A quick update on the car front.
I had my first breakdown the other week. I went to drive away in the morning and everything was just dead. Turned out the 12v battery we use to power the control side had gone flat, and oddly enough a couple of fuses were blown. As you can see from the picture, I got the youngest member of the team on the job, with my own personal favourite ‘spanner’…. 🙂
And when we’d finished fooling around we called Bob and he came down and fixed it. No big drama but some useful ‘operational experience’.
Actually things have kind of ground to a halt on the Nemesis. It’s been with me since August, for what was meant to be a months worth of road testing while the Battery Management System (BMS) was finished. Three months later I’ve still got the car and we’ve not got a BMS yet. Which is disappointing to say the least. Everything else about the project has gone incredibly well, but for this – and it’s held us up for over six months now. It’s a frustration for all of us, not just me.
The car goes – it goes like hell, it’s just not ‘plug and play’ – by which I mean I can’t just plug it in to charge it. It takes a laptop and some close attention and we’re not able to charge to the full potential of the cells (for safety). So it’s “close but no cigar”.
But we are entering the end game, a BMS is in sight, almost. And we’ve planned the final pieces of work to finish the car – tweaks to the suspension and body, interior decor, paint job and so on – and we’ll do all of this at the same time as the BMS gets fitted. It’s probably 4 to 6 weeks work from the time I take the car back to the team, which I hope will be any day now.
And then the Nemesis will be fully functional, properly plug and play (and with a fast charger I hope) and capable of it’s maximum performance – which we’ve not had out of it yet (incredibly).
I expect we’ll post episode 12 of 6 in January, including (I hope) a revisit to Snetterton where we’ll be trying for a 1 minute 15 second lap – this is the goal we’ve been set by somebody interested in starting an EV racing series. Such a lap time would convince him it’s a serious proposition (range isn’t such a big deal apparently…) I’ve no doubt that if a petrol driven car can lap at such speeds we’ll have no trouble matching it. Won’t be me at the wheel though… 🙂
On another front, we know our friends at Lotus keep a keen eye on our progress and it seems like they like what they see – so much so that they’ve created their very own, limited edition, matt black version of the Exige – named ‘The Dark’ (or ‘Stealth’ in Japan). How’s that saying go – about the sincerest form of flattery? 🙂
That’s the latest on the car front. BMS breakthrough any day now… Followed by rapid completion and a resumption of testing and the fun part.
