Charging Your EV
NO ONE PUTS PETROL IN SLOWLY !
Many EVs can not fast charge.
How quickly you can poor the "petrol" in is now the question that will guide your choice of vehicle.
Realy slow - 8 hrs 2.4 kWh 10A ( house hold 13A plug )
Slow - 6 hrs 3.8 kWh 16A ( home wall charger and shops )
Med - 3 hrs 6.6 kWh ( home and shops )
Fast - 30 mins 50 kWh ( Motor way network Ecotricity and Tesla )
Really fast - 10 mins 200kWh ( only Tesla experimental so far )
So if you're a painter and decorator you plug your van in over night and never leave your local city then slow 2.4 or 3.8 kWh charging is fine for you.
If you are delivering stuff city to city at some point during the day you will need a top up. Then you're going to need a 50kWh fast charge capability this in reality in the UK will be on a motorway service station at an ECOTRICITY PUMP sitting in your van with your sandwich, flask of tea, heater on, radio on, watching your battery percentage go up.
We are so used to getting 300 miles worth of fuel in under 10mins that having to wait does not compute.
The only equivalent as the moment is Tesla's 200kWh experimental charging system. Elton Musk is way ahead of the game as usual.
Wall charging units are £179 installed with a grant or £700 without. The government will knock a good chunk off the install price. The installer will not install it until you have the vehicle, for two reasons -
Your charger will charge at 3.8 -7.2 kWh but this depends more on the vehicle than the charger e.g. I have a 7.2 kWh charger, my ZE however will only charge at 3.8 kWh. For over night charging it doesn't make much difference to you as long as its full in the morning.
An hour top up at lunch time could give you 16 or 32 miles with 3.8kWh and 7.2kWh respectively .
Using the manufacturers lead
Running an extension lead through the window every night and trying to keep the rain off, then winding it up and putting it back in the your vehicle every morning will soon grow tiresome. Much easier to have a wall unit installed.
The public charging network is getting better all the time of which the Ecotricity network is by far the most together but for charging out and about I wouldn't rely on 13A sockets at shopping centres. They are usually out of order or I.C.E ed (Internal Combustion Engined) parked up by stupid inconsiderate "smoker" driver's.
Where to charge ?
- Charging will 98% of the time be at home but if you need a bit extra charging, at work is by far the most practical for the following reasons -
- NO DETOURS -
- NO WAITING - just plugin and start work -
- NO COST - although out of politeness you ought to offer a couple of £'s or a discount on your customers bill.
