The RBLT value correction method for the battery can be suitable for electronic equipment with longer connecting lines between the battery and a circuit board, such as VR head-mounted products, intelligent helmets and the like. The embodiment of the present application is described with an example of being applied to a VR headset.
When the VR headset is worn on the head of a user during use, most parts such as a display device and a circuit board for realizing the functions of the VR headset are usually arranged at positions close to the eyes of the user, which results in a heavy VR headset near the eyes of the user. For the weight of balanced VR head-mounted device, can be close to the position of user's back brain on VR head-mounted device for the battery setting of VR head-mounted device power supply to balanced VR head-mounted product holistic weight, so that the user when wearing VR head-mounted product, can not produce before the VR head-mounted device heavy back light, can make the user have the use of preferred and experience. However, the above structure can cause the distance between the battery and the main board electrically connected with the battery to be too long, so that the voltage drop between the battery and the main board is improved, the RBLT value of the battery collected by the main board is inaccurate, and the battery cannot respond to the service condition of the battery timely and accurately.
In order to obtain an accurate RBLT value of a battery, in the embodiment of the application, a real-time current value of the battery is obtained first, and the real-time current value is corrected to obtain a corrected current value.
During the charging and discharging process of the battery, the current of the battery can greatly shake, and the calculation of the RBLT value of the battery can be directly influenced by the large-amplitude shaking of the current of the battery. In order to reduce the influence of large-amplitude jitter of the battery current on the calculation of the RBLT value of the battery, the current of the battery is corrected first in the embodiment of the application, so that the RBLT value of the battery can be corrected more accurately.
In this embodiment, the instantaneous current of the battery is collected to obtain the real-time current value of the battery, and then the real-time current value is corrected to obtain the corrected current value.
And obtaining a first voltage drop according to the correction current value and the impedance of the connecting line.
In the embodiment of the present application, the corrected current value is already obtained by correcting the real-time current value, and the impedance of the connection line is directly obtainable, that is, the corrected current value and the impedance of the connection line are both known values. The voltage consumed by the connecting line after the real-time current is corrected, that is, the first voltage drop in the embodiment of the present application, can be obtained by multiplying the corrected current value by the impedance of the connecting line. The resulting first pressure drop provides an advantage for subsequently obtaining a corrected RBLT value.
And acquiring a real-time RBLT value of the battery, and acquiring a corrected RBLT value according to the real-time RBLT value and the first voltage drop.

According to the battery management system and the battery management method, the battery RBLT value is corrected through the real-time RBLT value of the battery, the deviation of the battery RBLT value is reduced, the mainboard can make accurate judgment on the use state of the battery, and the use experience of a user is improved.
Optionally, the obtaining a real-time current value of the battery, and correcting the real-time current value to obtain a corrected current value includes:
and obtaining the correction current value according to the functional relation between the real-time current value and the correction current value.
Although the real-time current value can greatly jitter, the real-time current value of each product has the same factor of large jitter, that is, the jitter of the real-time current value conforms to a certain rule. And after the real-time current value is obtained, calculating the correction current value according to the functional relation between the real-time current value and the correction current value, thereby realizing the correction of the real-time current value. The correction of the real-time current value can be more accurate.
In the embodiment of the application, the functional relationship between the real-time current value and the correction current value is determined in advance, and then the functional relationship between the real-time current value and the correction current value is written into an algorithm. When the RBLT value of the battery is corrected, after the real-time current value is obtained, the corrected current value can be accurately and quickly obtained through the functional relation between the real-time current value and the corrected current value written in the algorithm.

and obtaining a second voltage drop according to the real-time current value and the impedance of the connecting line.
The real-time current value can be obtained through direct detection, and the impedance of the connecting line can be directly obtained, namely the real-time current value and the impedance of the connecting line are both known values. The real-time current value is multiplied by the impedance of the connection line, and the voltage actually consumed by the connection line, i.e., the second voltage drop in the embodiment of the present application, can be obtained. The second voltage drop obtained provides an advantage for subsequently obtaining a functional relationship between the real-time current value and the correction current value.
In the embodiment of the application, the real-time current value is multiplied by the impedance of the connecting line, so that the second voltage drop can be obtained.
And obtaining a target RBLT value according to the second pressure drop and the real-time RBLT value.
In the embodiment of the application, the battery real-time RBLT value is acquired, and then the second voltage drop calculated in the above step is compensated to the acquired battery real-time RBLT value, so that the target RBLT value can be obtained.

real-time RBLT value-real-time RBLT value (second drop/preset voltage) = target RBLT value.
When the equipment is charged, the voltage at the Ground (GND) end is pulled high, then the reading value of the RBLT is larger, and the reading value of the RBLT is corrected by deducting a second voltage drop from the reading value, namely, subtracting the second voltage drop from a preset voltage; when the voltage at Ground (GND) of the device is pulled down when discharging, the RBLT reading value is small, and the correction algorithm needs to compensate the value of the second voltage drop to the RBLT value, namely, the preset voltage plus the second voltage drop. Since the battery current has a positive and negative component in the charging and discharging process, it can be summarized as follows: real-time RBLT value-real-time RBLT value (second drop/preset voltage) = target RBLT value. The real-time mode can accurately obtain the target RBLT value, and provides favorable conditions for obtaining the functional relationship between the real-time current value and the correction current value subsequently.
Optionally, the obtaining a functional relationship between the real-time current value and the correction current value according to the target current value and the real-time current value includes:

That is, in the present embodiment, a most suitable functional relationship between the target current value and the real-time current value can be obtained by obtaining a plurality of functional relationships between the target current value and the real-time current value and fitting the obtained plurality of functional relationships, so that the calculated correction current value is moderate, and is neither large nor small.
For example, ten groups of the target current values and the real-time current values are obtained, and each group of the target current values and the real-time current values can obtain a functional relationship between one target current value and one real-time current value, so that ten functional relationships can be formed. Fitting the ten functional relations to obtain a proper functional relation, and writing the proper functional relation into an algorithm to participate in the calculation of the corrected RBLT value.
Optionally, the deriving a corrected RBLT value based on the real-time RBLT value and the first pressure drop comprises:
real-time RBLT value-real-time RBLT value (first drop/preset voltage) = corrected RBLT value.
When the equipment is charged, the voltage at the Ground (GND) end is pulled high, then the RBLT reading value is larger, and the first voltage drop is required to be deducted from the RBLT reading value for correction, namely the first voltage drop is subtracted from the preset voltage; when the voltage at Ground (GND) of the device is pulled down when discharging, the read value of RBLT is small, and the correction algorithm needs to compensate the value of the first voltage drop to the value of RBLT, namely, the preset voltage plus the first voltage drop. Since the battery current has a positive and negative component in the charging and discharging process, it can be summarized as follows: real-time RBLT value-real-time RBLT value (first drop/preset voltage) = corrected RBLT value. The real-time mode can accurately obtain the corrected RBLT value.
Optionally, the deriving a corrected RBLT value based on the real-time RBLT value and the first pressure drop comprises:

Optionally, the debouncing the corrected RBLT value, and obtaining the debounced RBLT value includes:
and obtaining a plurality of corrected RBLT values, and processing the corrected RBLT values through a median average filtering algorithm to obtain an anti-shake RBLT value.

Of course, the number of resulting corrected RBLT values may not be limited to ten, and may be greater, e.g., fifteen, twenty, etc., while ensuring data smoothness.
