HNordic DC-DC EV charger

30%

Up to 30% more profit from the same energy

Conventional EV chargers convert AC grid power to DC for the vehicle — wasting approximately 30% in the process. HNordic's DC-to-DC chargers eliminate that conversion entirely by connecting directly to the battery.

Why DC-to-DC

The efficiency case for direct battery charging

Advantages
No conversion losses

Direct DC eliminates the AC-DC-AC chain

Standard chargers convert grid AC to DC for the vehicle, losing energy as heat at every step. DC-to-DC bypasses this entirely.

Grid independence

High-power charging without a grid upgrade

The battery absorbs grid power gradually and delivers it at high rates on demand. Sites with limited grid capacity can support 120--240 kW charging without infrastructure investment.

Integrated system

Part of the same infrastructure stack

HNordic EV chargers share battery capacity with the BESS installation — managed as a single system, with no redundant hardware.

System integration

Part of a complete energy infrastructure stack

Integration

Paired with BESS

EV chargers share the same battery system as the BESS installation — no duplicate hardware, no competing management systems.

Parking garage applications

The reference project combines 4 vertical wind turbines, 860 kWh battery storage, 20 × 22 kW chargers, and 2 × 240 kW chargers — all DC-to-DC, fully integrated.

Revenue stacking

EV charging income sits alongside energy arbitrage, frequency regulation, and peak demand suppression — from the same installed battery asset.

Scalable deployment

From a single charger alongside an existing BESS installation, to a full multi-charger parking hub. The system scales with site and demand.
