The challenge
Overnight-only AC charging would not cover the daily duty cycle, but there was no room in the yard for a large DC cabinet next to each bay.
Solution
- One 720 kW liquid-cooled power cabinet located at the yard perimeter
- Six dispensers placed between vehicle bays, each with two guns
- Liquid-cooled cables rated to 600 A for high-power daytime top-ups
- Dynamic power allocation prioritising buses with the earliest departure
Implementation
1Duty cycle review with the operator
2Layout design and cable routing plan
3Staged commissioning bay by bay
Outcome
- 24 buses covered by 12 charging points
- Full daily duty cycle met without changing the timetable
- Depot kept its existing electrical service
