Hehe, it's the high energy density stuff, not the high C-rate stuff. Anyway, I think the motor/controller is the limiting factor. It lights up the tyres in 2nd pretty well, but pretty docile really.

Re: 1988 Honda Prelude conversion - fastest build log ever.

I did a slightly longer drive today - 95 km, but most of it was at 70-90 km/h with the odd stretch at 100. It seems to pull 18 kW at highways speeds, which is pretty good for a conversion I think. 8 kW - 60 km/h 10 kW - 70 km/h 13 kW - 80 km/h 17 kW - 90 km/h 19 kW - 100 km/h Although this is on fai...

Re: 1988 Honda Prelude conversion - fastest build log ever.

That would have made the cost lower, but they simply wouldn't fit. This was a bit of a no-compromise car - all 4 seats were retained, only 100 kg over the original tare, and (almost) all boot space retained. No way Tesla modules would fit, and Leaf modules would offer half the energy for the same sp...

Re: Wife's ebike conversion works great!

She'll love it. My wife loved her ebikes to bits. Unfortunately now we live in a nice affordable part of Perth, we have to use motorised transport to get around, so the electric scooter gets a workout.
Well done :)

Re: Can EVs survive without subsidies ?

Bust out your calculator Hillhater. Australia buys about 100,000 new cars per year. At $25,000 each, on average, that's about $17,000 straight to the manufacturer per sale. We import all new cars here. So call that $1.7 billion per year heading off shore in exchange for new cars. If they were EVs wh...

Coupled with a sustained period of de-growth, we can most certainly change the way we generate our electricity and manufacture our goods, all the while reducing the burden we are putting on the very systems which sustain us.

Biofuels are epically inefficient use of resources. Take 10 MJ of energy and productive land to produce 8 MJ of fuel, and proceed to throw 6 MJ away.

Has anyone here in the e-bike manufacturing world bought an ultrasonic wirebonder for terminating cells? It's a big ticket expense, so I'm expecting to only hear from larger e-bike manufacturers, but the company I work for is looking at buying one with a working area of about 500 x 900 mm. I'm guess...

Yeah, we at the AEVA maintain friendly relations with Nissan - we don't publicly shame them or tell people not to buy their cars, but we also don't shy away from the fact these cars don't have thermal management, and will therefore degrade faster than a battery which does.

There was another car who had a fire too - they were able to jettison the pack so it didn't burn the remainder of the vehicle. Wise strategy.

Re: Grid tie inverters and HV battery

These units check maximum Amps available from the solar array. With batteries connected they tend to blow if you are not limiting Amps during such check. Also a Precharge is helpful to keep them alive. Cheers - I've since heard that it can, and has been done, but it will export power at the maximum...
