Abstract

The invention discloses electronic equipment, and the electronic equipment comprises a first battery; a second battery; a power circuit which can receive the input of an external power supply, can use the input to supply power to electronic equipment, and can charging the first and second batteries; a charging and discharging control circuit which is connected with the power circuit, the first and second batteries, and a charging and discharging switching circuit, is used for detecting the parameters of the first and second batteries, is used for receiving a signal from the power circuit so as to judge whether there is an external power supply connected with the electronic equipment or not, and is used for generating a corresponding switching operation signal based on the judgment results and detected parameters and transmitting the switching operation signal to the charging and discharging switching circuit; and the charging and discharging switching circuit which is connected between the output end of the power circuit and the first and second batteries, and is used for switching the charging and discharging states of the first and second batteries according to the switching operation signal.

Description

Technical field [0001] The invention relates to an electronic device and a dual-battery charging and discharging switching method, in particular to an electronic device capable of effectively reducing the risk of loading failure of a dual-battery charging and discharging strategy caused by software, and a dual-battery charging and discharging switching method applied to the electronic device method. Background technique [0002] Currently, in electronic devices with two batteries, software (such as system software or App that controls the battery charging and discharging strategy) is usually used to control the charging and discharging of the battery. For example, first read the power of the two batteries through the software. Voltage and other parameter information, and then the software controls the charging and discharging strategy for the two batteries according to the read parameter information. However, this way of using software to control the charging and discharging str...
