Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.

In the related art, when a battery is charged, a cell in the battery is charged through a plurality of charging chips in the battery. Since heat dissipation needs to be considered during charging or discharging. Therefore, when the charging chips are placed, the problem of distributed placement of the charging cells needs to be considered, and then the paths from each charging chip to the cells in the battery are different, so that the electric quantity management is complex, and the unified management is not facilitated. Moreover, since the cell paths from the charging chips to the battery are different, the cost of the battery is too high.

Furthermore, the battery core has a plurality of battery core positive electrode tabs and a plurality of battery core negative electrode tabs, but when charging or discharging, the plurality of battery core positive electrode tabs can only be connected with the charging chip as the battery core positive electrode of the battery core, and the plurality of battery core negative electrode tabs can only be connected with the charging chip as the battery core negative electrode of the battery core, so that the electric quantity flowing into or flowing out of the battery core can not be controlled through the battery core positive electrode tabs and the battery core negative electrode tabs of the battery core.

In view of this, the present disclosure provides a battery. As shown in fig. 1, the battery 100 includes a battery cell 10 and a plurality of switch control circuits 20. Fig. 1 is a schematic diagram illustrating a battery configuration according to an exemplary embodiment. The battery cell 10 includes a plurality of battery cell positive electrode tabs and a plurality of battery cell negative electrode tabs, and the number of the battery cell positive electrode tabs is the same as that of the battery cell negative electrode tabs. And the battery cell positive electrode tabs are respectively connected with at least one of the switch control circuits 20. And the battery cell negative electrode tabs are respectively connected with at least one of the switch control circuits 20. Through a plurality of switch control circuits 20, the communication state between each electric core positive electrode tab and each electric core negative electrode tab can be controlled, and then the number and the passage state of the bipolar ear passages can be determined, so that when the electric core 10 is charged or discharged, the electric quantity flowing into or flowing out of the electric core 10 can be controlled according to at least one bipolar ear passage in the passage state of the electric core 10. The bipolar lug passage is formed by connecting a battery cell positive electrode lug and a battery cell negative electrode lug.

In an embodiment, one or more double tab passages may be included in the battery 100. And at least one battery cell positive electrode lug or at least one battery cell negative electrode lug is included in the same bipolar lug passage. In one example, one cell positive tab and one cell negative tab may be included in the same bipolar tab passage. In another example, one cell positive tab and a plurality of cell negative tabs may be included in the same bipolar tab passage. When connecting a battery core anode tab and a plurality of battery core cathode tabs, can merge a plurality of battery core cathode tabs into a total cathode tab, and then link to each other with battery core anode tab, obtain bipolar ear passageway. In yet another example, multiple cell positive electrode tabs and one cell negative electrode tab may be included in the same bipolar tab passageway. When a plurality of battery cell positive electrode tabs are connected with one battery cell negative electrode tab, the plurality of battery cell positive electrode tabs can be combined into a total positive electrode tab and then connected with the battery cell negative electrode tab to obtain a bipolar tab passage and a bipolar tab passage. In yet another example, multiple cell positive electrode tabs and multiple cell negative electrode tabs may be included in the same bipolar tab passageway. When connecting a plurality of electric core positive pole utmost point ears and a plurality of electric core negative pole utmost point ear, can merge a plurality of electric core positive pole utmost point ears into a total positive pole utmost point ear to merge a plurality of electric core negative pole utmost point ears into a total negative pole utmost point ear, and then be connected total positive pole utmost point ear and total negative pole utmost point ear, obtain the bipolar ear passageway.

Note that in the present disclosure, "double" in the bipolar tab passage refers to tabs of two types including a cell positive tab and a cell negative tab, and does not refer to a number.

In another embodiment, a plurality of battery cell positive electrode tabs may be connected to the same switch control circuit, and further, through the same switch control circuit, whether the plurality of battery cell positive electrode tabs and the plurality of battery cell negative electrode tabs establish a connection relationship may be controlled simultaneously. A plurality of electric core negative pole utmost point ears can link to each other with same on-off control circuit, and then through same on-off control circuit, can control whether a plurality of electric core negative pole utmost point ears establish the relation of connection with a plurality of electric core positive pole utmost point ears simultaneously.

In an implementation scenario, a schematic diagram of a connection structure between each switch control circuit and each cell positive electrode tab and between each switch control circuit and each cell negative electrode tab may be as shown in fig. 1. For convenience of description, 1, 3, 5, 7, 9, 11 are used as a cell positive electrode tab, and 2, 4, 6, 8, 10, 12 are used as a cell negative electrode tab, so as to distinguish the polarities of the tabs. The switch control circuit 21 is connected to 1, 3, and 5 respectively, and is configured to control whether 3 cell positive electrode tabs corresponding to 1, 3, and 5 are connected to other cell negative electrode tabs. The switch control circuit 22 is connected to 2, 4, and 6, respectively, and is configured to control whether 3 cell negative electrode tabs corresponding to 2, 4, and 6 are connected to other cell positive electrode tabs.

