| 1. Charging use | Location and expected dwell time | Home, workplace, and overnight parking commonly suit AC charging. Public sites serving drivers who need shorter stops may require DC fast charging. | Estimate daily energy needs, parking duration, number of vehicles, and expected simultaneous charging sessions. |
| 2. AC station output | Power rating and electrical supply | Common AC ratings include about 7.4 kW at 230 V single-phase, 11 kW at 400 V three-phase, and 22 kW at 400 V three-phase. Actual output depends on the vehicle’s onboard charger and the installation. | Confirm the supply voltage, phase, available current, and vehicle compatibility with a qualified electrician. |
| 3. DC station output | Power, grid capacity, and vehicle charging limits | Commercial DC equipment is available across a broad range, often from around 50 kW to several hundred kilowatts. A vehicle’s battery and charging curve may limit the power it can accept. | Request a site load assessment and confirm utility capacity before selecting a power rating. |
| 4. Connector compatibility | Country, vehicle fleet, and charging standard | Connector standards vary by market. Type 2 is widely used for AC and CCS2 for DC in Europe; North American sites may need to account for J3400 (NACS) and CCS1 vehicles. Confirm current vehicle and local requirements. | List the vehicles that will use the site and verify connector availability, cable reach, and any applicable adapter policy. |
| 5. Electrical installation | Panel capacity, circuit protection, and cable route | Each installation must be sized to the equipment specifications and applicable local electrical codes. A dedicated circuit, suitable overcurrent protection, grounding, and correctly sized conductors may be required. | Have a licensed electrical professional inspect the panel, cable distance, mounting location, and required permits. |
| 6. Site and environment | Mounting, exposure, access, and protection | Check whether the unit is intended for indoor or outdoor use, its stated environmental rating, available mounting method, vehicle clearance, lighting, and protection from impact or water ingress. | Measure the parking area and cable reach; confirm accessibility and local safety requirements for the intended site. |
| 7. Connectivity and software | Network coverage and system integration | Stations may support Ethernet, Wi-Fi, or cellular connections. If connecting to a charging management platform, check supported OCPP versions and required features with both providers. | Verify signal strength at the installation point, network costs, remote monitoring, user access, and payment requirements. |
| 8. Load management | Multiple stations and demand limits | Load management can help distribute available electrical capacity among charging points, but its functions and installation requirements depend on the equipment and site design. | Ask whether dynamic load management is supported and what additional meters, controllers, or network connections are needed. |
| 9. Purchase and installation quote | Scope, exclusions, and schedule | A complete quote should distinguish the charging unit from electrical work, trenching, cabling, networking, permits, commissioning, and any required utility upgrades. | Request an itemized quote, written installation scope, warranty terms, commissioning plan, and confirmation of who obtains permits. |
| 10. Final confirmation | Specifications and readiness to install | Before ordering, match the selected model’s power, connector, supply, mounting, connectivity, and environmental specifications to the approved site design. | Obtain written confirmation from the installer that the chosen equipment is suitable for the site and local requirements. |
