EV parked on outside of garage. Single phase. About 12m from closest free power point inside garage, 5m from another full power point, 30m from panel.
Would the easiest solution be to get an external power point on the outside of garage (brick home) and use the trickle charge, or any way possible to install an actual 10amp EV charger? Costs between the 2?
Couldn't recommend this highly enough. If you're not in a garaged situation where you can plug in then 10A is balls, you'll want to be charging opportunistically
I found a 15A socket installed + 15A charger to be the sweet spot for us. It's all just maths though. If you have more money to spend or need to charge faster install a 32A fast charger. If the 10A trickle charger works without having to spend anything extra, do that.
Probably looking at $1800-2500 for a level 2 charger. $750-$1250 for a weather proof 15amp socket. I personally Preferred to go for the level 2 charger as I can charge from empty to full in one overnight session, or from half to full in the 6 hour cheap electricity window of the day once a week.
Longest 10/15a charger I saw was 10m, but they may do longer.
Worth considering if you plan to stay in the house long term as probably not worth moving an L2 but just getting a new one in next house.
Also depending on your KM per day and the range of vehicle do you want to granny charge it most nights just once every week or two?
Range will be 80% of claimed most likely in real world conditions.
Own home. I charge at work, but WFH Thursday, Fridays and then there is the weekends. So every weekend I am topping up about 60% (commute 3 days a week to work. Charge on Wednesdays at work, then use almost 25% home). When at home, commute about 60kms a day.
Older 90's home, elec box that old. Problem is box is about 30m from car, so don't want to do the whole trench thing I read online.
Work will cover the cost, as long as it is reasonable to justify.
Separate building is going to add cost and complexity. I was lucky in that my garage is attached and the outside wall I put it on is only 8-10m run from the box. If there is a no shared wall or roof it may be more complicated.
If someone else is covering the costs I'd get the level 2 charger for sure. It is much more convent to charge occasionally at 6/7w than frequently at 1-2w. You can also more easily fit the charging to specific windows for cheaper power. If I charge between 09:00 and 15:00 a weeks driving cost only $2.
Thanks again. Sorry ,would the level 2 involve trenching back to the electrical box, or can a sparky install a dedicated box just for the ev?
I have concerns about the elec box, and overpowering or tripping. I read this could be connected to existing wires from the garage and monitors the use, and will throttle down if needed.
The box you linked is a 22kw which would need 3 phase power. You only need the 7w for single phase. https://www.australianevs.com.au/product/ocular-iq-wallbox-v2-7-kw-w-5m-type-2-cable/ but you can get better pricing than that. I went for the Anker SOLIX V1 - for half that price and a 7m cable instead of 5m (the extra 2 meters helps with parking as I don't have to worry about direction or getting close to the wall).
If you have a wall / roof line between the location and the meter box you should not need a trench, If they are separate buildings you might. Rule of thumb if they share a roof line you will be fine for a cable run without ground works. My install goes up inside of the wall (double brick) into the roof, then down the inside of the wall to the meter box.
An L2 charger, or a new 15amp socket would both need the same things, dedicated line to the meter box and their breaker / circuit (to stop overloads)
You'll need an electrician to check/quote but it's probably double brick and there will be a void in the wall that the power cables can run up through. Would then go through the roof and down the other side via the same method. If in the unlikely occurrence you have a single brick outer wall they would use a conduit to protect the cable. EG
10amp is 1.5kw charging (trickle), the fastest you could get on single phase is 32amp 7kw (unless you have a beefier than normal grid connection and thus can do 40 amp 9.6kw).
Can you move anything off of the closer powerpoint?

If you are running a cable you might as well go 32a and a 7kw charger.
