Abstract: The present disclosure provides a battery pack, comprising: battery cells; a coolant tank for storing a coolant; a cooling circuit in communication with the coolant tank; a driving device for driving the coolant to flow; and a fire extinguishing pipeline connected to the cooling circuit; wherein, the fire extinguishing pipeline includes: a spraying pipe extending above the battery cells and forming an opening after being heated.

Abstract: A method and apparatus for monitoring a vehicle, a cloud control platform, and a system for vehicle-road collaboration are provided. The method includes: acquiring real-time driving data of each vehicle in a preset vehicle set; matching, in response to receiving event information of an event occurring on a driving road of a vehicle in the preset vehicle set, the event information with the real-time driving data of each vehicle in the preset vehicle set to determine a target vehicle involved in the event; and acquiring video information of the target vehicle during occurrence of the event based on the event information.

Abstract: A high-temperature protection method for a solid state drive (SSD) and an implementation device thereof are provided. The device includes a temperature measurement circuit, a host communication interface, a SSD main controller and NAND Flash storage medium chips, wherein the SSD main controller is for controlling data transmission and command interaction between a host and the NAND Flash storage medium chips, including a SATA/PCIe (serial advanced technology attachment/peripheral component interconnect express) physical controller, a high-temperature control manager, a main controller core, a RAM (random access memory) and a NAND Flash controller.

Abstract: A method of preparing a mechanoluminescent material includes the steps of: a) providing a mixture including precursors of a base material, a fluxing agent, and at least one lanthanide ion; b) heat-treating the mixture to obtain the mechanoluminescent material; and c) optionally grinding the mechanoluminescent material into powder form; wherein the fluxing agent facilitates incorporation of the at least one lanthanide ion into the base material. A composite material includes a first mechanoluminescent material, wherein the first mechanoluminescent material includes at least 2-3 mol % of a lanthanide ion.
