    摘要: This application provides a charging protection method, a terminal, and a charger. The terminal obtains a parameter from the charger, including at least one of an input voltage value and an output current value of the charger and a temperature value of a charging output port of the charger. When a parameter value is greater than a threshold, the terminal terminates a charging process based on a relationship between a corresponding threshold and at least one of a difference between the output current value of the charger and an input current value of the terminal, a power loss from the charger to the terminal, and a temperature value (including the temperature value of the charging output port of the charger and a temperature value of a charging input port of the terminal). A charging port can be prevented from being overheated, and a probability that an overheated charging port causes an accident can be effectively decreased.

    摘要: A current differential protection system for a multi-terminal power line includes a current sensor for sensing a current at a local terminal, a controller (80) for time synchronizing the local terminal and remote terminals, and a fault detection module (98) to detect a fault in the multi-terminal power line if a differential current exceeds a threshold value. The controller (80) includes a time measurement exchange module (94) for exchanging time stamp data with remote terminals, an upper range clock for exchanging time stamp data with remote terminals and a lower range clock for indexing the current at the local terminal. A first time period of the upper range clock is N times a second time period of the lower range clock where N is a number of multi-terminals. The controller (80) includes a clock offset calculation module for determining an average time offset based on time stamp data from remote terminals and the local terminal.
