DC charging
FlexDC
A battery-backed charging hub that feeds satellite chargers across your depot. High-power charging where you need it, without the grid connection to match, and fully configurable to your vehicles and your site.
- 20kW–1MW per connector
- Up to 40MW battery storage
- Fully configurable chargers and storage
Two versions
FlexDC Standard
A battery-to-charger satellite system. The fastest way to add high-power charging to an existing depot.
FlexDC DC Bus
The same hub on GridUnlock’s DC bus. Often less installation work, a smaller hardware footprint and fewer groundworks, so capex is lower. Because DC is the root of the technology, you upgrade by changing modules, not replacing metal boxes.

FAQs
How does FlexDC charge more than our connection allows?
The battery fills up when demand is low and releases energy when vehicles plug in, so the chargers can draw more power than the grid supplies at that moment.
How is it configured?
Fully to your needs. Charging power (20kW to 1MW per connector), the number of charging stations and the battery size (up to 40MW) are all specified for your site and fleet.
Can we move from Standard to DC Bus later?
Yes. The upgrade is a big step up in capability, yet typically needs less installation work than adding conventional chargers. On DC Bus, future upgrades are modular.
Not sure which charger fits your site?
Run the Site Check for a recommended setup, or talk it through with an engineer.
