Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
My point isn't that a gasket would be a more effective sealing solution for rainwater , it's that it makes disassembly -- even by professionals -- several times more difficult, for no good reason. Some alternatives to RTV: the rotor end cap could have had: a formed elastomeric seal, such as is used ...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
Because the cooling system is unpressurized, the seals don't have a lot of forces working against them, but still . . . elastomers don't remain pliable forever, and best practice is to replace them when they are disturbed. The fact that replacements aren't readily available is likely the only reason...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
I’ve bitten the coolant delete bullet too. Just fitted this from Revolt Systems in California. While machining a part such as this is relatively straightforward for those with the skills to draw it and with CNC, what will impress me is when somebody will start offering the various formed o-rings fo...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
That's not mine, though roughly the right idea. Some of us batted around several sets of dimensions. You'll notice that there's no counterbore dimension on that drawing, and it's 2mm too shallow IMO. And I wouldn't normally specify outside radii such as that; from an engineering standpoint, I prefer...

Re: BMW i3 CCS/charge port controller
That's my diagram
Ricky is successfully charging his RAV4 EV, using the LIM and i3 Charge Inlet that I sold him a while back.
Could you edit the Wiki to add that information (Type 1 LIM does not lock Charge Inlet when AC Charging; Type 2 LIM does)?

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
The second plug, .005" oversize + Loctite 640, passed 30 PSI for two hours with no leakage. 30 PSI pressure differential is at least ten times what that plug should ever see, so I was satisfied with the result.

What do you use for seal material (brownish on the maifold)? That picture is misleading; if you follow the link, it makes more sense. The red gasket you see above is for the pressure test jig I set up to provide proof positive that the plug would not leak. The red gasket is not used for mounting to...

The Tesla (High Power) Wall Connector (that's what Tesla calls their home L2 chargers, as well as "Destination Charger" when installed at eg a hotel) is L2, AC, and does not phone home, just like most all other private charging stations. L2 (AC) charging is a very different animal from DCF...

Re: [WIP]Toyota RAV4 EV (2012-2014): Add CCS DCFC
Still WIP. The LDU has sprung a leak (famous early Tesla Model S problem) and I'm dropping it out for repair next week. Meanwhile, the Lapp disconnects have been dribbling in: one more will ship in April. And like that.

Re: Foccci wakeup/sleep discussions
We can only combine Foccci with a charger that doesn't have its own CP and/or PP handling. We could make the 2k7 pull down and 5V pull-up switchable as well to free up the signals for chargers that do handle CP/PP The above is my use case: adding DCFC to an OEM EV which has none, but its OBC expect...

Re: Develop a QCA7000 board?
I made an interesting observation in my Ioniq: They use a shielded CP line from the engine compartment (where the OBC sits), to the cabin (where the PLC modem sits under the driver seat) to the charge port above the rear left wheel. On my 2014 RAV4 EV, I'm reasonably certain that my CP line is unsh...

Re: Develop a QCA7000 board?
I assumed there will be a momentary-contact switch near the charge inlet, to do user-input things such as: * discontinue charging * turn on the charge port light (to aid in guiding the nozzle to the port) * or whatever . . . That user-input button is, in my mind, one of several wake-up triggers for ...

Re: Develop a QCA7000 board?
I took another look at the LIM. According to the circuit diagram, PP is connected to pin 2 (A250-B2) in the CCS2 version. No resistor is shown in the charging plug. CCS1 has an additional jumper from pin 2 to pin 6. This pin 6 is connected to GND (PE) in the LIM via 2k7. This means: In EU no 2k7 to...
