Detailed Description
The embodiment of the invention provides electronic equipment and a charging control system thereof.
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The present embodiment provides a charging control system of an electronic device, as shown in fig. 1, the charging control system of the electronic device includes a rechargeable battery 100, a detection module 200, a charging module 300, and a processor 400, wherein:
the rechargeable battery 100 has a first side 100a and a second side 100b opposite to each other. The rechargeable battery 100 may be a lithium battery, among others.
For example, as shown in fig. 2, the rechargeable battery 100 may have a cubic structure, and the first side surface 100a and the second side surface 100b may be two opposite side surfaces having the largest area among the outer surface areas of the rechargeable battery 100. Alternatively, if the rechargeable battery 100 has a cylindrical structure, the distance between the center point of the first side 100a and the center point of the second side 100b may be the diameter of the corresponding cylinder of the rechargeable battery 100, i.e., the first side 100a and the second side 100b are opposite sides of the rechargeable battery 100.
The detection module 200 may include a first capacitor plate 200a, a second capacitor plate 200b, and a capacitance detector 200c, the first capacitor plate 200a may be connected to the first side 100a, the second capacitor plate 200b may be connected to the second side 100b, and the capacitance detector 200c may be connected to the first capacitor plate 200a and the second capacitor plate 200b, respectively, to obtain capacitance information between the first capacitor plate 200a and the second capacitor plate 200 b.
At least one of the two capacitor plates (i.e., the first capacitor plate 200a and the second capacitor plate 200b) included in the detection module 200 may be a flexible deformable capacitor plate, and may generate the same deformation according to the deformation of the rechargeable battery 100. For example, as shown in fig. 1, two capacitor plates (i.e., a first capacitor plate 200a and a second capacitor plate 200b) included in the detection module 200 are respectively located on the first side 100a and the second side 100b of the rechargeable battery 100, and assuming that the two capacitor plates are both flexible and deformable capacitor plates, the two capacitor plates may generate the same deformation (including the deformation in the same direction and the same deformation amount) according to the deformation of the rechargeable battery 100 on the first side 100a and/or the second side 100 b.
As shown in fig. 3, the capacitance detector 200c may be located on a lateral surface of the rechargeable battery 100, and connected to the first capacitor plate 200a and the second capacitor plate 200b, and when the first capacitor plate 200a and/or the second capacitor plate 200b deform, the capacitance detector 200c may obtain capacitance information between the first capacitor plate 200a and the second capacitor plate 200b, where the obtained capacitance information may include a capacitance value, a capacitance variation value, and the like.
The processor 400 may be connected to the detection module 200 and the charging module 300, respectively, and the processor 400 may adjust the charging current of the rechargeable battery 100 by the charging module 300 according to the capacitance information.
During the process of charging the rechargeable battery 100, if the charging current for charging the rechargeable battery 100 is large, the rechargeable battery 100 may bulge, and the first capacitor plate 200a located on the first side surface 100a and/or the second capacitor plate 200b located on the second side surface 100b may deform correspondingly according to the bulge of the rechargeable battery 100, so as to cause a change in the relative distance between the first capacitor plate 200a and the second capacitor plate 200 b.
Since the capacitance value and the relative distance between two opposite capacitor plates (i.e., the first capacitor plate 200a and the second capacitor plate 200b) satisfy the correspondence relationship of C ═ S/d (where C is the capacitance value, and the dielectric constant ∈, S is the facing area between the first capacitor plate 200a and the second capacitor plate 200b, and d is the distance between the first capacitor plate 200a and the second capacitor plate 200b), when the distance between two capacitor plates (i.e., the first capacitor plate 200a and the second capacitor plate 200b) becomes larger, the capacitance value between the two capacitor plates also becomes smaller accordingly.
