Secret Scotland

If it's secret, and in Scotland…

Pop-up electric vehicle chargers – not looking good (so far)

I recently came across a news article heralding the arrival of a pop-up street charger scheme to be trialled in Dundee: I hope these ‘Pop-up Electric Charge’ people realise Dundee is in SCOTLAND!

While I wasn’t being negative, at the time I couldn’t lay hands on any illustrations of the proposed chargers, so didn’t know how practical they were for use in Scotland’s cold/wet/freezing climate.

From tech ‘toys’ I’ve built and installed out of doors, rain, frost, and freezing rainwater (plus snow) all combine to ruin anything designed on the bench and which works well in warm and dry conditions – only to be wrecked when place outside. Even just left outside in a sheltered position can see items deteriorate if not made of appropriate materials. Sunlight destroys plastics not designed for constant UV exposure, and condensation plus high humidity and freezing conditions can lead to ice formation, and destruction of items where water can collect in small spaces, and expand repeatedly.

I found a US article taking a look at the idea, and they did have an illustrative pic – I’m afraid things look good for dry and warm places, but Scotland?

I tried a quick search on that name. While it brought up many hits, none of them linked to this concept, and I gave up.

Unless they change the design, or make something with greater water/weatherproofing – which would probably mean increased complexity, and ongoing maintenance needs to keep seals etc functional – I don’t really this is appropriate.

Far better to go with suggestions to utilise existing street furniture such as lampposts, distribution boxes, and other item already found on the footpath, and which avoid trailing cables.

I’d suggest another option – a sealed post hinged at its base, lying flat, which rotates 90 degrees to stand vertical.

This provides a lever effect to help break frozen rain/snow, and with no sliding elements can be sealed.

However, I remain practical and aware of lawsuits – and suspect something would have to be done with regard to the hole left behind when it is raised. Unfortunately, a simple hinged cover isn’t really the answer, as it could freeze shut. A little though does suggest it can be dealt with though.

Well, we’ll see.

It might last longer than…
