摘要： This application provides a charging device and a method for charging an electric vehicle by a charging device. The charging device includes a first charging interface and a second charging interface. The first charging interface includes a first auxiliary power supply contact and a first direct current power supply contact. The second charging interface includes a second auxiliary power supply contact and a second direct current power supply contact. The charging device is configured to detect a first voltage signal of the first auxiliary power supply contact and a second voltage signal of the second auxiliary power supply contact; and enable the first direct current power supply contact and the second direct current power supply contact based on the first voltage signal and the second voltage signal to simultaneously charge the electric vehicle.

摘要： This application discloses a power distribution subrack and power distribution equipment, and relates to the field of circuit technologies. The power distribution subrack includes a subrack body and a collection board, the collection board is disposed inside the subrack body, and the collection board includes a plurality of connection terminals and a plurality of controllers. Second ends of at least two of the plurality of connection terminals are connected to a same controller. First ends of at least some of the plurality of connection terminals are plug-connected to jacks of one or more circuit breakers, and the at least some connection terminals are in a one-to-one correspondence with the one or more circuit breakers. Each of the at least some connection terminals obtains a status signal of a corresponding circuit breaker, and transmits the status signal to a corresponding controller. The controller sends, based on the status signal and by using the corresponding connection terminal, a control signal to the circuit breaker corresponding to the status signal, where the control signal is used to controls connection and disconnection of the circuit breaker corresponding to the status signal. Based on the solution, a quantity of controllers on the collection board is reduced, and material costs of the collection board are reduced.

摘要： A pluggable module is provided, relating to the field of communications device technologies. The pluggable module includes a power control unit (1), an interface unit (2), a monitoring unit (3), and a signal linkage unit (4). The power control unit (1) is connected to the interface unit (2), and the pluggable module can be inserted into an external device by using the interface unit (2). One end of a pull ring (42) is rotatably connected to a bracket (41), and the other end can trigger a signal switch (44). When the pull ring (42) is in an ON state, the signal switch (44) is triggered to send a first switch signal, or when the pull ring (42) is in an OFF state, the signal switch (44) sends a second switch signal. The monitoring unit (3) is configured to control, upon receiving the first switch signal, the power control unit (1) to be powered on, or control, upon receiving the second switch signal, the power control unit (1) to be powered off. In this way, the pluggable module can implement power-on or power-off of the power control unit (1) based on the first switch signal or the second switch signal, thereby implementing hot plugging prevention protection for the pluggable module.