As shown in fig. 1, in the process of charging the rechargeable battery 100 by the charging module 300, if the rechargeable battery 100 bulges on the first side surface 100a (i.e. the rechargeable battery 100 can deform convexly on the first side surface 100 a), the first capacitor plate 200a connected to the first side surface 100a can deform in the same direction and in the same deformation amount according to the convex deformation of the rechargeable battery 100 on the first side surface 100a (it is assumed that the first capacitor plate 200a on the first side surface 100a of the rechargeable battery 100 is a flexible deformable capacitor plate). Since the capacitor plate on the first side 100a deforms along with the deformation of the rechargeable battery 100 on the first side 100a, the relative distance between the capacitor plate on the first side 100a of the rechargeable battery 100 and the second capacitor plate 200b on the second side 100b of the rechargeable battery 100 changes, and the capacitance information (i.e., the capacitance value) between the first capacitor plate 200a and the second capacitor plate 200b detected by the capacitance detector also changes correspondingly. At this time, the processor 400 may adjust the charging current of the rechargeable battery 100 by the charging module 300 according to the acquired capacitance information. So as to reduce the safety risk caused by the fact that the charging current cannot be accurately adjusted according to the swelling condition of the rechargeable battery 100 in the charging process.
Further, if the rechargeable battery 100 includes a plurality of first capacitor plates 200a and a plurality of second capacitor plates 200b opposite to the first capacitor plates 200a, the processor 400 may respectively acquire capacitance information between the pairs of capacitor plates based on the capacitance detector 200 c. Then, the charging current of the rechargeable battery 100 is adjusted based on the largest capacitance value or the largest capacitance change value in the capacitance information. For example, if 3 pairs of the first and second capacitor plates 200a and 200b are provided in the rechargeable battery 100. At the present time, the processor 400 may obtain the capacitance value in the capacitance information between the 3 pairs of first and second capacitance plates 200a and 200 b. Assuming that the capacitance values between the 3 pairs of the first and second capacitor plates 200a and 200b are C1, C2, and C3, respectively, the processor 400 may adjust the charging current of the rechargeable battery 100 from the charging module 300 according to the largest capacitance value of the three capacitance values.
The charging control system of the electronic device provided by the embodiment of the invention comprises a rechargeable battery, a detection module, a charging module and a processor, wherein: the rechargeable battery is provided with a first side face 100a and a second side face which are opposite, the detection module comprises a first capacitor plate, a second capacitor plate and a capacitance detection meter, the first capacitor plate is connected to the first side face, the second capacitor plate is connected to the second side face, the capacitance detection meter is respectively connected with the first capacitor plate and the second capacitor plate so as to obtain capacitance information between the first capacitor plate and the second capacitor plate, the processor is respectively connected with the detection module and the charging module, and the processor adjusts the charging current of the charging module to the rechargeable battery according to the capacitance information. The charging control system based on the electronic equipment can adjust the charging current for charging the rechargeable battery according to the capacitance information between the first capacitance polar plate and the second capacitance polar plate which are positioned on the two opposite side surfaces of the rechargeable battery in the charging process, so that the safety risk caused by bulge of the rechargeable battery in the charging process is reduced.
Example two
The embodiment of the invention provides a charging control system of electronic equipment. The charging control system of the electronic device comprises all functional units of the charging control system of the electronic device shown in fig. 1 to 3, and is improved on the basis of the functional units, and the improvement content is as follows:
as shown in fig. 4, the electronic device may have a housing, the rechargeable battery 100 may be installed in the housing, the first side 100a may be adjacent to an inner wall of the housing, the first capacitor plate 200a may be fixed between the housing and the first side 100a, and the second capacitor plate 200b may be attached to the second side 100b and movable with the second side 100 b.
If the charging current to the rechargeable battery 100 is large, which may cause the rechargeable battery 100 to deform on the second side surface 100b, the second capacitor plate 200b attached to the second side surface 100b may deform in the same direction and in the same deformation amount with the bulge of the rechargeable battery 100 (the second capacitor plate 200b may be a flexible deformable capacitor plate), so that the relative distance between the first capacitor plate 200a and the second capacitor plate 200b may be changed, that is, the capacitance information detected by the capacitance detector 200c may be changed.
In addition, when the case is in a closed state, the distance between the second capacitor plate 200b and the case needs to be greater than a preset distance threshold.
If the charging current to rechargeable battery 100 is large, it may cause rechargeable battery 100 to bulge on second side surface 100b where second capacitor plate 200b is disposed. When the case is in a closed state, if the distance between the second capacitor plate 200b and the case is smaller than the preset distance threshold, the case may extrude the rechargeable battery 100 with the bulge, which may easily cause safety problems such as battery explosion. Therefore, when the case is in a closed state, the distance between the second capacitor plate 200b and the case needs to be greater than the predetermined distance threshold.
