We had some interesting discussion at a recent GHEVA meeting about where public accessible chargers should be located and whether 240 V chargers are needed or regular 110 V outlets could work.
I have commented before that GO transit is installing ChargePoint charging stations in their parking garages. If you use the GO train as part of your daily commute to work, then you are likely going to be leaving your car for 9 hours or more and for most EV drivers, that is much more time than you need to fully charge your vehicle. In my smart ED, for example, 9 hours plugged in to a standard 110 V outlet provides about 60% of the battery charge. The other challenge at the GO station is that there are only a couple of chargers and if you're the third car to arrive, you're out of luck.
But what if the choice was a 110 V outlet for those 'longer-term' stays? For most of us, that would provide sufficient charge to get us back home at the end of the day and even make a few detours along the way. Plugging in to a 110 V outlet will keep the battery warmed up and that also helps performance in cold weather.
Now I am not an electrical engineer but I suspect that there are still infrastructure considerations to ensure that the outlets are wired correctly and that systems don't get overloaded so it's not as simple as adding more 110 V outlets along the wall. But a larger number of 110 V outlets in places where people are primarily going to park for longer terms seems to make good sense and probably at no greater cost than a couple of higher-speed chargers.
