Why can I get 7p per kWh to charge my EV with Charge Anytime add on, but nothing similar for my home energy battery?

Hi,

Sounds like your home storage batteries get charged by something like Economy 7. But EVs on the 10p/kWh rate get Charge Anytime which charges them whenever the grid is green and has spare eco juice available. That might help explain things a bit.

Thanks yes.    they are on economy 7 but my solar inverter has the ability to manage the grid,  the battery management and solar charging management and will divert any excess electric after charging batteries, house usage etc to the hot water tank, remotely so Ovo could update and control when to charge the batteries etc for green excess in the grid. just like the car system……. if not The app for the system has a fast 1 hr over ride charge period they could send a automated text  and I could push the button on the app (this could easily bee check on the meter reading to match the time text sent and time of increased use!) and charging price changed to the 10p

It is because OVO can choose when exactly and by how much to charge the EV. So can pick the cheapest 30min slots while making sure the EV is charged as per the customer request. 

With E7 or Octopus Go for example the customer gets to choose when you charge and by how much. 

Overtime i suspect all the cheapest tariff will be based on Energy Suppliers having some control. Hence Intelligent Octopus is cheaper than Octopus Go. 

I suspect OVO Anytime may naturally evolve to cover some home batteries, if the batteries have suitable control systems.

I have nothing to prove this, but also suppliers often launch new products with cheaper rates (Octopus were open about this with early Octopus Go rates for example). 10p is quite a punchy rate from OVO. The more people who sign up, potentially the more difficult it may be to retain that rate. We will reach a steady state at some point i suspect where the price difference between peak and off peak may change as more and more EVs are on the road. 

But shorley that only works if the car is in a or its charging point! my batteries don't have wheels so can be controlled 24/7/365 which I would think are more reliable to use as a excess power store than hoping some ones car is plugged into there charger or did I miss something else! sorry if I seem thick

The battery charging preference rate only happens when the car is plugged into the charging point at home. I understand the point about home battery storage but at present - as has been said - the system controls when the car is charged based on grid availability (it actually costs less at some times of day for the energy companies to draw power from the grid).

Perhaps ask?

Post what they say? 

thanks I can understand that but the electric car when pluged in can revers charge to run the house at any time so the car is charged at 10p rate any time ovo decide to swithc to the 10prate and then feeding that back into the house from the car battery so the house is running on 10p a unit and not the Peakrate or offpeak rate ? which the rest of us are paying!….

as for building a control system if my 5 year old Phone can switch on and of the Inverter and control its outputs  with a 15second delay  from pressing the over ride / Boost button then a multi million pound computer should be a pice of cake for it

The flaw in your argument is that you're only thinking about your setup. OVO isn't making decisions based on a single customer. They're looking at products they can offer to thousands of customers.

Another flaw in your argument is that OVO doesn’t have a single giant multi-million pound “computer”. They use a lot of different systems, services, platforms and infrastructure as demonstrated by the OVO Tech Radar. You can’t just chuck any old random code onto that stuff and expect it to work - because it won’t.
