Abstract: A crimping power module includes a shell (10), a cover (12), and an electric insulation substrate (13) crimped to a heat dissipation device. The cover and the substrate are respectively mounted to a first surface (111) and a second surface (112) of the shell. The second surface defines an annular slot (113) in a position facing sides of the substrate. The slot is embedded with a first elastic member (15) elastically abutted against the substrate. The elastic member is higher than the second surface, allowing the shell to adjust a pressure flexibly applied on the heat dissipation device by the substrate. An elastic buffer is provided through defining the slot embedded with the elastic member, to prevent the substrate from fracturing, and adjust the pressure to ensure tight crimping between the substrate and the heat dissipation device, which decreases thermal resistance, and increases heat dissipation efficiency.

Abstract: A battery management system for an electric automobile and a control method are provided. The battery management system includes a temperature monitoring device (10) connected to a battery compartment of the electric automobile for monitoring the battery temperature and transmitting the battery temperature to a main control device (12), a refrigeration circulation channel (11) connected to the battery compartment for circulating a refrigerant so as to refrigerate the batteries. The main control device is connected to an acquisition device and the refrigeration circulation channel, for controlling the refrigerant to be circulated so as to refrigerate the batteries when the battery temperature exceeds a preset upper limit value. With the battery management and the control method, the impact of the high temperature on the service life and the capacity and the like of the batteries can be reduced, and the service life of the batteries can be prolonged.

Abstract: Seed coat color is a very important trait in oilseed type Brassica crops. Identification of the genes controlling the seed coat color is essential to the manipulation of these genes to develop new yellow-seeded germ plasm for oilseed breeding. The Brassica TTG1 and TT1 genes may be used to control seed color in plants.