The capacitance information may include a capacitance value between the first capacitor plate 200a and the second capacitor plate 200b, and the processor 400 may control the charging module 300 to decrease the charging current to the first safe current I when the capacitance value is less than or equal to a preset safe capacitance value1。
For example, if the capacitance value is greater than the preset capacitance safety threshold, it indicates that the charging current does not cause deformation of the rechargeable battery 100 (i.e., the rechargeable battery 100 does not bulge), and the charging current may not be adjusted at this time, and the rechargeable battery 100 is still charged by the current charging current. If the capacitance value is smaller than the preset capacitor safety threshold value, it indicates that the rechargeable battery 100 is currently in the bulge state, and the preset amplitude of the charging current may be adjusted to avoid increasing the bulge degree of the rechargeable battery 100.
The capacitance information may include a capacitance variation of the capacitance between the first capacitor plate 200a and the second capacitor plate 200b in a predetermined time, and the processor 400 may further adjust the charging current of the charging module 300 according to the capacitance variation when the capacitance is less than or equal to a preset safe capacitance.
The predetermined time may be any time, for example, 30ms, 1s, 5s, or the like.
In a case that the capacitance value is less than or equal to the preset safe capacitance value, after the capacitance value is obtained, the processor 400 may determine, based on the stored capacitance value, a variation of the capacitance value at the current time within a predetermined time, and then may adjust the charging current of the charging module 300 according to the variation.
For example, the capacitance value obtained at the current time is C1, and C1 is smaller than the preset safety capacitor, the processor 400 may obtain the stored capacitance value before 1s (C2), determine the variation of the capacitance value within 1s at the current time according to the difference between C1 and C2, and may adjust the charging current of the rechargeable battery 100 according to the variation.
In the case that the capacitance value is less than or equal to the preset safe capacitance value, the processor 400 may determine the current safety level corresponding to the capacitance variation according to the preset corresponding relationship between the capacitance variation and the current safety level, and the charging module 300 may adjust the charging current according to the current safety level.
If the capacitance variation is large, it indicates that the deformation amplitude of the rechargeable battery 100 in the predetermined time is large, and the corresponding current safety level is low. A major safety issue may arise if the rechargeable battery 100 is still charged at the present charging current.
When the capacitance value is less than or equal to the preset safe capacitance value and the capacitance variation is less than or equal to the preset safe capacitance variation, the processor 400 may control the charging module 300 to reduce the charging current to the second safe current I2Wherein the second safety current I2Less than the first safetyStream I1。
After the current is reduced to a second safe current I2After the first preset time, under the condition that the capacitance value is less than or equal to the preset safe capacitance value and the capacitance variation is less than or equal to the preset safe capacitance variation, the processor 400 may control the charging module 300 to reduce the charging current to the third safe current I3Wherein the third safety current I3Less than a second safety current I2。
First safety current I1A second safety current I2And a third safety current I3Can satisfy the following conditions: i is1＝0.8I0，I2＝0.6I0，I3＝0.4I0In which I0Is the rated charging current.
After the current is reduced to a third safe current I3After the second preset time, under the condition that the capacitance value is less than or equal to the preset safe capacitance value and the capacitance variation is less than or equal to the preset safe capacitance variation, the controller may control the charging module 300 to stop charging the rechargeable battery 100, and meanwhile, the controller may also control the electronic device to send a prompt message prompting that the battery is overheated. Or the controller may control the electronic device to send a prompt message indicating that the battery is overheated, receive a charging stop operation of the user, and then control the charging module 300 to stop charging the rechargeable battery 100 in response to the charging stop operation, so as to avoid safety problems such as battery explosion.
The second preset time may be less than the first preset time.
The charging control system of the electronic device provided by the embodiment of the invention comprises a rechargeable battery, a detection module, a charging module and a processor, wherein: the rechargeable battery is provided with a first side face and a second side face which are opposite, the detection module comprises a first capacitor plate, a second capacitor plate and a capacitance detection meter, the first capacitor plate is connected to the first side face, the second capacitor plate is connected to the second side face, the capacitance detection meter is respectively connected with the first capacitor plate and the second capacitor plate so as to obtain capacitance information between the first capacitor plate and the second capacitor plate, the processor is respectively connected with the detection module and the charging module, and the processor adjusts the charging current of the charging module to the rechargeable battery according to the capacitance information.
