Embodiment
Below in conjunction with embodiment, be described in further detail the present invention.These embodiments are illustration of the present invention, the claim scope that is not meant to limit the present invention.
In this process, for clarity and the convenience that illustrates, the line weight on accompanying drawing or the size of inscape etc. may be exaggerated demonstration.In addition, be to consider the function in the present invention and the term that defines with the term that occurs in the narration of back, this can change according to intention or convention of user, network operator.Therefore, the definition of these terms should be take the content in whole instructions as the basis.
Fig. 1 is the key diagram that consists of of battery sensor for automobile according to an embodiment of the invention, and Fig. 2 is the SOC mapping table of battery sensor for automobile according to another embodiment of the present invention.
As shown in Figure 1, battery sensor for automobile comprises according to an embodiment of the invention, battery 1 and control part 2 and battery sensor (IBS: Intelligent Battery Sensor) 3.
As shown in Figure 2, battery sensor 3 detects electric current, voltage, temperature, SOC (state of charge) etc., offers control part 2.
These battery sensors 3 are under normal (Normal) pattern, detect power consumption-15mA, electric current, voltage, temperature, SOC etc., under sleep (Sleep) pattern, detect power consumption-150uA, be waken up (wake up) every 15 minutes and detect electric current, voltage, temperature in 100 milliseconds.In 1 ~ 15 minute, the dark current of automobile is waken up by interrupting function during greater than the threshold electric current.
But, install and to pull out again after inserting accessory on the automobile of battery sensor 3, or insert the power consumption accessory less than original accessory (such as: in the time of power consumption 200mA), the threshold current value that ought to reduce sometimes can not reduce.
At this moment, battery sensor 3 is not waken up when should being waken up, so the power consumption miscount may occur.
The accumulation meeting of such power consumption miscount causes fatal problem to residual capacity of battery.In other words, the residual capacity of battery of meeting cumulative error.Along with the automobile increase of tenure of use, mistake can continue accumulation.
Through wrong accumulation, battery sensor 3 passes to control part 2 with the battery information of mistake, causes control part 2 actions to make mistakes.
Therefore, the present invention will provide battery sensor and control method, in order to improve contingent battery power consumption miscount when plugging outside appurtenances from automobile when stopping.
At this, less than the threshold electric current, by after control part 2 change threshold electric currents, battery sensor is placed in sleep pattern when dark current, greater than the threshold electric current, battery sensor 3 is placed in normal mode when dark current.
Fig. 3 is for illustrating according to an embodiment of the invention the precedence diagram of automotive battery inducing method, and Fig. 4 is for illustrating according to an embodiment of the invention the process flow diagram of IBS action.
As shown in Figure 3 and Figure 4, automotive battery inducing method according to an embodiment of the invention, at first (S10) detects the dark current of automobile in special time after switch-off, according to the variation of detecting dark current whether, and the plug (S20) of judgement outside appurtenances.
When being judged as the accessory plug, dark current and the threshold electric current that detects in special time compared (S30).
At this moment, the dark current that detects in special time adds 5% of current dark current during less than the threshold electric current, change threshold electric current (S40).
After change threshold electric current, through the specific time, can again battery sensor be placed in sleep pattern (S50).
Then, the dark current that detects in special time is placed in battery sensor normal mode (S60) greater than the threshold electric current.
Such as, pull out from the automobile that IBS is installed during parking original accessory (such as: in the time of the 300mA power consumption), after finding that by the variation of dark current in the induction special time accessory is pulled out, threshold electric current (automobile dark current X 5%) is adjusted into 315mA.Then, IBS is placed in sleep pattern.
After, (for example: in the time of 500 mA power consumptions), after finding new accessory by the variation of induction dark current, greater than the threshold electric current, IBS is placed in normal mode when the dark current that detects insert new accessory.
After then battery sensor being placed in normal mode, threshold electric current (automobile dark current X 5%) is adjusted into 525mA.Then, through after special time, again battery sensor is placed in sleep pattern.
As mentioned above, the present invention detects the dark current that changes along with the plug of outside appurtenances after switch-off, after change threshold electric current, battery sensor is placed in sleep pattern, so can improve battery power consumption miscount.
Above in conjunction with description of drawings of the present invention embodiments of the present invention.But the practitioner of the technical field of the invention is to be understood that and can also has other the embodiment that need not to change its technological thought or indispensable characteristics.Therefore, embodiment of the present invention is all exemplary in all respects, and is not confined to this.Scope of the present invention delimited by claims, and all changes of deriving in the meaning of claims and scope and equivalent concepts thereof in addition or the form of distortion all should be understood to belong to category of the present invention.
