Abstract

The invention discloses an intelligent charging detection circuit and a movable power supply. The intelligent charging detection circuit comprises a power supply circuit, a controller, a charging interface and an insertion detection circuit; the insertion detection circuit is used for detecting the variation of electrical parameters of the charging interface, a switch element is controlled by the variation of the electrical parameters of the charging interface to be on and off, a corresponding command signal is generated by utilizing the variation of the on-off state of the switch element and is transmitted to a controller, and the command signal is used for recognizing the insertion state of a charging device. A charging device insertion detection circuit is additionally arranged in a movable power supply, so that the movable power supply is enabled to stay at a dormant state during the non-charging period, the current loss of the movable power supply can be reduced, and the use time of the movable power supply is prolonged. A current monitoring circuit is additionally arranged in the movable power supply, the size of the charging size can be monitored in real time, and the battery application efficiency of the movable power supply can be improved by reducing the constant-voltage charging time while the safety of the movable power supply and the charging device is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of charging equipment, and in particular relates to a structural design of a charging detection circuit and a mobile power supply product designed using the charging detection circuit. Background technique

[0002] With the increasing variety of digital products and the increasingly diversified functions, people use digital products more and more frequently. Because the current digital products are generally small in size, the space reserved for batteries inside is very limited, and it is impossible to use larger batteries to power digital products. Limited by the volume of the battery, the capacity of the battery will not be too large, which will greatly limit the standby time of digital products, and it needs to be charged frequently. Therefore, how to increase the standby time of digital products and how to maximize the functions of digital products is of great importance.
