-I have been told that when driving an electric car, reading of the current (which is nearly proportional to electric power) is more useful than a reading of the motor's rotational speed. The rev meter (the term "tachometer" might be misleading in German) was "dead" anyhow after the conversion, so I made an adapter circuit that makes it now display the current on the traction circuit.

 The battery computer does measure the current with its hall sensor and displays it as a digital number, but unfortunately it has no output for this measure. So, my adapter also has to sense the current in parallel.
