| 1 | Electrical Safety Certification | Choose equipment evaluated to applicable electrical-safety standards for electric-vehicle charging equipment, such as UL 2594 and UL 2231, or equivalent standards recognized in your region. | Look for a verifiable certification mark and installation instructions that identify the required circuit, grounding, and protection devices. | Independent certification helps confirm that the charger has been assessed for electrical shock, fire, and abnormal operating conditions. |
| 2 | Ground-Fault and Leakage Protection | Verify that the station provides ground-fault protection and, where required, protection against both AC and DC residual current. | Confirm the protection type, trip behavior, reset method, and whether an upstream GFCI or equivalent device is also required by local code. | Leakage protection reduces the risk of electric shock if current escapes from the normal charging path. |
| 3 | Electrical Capacity and Circuit Sizing | Match the station's output to the home's service capacity, breaker rating, wiring, and the vehicle's maximum AC charging rate. | For continuous charging loads, installation commonly uses a circuit rated at least 125% of the maximum continuous current, subject to local electrical code. | Correct sizing helps prevent overheating, nuisance trips, voltage drop, and costly electrical upgrades. |
| 4 | Charging Power and Adjustability | Compare maximum current output with the vehicle's onboard charger and select a unit with adjustable current settings when available. | Common home AC charging levels include approximately 7.2 kW at 32 A and 9.6 kW at 40 A on a 240 V supply; actual charging depends on the vehicle. | Adjustable output can accommodate limited electrical capacity, time-of-use schedules, and future changes to the vehicle or home. |
| 5 | Weather and Enclosure Protection | For outdoor installation, assess the enclosure rating, UV resistance, drainage, cable sealing, and operating temperature range. | An enclosure rated NEMA 3R or higher is designed for outdoor exposure; an IP54 rating provides protection from dust ingress and water splashes. Always follow the product's stated rating. | Adequate protection helps limit corrosion, moisture intrusion, freezing-related damage, and premature component failure. |
| 6 | Cable, Plug, and Connector Durability | Inspect cable flexibility, connector ergonomics, strain relief, storage hooks, locking features, and resistance to abrasion and repeated bending. | The connector should latch securely to the vehicle, remain protected when not in use, and be manageable at the planned parking distance. | A durable cable and connector reduce tripping hazards, mechanical wear, contamination, and charging interruptions. |
| 7 | Smart Controls and Remote Access | Evaluate scheduling, remote start and stop, current adjustment, charging history, notifications, and software update procedures. | The core charging function should remain usable if Wi-Fi or the cloud service is unavailable, with local controls or a defined offline mode. | Smart controls can reduce charging costs and provide useful visibility without making basic charging dependent on an internet connection. |
| 8 | Energy Monitoring and Load Management | Check whether the station measures energy consumption and can coordinate charging with other major household loads. | Useful features include kWh tracking, adjustable charging limits, scheduled operation, and dynamic load management where supported by the installation. | Monitoring supports cost control, while load management can help avoid exceeding the home's electrical service limit. |
| 9 | Installation, Location, and Accessibility | Plan the cable route, mounting height, parking position, ventilation clearance, service access, and protection from vehicle impact. | Use a qualified electrician where required, maintain code-required clearances, and avoid placing the station where the cable crosses a regular walkway. | Good placement improves daily convenience and lowers the risk of cable damage, accidental impact, or unsafe handling. |
| 10 | Warranty, Support, and Future Compatibility | Review warranty duration, replacement procedures, technical support, firmware policy, connector compatibility, and access to installation documentation. | Prefer clearly stated coverage, support contact methods, repair or replacement terms, and compatibility with the vehicle and electrical system you plan to use. | Reliable support and documented compatibility protect the investment and reduce downtime if hardware or software problems occur. |
