- Proximity Pilot for the moment because we know that the wire inside the EVSE connected to the Proximity Pilot pin doesn't go anywhere. It's been cut off so we can ignore all the stuff on the PP pin. But the Control Pilot, this pin 4, goes into a diode and down through a 2.74 K resistor to ground which is protective earth. So if we put a diode and a resistor 2.7 K, I haven't got a 2.74, across those two connections then will the EVSE see this as a car? There is also the option here to switch in a 1.3 K resistor via this relay but we'll come back to that later. Right diode and 2.7 K resistor and I'm going to be really lazy here and just twist these together which I know is really naff but I just can't be bothered to get the soldering iron out so let's twist those together and then I'll connect these to my terminal block and we'll see what happens. Let's actually do this sort of live as it were. Put my finger on there.
因為我們知道，EVSE 內部連接到接近先導引腳的電線並不通向任何地方。它已被切斷，是以我們可以忽略 PP 引腳上的所有內容。但控制引腳，即 4 號引腳，連接到一個二極管，然後通過一個 2.74 K 電阻器接地，即保護接地。是以，如果我們在這兩個連接點上加一個二極管和一個 2.7 K 電阻（我沒有 2.74 K 電阻），那麼電動車控制器會把它看作一輛汽車嗎？我們還可以通過繼電器接通一個 1.3 K 的電阻器，不過我們稍後再討論這個問題。右邊是二極管和 2.7K 電阻器，我想偷個懶，直接把它們擰在一起，我知道
- No, not yet. Now I was just wondering whether this device would time out. I've got my diode and resistor on there permanently. Will this time out if it doesn't see whatever it needs to see to go into charging mode? But it doesn't seem to be timing out. It seems quite happy to wait there and I think the next stage of this is to close this relay as it were and put this, is it 1.3 or 1.2? I think it's 1.3 K there. I'm not sure if I've got a 1.3 K resistor and put that also across, yes it's switched to ground isn't it? So also across this resistor thus pulling this voltage down even further. You see this voltage 12 volt is sourced here, 12 volts. It goes to a 1 K resistor. So by pulling it down through this diode with a 2.74 K resistor, we pull the 12 volts at this point down to about 9 volts and that indicates that the car is connected. So it says connecting. Then the car should respond by closing this switch with an additional resistance further pulling this voltage down from 9 volts to 6 volts and that's probably what will trigger the EVSE to switch on the mains and then this bulb should come on. Well I don't have a 1.3 K but I do have a 1.2 K so let's put that across this resistor and see what happens. And yes it's gone into charging. Now my lamp hasn't come on. That's probably because of that switch.
不，還沒有。我只是想知道這個裝置會不會超時。我已經把二極管和電阻器固定在上面了。如果它看不到進入充電模式所需的任何信號，會不會超時？但它似乎沒有超時。它似乎很樂意在那裡等待，我想下一階段應該是關閉繼電器，然後把這個，是 1.3 還是 1.2？我想應該是 1.3 K。我不確定我是否有一個 1.3 K 的電阻，把它也跨接起來，是的，它是接地的，不是嗎？所以也要跨接這個電阻，從而進一步拉低電壓。你看，12 伏電壓就來自這裡，12 伏。它連接到一個 1 K 電阻器。通過這個二極管和一個 2.74 K 電阻器，我們
