Yes. I park my Leaf in a carport just outside my bedroom, and can easily see the charge status from my bedroom or the adjacent office. That's really handy for me.

Re: Older Leaf driving impression (good value)

Leaf question: are those bars on the Leaf display a good enough indicator of capacity, or should one get Leaf Spy? The bars are pretty good; just don't put too much credence on the Guess-O-meter (distance to empty figure). Later Leafs have an actual SOC%, I wish mine had that. LeafSpy is good for g...

Re: Older Leaf driving impression (good value)

The J1772 port does not respond to trigger press to shut off the EVVSE, have to just pull out (scares me) You might have gotten that from me; I was wrong. They do respond to the trigger press; it's just that nothing visible happens. If you check the AC current or charge current with LeafSpy, it doe...

Re: Hack DC charging - limit to 30kW

Actually doing that though would require an ECU modder who was willing to reverse engineer the firmware in the BMU - not an easy task I would think! I have tried to do that. I have had no success getting to the BMS master firmware; I've had limited success reverse engineering the CMU firmware. I'm ...

Re: Fuse Internal Element Views

On the PEC drawing there is a call-out for item 7, a small dot or blob of a tin alloy (solder?), which can be seen below. ... so this must be some secret sauce for making fuses. From the end of this page : "Another slow blow fuse is the "M" type (named for the inventor). This has a s...

Re: eeprom readout for CMU Board

i noticed some possible ascii text string buried in here. It doesn't look like a VIN, but looks something like a mitsubishi part number, " 9? 94 A9 97 5? Z?". [For example, the label on BMU has part number 9499B116, and on the 8-cell CMU has 9499A794 with a serial number.] I note that if ...

No idea.

But if there IS a cutoff date, that might tell us that they (think they) have fixed the problem at a certain point.

Re: ChargePoint Charging Question

Below is Chargepoint's analysis... Brilliant! It's more or less as we suspected; the car does something unusual but (as far as I can tell) perfectly legitimate, and the EVSE makes an invalid assumption (must be ramping down), and doesn't test that assumption later (is it drawing more current now? O...

Re: Under the Cover--an Inside Look at a 2018 On-Board Charger (OBC2)

i just got kiev back today with the new style On-Board Chargger So naturally, the first thing you did was to rip the covers off :D These will be much easier to repair-- no Waffle Plate™, all the high power diodes and transistors can be seen along the bottom board edges. This is indeed great news. S...

I think a collective thanks is in order for Kiev's presumed part in making this happen! :ugeek:
