Charging At Home vs On The Go vs Battery Swaps

If electric vehicle, EV drivers are to have a choice, we should all have home electric charging units, recharging stations in conveniently located public places and battery swaps stations.

The gist is that the more choice there is, the more vibrant the economy is, the happier people are.  In an ideal world, tomorrow’s EV drivers will be able to charge at home through a powerful 380V electric charging stations, would be able to drive anywhere and park in front of a public electric charging station and be able to go to battery swapping stations when needed.  How likely is all this?  Depending on how serious is the current economic crisis and how lasting the changes are, it’s hard to say yet.  However…

Charging At Home.  Obviously the solution most drivers will want to have is to conveniently charge at home.  It makes the most economical sense.  However, not everyone can do that, especially is they park on the streets.  Charging at home will mean having an industrial 220V or better yet, 380V electric line into your home which will cut down the charge time by half and even third.  Add to this the benefits of those who have renewable electric sources, solar panels, wind turbines, etc and the economic benefits become very advantageous.  But what about those one the streets?

Charging Anywhere, On The Go.  Obviously the unspoken battleground here is who will conquer the market for electric recharging stations on the streets.  Hopefully no one will, leaving choice and competition to boost our sagging economies.  Coulomb Technologies has a head start with some pilots projects in cities.  We met them and found them genuine.  Other players in the field are Better Place.  Better Place has a more in-depth vision that also includes leasing batteries and swapping them.  Another less spoken of contender would obviously be utilities that are quietly studying pilot projects.  However, they also have to contend with an aging grid that desperately needs upgrades and funds.

Battery Swapping Stations.  That leaves us with battery swapping stations, much heralded by Better Place.  Ideally, an EV driver would go long distances, see the energy level low, drive into a battery swap place and get a fresh battery pack.  The idea sounds ground but many questions need to be answered.  For one thing, we all know how poor lithium-ion, Li-io life span is.  So what quality control would there be to ensure fresh Li-io batteries are in place and not over-used ones, for instance?

Ideally, all these solutions could play a great role in making the future of the electric drive completely realistic.  We hope that greed won’t make all the dominoes fall down again and that choice will be available to keep everyone happy by offering more added service and products.
