摘要： A power supply system (10) is used for supplying power to a power system of an electric tractor and comprises a bracket (100) that is provided above and below a frame of a transport trailer, first cases (200) that are provided on the bracket and first power battery packs that are suspended inside the first case. Each of the first cases is provided with a first ventilation structure and a second ventilation structure (211) so that while the transport trailer is moving, wind can enter the first case from the first ventilation structure and be discharged from the second ventilation structure, thus achieving further cooling and heat dissipation for the first power battery packs and avoiding service life being impacted due to the first power battery pack overheating.
