Few days ago I started a discussion in Electric Cars public group on Facebook discussing few ideas on how to improve EV charging for electric car drivers. Today a user named stanislav Jaracs shared his idea on the subject which I quote below.
This is a never ending discussion and once in a while someone comes with an idea and claims that their found the ultimate solution for public EV charging. In my experience, there are two charging concepts:
2) wait to charge
The second one means L3, so that there is no problem of occupying the charging unit outside of charging regime.
The first one is where all the ambiguity happens. If you tell people that they have to re-park their car when it is charged or that they have to figure how/where to park & plug to make sure it will have sufficient SOC when they need it without offending someone else, they will figure it is better NOT to get electric car. So, who is killing the EV this time?
It is L2 charging that gives you full charge either way before you are ready to vacate the spot or not enough charge for the time you are willing to park. Then, we get various people coming at different times to the charging facility, these people have different charging and parking needs and this creates complex matrix that cannot be solved easily. This produces all the confusion and sense of unfairness.
Only if we cover every parking spot in the world with charging hardware, this anxiety will vanish. That would be a huge cost, though. Remember that your own garage is your most secure charging location - park&charge - and in many cases L1 charging suffices.
Editor's Noate: I wonder if wireless charging in public and private parking lots is the key to improvement? They are also known as plug-less charging.
