Abstract

The embodiment of the invention provides a charging circuit, method and device and electronic equipment. The charging circuit comprises: a first temperature sensor, a second temperature sensor, a controller, a first charging path and a second charging path; each charging path is provided with a resistance regulator and a charging chip which are connected in series, the resistance regulator is connected with the output end of a power adapter, the charging chip is connected with the input end of the battery, the controller is connected with the resistance regulator, and the first temperature sensor and the second temperature sensor are connected with the input end of the controller; in the charging process, the output voltage of the power adapter and the charging voltage of the battery are kept unchanged, and when it is detected that the temperature of any charging chip is higher than a first preset temperature, the controller controls the resistance regulator on the corresponding charging path to improve the path impedance on the charging path, thus, the temperature of the charging chip is reduced to be lower than the first preset temperature, and the problem of tradeoff between charging temperature rise and charging speed in an existing charging scheme is effectively solved.

Description

technical field [0001] This document relates to the technical field of charging, in particular to a charging circuit, method, device and electronic equipment. Background technique [0002] With the development of the mobile era, people spend more and more time on mobile terminals, and with new technologies such as the fifth generation mobile communication technology (5th Generation Mobile Networks, 5G) and artificial intelligence (Artificial Intelligence, AI) Technology has been added to mobile terminals. These situations have put forward higher and higher requirements for the battery life of mobile terminals such as mobile phones. Charging power, so as to increase the charging speed, to improve the user's charging experience. [0003] However, in the process of constantly pursuing the charging speed, it often appears that the faster the charging speed, the higher the temperature rise of the mobile phone or charger end, and this directly affects the user experience, because...
