Automatic charging voltage and current adjustment through the wireless message transmission of a smart charger

This design provides an automatic charging voltage and current adjustment through the wireless message transmission of a smart charger. The smart battery charging voltage and current can be adjusted according to different ambient temperatures to provide a safe operation. In addition, the current battery status and warning message can be transmitted through wireless message transmission to a smartphone. The user can use the application on the open platform of the smartphone which receives the smart battery's real-time status. If the smart battery has an abnormal status, the abnormal status notification will be sent to the smartphone. Because the different batteries may have different battery characteristics, the charging procedure needs to be in keeping with the battery characteristics in order to set the appropriate parameters. This design also provides for the user to set the charging parameter values.
