Vectux ICL initial version - not quite good enough....
Submitted by Mik on Sat, 04/04/2009 - 21:23
This is a diagram of the ICL which I used for reconnecting the battery in the Vectux after the two motor controller repairs, for the fuse replacement following them, and for the reconnecton of the batteries after the battery rework and M-BMS installation:
The gap between the disconnected ends of the Andersons 125A connector are bridged with one simple cable and with another cable with a 2460Ω resistor and a digital ammeter in series.
The design was inspired by observing the Australian Vectrix Authorized Person (VAP) using an ICL that was connected like this:
This "Aussi ICL" had an Andersons connector on each end....
Both these designs are severely flawed, because the ICL needs to be removed before the Andersons connector can be closed!
That causes some inrush current, because the inrush current increases again immediately after disconnection of the ICL.
Depending on the time taken to connect the Andersons connector it will have the same effect as if no ICL was used in the first place.
It probably only takes seconds for the inrush current to reach almost full intensity again!
