Re: BATHOT, no fans running... what to do?

What temperature is being reported (kill switch in off position and right brake displays battery temp in dash) Most likely the temp sensors got wet. They're pretty unreliable anyway. The only fan is on the motor controller. The battery fans get removed to make space for the larger lithium batteries....

Re: questions regarding rewinding and stator insulation

each winding wire also needs to be insulated relative to all the other turns of the same winding and that of other windings. given that you will likely be increasing the voltage differential between turns due to a higher operating rpm, you will likely need more insulation on the wire Yes, I would b...

Re: Notes on my commute.

I had a look at mine couldn't find a brand but I took some photos. I think that because it different bms and charger, it also needed a power supply to run the light. Not sure but there is no reason it wouldn't run off the standard wiring. Thats what they do in cars.... It's probably a powersupply i...

Re: Repurposing hybrid batteries for a full BEV

Most of mine the capacity is okay, but the difference in self discharge is not. that's mainly why they're not usable in a hybrid and sitting in my shed

I haven't capacity tested in a long time.

If you're local I'm happy to just give them to you

Re: Repurposing hybrid batteries for a full BEV

I do have heaps of nimh 7.2v 6.5Ah sticks from nhw10 prius. They're all 25years old though

with nimh, putting them in parrallel is difficult as their voltage drops as they approach full charge.

I'm based in WA, and the sticks are easy enough to ship

Re: Hypermiling in a Model 3

I’m not sure how you get great economy in a hybrid if you spend most of your time on long country driving (using the petrol engine) such as we do. By using an atkins cycle engine instead of an Otto. Atkins cycle is significantly more efficient, but has far lower peak power. Most of the fuel economy...

Even real caps dry out after 10 - 15 years. Ceramics might get to 40 years, but they're far from energy dense

Re: lithium-sulfur batteries

Thundersky once put out a spec sheet for 600Ah lithium sulfur cells that weighed the same as current generation 200Ah lifepo4 cells. This was at least 6 years ago. They must not have got them to work, as it still has yet to enter production. It's the same old thing, until mere mortals can buy a batt...

Re: Interworking a Sunny Island with a Redflow Flow battery

But the three main issues for me in a static environment in the subtropics are cyclical degradation, heat derating and fire risk. So, as a thought experiment, what is the expected percentage deterioration for the various lithium chemistries when operating daily charge/discharge and operating in a 2...

Re: Interworking a Sunny Island with a Redflow Flow battery

My lifepo4 batteries turn 10 this year, still in daily use. Getting to 10 years isn't so hard now.

OP - compared to cost of a super cap, have you considered having a small buffer battery instead? 100Ah at 48v would cover it

The car should be interrupting the charge before the contactor opens. Contactors don't last long when switching under load

Re: Vectrix and assorted EV parts

where are you located Pete?
Best bet at the moment would be a 3.3kw TC Charger. They fit in place of the original.

Downside it ends up being around $1k, and you have to slow it down when not using a 15A powerpoint

What if the crumple zones are all internal? That way you only have to slow the deceleration of the passenger compartment rather than the whole vehicle.
