Grid-eMotionTM Flash charging system is Hitachi Energy's solution for large-scale electric vehicle charging infrastructure, particularly for public transport. It allows for flash-charging of electric buses at select stops using high-power pantograph charging. This reduces fleet downtime compared to overnight depot charging, allowing buses to remain in service transporting passengers. Hitachi Energy can provide full turnkey solutions from grid integration to charging hardware and software, drawing on over 100 years of grid experience and a decade of e-mobility innovation.

Why flash-charging?
No down time to recharge
13

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

Safety by design
• 4 contacts (+, -, CP and PE)
• The system is still “floating” so even in the
event of a single failure poses no danger of
electrical shock
• The overhead receptacle (or the socket) is
only energised when the bus is connected
• The earth is the first to connect and the last
to break
• The earth between the bus and the charger,
the insulation between positive and earth
as well as negative to earth are
continuously monitored
