I think voltage should be practically always identical at the DC
converter output to the 12V battery, as there normally isn't
anything between, and it should also be identical to the 12V reading
of the module, as it's powered directly by the 12V circuit.<br>
<br>
12V current will probably normally only be available as the DC
converter output, which partially charges the 12V battery, but
probably mostly powers the 12V components. So yes, that's probably
misplaced unter "v.b." – my bad.<br>
<br>
Does any of your cars provide a 12V current reading at the battery?
Or a temperature of that battery? These could help diagnose 12V
battery issues early. But the voltage is normally sufficient to
estimate degradation.<br>
<br>
That's how my Twizy 12V battery looked like when it finally died…
luckily not by rapid unscheduled disassembly, but it sure smelled
like due…<br>

can see the current the converter is putting out. but so far I
didn’t find current figure for the actual 12v battery.<br>

For the e-Up we can also get voltage & current of the dcdc
<br>
converter :)

the dcdc converter I suggest

including the following as well as temp:
<br>
<br>
v.c.12v.voltage 14.2V
<br>
v.c.12v.current 10A
<br>
v.c.12v.power 0.14kW
<br>
<br>
For the Leaf I have found the dcdc output voltage, still looking
for a
<br>
current reading to calculate the power output.
