4. The advantage to the CEGB of all these EV's charging up over is that they will have access to a massive amount of stored energy to deal with peaks. They are VERY enthusiastic about this as they will no longer need to have 'peaker' coal fired generation plants on standby, which is costly and very inefficient.
Is this absolutely going to happen?
I've been banging on for years that this is the battery capacity that the national grid has craved but it has to be thought out and informing the public using EVs is vital. What if you hooked up an EV - the battery of which was half depleted - to the grid with the intention of topping the charge up to full for an intended journey and have just enough time for the charging. Returning to the car to find its battery in a worse state of charge than when connecting because the grid saw fit to use your battery to boil kettles and power TVs for an episode of Eastenders isn't going to work. By what method do you inform the grid of your energy requirements wrt to timeframe?
