| Connector standard | Type 2 AC connector compliant with IEC 62196-2 | Check that the vehicle inlet and the charger connector are both Type 2 compatible. | Vehicles designed for the European Type 2 AC charging system | A Type 2 connector does not determine charging speed by itself; the vehicle’s onboard AC charger also sets the limit. |
| Charging power | 3.7 kW, 7.4 kW, 11 kW, or 22 kW AC | Compare the charger output with the vehicle’s maximum AC input and the site’s electrical capacity. | 3.7–7.4 kW for basic home charging; 11–22 kW where three-phase supply and vehicle support are available | A 22 kW charger will not make a vehicle charge at 22 kW if its onboard charger accepts only 11 kW or less. |
| Rated current | 16 A or 32 A per phase; some units support adjustable current limits | Confirm the continuous current rating, circuit breaker size, cable capacity, and local electrical requirements. | 16 A for lower-power installations; 32 A for higher-power single- or three-phase charging | Charging current should be configured to match the installation, not selected only from the maximum advertised value. |
| Supply arrangement | Single-phase 230 V or three-phase 400 V nominal AC supply | Have a qualified electrician verify the available phases, voltage, earthing system, and spare capacity. | Single-phase for most residential installations; three-phase for faster 11 kW or 22 kW charging | Electrical conditions and permitted installation methods vary by country and building. |
| Charging mode | Mode 3 AC charging with control-pilot communication | Look for compliance with IEC 61851-1 and confirmation of proper pilot and proximity functions. | Home, workplace, apartment, fleet, and destination charging | Mode 3 equipment provides controlled AC charging and safety communication between the EV and charging equipment. |
| Cable configuration | Socket outlet or tethered cable; common cable lengths are approximately 5–7 m | Measure the parking distance, check cable flexibility, and confirm whether a separate Type 2 cable is required. | Socketed units for shared flexibility; tethered units for daily convenience | Avoid using an extension cord unless it is specifically permitted by the equipment and local regulations. |
| Residual-current protection | Residual-current protection with AC detection and appropriate DC leakage protection | Verify whether the charger includes 6 mA DC residual-current detection and identify the required upstream RCD type. | All permanent residential, commercial, and public installations | Depending on the design and local rules, an installation may require Type A protection with DC detection or Type B protection. |
| Enclosure protection | Indoor units and outdoor units with an appropriate IP rating, commonly IP54 or higher for exposed locations | Check the manufacturer’s tested IP rating, operating temperature range, UV resistance, and installation instructions. | IP-rated outdoor equipment for driveways, car parks, and open-sided garages | IP ratings address dust and water ingress; they do not replace correct mounting, drainage, and cable management. |
| Load management | Fixed-current charging, dynamic load balancing, or scheduled charging | Check compatibility with a smart meter, current transformer, solar system, or building energy-management system. | Homes with limited electrical capacity, solar generation, or multiple chargers | Dynamic load management can reduce peak demand, but it must be correctly installed and commissioned. |
| User access and control | Plug-and-charge operation, RFID access, app control, or network-based authorization | Confirm whether access control works offline and whether multiple users can be managed. | Simple operation for private homes; RFID or user management for shared locations | Advanced app features may require Wi-Fi, Ethernet, Bluetooth, or cellular connectivity. |
| Connectivity protocol | Local control, OCPP connectivity, or optional ISO 15118-related functions | Check the exact supported protocol version, firmware-update method, data requirements, and interoperability limits. | Networked homes, commercial sites, fleets, and managed charging systems | Smart-charging and vehicle-to-grid features depend on the charger, vehicle, software, and local grid rules; they are not guaranteed by a Type 2 connector alone. |
| Metering accuracy | Basic energy display or certified billing-grade metering | Determine whether the meter is intended for monitoring only or for regulated billing. | Basic monitoring for private homes; certified metering for tenant, workplace, or public billing | Billing requirements differ by jurisdiction and may require an approved meter and software system. |
| Installation location | Indoor, covered outdoor, or fully exposed outdoor installation | Review wall strength, cable routing, ventilation, clearance, drainage, impact risk, and accessibility. | Select equipment specifically approved for the intended environment. | Do not install an indoor-only charger outdoors, even when it is placed under a small canopy. |
| Safety and certification | Documented conformity with applicable electrical, EMC, and safety requirements | Request the declaration of conformity, installation manual, test information, and applicable certification details. | Every installation, especially high-current or publicly accessible applications | Certification markings should be supported by traceable documentation rather than labels alone. |
| Best-fit selection | Match vehicle capability, daily mileage, available supply, installation budget, and control requirements | Use the vehicle handbook, electrical assessment, and charger documentation before purchase. | A properly installed charger that meets actual usage needs | Higher rated power is not automatically better if the vehicle, supply, or charging schedule cannot use it. |
