In late November, I put in an order for a Model Y Long Range and am really excited about getting it. And even more excited now that we have seen it is the flesh (display model in London Westfield). But I have a number of questions about home chargers.
I am lucky enough to have a three-phase electricity supply at home (but it is not particularly well located in relation to where the car will be parked overnight). Given that the Model Y has a charge rate capped at 11kW, it seems that there isn’t a huge advantage over a single-phase 7.4kW charge.
Q1: Is there any likelihood of this 11kW cap being raised? Is it a software thing (i.e. an OTA update could change it) or a hardware thing (i.e. it is hard-baked into the car)? If the charge rate was raised to 22kW, the benefit would be more noticeable.
As I mentioned, the three-phase supply it not brilliantly located. The tethered cable on every charger is too short. I reckon I need 11m minimum.
Q2: Am I able (or is it safe) to add an extension cable (say, 5m long) to the end of the cable? And, if so, can that extension cable be left attached when not in use?
The alternative is to go for a single-phase 7.4kW charge, which will allow much more flexibility on location.
Q3: My ideal spot is on a part of the house which is brick construction but is weather-boarded from about two feet upwards. I have a feeling that a charger can only be attached to brick/stone/render and that it is against regulations to attach it to wood. Is that right?
Finally Q4, which brand of charger? I like the look of the Tesla Wall Connector but it is expensive (esp given that it doesn’t qualify for the OZEV/EVHS grant). However, if I go down the three-phase route, it looks as though it might be the cheapest option.
As an alternative, the Ohme charger appears to be a good option. But it looks as though I am unlikely to get anything installed before 31st March so I’ll miss out on the OZEV/EVHS grant.
Any advice would be gratefully received.
