Well you have to keep it ON via its 12V power pin, but you remove Enable signal. So it will turn DC conversion off, but its logic will keep working.
ok, I have pins 4, 7, 8 powered but as soon as I turn off pin 4 I loose the aux voltage reading. It doesn't vanish, it just slowly drops towards 0. Can try again tomorrow. Is it not like that for you?
Hm, the charger does not fit in the exaust tunnel but it's HV output can still be permanently connected behind the contactors, or can't it? Even if that means extending HV cable? Just wondering if the charger is permanently connected and it's caps are always filled with voltage does that affect longevity of them?johu wrote: ↑Sat Sep 03, 2022 4:30 pm So first of all it turned out that the charger does NOT fit into the exhaust tunnel So now I did it the more traditional way, connected it to the DC junction box, rewired the contactors so they can be powered with the ignition off and programmed the VCU to do precharging and contactor closing in charge mode.
Hm.. i would need to inspect my wiring, but i think pin4 is the sense and pin7 is actual enable for DCDC. Also i figured if i connect charger supply pin8 together with DCDC sense pin aux voltage is less. Can you test? If true we have to correct wiki.
I have it permanently connected via 20A fuse in my Mazda. No issues to date. Either from charger or dcdc.m.art.y wrote: ↑Sat Sep 03, 2022 7:14 pm Hm, the charger does not fit in the exaust tunnel but it's HV output can still be permanently connected behind the contactors, or can't it?

I didn't want to pull permanent HV all the way from the back of the car to the front. It would have facilitated things, like not having to rewire contactors and not needing an extra DC-DC enable signal.m.art.y wrote: ↑Sat Sep 03, 2022 7:14 pm Hm, the charger does not fit in the exaust tunnel but it's HV output can still be permanently connected behind the contactors, or can't it?

This is kind of a known problem with Leafs, moisture gets into the sense pins at the back of the Chademo port, it usually starts working again when moisture is cleaned off the contacts, perhaps some sealant would help or other method to prevent water from getting in.johu wrote: ↑Sat Oct 01, 2022 5:29 pm Well it wasn't. For the first time it was raining heavily which may have been part of the problem. The first charger, a Veefil, reported communication error 122. There were two more chargers just 200m away. They also faulted out within a second of connecting to the car. So I broke out rich man's again and charged at 12 kW for a while until it overheated. At least we had reached 50% by then. Rich man's uses the CHAdeMO port as well, so why was it working but not the regular chargers? Before me a Nissan Leaf had charged successfully. I never found out but we did decide to leave and retry our luck at Metz. To my surprise it was now working again.
Yes, absolutely. Also the brakes are about due for a final change (they are still the disks and pads from when I bought the car 4 years ago with 40000km less on the clock).Boxster EV wrote: ↑Mon Oct 03, 2022 6:20 am Sounds like a lot of drama for one trip - keeps it interesting!
Time for some preventative maintenance on all wheel bearings?
