Re: Tesla's NACS and the Future of Fast Charging in North America
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...

I don't have a LIM anymore, but . . . is it possible to disable the LIM's termination? Desolder a resistor on the PCB?

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...

Ah, understanding.

This wasn't clear to me upon ...

Re: Develop a QCA7000 board?
Does clara have a defined interface to receive BMS communications regarding maximum charge current & voltage, dynamically?
In my use case, it may take some time for the battery heater to sufficiently heat the modules to a temperature when they can begin to accept higher charge current.

Re: BMW i3 CCS/charge port controller
Please expand on this.
The BMS communicates limits . . . via CAN? To the ZV -> LIM (via CAN) -> DCFC EVSE (via PLC)?
If the BMS is communicating limits to the ZV, does the ZV have preset or user-defined communication profiles for various BMSs?

I'm looking for a Tesla LDU coolant manifold, so if someone is breaking one for a rotor for Affe, perhaps you also have a coolant manifold. It's the part that carries the problematic coolant seal, on the motor/rotor end of the LDU.
