Modes for Carrying Out the Invention

[0039] In the description of this application, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above and obliquely above the second feature, with the first feature having a higher horizontal height than the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, with the first feature having a lower horizontal height than the second feature.

[0041] In the description of this embodiment, terms such as "upper," "lower," "left," "right," "front," and "rear" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and do not have any special meanings.

[0042] To protect battery safety, batteries must not be overcharged or over-discharged during use. Furthermore, internal status monitoring of the battery's various physical environments is required. Related technologies typically use a data processing chip to receive data collected by sensors such as temperature and pressure. The data processing chip processes the received data and transmits it to an external terminal to monitor the battery's internal status.

[0043] There are currently two ways to set up the data processing chip and the battery cell. The first is to connect the data processing chip and the battery cell in series, with the battery cell powering the data processing chip. However, in this way, when the data processing chip is damaged, the positive and negative poles of the battery cell will be directly connected, causing a short circuit. The second is that the battery cell does not power the data processing chip. However, in this way, when the data processing chip is exhausted, it cannot be effectively charged, resulting in the data processing chip being unable to monitor the stability of the internal state of the battery.

[0044] The present application provides a battery. The battery may be a lithium battery. Referring to Figures 1 to 3, the battery 100 includes:

[0045] The battery cell 10 ; the data processing chip 20 ; and the charging protector 30 , which is electrically connected to the battery cell 10 and the data processing chip 20 and configured to control the on / off of the circuit connecting the battery cell 10 and the data processing chip 20 .

[0046] When the voltage of the data processing chip 20 is greater than a preset value, the circuit connecting the data processing chip 20 and the battery cell 10 in the charging protector 30 is disconnected; when the voltage of the data processing chip 20 is less than a preset value, the circuit connecting the data processing chip 20 and the battery cell 10 in the charging protector 30 is connected.

[0047] In the present application, the charging protector 30 is electrically connected to the battery cell 10 and the data processing chip 20. When the data processing chip 20 is fully charged, the voltage of the data processing chip 20 is greater than a preset value, and the circuit connecting the data processing chip 20 and the battery cell 10 in the charging protector 30 is disconnected. At this time, the battery cell 10 stops charging the data processing chip 20. When the data processing chip 20 is insufficiently charged, the voltage of the data processing chip 20 is less than a preset value, and the circuit connecting the data processing chip 20 and the battery cell 10 in the charging protector 30 is connected. At this time, the battery cell 10 starts charging the data processing chip 20. By providing the charging protector 30, the battery cell 10 is prevented from continuously charging the data processing chip 20, resulting in overcharging, or from short-circuiting the battery cell 10 due to damage to the data processing chip 20, thereby extending the service life of the battery cell 10. At the same time, when the data processing chip 20 is insufficiently charged, the charging protector 30 can charge the data processing chip 20 through the battery cell 10, thereby improving the technical problem that the data processing chip 20 cannot stably monitor the internal state of the battery 100 due to insufficient power.

[0048] During the charging process of the data processing chip 20, the preset voltage value of the data processing chip 20 is set with reference to the rated voltage and full-charge voltage of the data processing chip 20. For example, if the rated voltage of the data processing chip 20 is 3.7V and the overcharge protection voltage is 4.2±0.05V, the preset voltage value of the data processing chip 20 is within the range of 3.7V-4.25V.

[0049] During the discharge of the data processing chip 20, the voltage preset value of the data processing chip 20 is set with reference to the rated discharge voltage of the data processing chip 20. For example, if the over-discharge protection voltage of the data processing chip 20 is 2.3V, the voltage preset value of the data processing chip 20 is within the range of 2.3V-2.4V.

[0050] The data processing chip 20 is configured to receive data collected by other sensors inside the battery cell 10 and transmit the collected data to an external terminal.

[0051] The battery 100 also includes a display panel, which is arranged on the outside of the battery 100. The data processing chip 20 is electrically or wirelessly connected to the display panel. The data processing chip 20 transmits the collected data to the display panel. The display panel receives the data collected by the data processing chip 20 and displays it on the screen, so as to intuitively monitor the internal pressure and temperature information of the battery 100, thereby improving the safety performance of the battery 100.

[0052] Continuing to refer to Figures 1 to 3, in one embodiment, the battery cell 10 includes a first electrode 11 and a second electrode 12; the data processing chip 20 includes a first data pin and a second data pin; the first electrode 11 is electrically connected to the first data pin, the second electrode 12 is electrically connected to the charging protector 30, and the second data pin is electrically connected to the charging protector 30.

