Advice on EV tariff with 2 EVs

silvercar

My estimated usage for electricity in a year is:

3000 KWH house
1800 car 1
600 car 2.

Total 5400 KWH.

At the moment we have a tariff through OVO that discounts the car 1 use down to 9p/ KWH. Car 2 is of the type that can't pass over control to a 3rd party and so charge is at full price for that one. (The difference in usage is because of the tariff situation we deliberately use car 1 whenever possible.) Moving usage to the middle of the night isn't something we do.

The tariff at the moment discounts the car 1 charging without adding any increase to the daytime tariff, which was the reason we have kept to it up to now. It is galling to pay full rate for car 2, so I wondered if anyone had any better ideas on tariffs.

Intelligent Octopus. So long as you have a compatible wall box to link to your account, rather than either of the cars. 
Price just reduced to 7p

We have 2 EV's & Ohme Home Pro. Neither of the cars are linked to wall box for charge limits. I do it all manually.

Our charger is a podpoint, I don’t think that is compatible, though I guess the Tesla may be. Would still leave car 2 at full price and the standard rate is higher than the price cap I believe.

pretty sure it's
Ohme, Zappi & wallbox. Could always ring & ask about pod point.

2nd car in 11:30 to 05:30 & Tesla in daytime if you get the intelligent part. Personally never had a issue getting daytime charges @ off peak rates.

There’s also Octopus Go which is tech agnostic. They’ve just upped it to a 5hr window and dropped the rate to 8.5p/kWh

Thanks. Worth looking at Octopus it seems. Is the standard rate higher than the price cap? The beauty of the current set up is that day time rate is at the price cap, and we are heavy users. So even though it is frustrating charging car 2 at the price cap, I need to balance that against all my day time units being at the price cap rather than higher.

Eon Next Drive 7hr window at 6.9p per kWh

Just use the Tesla with the Intelligent Octopus Go integration and charge EV 2 at 11:30pm. And do use the cheap overnight electricity for things like the dishwasher etc.

This applies to your entire house so you could be charging one car with the 7 kW charger (that I presume you have) whilst simultaneously charging the other car more slowly with a "granny charger" at 2.35 kW.

Yes, we have a 7Kwh podpoint charger. Always worried about fusing the whole house if I draw so much for so long, I know in theory it’s fine.

As long as your house fuse is sufficient, you should be fine.  When our podpoint was installed, the pre-installation visit required us to upgrade it from 60 to 100amp before they would install it.      We charge on the podpoint whilst the dishwasher is on at cheap rate and more importantly, the 30amp AGA.  Plus, we are going to get some batteries installed to charge overnight.

We haven't gone to a car tariff as the AGA needs the 7 hours and 4 or 5 hours isn't enough.
