The portable graphene seedling raising shed has the advantages that the graphene composite support rod is adopted, the support rod is used as a heating device while supporting, the support rod itself is changed into an efficient and uniform heating body, stable and controllable heat supply is provided for the inside of the seedling raising shed, the spraying assembly arranged in the shed is convenient for watering and realizes intelligent control, the portable graphene seedling raising shed can be used for small-scale and family type seedling raising and cultivation in winter, has the characteristics of being light, capable of being quickly folded or stretched, and convenient for users to carry, transport and quickly deploy at different sites.

This invention discloses a control method and system for the working mode of batteries in a battery swapping station. The battery swapping station includes an in-station monitoring platform and several sets of corresponding chargers and charging compartments. Each charger in each set is communicatively connected to the battery pack installed in the charging compartment. The in-station monitoring platform is also communicatively connected to each charger. The control method includes the following steps: the in-station monitoring platform sends a power-on command to the corresponding charger; upon receiving the power-on command, the charger controls the battery pack in the corresponding charging compartment to be powered on at low voltage; the in-station monitoring platform responds to the charging start command by sending a first message to the charger; upon receiving the first message, the charger forwards the first message to the battery pack in the corresponding charging compartment; and upon receiving the first message, the battery pack enters the battery swapping station charging mode. This invention simplifies the structural design of the battery swapping station, reduces costs, and ensures good DC charging of the batteries within the station.
