Outputs protection when out of range voltage is measured #196
Description
We can add a new type of protection against over-voltage detection on the outputs. For example someone tried to connect 48 V battery while only 40 V is allowed. If that happen TVS diode connected across output terminals will start to conduct but not for too long. That could lead to its damage and then to the rest of the power module.
To avoid such situation, when ADC measured more then max voltage + set margin (e.g. 3 V) firmware can switch off as fast as possible all current mosfets (for current range selection) and turn on parallel and then serial relay. In that case outputs will be effectively disconnected from the load.
If such event is detected, a error message has to be displayed instructing user that forbidden voltage is detected on one of the outputs.
We have to test if such proposal is viable primarily to see a possible consequences of relay switching under the load.
