Abstract: A state-monitoring-based fall-into-water protection method and a related device are provided, are applied to an intelligent storage battery box. The method includes the following. An acceleration of the intelligent storage battery box and a humidity of an environment in which the intelligent storage battery box is located are detected first. A space occupation state of the intelligent storage battery box is determined according to the acceleration and the humidity. The space occupation state includes a non-fall-into-water state and a fall-into-water state. If the space occupancy state of the intelligent storage battery box is the fall-into-water state, a fall-into-water protection start instruction is generated, and a fall-into-water floatable apparatus is controlled to inflate a floatable airbag in a folded state according to the fall-into-water protection start instruction.

Abstract: A method for charging control includes the following. A reference charging frequency at which a target vehicle has been charged through the battery pack is acquired in the case where a charging event corresponding to the target vehicle is detected. The target vehicle is charged in a fast-charging mode through the mains-borne control system in the case where the reference charging frequency is determined to be less than or equal to a first preset frequency and a charging port accessed by the target vehicle is detected to be a fast-charging port. A target charging mode is acquired and the target vehicle is charged in the target charging mode in the case where the reference charging frequency of the target vehicle is determined to be greater than the first preset frequency and less than or equal to a second preset frequency.

Abstract: A portable power management method and server are provided. The method includes the following. A server receives a delivery request sent by a user terminal, where the delivery request is sent in response to a confirmation instruction. The server determines a first battery exchange station within a preset distance range from a location of the user terminal in response to the delivery request. The server determines a second portable power that matches the delivery request from portable powers included in the first battery exchange station. The server generates a delivery task for the second portable power based on the location of the user terminal and indication information of the second portable power. The server sends the delivery task for the second portable power to a delivery terminal, where the delivery task indicates that the second portable power is to be delivered to the location of the user terminal.

Abstract: The present invention discloses a multifunctional bone conduction earphone, including a left earphone body, a right earphone body and speaker position adjustment mechanisms. The left earphone body includes a left ear hanger body; the right earphone body includes a right ear hanger body; and the speaker position adjustment mechanisms are arranged on the ear hanging bodies and used for adjusting positions of speaker bodies. In a relatively noisy environment, the speaker position adjustment mechanisms are adjusted, so that the speaker bodies cover ears, thereby playing a role of shielding external sounds and avoiding interference from the external sounds.

Abstract: A cell and a battery are disclosed. The cell includes: a barrel, a first end cover and a second end cover being arranged at two ends of the barrel respectively, the barrel, the first end cover and the second end cover defining an accommodating space in which a battery cell assembly is arranged; and a heat exchange pipe passing through the first end cover, the second end cover, and the accommodating space, and an outer wall of the heat exchange pipe being in contact with the battery cell assembly. The battery includes at least two cells, the heat exchange pipes of the adjacent cells communicate with each other, so that external fluid can enter the heat exchange pipe at one end of the battery pack and then exchange heat with all the cells.

Abstract: A protective enclosure, an energy-storage apparatus, and an electricity-consumption device are provided. The protective enclosure includes a main housing and a heat-conducting member. The main housing defines a heat-conducting hole. The heat-conducting hole extends through the main housing in a thickness direction of the main housing. The heat-conducting member is mounted at an inner side of the main housing, is integrated with the main housing, and covers the heat-conducting hole.

Abstract: A method for adjusting a state of an energy-storage battery, a terminal, and a non-transient computer-readable storage medium are provided. The method is applied to an electronic apparatus. The electronic apparatus includes a battery-state-adjustment button. The method includes the following. Touch information input by a user through the battery-state-adjustment button is received; state-adjustment information of the energy-storage battery is determined according to the touch information; state adjustment is performed on the energy-storage battery according to the state-adjustment information to obtain a target state adjusted; and the target state is displayed by a display module in the electronic apparatus.