[0053] In some possible implementations, the first electrode 11 is one of the positive and negative electrodes of the battery cell 10, and the second electrode 12 is the other of the positive and negative electrodes of the battery cell 10. When the second data pin of the data processing chip 20 is electrically connected to the charging protector 30, the first data pin of the data processing chip 20 is electrically connected to one of the positive and negative electrodes of the battery cell 10. When the voltage of the data processing chip 20 is greater than a preset value, the circuit connecting the second electrode 12 and the second data pin in the charging protector 30 is disconnected; when the voltage of the data processing chip 20 is less than a preset value, the circuit connecting the second electrode 12 and the second data pin in the charging protector 30 is connected. When the data processing chip 20 is low on power, the charging protector 30 can charge the data processing chip 20 through the battery cell 10, thereby improving the technical problem that the data processing chip 20 cannot stably monitor the internal state of the battery 100 due to insufficient power.

[0054] 1 to 3 , in one embodiment, the charging protector 30 includes:

[0055] The switch transistor 31 is electrically connected to the second electrode 12 and the second data pin; the protection chip 32 is electrically connected to the data processing chip 20.

[0056] When the voltage of the data processing chip 20 is greater than a preset value, the switch transistor 31 is in a closed state; when the voltage of the data processing chip 20 is less than the preset value, the switch transistor 31 is in an open state.

[0057] In some possible implementations, the switching transistor 31 is one of a field effect transistor (FET), a junction field effect transistor (JFET), an N-channel JFET, a P-channel JFET, a metal oxide semiconductor field effect transistor (MOSFET), an N-channel MOSFET, a P-channel MOSFET, a small signal transistor, a small switching transistor 31, a power transistor, a high-frequency transistor, a phototransistor, and a unijunction transistor (UJT). The protection chip 32 is configured to monitor the instantaneous voltage value of the data processing chip 20. When the instantaneous voltage value of the data processing chip 20 is greater than a preset value, the switching transistor 31 is turned off. When the instantaneous voltage value of the data processing chip 20 is less than the preset value, the switching transistor 31 is turned on.

[0058] The protection chip 32 is electrically connected to the switch transistor 31 and is configured to control the switch transistor 31 to be turned on or off; alternatively, the protection chip 32 is a wireless transceiver chip and controls the switch transistor 31 to be turned on or off by wireless transceiver.

The third protection pin of the protection chip 32 is electrically connected to the gate of the NMOS transistor and is configured to control whether the NMOS transistor is turned on or off.

[0064] At this time, the NMOS tube is connected in series between the battery cell 10 and the data processing chip 20. When the voltage of the data processing chip 20 is less than a preset value, the NMOS tube is in an open state, the circuit between the battery cell 10 and the data processing chip 20 is connected, and the battery cell 10 charges the data processing chip 20; when the voltage of the data processing chip 20 is greater than the preset value, the NMOS tube is in a closed state, the circuit between the battery cell 10 and the data processing chip 20 is disconnected, and the battery cell 10 stops charging the data processing chip 20.

[0065] 5 to 7 , in one embodiment, the switching transistor 31 includes a source, a drain, and a gate; the protection chip 32 includes a first protection pin, a second protection pin, a third protection pin, and a fourth protection pin; wherein the second electrode 12 is electrically connected to one of the source and the drain, the first protection pin is electrically connected to the other of the source and the drain, the second protection pin is electrically connected to the second data pin, the third protection pin is electrically connected to the first data pin, and the fourth protection pin is electrically connected to the gate.

[0066] In some possible implementations, the switching transistor 31 is an NMOS transistor, and the protection chip 32 is model DW01. The second electrode 12 is electrically connected to one of the source and drain of the NMOS transistor, and the first protection pin is electrically connected to the other of the source and drain of the NMOS transistor. The second and third protection pins of the protection chip 32 are electrically connected to the second and first data pins of the data processing chip 20, respectively, and are configured to monitor the instantaneous voltage of the data processing chip 20. The fourth protection pin of the protection chip 32 is electrically connected to the gate of the NMOS transistor and is configured to control whether the NMOS transistor is turned on or off.

[0067] At this time, the NMOS tube and the protection chip 32 are connected in series between the battery cell 10 and the data processing chip 20. When the voltage of the data processing chip 20 is lower than the preset value, the NMOS tube is in the open state, the circuit between the battery cell 10 and the data processing chip 20 is connected, and the battery cell 10 charges the data processing chip 20; when the voltage of the data processing chip 20 is higher than the preset value, the NMOS tube is in the closed state, the circuit between the battery cell 10 and the data processing chip 20 is disconnected, and the battery cell 10 stops charging the data processing chip 20.

