[0050] As a preferred embodiment of the present application, continue to refer to Figure 1 and Figure 6 As shown, the commercial vehicle sleeper also includes an energy storage device 6 and a control component 7, the energy storage device 6 is connected to the photovoltaic device 3 and the heating component 4, the ventilation component 5, respectively, and the energy storage device 6 is used to store the electric energy generated by the photovoltaic device 3 and to supply energy to the heating component 4 and the ventilation component 5. Preferably, the energy storage device 6 uses a storage battery. The control component 7 includes a heating switch 71, a ventilation switch 72 and a controller 73, and the controller 73 is connected to the heating switch 71, the ventilation switch 72, the photovoltaic device 3, the energy storage device 6, the heating component 4 and the ventilation component 5 respectively.
