A vehicle for transporting goods, a tractor-trailer system for transporting goods, and a method of operating a power system of a vehicle for transporting goods are described.The vehicle (1; 2) for transporting goods comprises an axle (5); a transport refrigeration unit, TRU, (3); and a power system (100). The power system (100) comprises an energy storage device (115) configured to electrically power the TRU (3); a generator (110) configured to generate electrical power and to supply the electrical power to the energy storage device (115); a multi-speed gearbox (105) mechanically coupling the axle (5) to the generator (110); and a controller (120) configured to receive data indicative of a speed of the vehicle (1; 2) and a state-of-charge of the energy storage device (115), and to control the multi-speed gearbox (105). The controller (120) is configured to set a gear ratio of the multi-speed gearbox (105) to a speed-based gear ratio when the vehicle (1; 2) is in a first state, wherein the speed-based gear ratio is selected based on the speed of the vehicle (1; 2), and wherein the state-of-charge of the energy storage device (115) is below a first charge threshold in the first state.
