Problems solved by technology

Taking voltage detection as an example, the detection point of the battery voltage is usually the battery connector on the electronic device. The voltage detection circuit needs to be connected to the battery through the battery connector, the flexible circuit board (FPC) of the battery, and the battery protection board. Due to the flexibility of the battery The circuit board (FPC), battery protection board and even the battery have a certain impedance, resulting in an inaccurate voltage detected by the voltage detection circuit on the battery connector
For example, as the charging current increases, the voltage difference caused by the parasitic circuit inside the battery will also increase. If the voltage is collected at the battery connector, the actual voltage of the battery cell will be lower than its rated voltage, making it unable to Full charge will eventually cause the battery to be undurable and reduce user experience

Abstract

The invention relates to electronic equipment, a charging method thereof and a readable storage medium. An electronic device comprises a processor, a battery and a power management module. The power management module comprises a voltage acquisition circuit, the voltage acquisition circuit is connected in parallel to two ends of a battery cell in the battery, and the processor is electrically connected with the power management module, wherein the voltage acquisition circuit is used for acquiring actual voltage at two ends of the battery cell and sending the actual voltage to the processor; the processor is used for acquiring a mode selection signal according to the voltage and sending the mode selection signal to the power management module; and the power management module is used for charging the battery based on a mode corresponding to the mode selection signal in response to the mode selection signal. According to the embodiment of the invention, by detecting the actual voltage at the two ends of the cell in the battery, the voltage error can be reduced, the charging voltage of the battery exceeds the rated voltage, the battery is finally fully charged, and the endurance time is prolonged.

Description

technical field [0001] The present disclosure relates to the technical field of charging, and in particular to an electronic device, a charging method thereof, and a readable storage medium. Background technique [0002] At present, in the process of charging a battery in an electronic device, it is necessary to detect the real-time voltage and current of the battery, and further adjust the charging strategy based on the real-time voltage and / or current. Taking voltage detection as an example, the detection point of the battery voltage is usually the battery connector on the electronic device. The voltage detection circuit needs to be connected to the battery through the battery connector, the flexible circuit board (FPC) of the battery, and the battery protection board. Due to the flexibility of the battery The circuit board (FPC), battery protection board, and even the battery have certain impedances, which cause the voltage detected by the voltage detection circuit on the...