When the access state of the double-pole-lug access is controlled through the switch control circuit 21 and the switch control circuit 22, any one or more of 3 battery cell positive pole lugs corresponding to 1, 3 and 5 and a battery cell negative pole lug can be determined through the switch control circuit 21 to establish a battery cell positive pole lug connected with the double-pole-lug access. Any one or more of 3 battery cell negative electrode tabs corresponding to 2, 4 and 6 and a battery cell positive electrode tab establish a double-tab connection path through the switch control circuit 22. For example, when the switch control circuit 21 determines that the cell positive electrode tabs corresponding to the controls 1 and 3 are connected to the cell negative electrode tabs, and when the switch control circuit 22 determines that the cell negative electrode tabs corresponding to the

controls

2 and 4 are connected to the cell positive electrode tabs, the cell positive electrode tabs 1 may be connected to the cell negative electrode tabs 2, and the cell positive electrode tabs 3 may be connected to the cell negative electrode tabs 4, so as to form two pairs of bipolar tab passages. Or the battery cell positive electrode tab 1 and the battery cell positive electrode tab 3 are combined to obtain a total positive electrode tab, the battery cell negative electrode tab 2 and the battery cell negative electrode tab 4 are combined to obtain a total negative electrode tab, and then the total positive electrode tab is connected with the total negative electrode tab to obtain a pair of bipolar tab passages.

In another embodiment, in the same switch control circuit 20, a cell positive electrode tab and a cell negative electrode tab may be connected simultaneously, and when the switch control circuit controls the bipolar tab passage, the connection relationship between the cell positive electrode tab and the cell negative electrode tab connected to the switch control circuit may be directly established, so as to facilitate rapid control of the passage state of the bipolar tab passage. In one embodiment, based on a plurality of cell positive electrode tabs and a plurality of cell negative electrode tabs which are connected with a current switch control circuit, when a bipolar tab passage is established by controlling the plurality of cell positive electrode tabs connected with the current switch control circuit and the plurality of cell negative electrode tabs of the current switch control circuit to be in a passage state, the rest of cell positive electrode tabs can be controlled to be connected with cell negative electrode tabs controlled by other switch control circuits to form the bipolar tab passage; or the residual cell negative pole lugs are controlled to be connected with the cell positive pole lugs controlled by other switch control circuits to form a bipolar lug passage.

In yet another embodiment, the battery 100 further includes: at least one electricity meter. The amount of electrical power flowing into or out of the electrical core 10 can be determined by an electrical meter. When the cell 10 in the battery 100 is charged inward, an amount of electricity flows from the positive electrode of the cell. That is, the electrical quantity flows in from the plurality of cell positive electrode tabs in the at least one bipolar tab passage in the passage state. Therefore, when the placement position of the electricity meter is set, the electricity meter can be respectively connected with the positive electrode lugs of the plurality of battery cells. Or, when the placement positions of the electricity meters are set, the plurality of electricity meters can be connected with the plurality of battery cell positive electrode tabs respectively, that is, each battery cell positive electrode tab is connected with one electricity meter. When the battery cell 10 in the battery 100 discharges outwards, the electricity flows out from the negative electrode of the battery cell. That is, electrical charge flows in from the plurality of cell negative electrode tabs in the at least one bipolar tab passage in the passage state. Therefore, when the placement position of the fuel gauge is set, the fuel gauge can be respectively connected with the plurality of cell negative electrode tabs. Or, when the placement positions of the electricity meters are set, the electricity meters can be connected with the cell negative electrode tabs respectively, that is, each cell negative electrode tab is connected with one electricity meter. In one example, when setting the placement position of the fuel gauge, the fuel gauge may be connected to one cell positive electrode tab 1 and one cell negative electrode tab 2, respectively, that is, the fuel gauge may be connected to one bipolar tab passage. In another example, the same fuel gauge may be connected to multiple bipolar ear passageways.

Based on the same inventive concept, the disclosure also provides a battery control method applied to any one of the batteries.

FIG. 2 is a flow chart illustrating a battery control method according to an exemplary embodiment. As shown in fig. 2, the battery control method includes the following steps S11 to S12.

In step S11, the number of bipolar ear passages is determined based on the operating state of the battery cell.

In the embodiment of the present disclosure, the bipolar tab passage is a passage formed by connecting the cell positive electrode tab and the cell negative electrode tab to each other and is in a connected state. In the battery cell, a plurality of cell positive electrode tabs and a plurality of cell negative electrode tabs may be included, and the number of the cell positive electrode tabs is the same as that of the cell negative electrode tabs. When the bipolar ear passage is in a passage state, external electric quantity can flow into the battery cell cathode from the battery cell anode to charge the battery cell interior. Or the internal electric quantity can flow from the positive electrode of the battery cell to the negative electrode of the battery cell and discharge to the outside of the battery cell. The greater the number of bipolar ear passages in the passage state, the greater the amount of electricity flowing into or out of the cell.

