RE: Polar Network - Source London Confusion
Just MHO .. I think the whole idea of public charging is ill-conceived. You can never demand to rely on them, the 'refuelling' time is too long to expect the point is unoccupied, the equipment may be damaged, or may damage your charging point or lead costing $mega and meaning your car is out of action because the point had a defective pin/receptacle that has damaged your charging port. I've tried it a couple of times and gone off the whole idea of public charging.
I'm also quite concerned about the vulnerability of the Fluence's charging position too, which is 'very sticky-out' and vulnerable to knocks and damage from careless passers by, and any such knocks and damage may render the port in need of repair. I get jumpy when visitors walk up our own driveway (!) when the car is on charge, in case they knock the lead.
If I can't make the round trip to a charging point under my [or host's] control I take an ICE.
For an 88 mile return trip, though, I would happily take my Fluence and simply drive in a manner to achieve that mileage. It shouldn't be a problem. Easier to drive in a saintly manner and use minimum juice to avoid using a public charger at all, than to blast to the destination simply in the expectation of getting a charge.
I do not believe public charging will be something for BEVs future. It will be through bigger and replaceable battery packs. There's just not enough commercial interest yet to justify the grander ideas for charging (the optimum is on-road charging) so at the moment we have this primitive 'plug-in' period of EV's evolution. At the very least, it will have to evolve into inductive charging under every parking spot.
