  • System for braking an electrified vehicle
    Patent number: 12728858
    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.
