I would recommend installing a 32a 220v single-phase outlet in preparation for the wall connector. If possible, having your carport wired to provide a higher amount of power would provide more flexibility than wiring for a 13a socket. By having a 40amp breaker, and the appropriate wiring, you will be able to dial the amperage up to 32a or to as low as 10a to suit your individual needs.
This more recent strategic change is based on some negative long term test results we received on the BS1363 outlets. Our testing has shown that the BS1363 outlets are not robust enough to handle the continued stress that high volume electric vehicles will subject it to, even if configured to 10A. The outlets are home outlets essentially designed for lamps and desktop computers: they were never conceived or designed to handle an electric vehicle’s unique needs. We want to assure you we continually looking for solutions to provide the safest most reliable public charging and are actively working with HK Electric and CLP to achieve this goal. They have offered us great support thus far so we are excited to see what we can do together for our Hong Kong.
