Everyone here is anxiously awaiting more public charging points as electric cars become more and more mainstream. It's probably the biggest factor facing the practicality of electric cars, in terms of the way people are used to using cars. Amid all the discussion of charging standards and Level 2/Level 3 type talk, one thing keeps popping into my brain; what type of security controls are being implemented for public charging? For example, I drive my electric car downtown to do some shopping, which happens to be on the upper limits of its practical range. I hook into a public charger (which most likely very soon won't be free), and leave, confident that my car will receive sufficient charge to get me home. Except upon my return, I notice that a prankster has unhooked the charging cable from my car! So now I do not have enough charge to get home, without hooking back up and waiting even longer! Seem far-fetched? Think about it; in this day and age when people with nothing better to do will create computer viruses to mess with the computers of people they don't even know, is it really that hard to envision such a scenario? There are people out there who will get their jollies out of messing with somebody with this type of shenanigans. What is the industry's plan for dealing with this?
