Most charging networks were built around one assumption: drivers charge at home, then use rapid chargers on motorways for long journeys. But in dense cities like London, many drivers do not have private parking, while taxis, Ubers, delivery drivers and high-mileage users need quick local top-ups during the day — not only slow overnight charging scattered around the city or motorway stops far from their homes.
The problem is that rapid chargers need large power connections, and many otherwise perfect urban sites cannot support them without expensive, slow and uncertain grid upgrades. Furthermore site economics, revenue and profitability are not always top-notch.
PowerPledge solves this with battery-backed charging. The battery slowly fills from the site’s spare electrical capacity, like a cistern refilling between flushes, then releases high power when an EV needs a rapid charge. Small amounts of unused capacity become rapid charging capability — deployed faster, with lower electricity costs and no upfront cost to the host. This opens up many more locations for a plug-and-play solution, including sites with strong driver throughput and attractive economics. Because the battery can charge when electricity is cheaper and discharge when rapid charging is needed, PowerPledge can improve charging margins while still offering drivers a lower-cost rapid charge.
Unlike standalone chargers, PowerPledge hubs also have a protected revenue stack. If EV charging utilisation is lower than expected, the battery can still create value through bill reduction, peak shaving, or energy trading where grid approvals allow. This means the battery discharges back into the host site lowering its originaal electricity bill. In high-footfall locations, chargers and batteries can also support advertising screens, vending machines and other on-site revenue streams.
