The invention discloses a charging and discharging control method and device, a battery and electronic equipment. The method comprises the following steps: receiving system state information of the electronic equipment; and under the condition that the system state information shows that the system state of the electronic equipment is switched from a working state to a system closing state, switching a charging and discharging mode of a battery of the electronic equipment from a first mode to a second mode through on-off control of the module switch, wherein the charging voltage of the first mode is greater than the charging voltage of the second mode, and the discharging voltage of the first mode is greater than the discharging voltage of the second mode. According to the invention, on-off control can be carried out on the module switch according to different working states of the system, the system efficiency in a closed state of the system is improved, the power consumption is reduced, and standard requirements are met.
Description
technical field [0001] The present invention relates to the field of power electronics technology, in particular to a charging and discharging control method, device, battery and electronic equipment Background technique [0002] Electronic devices use power adapters for charging and discharging and normal power supply technologies have been widely used, for example: notebook computer power adapters. However, the system has the problem of high power consumption in the DC S5 state (all devices including the power supply are turned off), which cannot meet the corresponding standard requirements. At present, the methods of shutting down the power consumption device or making EC (Embedded Controller, embedded controller) enter a deep sleep (deep sleep) state are mainly adopted. However, there is still the problem of not meeting the standard requirements after the power consumption device is turned off. However, if the EC enters deep sleep, the real-time detection function cann...