The elastomer is arranged at the position where the outer surface of the battery cell 10 expands and deforms, and the strain gauge is attached to the elastomer. When the elastomer is deformed due to the expansion of the battery cell 10, the strain gauge converts the deformation of the elastomer into a resistance signal. The data processing chip 20 is electrically connected to the strain gauge. The data processing chip 20 obtains the deformation of the battery cell 10 by collecting the resistance data of the strain gauge. The design of the pressure sensor 40 improves the safety performance of the battery 100.

The data processing chip 20 acquires resistance data from the thermistor to obtain the surface temperature of the battery cell 10. The provision of the temperature sensor 50 improves the safety performance of the battery 100.

One end of the first connecting cable 2003 is connected to the first adapter fixture 2002, and the other end of the first connecting cable 2003 (i.e., the end away from the first adapter fixture 2002) is connected to the data processing chip 20. One end of the second connecting cable 2004 is connected to the second adapter fixture 2005, and the other end of the second connecting cable 2004 (i.e., the end away from the second adapter fixture 2005) is connected to the data processing chip 20.

[0091] The other end of the first connecting line 2003 can be directly connected to the data processing chip 20, or it can be connected to the charging protector 30 or other device, thereby indirectly connecting to the data processing chip 20 through the charging protector 30 or other device. Similarly, the other end of the second connecting line 2004 can be directly connected to the data processing chip 20, or it can be connected to the charging protector 30 or other device, thereby indirectly connecting to the data processing chip 20 through the charging protector 30 or other device.

[0092] In some possible implementations, the material of the first adapter clamp 2002 and the first connecting wire 2003 can be a conductive material such as aluminum, and the first connecting wire 2003 is wrapped with an insulating layer. The material of the second connecting wire 2004 can be a conductive material such as copper, and the second connecting wire 2004 is wrapped with an insulating layer. The material of the second adapter clamp 2005 is a conductive material such as copper.

[0093] In some possible implementations, as shown in Figure 15, the first adapter clamp 2002 includes a first support arm 501 and two first clamping arms 502 respectively connected to the first support arm 501, and the two first clamping arms 501 are positioned opposite to each other, and the ends of the two first clamping arms 502 away from the first support arm 501 are close to each other, and the two first clamping arms 502 are clamped on both sides of the positive electrode connecting plate 1005.

[0094] Similarly, the second adapter clamp 2005 can include a second support arm and two second clamping arms respectively connected to the second support arm, the two second clamping arms are positioned opposite to each other, the two second clamping arms are close to each other at one end away from the second support arm, and the two second clamping arms are clamped on both sides of the negative electrode connecting plate 1004.

[0095] By using the two first clamping arms 502 of the first adapter clamp 2002 to clamp the positive connecting piece 1005, and using the two second clamping arms of the second adapter clamp 2005 to clamp the negative connecting piece 1004, the friction between the first adapter clamp 2002 and the positive connecting piece 1005, and the friction between the second adapter clamp 2005 and the negative connecting piece 1004 is increased, so that when the battery 100 shakes, the first adapter clamp 2002 and the positive connecting piece 1005, and the second adapter clamp 2005 and the negative connecting piece 1004 are less likely to fall off.

[0096] In some possible implementations, as shown in Figure 18, a first wire hole 504 is provided on the first support arm 501 of the first adapter clamp 2002, and a second wire hole is provided on the second support arm of the second adapter clamp 2005; wherein, one end of the first connecting wire 2003 is fixed in the first wire hole 504, and one end of the second connecting wire 2004 is fixed in the second wire hole.

[0097] As shown in Figure 19, by respectively providing a first wire hole 504 on the first support arm 501 and a second wire hole on the second support arm, the first connecting wire 2003 can be connected to the first adapter clamp 2002 and the second adapter clamp 2005 through the first wire hole 504, and the second connecting wire 2004 can be connected to the second adapter clamp 2005 through the second wire hole, thereby ensuring the stability between the first adapter clamp 2002 and the first connecting wire 2003, and the second adapter clamp 2005 and the second connecting wire 2004.

[0098] It should be noted that the first wire hole 504 and the second wire hole can be set at other positions on the first support arm 501 and the second support arm respectively according to specific circumstances. The above examples are only for better illustrating this solution, rather than limiting this solution.

