Economy 7 Charging for Hybrid Car ? Which Tariff/Supplier is cheapest for me ?

CaptainBeaky

Please could any one advise me the cheapest Economy 7 tariff to use to charge up our new Mitsubishi Hybrid car.

I am told by Mitsubishi UK it will use approx. 10kw of electricity over a 5 hour period to totally recharge its batteries.

We normally average about 9 kWh of electricity usage per day otherwise at this time of year.

Would I be correct in thinking that some Eco. 7 tariffs have a dearer day rate - if so will it be worth the trade off ?

Bung your details into one or more of the suggested comparison sites to find the best deal for you

Look at your current past annual energy use, and your current past annual mileage. Add together the predicted kW per annum needs of your lifestyle hours use of the car and home together, then put that figure into a comparison site. As a then heavy user pick the best two results from the mix of 8p to 40p per day for electricity standing charges and decide which you want to go with. At that point you can put the figures here and someone in the group will I'm sure check your analysis.

Afraid that won't work - petrol mileage will not be equalled by an EV, it will be less in most circumstances. My best deal is EDF Blue 2015 E7, it is a 32a Fast Chargepoint and I usually complete my charge between 0005 and 0355, but I still have reduced power cost until 0830.

Some offer dedicated EV tariffs but they are worse than EDF at TGIF moment for my area.

I appreciate that there are variations of Economy 7 timing - particularly in Scotland where you live. However it appears that you are getting 8 hours 25minutes of off-peak electricity - unless there is a break in your off-peak period


However the majority of E7 households have 7 continuous hours and most starting after 00:05 - particularly in summer.


In my area(Midlands) the notional timing is 00:30 - 07:30 in winter(GMT) and 01:30 - 08:30 in summer(BST).


In addition many of the older meters with a mechanical clock to switch from peak to off-peak are running slow. Mine for instance switches to off-peak at 01:50 to 08:50 in summer.

For me its, 01:00 to 08:00 in the Mungo Jerry-time

I will definately check this one out. Many thanks for the heads up.

On another note I have been warned by the Mitsuibishi Dealer to avoid using a fast charger to much as he said it "frys your batteries"

Rapid charging is also the most problematic way of charging a battery because it involves forcing current into the battery very quickly. The chemical process involved generates heat, and the faster the charge, the higher the concentration of heat that must be dealt with in a short period of time.

All charging creates wear and tear on a battery. The average electric-car battery can withstand about 5,000 charging cycles, but fast charging can put far more strain on a battery, lowering its life expectancy – and with electric-car batteries costing thousands of pounds, they aren't something that the average driver can afford to replace on a regular basis.

Perhaps the Nissan scheme for leasing the batteries might be a good idea.
