upon arrival or low-power (50 kW) mutualized charging 14
