Re: charging at work
I dont think HMRC will be interested if its a EV or a ICE vehicle the fact is the employer IS providing free transport to and from work for this worker. The company isn't paying for transport though - they're paying for fuel. Interestingly, it's not covered by the HMRC guidance on travel rates as t...

Re: VW EL1
Autocar have it on the front cover this week. They say that a limited production run may happen in a couple of years. Suggestions that ~£30k may be about right. I see no reason why a similar car could not be built as a kit car though. Take a Sevenesque chassis, a windscreen from a Stratos replica an...

Re: range extending generator
I've often pondered the idea too, but nothing to add of any use to you. Sorry! One thing I have hunted around for is more information on hydrogen conversions. I've found people suggesting that it should be possible in a similar manner to an LPG conversion but I've never found a place that would carr...

Re: Contactor-based Power Assist
Thanks for that. 342in-lbs (1.14*300A) is ~38Nm, and given the max RPM of 3600, that's a 3.75:1 ratio hooked up to the engine, bringing it down to just over 10Nm at the crank. That's an increase in torque of ~11.5% at the red line. I'm sure I'd notice the extra shove in the back, but I'm not sure wh...

Re: Contactor-based Power Assist
You've clearly illustrated the point that peak power is unimportant. The average power over the time you're at full throttle is most important and this is always over a much wider rev range. I too am doing sprints (but not hillclimbs) in the South West. I'll get some real data about engine revs and ...

Re: Contactor-based Power Assist
Hi Jeremy, I really appreciate the time you spend replying and the quality of your posts. Thanks for sparing the time. I tend to think in HP as it's the same, irrespective of speed, but you're right that torque at the wheels is the most important thing. My engine produces around 90Nm @13500rpm. The ...

Re: Contactor-based Power Assist
It's as I kind of expected, then. The specs did appear to be much betteer than anything else out there. Nothing else in that class really makes enough power to be worth using, so I guess my best bet is to go up to an ADC 6.7" motor, which I have seen in a 144v variant, that allegedly takes 550a...

Re: Contactor-based Power Assist
Hi Jeremy, Thanks for your reply - very detailed! Those Nano packs are significantly cheaper than the Polyquest ones and very similar performance on paper. I wasn't aware the Etek was no longer in production. I've been scouring specs from sites selling replicas. The specs I've seen say it's 10kg and...

Contactor-based Power Assist
I've been pondering adding an electric assist to my race car, probably for 2012. The idea is to use electric power alongside the ICE to boost power at full throttle. I want something nice and simple, so I was thinking about an Etek motor, which weighs 10KG and will take 96vdc @480A coupled to 25 Pol...

Re: New toy.........
A surprising (to me, at least...) number of die-hard petrol-heads like to deride electric traction One of the pseudo-complaints I often hear is the lack of a "soulful EXHAUST-NOTE"............ I have also read somewhere of a possible obligation on EV drivers to generate a continuous "...
