As shown in fig. 1, an embodiment of the present invention provides an apparatus power supply system, including:
a battery management module 101, a battery 102, an embedded controller EC power management module 103, an EC power switch 104, and an EC 105; wherein the content of the first and second substances,

In the embodiment of the invention, when the external notebook computer body stops transmitting the electric signal, the notebook computer body is not powered by other power supply equipment, so that the battery can be controlled by the battery management module to supply power to the load in the notebook computer body so as to ensure that the load can operate and avoid influencing the use of a user in order to ensure the normal operation of the notebook computer body. If the user plans not to start the notebook computer body for a long time, the shutdown signal for controlling the EC to stop running can be input through the notebook computer body. When the EC detects the shutdown signal and the notebook computer stops transmitting the electric signal, the EC can be disconnected with the EC power supply switch. Because the EC power supply switch is a bridge connecting the EC and the EC power supply management module, the EC power supply switch cannot supply power to the EC at the moment, and the EC stops running. When a user wants to use the notebook computer body, the notebook computer body can be supplied with power through other power supply equipment, so that after the EC is activated, the EC can be connected with the EC power supply switch, and the normal operation of the notebook computer body is ensured. In summary, when the notebook computer needs to stop operating for a long time, the user can cut off the power supply of the EC by stopping the power supply to the notebook computer body and inputting the shutdown signal for controlling the EC to stop operating. Therefore, the loss of the battery and the EC power supply loss can be reduced, and the power signal loss of the EC power management module can be reduced, so that the static energy consumption of the notebook computer is reduced to the maximum extent, and the service life of the battery of the notebook computer is prolonged.

the G pole of the second MOS transistor 202 is connected to the first end of the second resistor 204, the S pole of the second MOS transistor 202 is grounded, and the second end of the second resistor 204 is connected to the control pin of the EC;
a first end of the first resistor 203 is connected to the S-pole of the first MOS transistor 201, and a second end of the first resistor 203 is connected to the D-pole of the second MOS transistor 202.
In the embodiment of the invention, the connection or disconnection between the EC and EC power management modules can be realized by arranging the first MOS tube and the second MOS tube between the EC and EC power management modules. Because the first MOS tube and the second MOS tube have the characteristics of low noise, large dynamic range, low power consumption, easy integration and the like, the EC power supply energy consumption can be reduced, and the use experience of a user can be improved by prolonging the service life of a battery. And a first resistor is arranged between the S pole and the D pole of the first MOS tube, so that the first MOS tube can be prevented from being broken down when the driving circuit does not work and a discharge loop does not exist. And the G pole of the second MOS tube is connected with a second resistor, so that extremely high peak current can be avoided when the high-low jump of the second MOS tube is driven, and the energy of the frequency spectrum component of the second MOS tube is higher, thereby prolonging the service life of the second MOS tube.
It should be noted that a represents the EC power management module, B represents the power supply pin of the EC, and C represents the control pin of the EC.
In order to further improve the service life of the first MOS transistor and the second MOS transistor, as shown in fig. 3, in an embodiment of the invention, the EC power supply switch further includes: a third resistor 301;

And a battery power supply switch is arranged between the battery and the EC power supply management module, and the battery can be disconnected or connected through the battery power supply switch, so that the battery is electrically connected with the EC and the load in the notebook computer body, and the power supply loss is reduced.

1. when only an adapter for supplying power to the notebook computer body exists and no battery exists, the power supply switch of the adapter is in a closed state;
2. when the notebook computer body is powered only by the battery, the adapter power supply switch is in an off state;
3. when the adapter and the battery exist at the same time and the battery electric quantity is lower than the preset electric quantity, the adapter collinear switch is in a closed state.
As shown in fig. 6, an embodiment of the present invention provides a power supply method for an equipment power supply system according to any one of the above embodiments, including:
601: the battery management module, the battery, the EC power management module, the EC power supply switch and the EC are connected in sequence;
603: when the battery management module is used for stopping transmitting the electric signals by the external notebook computer body, controlling the battery to output the electric signals;
605: when detecting a shutdown signal for controlling the EC to stop running from the notebook computer body and the notebook computer body stops transmitting an electric signal, the EC is disconnected with the EC power supply switch;
607: when the EC is used for acquiring an electric signal from the notebook computer, the EC is connected with the EC power supply switch;
609: and when the EC is connected with the EC power supply switch by using the EC power supply management module, the EC is powered by the electric signal from the battery through the EC power supply switch.
In the embodiment of the invention, when the external notebook computer body stops transmitting the electric signal, the notebook computer body is not powered by other power supply equipment, so that the battery can be controlled by the battery management module to supply power to the load in the notebook computer body so as to ensure that the load can operate and avoid influencing the use of a user in order to ensure the normal operation of the notebook computer body. If the user plans not to start the notebook computer body for a long time, the shutdown signal for controlling the EC to stop running can be input through the notebook computer body. When the EC detects the shutdown signal and the notebook computer stops transmitting the electric signal, the EC can be disconnected with the EC power supply switch. Because the EC power supply switch is a bridge connecting the EC and the EC power supply management module, the EC power supply switch cannot supply power to the EC at the moment, and the EC stops running. When a user wants to use the notebook computer body, the notebook computer body can be supplied with power through other power supply equipment, so that after the EC is activated, the EC can be connected with the EC power supply switch, and the normal operation of the notebook computer body is ensured. In summary, when the notebook computer needs to stop operating for a long time, the user can cut off the power supply of the EC by stopping the power supply to the notebook computer body and inputting the shutdown signal for controlling the EC to stop operating. Therefore, the loss of the battery and the EC power supply loss can be reduced, and the power signal loss of the EC power management module can be reduced, so that the static energy consumption of the notebook computer is reduced to the maximum extent, and the service life of the battery of the notebook computer is prolonged.
