Do you have any ideas to do some simple test on DC charge point ? It is easy for AC charge point, but for DC charge point, commercial tester are very expensive, few models and over complicated if we just want to do rapid test.
When you say you just want to do rapid test, don't you still need to test safety aspects like earth leakage protection? I would have though that these were just as important as checking that there is a DC output and ought not to be skipped. I'm pretty sure the commercial testers verify these.
That one is easy, connect a resistor from one of the lines to ground with a value that gives a current just above the trip threshold.
