When businesses ask what a DC fast charger costs, they usually mean the charger itself. In practice the hardware is one line among many. Knowing every line helps you compare quotes properly and avoid surprises.
1. Charger hardware
Usually the largest single item. Price depends on power rating, number of guns, connector types, power sharing and brand. A 120 kW dual-gun unit costs considerably more than a 30 kW single-gun one.
2. Electrical supply and connection
This is the line that varies most between sites. It can include utility application and connection fees, a higher sanctioned load, and in many DC projects a new transformer. If the grid connection needs upgrading, this can rival the cost of the charger.
3. Electrical installation
Panels, switchgear, protection devices, cabling from the supply point to the charger, earthing and metering. Long cable runs add cost, which is why charger location matters.
4. Civil works
Foundations or plinths, trenching for cables, bollards to protect the charger, canopies, lighting, parking markings and signage.
5. Design and approvals
Site survey, electrical design and drawings, and the permits and inspections your state requires.
6. Software and connectivity
Onboarding the charger to a charge point management system, payment setup and a data connection. Often charged as a yearly or monthly subscription.
7. Installation, testing and commissioning
Labour to mount and connect the charger, safety checks and live charging tests before go-live.
8. Ongoing costs
- Electricity: energy charges plus demand charges based on your peak power.
- Maintenance: preventive servicing and repairs after warranty.
- Operations: monitoring, driver support and payment processing.
- Insurance for the equipment.
What lowers the total
- Placing chargers close to existing power.
- Using spare capacity on your current connection where possible.
- Planning cable routes and capacity for future chargers in phase one.
- Checking available subsidies and state EV policy incentives.
