Abstract: An electronic circuit breaker comprising: an input connected to an electric DC power supply; an output connected to a load; the input connected to the output via a switch, said switch is controlled via a switch control line between an “ON”-state and an “OFF”-state; a switch driver connected to the switch control line, said switch driver configured to control the switch; and a switch protection, a voltage detection branch configured to output a first electric potential indicative of the electrical potential difference between the input and the output; a comparator circuit configured to compare the first electrical potential with a first threshold voltage, said first threshold voltage is indicative of an over-current level flowing through the switch; and a gate controller connected to the switch disable line and configured to disable the switch by connecting the switch control line to a potential which causes the switch to enter the “OFF”-state.

Abstract: A battery junction box, comprising: a first input connected to a first output via a switch circuit, which switch circuit is configured to connect the first input to the first output upon receiving a control signal from a controller; the battery junction box further comprises a second input connected to a second output, via a fuse and a main switch arranged in series. The switch circuit further comprises at least a first branch with a semiconductor switch between the first input and the first output, which semiconductor switch has a control line connected to the controller; and the switch circuit further comprises a second branch with a snubber circuit, which second branch is parallel with the first branch between the first input and the first output; and a flywheel diode with a first terminal connected to the first output, and a second terminal connected to the second output.
