Abstract: In a method of charging a battery, a charging control device obtains a battery parameter that includes an electrode parameter of the battery and one or more of a structure parameter, a manufacturing process parameter, an electrical parameter, an electrolyte parameter, a diaphragm parameter, and a thermophysical parameter of the battery. The charging control device inputs the battery parameter input into a battery model represented by an ordinary differential equation to obtain a safe charging boundary value of the battery in n cycles, where n is greater than or equal to 2 and less than or equal to N, N is a cycle life of the battery, and the n cycles refer to n cycles selected from 0 to N cycles. The safe charging boundary value is a maximum charging current in which no lithium plating occurs on the battery in different states of charge SOCs and at different temperatures.

Abstract: A packet forwarding method, a device, and a system, where a first provider edge (PE) device separately sends request packets to a second PE device and a third PE device. The second PE device receives the two request packets separately using a primary pseudo wire (PW) and using a secondary PW, the third PE device, and a bypass PW, switches preferential forwarding statuses relative to the primary PW and the bypass PW to a balance state, and then, notifies the first PE device and the third PE device using a response packet. The first PE device switches preferential forwarding statuses relative to the primary PW and the secondary PW to the balance state based on the response packet. The third PE device switches a preferential forwarding status relative to the bypass PW to the balance state based on the response packet.

Abstract: An information sharing method and related terminal device are provided. In the method, a first terminal device first establishes a communication connection to a second terminal device. When the first terminal device approaches a third terminal device, the first terminal device performs identity authentication on the third terminal device through near field communication (NFC). After determining that the identity of the third terminal device is valid, the first terminal device sends communication link information to the third terminal device by using a short-range wireless communication technology. After receiving the communication link information, the third terminal device establishes a communication connection to the second terminal device by using the communication link information when detecting the second terminal device. In the foregoing solution, communication connections can be quickly and conveniently established, and information sharing can be implemented among a group of terminal devices.

Abstract: A link fault detection method includes sending, by a first network device, data traffic to a second network device by using a plurality of first label switched paths (LSPs). The method also includes determining, by using each of the plurality of first LSPs within a preset period, whether a first link detection packet from the second network device is received. The method further includes determining an LSP of the plurality of first LSPs for which the first link detection packet is not received as a first faulty LSP. The method additionally includes calculating a first unavailability of the plurality of first LSPs based on the first faulty LSP. The method also includes triggering the plurality of first LSPs to stop transmitting the data traffic according to the first unavailability of the plurality of first LSPs.
