Abstract: A charging terminal, a charging connector, a charging pile, and a vehicle. The charging terminal includes a terminal body and a heat dissipation structure. The terminal body includes a housing and a heat conduction structure. The housing includes a first end and a second end. The housing has a sealing cavity. The sealing cavity extends from the first end to the second end. The heat conduction structure is connected to an inner wall of the sealing cavity, and extends from the first end to the second end. The heat dissipation structure is connected to the second end of the housing. According to the solutions of the embodiments, good heat dissipation can be implemented for the charging terminal while ensuring that the charging terminal has good working reliability, so that the charging connector in which the charging terminal is used has a good heat dissipation benefit.

Abstract: An energy storage and charging station. Heat of an energy storage system and heat of a charging system are managed in a centralized manner so that the energy storage system and the charging system can exchange heat by using a heat exchange assembly. A cooling medium in a cooling medium loop separately flows through the charging system and the energy storage system, and the charging system and the energy storage system each exchange heat with the cooling medium loop. Heat generated when the charging system works is transferred, through the cooling medium loop, to the energy storage system for use, to reduce energy consumption required to heat the energy storage system to maintain a temperature, and improve energy use efficiency.

Abstract: The heat exchange module is used in the cabinet that includes a cabinet body. The cabinet body has a first space and a second space. A temperature of the first space is higher than a temperature of the second space. The heat exchange module has a first air circulation system and a second air circulation system, and heat exchange may be performed between the first air circulation system and the second air circulation system. Both an air intake vent and an air exhaust vent of the first air circulation system are configured to be connected to the first space. An air exhaust vent of the second air circulation system is connected to an external space, and an air intake vent of the second air circulation system can be configured to be selectively connected to the external space and/or the second space.
