We discussed it several years ago at police and industry liaison security meetings and it was a topic that had been brought up for consideration at least 10 years ago. The main sticking points from the police and insurance sides were security and battery traceability. If the battery packs were that easy to change, at current values, unless they could be rendered traceable and identifiable in a way that could not be compromised by thieves, with a secure centralised traceability scheme that could attribute a specific battery pack to an individual vehicle in the same way that an engine is currently traceable; cars would be being stolen, jacked up or turned on their sides in the street to relieve them of their battery packs in the same way that catalytic converters and sometimes, lights, doors and other body panels etc. are stolen from parked vehicles now, but at much greater profit to the criminal and far greater cost to the industry as a whole.I have been giving this some thought..
Until such time as the technology reached the stage where we can drive 200(ish) miles, then recharge sufficient to do another 200 miles in a max of 15 minutes electric vehicles are unlikely to be a viable contender to an ICE ..
My idea, as muted some 6 years ago, of having standardised batteries that are swapped out automatically at 'gas stations' has to my knowledge never even been looked at
You pull into the garage over a pad. Pad slides away and the flat battery hooked out to be replaced with a charged unit
Flat battery automatically gets shunted off to be charged..
Using that method would negate the issue of cars being valueless after 8 years or so, would negate the issue of 'can I get there without having to stop for an hour or so' AND would lead to a standardised cost and the ability for garages to make profit in much the same was as they do with fuel
I don't know what stage it might have progressed to now, if at all, as I retired and have been out of the loop for over 2 years. Getting competing manufacturers to agree on a standardised battery pack when they are all trying to gain the upper hand with development of competing technologies is another big problem that would probably need legislation to resolve.
