The Anonymous Widower

The Combined Car Park And Storage Battery

I don’t drive these days, but I did for well over forty years.

If I was still driving now and still lived in Suffolk, I’d be looking seriously at an electric car as an everyday runabout, as rarely in the last twenty years, have I had the need to do a long journey, that I couldn’t do by train.

So my electric car would probably sit in a car park space at Cambridge North station, attached to a charger, a lot of the time. But with better batteries and vehicle-to-grid systems, there will come a time, when you will park your battery vehicle and tell it you’ll be returning in a few hours or days and you’ll need say four hours of charge on return. Obviously, if your circumstances change, you will have an app on your phone to make adjustments.

Suppose your average car had a 30 kWh battery, this would mean that the 450 space car park at Cambridge North station, if say 300 spaces were for electric cars would have a electricity storage capacity of around 0.9MWh.

So if the wind wasn’t blowing or the sun wasn’t shining, then there’s probably about half a MWh of electricity that can be borrowed and still allow drivers to get home.

It may all sound terribly complicated, but electricity put into batteries at night or other quiet times, gets used when it’s needed.

Batteries and other forms of energy storage will be everywhere; in houses, offices, public buildings, wind and solar farms, and in every electric vehicle.

There are 31.,6million cars alone in the UK and how many are quietly sitting in car parks and garages or at the side of the street, for most of the day.

The Car Park As A Power Station

There will be multi-story car-parks reserved for electric cars.

  • Each parking space will have a charging point.
  • The roof will of course have solar panels.
  • I would expect that in a few years time the connection between car and charger will be automatic.
  • The parking charge would be based on a mixture of time parked and energy passed to or from the battery.
  • Car parks would probably also be paid by National Grid dependent on how much energy they can make available automatically.

The control system for all this lot, would do my head in! But it would mean that all generated energy was either used or stored!

In some ways a car pack for electric cars would become a small power station.

Examples Of Car Parks

These car-parks would have some interesting applications.

Airports

Airports like Heathrow have a pollution problem and it’s not just the planes, but masses of diesel and petrol vehicles.

  • To encourage more passengers to drive electric vehicles to an airport, why not make the closest car parks electric car only?
  • Long-term car parks for electric vehicles could be a massive storage battery, which would be used to help power the airport.
  • Car parks for electric cars would be less polluted.
  • Car parks for electric cars could be under the ground with runways and taxiways on top.

Everyone would be a winner.

  • Passengers’ electric cars would be earning an energy storage charge from the National Grid.
  • The Airport would have a reliable back-up power source.
  • There would be much less pollution at the Airport.
  • National Grid would gain additional much-needed energy storage.

There will be a lot of thought going in to making airport parking more efficient and affordable for electric cars.

Business Parks And Offices

Much of the logic for airports would apply.

But I do feel, that companies with medium and large-sized fleets of vehicles will go electric, as they can then integrate energy management across their premises and fleet.

Town And City Centres

Towns and cities with a pollution problem like London, will surely use the best car parks as bribes to get more electric vehicles into the centre.

Residential Developments

The mind boggles at what could be done in residential developments.

  • Cars could go to and from parking automatically.
  • Every house would come with energy storage plus that in the car.
  • The development would appear car-free.
  • Cars could be in shared ownership with the development.
  • There could be automatic trolleys running through the development delivering parcels.

The market will determine what is needed.

Conclusion

Creating car parks solely for electric cars will create energy storage units at points of employment, living, shopping and transport.
