Electron system for managing battery capacity and related method

Abstract

The removable battery module can be installed in a system module to cooperate the system module for charging or discharging so as to supply electric energy to the system module or take electric energy from the system module to be stored. A device for measuring electric quantity is setup in the system module to record the electric quantity transferred between the system module and the battery module. A storage device is setup in the battery module to record data of electric quantity stored in the battery module. When the battery module charges or discharges the system module, the system module calculates out new electric quantity after charging or discharging of the battery module based on recorded data of electric quantity in storage, as well as updates the data of electric quantity in the storage.

Description

Technical field: [0001] The invention provides an electronic system and a related method for managing battery power, especially an electronic system and a related method for managing battery power by using a power detection device of the system itself in conjunction with a detachable battery storage device. Background technique [0002] In modern society, many electronic products can use the electric energy stored in the battery to provide the energy required for operation, so that users can get rid of the shackles and restrictions of power supply lines. However, the power stored in the battery will be gradually consumed with the operation of the electronic product, and eventually it will not be able to supply power normally. To keep the electronic product running normally, it is necessary to have a certain battery power management mechanism, so that the user can control the battery power In order to take appropriate countermeasures (such as storing data early or replacing a...

Problems solved by technology

When the user replaces the battery module 45 and uses the battery module 44 with 95% capacity to power the system module 42 again, even the power management device 46 can recognize that the battery module connected to the power port 50A has been replaced by the battery module. 45 is changed back to the battery module 44, but it is still difficult to judge that the power of the battery module 44 has increased from 20% to 95%

in this case, figure 2 It is also difficult for the medium battery power management mechanism to effectively manage the real power of the battery module

[0011] Looking at the above two known technologies, the electronic system 10 ( Figure 1A , The cost of the battery power management mechanism in 1B) is relatively high, and it is difficult to popularize and use

While the electronic system 40 ( figure 2 ) in the battery power management mechanism is more difficult to grasp the actual power of each battery module, the two battery power management mechanisms are not ideal
