quick charging at home

[Glasgowrob]

seriously considering looking at an EV as a taxi for our airport transfer business

the only issue i have is that there will be times i need to charge from empty to full in a short space of time at home.




following on from the thread on here about 3phase i understand that some of the model S' come with dual chargers??? not something i've ever heard of before, anyone enlighten me on this? i presume its just 2 cables plugged in and hey presto charging at 14kw

ideally i'd be looking to turn around a car from near empty on occasion to full in 5/6 hours is that doable for something like a 85/90/100 ?

Do-able on any of those models with 3 phase and a 22kw charger.

Podpoint do a 22kw unit for £1k after the OLEV grant but I'm sure costs will add up significantly if work is also required to upgrade your electrics.

I'm sure someone will be along shortly with some figures for you.

If you already have 3 phase you're looking at a £500-£1000 charger install. That's it. It's just one cable. The car deals with the charging.

If you don't have 3 phase an upgrade costs from about £800. Depends on what needs doing.

You need 3 phase power supply and charger to achieve anything more than 7KW charging.

Tesla changed the charging spec of their cars regularly.

Our 2017 build X will charge at 16.5KW on 3 phase, we didn't spec 'dual' charger, and 16.5KW is now standard I believe.

2016 Model S had options to be fitted with 'dual chargers', which will do 22KW.

Model 3 will do 11KW on 3 phase.

The Tesla wall charger will work off 3 phase, around £500, and I believe you can have multiple units installed at one address with no issues. Again to hit any of the above charging speeds you need a 3 phase power supply + charger.

Ive head of folks being charged 5k to upgrade to 3ph, yes they needed a transformer upgrade to do so but the chance is there that it could be a steep fee.

I know your in a difficult position as you don't know what or where yet. have you thought of a 3ph generator if your not planning on using it often ?

I seem to recall some taxi companies got DC rapid chargers installed. The older 50kW units are probably available used for not too much money these days, but of course you need a hefty grid connection that is probably £££££.

I always tell people not to dismiss 3phase being installed. If the capacity is there you can have it for the price of the cable being run to your door. This costs just £900.

The prices only become crazy if you're far away from the street... but you're allowed to dig your own trench. You're allowed to do all the work yourself and have them just come connect the cable.

These quotes of £25k etc. are just the electricity board quoting them doing EVERYTHING and that means 5 guys sitting in a transit crew cab pickup reading the sun while one other guy does the actual work and somehow takes a week to dig a hole.
