Vehicle to Grid – How Electric Vehicles Interact With a Smart Power Electricity Network

What is Vehicle to Grid
Also called Vehicle 2 Grid or V2G, Vehicle to Grid is the process of http://5e3e.com/ connecting your electric car into the transmission electricity network. If you have an electric vehicle then you will definitely want to consider setting up V2G through a simple metering system and contract with your local electricity supplier.

What do I need to consider before deciding to connect my vehicle to the grid?

  • Firstly you have to have an electric car which can be charged by a standard electricity outlet.
  • The second thing you will want to do is determine some basic driving habits – i.e. if you drive almost your entire vehicle range to work and back every day, then there is unlikely to be much energy left over to swap between your battery and the grid, which makes setting up V2G a little redundant
  • Having decided that V2G connectivity is possible and feasible, you will need to look at the right products on the market to help you achieve this. I.e. which inverter should be used and which electricity trading contract will suit your needs the best?
  • If you decide suddenly that V2G is not good for you, how can you get out of an otherwise more expensive contract?

 

Once these basic items have been checked off the list, it is time to call up your utility and start the process of applying for V2G. You can then purchase a suitable inverter which allows you to feed back into the grid (this will be similar if not identical to the type of inverters used on solar PV grid connected power supplies). Of course you will have to decide what sized inverter to go for.

For example, a 5kW inverter may cost $1000 and a 2kW inverter may cost $600. Therefore you have to be sure that you can recover the $400 over being able to sell a higher rate of electricity in peak times. Some simple maths will help you work out the optimal solution, but just be aware of the various pay offs for each option.
