Bus & Coach Charging

Zero-emission depots. At scale.

Smart depot charging for electric buses and coaches. Automated overnight scheduling, demand management, and ZEBRA-eligible infrastructure for UK and European fleet operators.

Unmanaged charging creates MW-scale demand spikes.

A fleet of 20 buses returning at 20:00 and all plugging in simultaneously can demand 4–8 MW in the first hour — far beyond most DNO connection allowances. Without smart scheduling, operators face DNO penalty charges, curtailment events, or simply can't charge all vehicles before the morning shift.

  • DNO demand caps as low as 500 kW for many depots
  • All buses return within a 3-hour window — then must leave by 06:00
  • Mixed fleet: single-deck, double-deck, coaches — varying battery sizes
  • Route data determines minimum departure SOC per vehicle

Master + terminals + BESS.
The complete depot stack.

One architecture covers depots from 10 to 500 buses. The Fleet Master handles dynamic load distribution; BESS absorbs overnight cheap-rate energy; Electron CMS schedules every bay against each vehicle's departure time and route requirement.

Fleet Master Unit 480 kW

Fleet Master Unit

240 or 480 kW centralised power module distributes to up to 6 satellite terminals. Dynamic load sharing ensures maximum utilisation of every kW within the DNO limit.

Power Hub BESS 215kWh
Peak Shaving
Integrated BESS

Power Hub 215 kWh units stack to absorb off-peak grid energy and discharge during demand peaks — reducing DNO demand charges and unlocking additional charging capacity.

Every bus charged.
Every departure met.

Electron CMS ingests the next day's route schedule and automatically builds a charging plan that maximises cheap overnight rates, stays within the DNO limit, and guarantees every vehicle reaches its required departure SOC.

  • Route-aware scheduling — minimum SOC per vehicle per route
  • Half-hourly tariff optimisation — charge when electricity is cheapest
  • Hard DNO cap enforcement — no demand limit breaches
  • Live dashboard with bay-by-bay SOC and energy cost per vehicle
