Abstract: An embodiment of the present application provides a battery charging method, an electronic device, and an electric device. The charging method provided by the present application performs alternate charge and discharge cycles with high and low currents during the fast-charging-cycle process, which can eliminate polarization caused by high-current fast charging with only a slight increase in charging duration, improve interface lithium plating, prevent abnormal battery cell voltage plunging phenomena, and balance regional SOC differences at the interface caused by fast charging. Furthermore, low-current charging can reduce temperature rise differences within the battery cell, reduce regional overcharging and over-discharging phenomena, improve lithium plating, and also enhance the usable life of the battery, solving the problem that the existing charging method cannot improve lithium plating on the negative electrode of lithium batteries while ensuring fast charging performance.

Abstract: Techniques are disclosed relating to improving the efficiency of geolocation queries via geospatial cells and query parameter caching. In various embodiments, a system receives a request from a user device to access geolocation information of entities and determine a first geographic location of the device. The system identifies that the first location is within a geospatial cell stored in a database cache and determines whether query parameters corresponding to the cell are stored in the cache. The system may retrieve the cached query parameters corresponding to the geospatial cell and execute a geolocation query on a database storing location information for different entities based on the cached query parameters. Results of the geolocation query may be different from query results of one or more other queries executed, based on the cached query parameters, for other user computing devices located within the given geospatial cell based on the cached query parameters.

Abstract: Techniques are disclosed for implementing cross-zone communication for computing zones executing different coding protocols. A server computer system may receive, via a proxy layer of a first instance of an application executing within a first computing zone according to a first set of coding protocols, a request for a service executed via a second instance of the application in a second computing zone according to a second, different set of coding protocols. The system may alter, via a remote layer of the first instance, a set of data specified in the request to comply with the second, set of protocols. The system may transmit, via the remote layer of the first instance to a remote layer of the second instance, the altered set of data. The system may advantageously provide a simplified development interface allowing for both development and testing within a local environment without deployment of multiple different services.

Abstract: Methods and systems are presented for assisting a user to identify and evaluate features for use in a machine learning model configured to perform a task. Based on graph data associated with a graph data structure, a user interface is provided on a device.

Based on the attribute values, a value corresponding to the feature candidate can be calculated. The value can be used to evaluate the effectiveness of the feature candidate in performing the task. The feature candidate can then be incorporated into the machine learning model as one of the input features.
