Double Charging

So one if the ideas I toyed with for a while was converting an old Mk. 4 INter Acco to EV, which would be more a "Ha! Even these can be made EV!" kind of thing.

However to get any reasonable range, I'd be looking at 150-200+kWh of batteries, and all the chargers within range of me are 6.6kW

But out of curiosity, if you have a big battery, and it's a small charger, is it more polite to use both charging leads and be done in half the time, or use one charging lead and be there for longer?
So meeting in the middle, imagine I used a 175kWh battery:
  • 157.5kWh is required charge if I charge at 10%
  • At 6.6kW it would take 23.86 hours to charge
  • At 13.2kW it would take 11.93 hours
So essentially, I'd be done a lot faster if I needed a full charge at one of them.

I mean, I can't imagine this is much of an out there question, as for example the Rivian is coming soon and it's gonna be 180kWh and they're going to need a lot of Fast Chargers, especially if they get purchased as tow vehicles, considering they'll be 3rd or 4th in the class with towing.

Lots, maybe most, ac charge points now are 22kw or 43kw per connection.

Even in this instance, with 150kwh, using both would be useful.

I'd suggest use both, but have the 2nd one able to be unplugged, with a note saying so.
That way you get the best of both worlds

Of course with an Acco parked in front, its possible noone can reach the other charger anyway.

True, they are large
