Embodiment 2

[0051] In order to facilitate the detection of the voltage at both ends of the battery and the current flowing through the circuit of the protection circuit, the protection circuit 213 includes a power metering circuit, and the power metering circuit is used to detect the voltage value at both ends of the battery and the current flowing through the protection circuit 213 where it is located. For the current value, the main control unit 201 obtains the voltage value and the current value detected by the electricity metering circuit by communicating with the electricity metering circuit.

[0052] Specifically, each of the charging and discharging interfaces further includes a communication interface of the electricity metering circuit. Through the electrical interface of each charging point, the main control unit can obtain the voltage value and current value detected by the power metering circuit.

[0053] The power metering circuit located in each protection circuit is used to...

Embodiment 3

[0055] In order to improve the charging efficiency, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, the main control unit 201 is also used to send the second voltage control signal to the adapter 204, and control the adapter 204 to increase the value according to the set first voltage. The output voltage is increased based on the first fixed voltage to increase the first current value of the powered-on fast charge charging circuit 202 .

[0056] Specifically, when charging the battery, the battery can be charged with a first fixed voltage, because the first fixed voltage is greater than the working voltage of the battery, so it can ensure that the battery power can be continuously increased.

[0057] In order to further improve the charging efficiency, in the embodiment of the present invention, by increasing the output voltage of the adapter 204 connected to the fast charging circuit 202, the current flowing through each powered fas...

Embodiment 4

[0068] When the power of the battery is saturated, the output voltage at its two ends is constant. If the battery is charged at this time, it will cause damage to the battery. In an embodiment, the main control unit 201 is further configured to obtain a first voltage value at both ends of the battery 203; if the first voltage value reaches a preset first voltage threshold, send a fifth voltage control signal to the adapter 204, The control adapter 204 reduces the output voltage according to a set second voltage increase, wherein the second voltage increase is smaller than the first voltage increase.

[0069] Specifically, the first voltage threshold may be no greater than the output voltage when the battery is saturated. If the first voltage output from both ends of the battery reaches the preset first voltage threshold, it means that the current battery 203 is close to being saturated. At this time, the adapter 204 is controlled to reduce the output voltage to the fast chargi...

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to an electronic device and a charging control method based on the electronic device. Background technique [0002] With the advancement of science and technology, electronic devices are more and more widely used in people's work and life. While providing fast and convenient services for people's work and life, people are increasingly dependent on electronic devices. Gao, work and life are already inseparable from electronic devices. Because the normal operation of electronic equipment requires the battery in the electronic equipment to provide power, but with the accelerated pace of people's work and life, there is not much time to wait for the long charging process of the battery in the electronic equipment, how to improve the charging efficiency has become a Problems to be solved. [0003] In the prior art, the realization of improving the charging efficiency is mainly b...
