[detailed description of the invention]
Fig. 1 is schematically shown as the block chart of the electronic installation of present invention application battery protecting method.Fig. 2 is schematically shown as the flow chart of one embodiment of the invention battery protecting method.Please merge and see figures.1.and.2.Electronic installation 10 includes battery 110, system 120 and controller 130.Controller 130 is coupled to system 120 and battery 110.
In the present embodiment, controller 130 can be KBC (keyboard controller, KBC) or embed controller (embedded controller, EC), but the present invention is not limited, in actual design or application demand.Battery 110 includes power management chip 112 and battery 114.Power management chip 112 can be used for detecting temperature and the battery capacity of battery 114, so as to providing Temperature numerical X_TEMP and battery capacity numerical value X_CAPA to controller 130.
Specifically, the guard method for battery 110 includes that following steps is rapid.
First, as shown in step S201, Temperature numerical X_TEMP and the battery capacity numerical value X_CAPA of battery 110 can be read by controller 130.
Then, as shown in step S203, can be judged whether Temperature numerical X_TEMP and battery capacity numerical value X_CAPA exceed preset critical by controller 130.Such as, when Temperature numerical X_TEMP more than 70 DEG C and battery capacity numerical value X_CAPA exceed rated cell capacity 80% time, then controller 130 can determine whether as alreading more than preset critical.Note that the numerical value of preset critical is not limited with above-described embodiment, in actual design or application demand.
If Temperature numerical X_TEMP and battery capacity numerical value X_CAPA exceed preset critical, then enter step S205.In step S205, the on-off state of system 120 can be determined whether by controller 130.If system 120 is for open state, enter step S207, if system 120 is for off-mode, enter step S211.
As shown in step S207, when system 120 is open state, the first electric discharge kenel can be determined as further by controller 130.Subsequently enter step S209, according to the first electric discharge kenel described battery 110 of electric discharge.
As shown in step S211, when system 120 is off-mode, the second electric discharge kenel can be determined as further by controller 130.Subsequently enter step S213, according to the second electric discharge kenel described battery 110 of electric discharge.The first, the second electric discharge kenel with actual should be used for design.
On the other hand, in step S209 or step S213, when controller 130 is according to corresponding electric discharge kenel electric discharge described battery 110, system 120 does not produce any meeting allows user learn the information that battery 110 is discharging.Such as, in step S213, system is off-mode, by battery 110 being supplied electricity to load circuit (load circuit can be such as DC-DC voltage converter, internal storage location or USB (universal serial bus) circuit), and during this discharges, be not turned on screen, therefore process of this electric discharge will not show any information through screen and allow user learn battery 110 discharges.Such as, in step S209, system 120 is open state, although battery 110 starts the system that supplies electricity to 120 or load circuit 122, but still shows that the power source of this system 120 is AC power supplies at screen, and does not show that real electric discharge source is battery 110.
At this it is noted that owing to electronic installation 10 is under the shutdown or open state of system 120, whether controller 130 can exceed preset critical according to Temperature numerical X_TEMP and battery capacity numerical value X_CAPA is protected battery.Therefore, no matter electronic installation 10 is at the off-mode of system 120 or open state, can avoid the battery 110 in high temperature environments may leakage or the phenomenon of expansion.
Based on the content disclosed in above-described embodiment, another embodiment can be derived.Fig. 3 is schematically shown as the flow chart of another embodiment of the present invention battery protecting method.Please merge with reference to Fig. 1 and Fig. 3.
First, as shown in step S301, Temperature numerical X_TEMP and the battery capacity numerical value X_CAPA of battery 110 can be read by controller 130.
Then, as shown in step S303, can be judged whether Temperature numerical X_TEMP and battery capacity numerical value X_CAPA exceed preset critical by controller 130.Such as, in an environment of high temperature, Temperature numerical X_TEMP can be more than 70 DEG C.When Temperature numerical X_TEMP more than 70 DEG C and battery capacity numerical value X_CAPA exceed rated cell capacity 80% time, then controller 130 can determine whether as alreading more than preset critical.Note that the numerical value of preset critical is not limited with above-described embodiment, in actual design or application demand.
If Temperature numerical X_TEMP and battery capacity numerical value X_CAPA exceed preset critical, then enter step S305.In step S305, the on-off state of system 120 can be determined whether by controller 130.If system 120 is for entering step S307 during open state, if system 120 is for entering step S311 during off-mode.
As shown in step S307, when system 120 is open state, external power source 140 can be limited by controller 130 and supply power to system 120.Such as forbid that the conversion electric power of AC-DC inputs to system 120.Subsequently enter step S309, battery 110 supply electric power to system 120 with the described battery 110 that discharges.Consequently, it is possible at high temperature battery 110 is discharged, contribute to reducing the speed of the chemical change of battery 110 and slowing down speed of expansion, and cell damage can be avoided.
On the other hand, as shown in step S311, when system 120 is off-mode, the load circuit 122 of system 120 can be started by controller 130.Such as, load circuit 122 can be DC-DC voltage converter (DC-DC voltage converter), internal storage location (memory cell) or USB (universal serial bus) (universal serial bus, USB) circuit, but the present invention is not limited.Subsequently enter step S313, with the electric power of described battery 110 supply load circuit 122, so as to the described battery 110 that discharges, thus the leakage of battery 110 in high temperature environments, expansion or the infringement of the not reversibility such as on fire can be avoided.
Additionally, in step S309 or step S313, system 120 does not produce any meeting allows user learn the information that battery 110 is discharging.Such as, in step S313, system is off-mode, by battery 110 being supplied electricity to load circuit (load circuit can be such as DC-DC voltage converter, internal storage location or USB (universal serial bus) circuit), and during this discharges, be not turned on screen, therefore process of this electric discharge will not show any information through screen and allow user learn battery 110 discharges.Such as, in step S309, system 120 is open state, although battery 110 starts the system that supplies electricity to 120 or load circuit 122, but still shows that the power source of this system 120 is AC power supplies at screen, and does not show that real electric discharge source is battery 110.
Even, when system 120 is open state and described battery 110(step S309 of discharging) time, system 120 also can be showed more than the high temperature alert news of the system specification to user, it is dangerous so as to reminding user at high temperature to operate electronic installation 10, or the self character to battery 110 is harmful.
In sum, owing to electronic installation is under the shutdown or open state of system, whether controller can exceed preset critical according to Temperature numerical and battery capacity numerical value is protected battery, especially for the battery in non-usage.Therefore, no matter electronic installation is at the off-mode of system or open state, can avoid in high temperature environments battery may leakage, expansion or the phenomenon such as on fire, thus increase the safety of system or the safety of user.
