| Charging power and supply | Match the charger's phase and maximum current to the vehicle, the property's electrical supply and the installation design. | Typical AC examples include approximately 7.4 kW at 32 A on single-phase 230 V, and approximately 11 kW at 16 A or 22 kW at 32 A on three-phase 400 V. Actual output depends on the vehicle and available supply. | Have a qualified electrical professional assess the supply capacity and circuit before choosing a power rating. A higher-rated charger does not make a vehicle charge faster than its onboard AC charger allows. |
| App and connectivity | Check whether the charger supports Wi-Fi, Bluetooth or another connection method, and whether its core functions still work when internet access is unavailable. | Common app functions include starting or stopping a session, viewing charging status and reviewing energy use. Features vary by model and software. | Check the connection quality at the proposed parking location. Confirm whether app access, remote control or cloud services require an ongoing subscription. |
| Scheduling and energy management | Look for scheduled charging, adjustable current limits and dynamic load management if the property has other large electrical loads. | Load management can adjust charging current in response to measured site demand, when the charger and required metering equipment support that function. | Scheduling may help users choose preferred charging times, but electricity tariffs and availability depend on the user's supplier and tariff plan. |
| Access control | Compare app authentication, RFID access cards, user permissions and the ability to restrict charging. | RFID or account-based controls can help limit use to authorised users. Availability and user-management options differ across products. | Useful for shared parking or driveways where access needs to be controlled. Check that the chosen method is practical for every regular user. |
| Enclosure IP rating | Check the complete IP code on the product documentation and confirm that it applies to the installed enclosure and configuration. | Under IEC 60529, the first digit describes protection against solid objects and dust; the second describes protection against water. IP54 is dust-protected and protected against water splashes. IP65 is dust-tight and protected against water jets. | For a partly exposed location, consider the expected rain, wind-driven water, dust and installation position. An IP rating alone does not guarantee protection against every weather condition or incorrect installation. |
| Residual-current protection | Check the specified residual-current protection and whether DC leakage detection is built in or provided by the installation. | EV charging equipment needs appropriate protection against residual current. Depending on the equipment design, this may include Type B protection or Type A protection together with 6 mA DC residual-current detection. Follow the manufacturer's instructions and applicable installation requirements. | Ask the installer to verify the protective-device arrangement for the specific charger and circuit. Do not assume that every charger includes the same protection. |
| Electrical and temperature protections | Review documented protections such as overcurrent, overvoltage, undervoltage, earth-fault monitoring and temperature monitoring. | Protection functions vary between products. Check the product documentation and the applicable EV supply equipment requirements, including IEC 61851-1 where relevant. | Use a dedicated circuit designed for the charger's rated current. The installation should be assessed for the site conditions and completed in accordance with applicable Malaysian requirements. |
| Cable and connector | Confirm connector compatibility with the vehicle, cable reach, cable management and whether the cable is tethered or socketed. | AC connector type and charging capability must match the vehicle and charger. Cable length and connector options are product-specific. | Measure the parking position before purchase. Keep the cable route clear of walkways, vehicle tyres and locations where it could be damaged. |
| Installation and support | Check the installation scope, commissioning, warranty terms, service availability and access to replacement parts. | Installation requirements depend on the site's wiring, protective devices, earthing arrangement and supply capacity. | Use a qualified professional familiar with EV charger installations and applicable local requirements. Confirm who is responsible for inspection, testing and commissioning. |
| Quick selection guide | Prioritise features according to the parking location and how the charger will be used. | Outdoor parking: assess enclosure rating and exposure. Shared parking: consider access control. Limited electrical capacity: consider adjustable current and compatible load management. | Compare the full installation and operating requirements, not just the charger’s headline power or IP rating. |
| Important: Ratings and features are selection criteria, not a substitute for a site assessment. Verify the exact product documentation, vehicle compatibility and applicable Malaysian electrical requirements before installation. |
