The invention discloses a power system for transporting a refrigeration unit. A vehicle for transporting cargo, a tractor-trailer system for transporting cargo, and a method of operating a power system of a vehicle for transporting cargo are described. A vehicle (1; 2) comprises: a shaft (5); a transport refrigeration unit TRU (3); and a power system (100). The power system (100) comprises: an energy storage device (115) configured to power the TRU (3) with electricity; a generator (110) configured to generate electric power and supply the electric power to the energy storage device (115); a multi-speed gearbox (105) mechanically coupling the shaft (5) to a generator (110); and a receiver configured to receive a signal indicative of the vehicle (1; 2) and a state of charge of the energy storage device (115), and a controller (120) that controls the multi-speed gearbox (105). The controller (120) is configured to control the vehicle (1; 2) is in the first state to set a transmission ratio of the multi-speed gearbox (105) to a speed-based transmission ratio, wherein the speed-based transmission ratio is based on a first state of the vehicle (1; 2), and wherein the state of charge of the energy storage device (115) in the first state is below a first charge threshold.

    本公开的发明名称是“用于运输制冷单元的动力系统”。描述了一种用于运输货物的车辆、一种用于运输货物的牵引车‑拖车系统以及一种操作用于运输货物的车辆的动力系统的方法。用于运输货物的车辆(1;2)包括:轴(5);运输制冷单元TRU(3);以及动力系统(100)。动力系统(100)包括:被配置成用电给TRU(3)提供动力的能量存储装置(115);被配置成生成电力并且将电力供应到能量存储装置(115)的发电机(110);将轴(5)机械地耦合到发电机(110)的多速变速箱(105);以及被配置成接收指示车辆(1;2)的速度和能量存储装置(115)的荷电状态的数据并且控制多速变速箱(105)的控制器(120)。控制器(120)被配置成当车辆(1;2)处于第一状态中时将多速变速箱(105)的传动比设置为基于速度的传动比,其中基于速度的传动比是基于车辆(1;2)的速度选择的,并且其中能量存储装置(115)的荷电状态在第一状态中低于第一电荷阈值。
