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.

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 system for braking a vehicle is provided. The system comprises a powertrain comprising an electric machine arranged to propel the vehicle and a transmission arranged to transfer power between the electric machine and the driving wheels of the vehicle. The system further comprises a resistor device arranged to dissipate electric energy generated by the electric machine during braking of the vehicle, and an airflow generating device arranged to generate an airflow over the resistor device. The airflow generating device is arranged to be mechanically driven by the powertrain so as to generate said airflow. By (mechanically) driving the airflow generating device by means of the powertrain, the airflow generating device does not need its own motor, thereby making the system less complex. Further, the driving of the airflow generating device by means of the powertrain will consume energy itself, contributing to braking the vehicle.
