Re: One mean rally ready Hyundai Kona EV

If it also supports dynamic 4-wheel regenerative braking, that is also some mean software!

Not sure about the ground clearance for a rally car, though.

Re: Aftermarket iMiEV battery upgrade project

It's still not totally clear whether we will want/need to adjust the spoofing in the final design. It's looking to me that we might.
Perhaps there is a case (pardon the pun) for a programmable spoofer, accessible via the CAN bus from outside...

Re: Aftermarket iMiEV battery upgrade project

Mike, how is the spoofing progressing? That box you showed on the previous page - where does it connect? Does it connect to the swamp of intelligence under the rear seat? Or does it hang out from under the dashboard? I'm assuming you don't have to drop the battery out to make adjustments to the spoo...

Re: Nuggetgalore's iMiEV charger failure

OK, here goes. Pic from CRO screen, both traces 200 V/div, 0 V on centre line. Note yellow trace swinging down to -560 V while blue trace is flying up to +280. a difference of 840 V. The ringing is at a frequency of about 2.2 MHz. If that is the resonance of the 4400 pF caps and stray inductance, it...

Re: Nuggetgalore's iMiEV charger failure

Well, my high-voltage CRO probes finally arrived yesterday, so I was able to open up the OBC and measure the voltage across the capacitors. I can't measure across the capacitors directly, as I can't safely get a couple of CRO probes in there with the upper PCB in place, so I measured the voltage acr...

I'm sure I'm telling you nothing you haven't already calculated, but... I would be careful about "desensitising" the current sensing. The current sensor is probably also used to limit the current if Leadfoot Leroy floors the pedal on a steep hill or driveway. If the indicated current is lower, you r...

Re: Nuggetgalore's iMiEV charger failure

Well, the manual says "press the button at least ten times within the first seven seconds". It has no effect here, the pump does not run. Chris said earlier "don't worry about it", so I bit the bullet and left it in charge mode, with more coolant and funnel ready. When the pump turned on some ten mi...

Re: Nuggetgalore's iMiEV charger failure

I'm not worried about the pump, I'm worried that there could be large areas of the coolant circuit that are empty and I won't be confident until I see it circulating, sans bubbles. The Russian manual gives a thorough description of how to bleed the circuit, but it depends on using an "ASC" switch, w...

Re: Nuggetgalore's iMiEV charger failure

Urgent need to get the car going again, so I installed the 2200 pF/4 kV caps instead of waiting any longer for the 1000 pF/3 kV. Car now comes up Ready and the charger works, but the coolant motor won't run, so I daren't run it for more than a few seconds. I remember at one stage when the OBC was re...

Heh. I found the plug (opposite the inlet hose from the inverter) and tried to remove it with a 6 mm Allen key. Nothing doing. Having broken an Allen key many years ago in the same circumstances (and still wearing the scar), I abandoned the attempt. The plug and the inlet hose are at the same level ...

I would suggest that no thickness of paint that you can apply will last under vibration. Better go for a solid insulator.

Funny. I was sent them (at no cost) by the NSW Government and told I had to affix them to the car or else I would burn in the fires of hell.

I've since seen quite a lot of them on cars that I did not realise were hybrids.