[0099] In some possible implementations, as shown in FIG15 , one first clamping arm 502 of the first adapter clamp 2002 extends from the first support arm 501 along a first direction, and the other first clamping arm 502 extends from the first support arm 501 along a second direction, with the first direction and the second direction intersecting. The structure of the second adapter clamp 2005 is identical to that of the first adapter clamp 2002 and will not be further described herein.

[0100] The extension lines of the two first clamping arms 502 of the first adapter clamp 2002 and the two second clamping arms of the second adapter clamp 2005 intersect, and the angle formed by the intersection is an acute angle, so that the first adapter clamp 2002 and the second adapter clamp 2005 can be clamped on the positive connecting piece 1005 and the negative connecting piece 1004 respectively without slipping.

[0101] In some possible implementations, as shown in FIG20 , the end of the first clamping arm 502 away from the first support arm 501 is clamped within the first groove 1101, and the end of the second clamping arm away from the second support arm is clamped within the second groove. By clamping the first clamping arm 502 and the second clamping arm within the first groove 1101 and the second groove, respectively, the first clamping arm 502 and the second clamping arm can be respectively stuck in the first groove 1101 and the second groove, further increasing the stability of the connection between the first adapter clamp 2002 and the positive electrode connecting tab 1005, and the second adapter clamp 2005 and the negative electrode connecting tab 1004.

[0102] In some possible implementations, as shown in FIG16 , the first adapter clamp 2002 further includes a first clamping arm 502 connected to an end of the first clamping arm 502 away from the first support arm 501. The first clamping arm 502 curls from the end away from the first support arm 501 toward the first support arm 501, with the two first clamping arms 502 positioned between the two first clamping arms 502. The second adapter clamp 2005 further includes a second curling portion connected to an end of the second clamping arm away from the second support arm. The second curling portion curls from the end away from the second support arm toward the second support arm, with the two second clamping arms positioned between the two second curling portions. The second curling portion clamps on both sides of the negative electrode connector 1004.

[0103] By adding two first clamping arms 502 between the two first clamping arms 502 of the first adapter clamp 2002 and two second curling portions between the two second clamping arms of the second adapter clamp 2005, the stability of the connection between the first adapter clamp 2002 and the positive electrode connecting piece 1005 and the second adapter clamp 2005 and the negative electrode connecting piece 1004 is enhanced.

[0104] In some possible implementations, as shown in FIG17 , the first adapter clamp 2002 further includes a first clamping arm 502 connected to an end of the first clamping arm 502 away from the first support arm 501. The two first clamping arms 502 connected to the two first clamping arms 502 are located between the two first clamping arms 502 and curled from the end of the first clamping arm 502 away from the first support arm 501 toward the first support arm 501. The second adapter clamp 2005 further includes a second curling portion connected to an end of the second clamping arm away from the second support arm. The two second curling portions connected to the two second clamping arms are located between the two second clamping arms and curled from the end of the second clamping arm away from the second support arm toward the second support arm.

[0105] By adding two first clamping arms 502 between the two first clamping arms 502 of the first adapter clamp 2002 and two second curling portions between the two second clamping arms of the second adapter clamp 2005, and one of the first clamping arms 502 is curled toward the other first clamping arm 502 (i.e., bent inward), and one of the second curling portions is curled toward the other second curling portion, the problem of the first clamping arm 502 of the first clamping arm 502 and the second curling portion of the second clamping arm being scraped and causing the relevant insulating tape inside the battery cell 10 to rupture and become ineffective due to the presence of sharp ends when they are respectively clamped on the positive electrode connecting piece 1005 and the negative electrode connecting piece 1004 is avoided.

[0106] In one embodiment, as shown in FIG. 20 and FIG. 21 , the first clamping arm 502 is clamped in the first groove 1101 of the positive electrode connecting tab 1005 , and the second curled portion is clamped in the second groove of the negative electrode connecting tab 1004 .

[0107] An embodiment of the present application provides a battery that connects the positive and negative electrodes inside a smart battery cell 10 to a data processing chip, respectively, so that the data processing chip can be powered by the battery cell 10's own computer, effectively solving the problem of unstable power supply caused by wireless power supply, and solving the space occupation problem caused by using a built-in battery for power supply.

[0108] The embodiment of the present application further provides a battery system including the above-mentioned battery. The battery system has all the advantages of the above-mentioned battery, which will not be described in detail here.
