Sorry it’s been a few weeks since I posted anything on the car here, or anything at all on this site in fact, my bad – only excuse is there’s a lot going on. More of that next week I hope.
Meanwhile, on the car front:
The new lightweight rear end and rear diffusers are both fitted and fully functional.
The rear end is now stiffer, lighter and much easier to get on and off. Also we’ve got the new rear lights installed and wiring complete now as you can see from the picture. The back end of this car is def its best side.
The diffuser (the bit that wraps under the car at the back, with the number plate on) has its twin flaps, either side of the number plate, one for normal and one for fast charge connections.
Our guys have been working on something dubbed ‘the Lobster Claw’ which is a cable retract mechanism. Looks rather cool and is about 90% complete. Basically it allows you to pull a three pin plug (or whatever connection we choose) from the back of the car, pull out as much or as little cable as you need, plug in and when you’re done, snatch to retract – like a Hoover (or should I say Dyson these days).
That may sound easier than it is. The tricky bit is to have a cable that isn’t coiled around a drum, because that would get too hot if you left it partially coiled and ran big a current through it. With a drum approach you’d have to pull all the cable out whether you needed it or not.
So with all this work complete the car left Norfolk yesterday headed back up North for it’s final bits of electronic kit – the VCS or ECUs depending on who you talk to. Either way it’s the bit that connects the throttle pedal, the batteries, the BMS and the motors.
It’s a couple of weeks to fit and then a couple of weeks of shakedown testing and some road testing for the BMS at the same time.
Then the car is coming back to Norfolk for its full on track and road testing, followed by the paint job and that’s it. Several weeks later than I hoped for again, but we are getting there, actually making big strides in what has def turned out to be the hardest part of the whole project – the electronics.
Meanwhile we’re planning some ‘events’.
First is likely to be a crack at the UK land speed record for an EV, for that we’ll need to do 140 mph – should be within the ability of this car. The current record is held by Don Wales, grandson of the great Donald Campbell. Don came up to see me a few months ago and offered to help us with the record attempt, which is really cool of him – then he told me if we do get the record we might not hold it very long as he’s planning another run end of this summer – so it’s on….. 🙂
Next event on the drawing board is a run from John o’ Groats to Land’s End, in less than 24 hours if we can. Co-conspirator for this one is Robert Llewellyn (I think he’ll always be Kryton to me… 🙂 ). Our plan, roughly, is to charge at windfarms and other renewable generators as and where we can, but otherwise use ‘ecotricity’ supplied through the grid and blat down from John o’ Groats to LE just as fast as we can in a non stop (other than to charge) run. We’ll need a fast charger for this of course – that’s currently on our shopping list and proving to be quite tricky.
The aim of this one is to tackle the ‘range anxiety’ that currently exists with EVs. This is a classic British endurance run, no EV has tackled it yet (as far as I know) and it should open some eyes, and minds, we hope.
So that’s it – car a few more weeks away from completion and serious testing (and another video update) – and a couple of record attempts on the drawing board.
