The invention discloses a vehicle-mounted liquid hydrogen cold energy recycling system which comprises a liquid hydrogen container, a cold storage device, a first heat exchange pipeline, a second heat exchange pipeline and the like. The first heat exchange pipeline part is arranged on the side, close to the inner container, of the high-vacuum multi-layer heat insulation layer, one end of the first heat exchange pipeline part communicates with the inner container, and the other end of the first heat exchange pipeline part communicates with the cold storage device and is used for circulating liquid hydrogen output by the inner container; refrigerant is contained in the second heat exchange pipeline, the second heat exchange pipeline is partially arranged on the side, close to the outer container, of the high-vacuum multi-layer heat insulation layer, and the second heat exchange pipeline and the cold storage device are connected to form a circulation loop. Liquid hydrogen cold energy is stored by utilizing the phase change cold storage characteristic of the cold storage material, and then the stored cold energy is recycled through the refrigerant circulation loop, so that the cold energy loss of liquid hydrogen is reduced, the evaporation capacity of liquid hydrogen is reduced, the heat insulation performance of the liquid hydrogen container is improved, and the service life of the liquid hydrogen container is prolonged. The purpose of effectively reducing the heat leakage of the liquid hydrogen container for the heavy truck and the operation power consumption of each vehicle-mounted system is achieved.
