Hey thx for having me.
I have already read much about my new old car, which I love. Bought a 2012 EU model with only 26.000km on it.
Have added a diesel burner/heater (Webasto) and are planing to added cruise control and buttons.
I have fixed my AC compressor, which had no rubber dampers left and was "flying" around "below deck".
Enough about what I have been doing to the car.
The 12V battery have been ill treated at the dealership where I bought it. So I have already managed to run it down on me once with a lot of use of the diesel heater (power hungry) on a long trip.
It needs to be replaced. Think I will go with something with more Ah (or Wh). Maybe LiFePO4's or 18650's because I have some in storage.
Power rating on DC/DC converter for 12V
Does anyone know how much power it does supply while charging the battery and running the car?
I am asking, because my radio died on me today (which I saw as a sign of low battery earlier) and I had phone in the AUX for USB charging at max 750mA, while the AC was running on a rather low speed, the radio was on, and full lights (no high beam) were on. All which I think should not run down the 12V battery.
When the radio died (with a large noise and I tried it twice), I then turned the radio, lights and AC off. Had running lights/fog lights on in front.
I charged only 1200mA to the 12V battery when I return home after testing that the car actually produced 14.4V when turned on (READY). Odd I think.
The weather is rather hot (26 degrees C) if that can have anything to do with it.
Would it make any sense to take the OBC apart and refurbish the two snupper caps before they die on me? And is there anything else I could do while inside the OBC?
I am electrical engineer making EVs for airports on a daily basis and good at soldering stuff.
Anything to add? New vacuum pump? Car has never been serviced at the dealer.
Thank you in advance
