This application relates to a charging protection circuit. The charging protection circuit implements overcurrent protection by using a four-terminal NMOS switching transistor. In the solution provided in this application, floating management is performed on a Sub port of the four-terminal NMOS switching transistor. Specifically, when the four-terminal NMOS switching transistor is turned on, potential of the Sub port is pulled up, to avoid an excessively large internal resistance of the four-terminal NMOS switching transistor caused by an excessively large voltage between the Sub port and a drain of the four-terminal NMOS switching transistor. In addition, this application further provides a charging circuit and an electronic device.

Charging station for electric vehicles

A backlight driving method and a display panel are provided. The backlight driving method provided by the present application uses pulse width modulation technology to modulate a low-level pulse width of a scan signal. By increasing a low-level pulse width to increase the pulse period, a number of high-level pulses is reduced, thereby reducing a high-level pulse time. Therefore, a time for a TFT to receive a high-level voltage is also reduced, thereby improving a stability of the TFT and also improving a problem of a threshold voltage drift of the TFT.

An image deployment method includes obtaining a configuration policy for a container, where the configuration policy for the container includes an autoscaling policy or a replication control policy. The autoscaling policy includes a first image identifier, a maximum quantity of containers corresponding to the first image identifier that can be deployed, and a quantity of currently deployed containers corresponding to the first image identifier. The replication control policy includes a second image identifier and a quantity of containers corresponding to the second image identifier that are expected to be deployed. The method determines an identifier of a to-be-deployed image according to the configuration policy for the container.

Image deployment method and apparatus

This application discloses an image deployment method, where the image deployment method is applied to a container system. Information about an image that has been deployed on each host is collected. After an image tag of a to-be-deployed image is obtained, a degree of overlapping between the image that has been deployed on each host and the to-be-deployed image is determined. A host with a higher overlapping degree needs to download a smaller amount of data when deploying the to-be-deployed image and deploys the to-be-deployed image at a higher speed. Finally, a management node selects, according to overlapping degrees of the hosts, a deployment host for deploying the to-be-deployed image.