The operation state of the battery cell may include a charge state or a discharge state. Based on the working state of the battery cell, the electric quantity required by charging or discharging the battery cell can be determined, and then the number of the bipolar lug passages is determined, so that when the passage state of the bipolar lug passages is controlled through the switch control circuit, the electric quantity flowing in or out can be controlled, and the electric quantity of the battery cell is reasonably managed. In an example, if the operating state of the battery cell is a charging state, the determined number of the bipolar ear passages may be the maximum number of the bipolar ear passages through which the plurality of battery cell positive electrode tabs and the plurality of battery cell negative electrode tabs included in the battery cell can establish communication, so that it is beneficial to quickly obtain sufficient electric quantity in a short time. In another example, if the operation state of the battery cell is a discharge state, the determined number of bipolar ear passages may be 1, so as to prevent the excessive consumption of the battery.

In step S12, the on-off control circuit controls the state of the paths between the positive electrode tabs of the plurality of battery cells and the negative electrode tabs of the plurality of battery cells, so as to obtain paths of the bipolar tabs with a number that is satisfied.

Through the embodiment, the number of the bipolar ear passages can be determined based on the working state of the battery cell, and then the communication state between the plurality of battery cell positive electrode lugs and the plurality of battery cell negative electrode lugs is controlled through the switch control circuit according to the determined number of the bipolar ear passages, so that the electric quantity flowing into or out of the battery cell can be controlled according to the passage state of the self bipolar ear passages in the process of charging or discharging of the battery cell control circuit, the electric quantity management process is facilitated to be simplified, and the electric quantity is convenient to manage in a centralized manner.

In an embodiment, in order to facilitate flexible control of the amount of electricity flowing into or out of the battery cell, during the charging or discharging process, the number of the bipolar ear passages in the passage state may also be adjusted according to the amount of electricity of the battery cell or the temperature of the battery cell.

FIG. 3 is a flow chart illustrating another battery control method according to an exemplary embodiment. As shown in fig. 3, the battery control method includes the following steps.

In step S21, the number of bipolar ear passages is determined based on the operating state of the battery cell.

In step S22, the switch control circuit controls the state of the paths between the multiple cell positive electrode tabs and the multiple cell negative electrode tabs, so as to obtain a sufficient number of paths for the bipolar tabs.

In step S23, the charge amount of the cell and/or the temperature of the cell is determined.

In the embodiment of the present disclosure, in order to conveniently and reasonably manage the flowing-in or flowing-out electric quantity, the number of the bipolar ear passages may be adjusted according to the electric quantity of the battery cell or the temperature of the battery cell.

According to the electric quantity of the battery core, the current charging condition or the discharging condition of the battery core can be determined, and then whether the number of bipolar ear passages needs to be reduced or increased is determined, so that the current inflow electric quantity can meet the charging requirement, or the outflow electric quantity can meet the discharging requirement.

During the charging or discharging process, the battery cell itself generates heat, which causes the temperature of the battery cell to increase. When the temperature is too high, potential safety hazards, such as explosion, are easily generated, and the use safety of the user is affected. Therefore, when the battery cell is charged or discharged, the current heat dissipation condition of the battery cell can be determined according to the temperature of the battery cell, and then the number of bipolar ear passages is timely reduced, so that the power consumption of the battery cell is reduced, the generation of heat is reduced, and the possibility of potential safety hazards is avoided or reduced.

In an example, for reasonable management and control, and avoid or reduce the possibility of taking place the potential safety hazard, when can confirming electric core electric quantity, also confirm in the lump to the temperature of electric core, and then when guaranteeing that electric core can normally charge or discharge, guarantee user's safety in utilization.

In step S24, the number of the double tab passages is adjusted based on the amount of electricity and/or temperature.

In an embodiment, if the operating state of the battery cell is the charging state, it may be determined whether to adjust the number of bipolar ear passages according to a comparison relationship between the electric quantity of the battery cell and the first electric quantity threshold. The first power threshold can be understood as the power that can maintain the self power requirement without affecting the normal use of the user when the power is not fully charged.

In the charging process, if the electric quantity of the battery cell is smaller than the first electric quantity threshold value, the electric quantity of the battery cell is represented to be insufficient to maintain the self power supply requirement, and the normal use of a user is easily influenced. Therefore, in order to guarantee the charging speed and avoid influencing the use of the user, the determined number of the bipolar ear passages is kept, and the charging is continued by adopting the number of the bipolar ear passages. If the electric quantity of the battery cell is greater than or equal to the first electric quantity threshold value, the electric quantity of the battery cell can maintain the power supply requirement of the battery cell and does not influence the electric quantity normally used by the user. Therefore, in order to avoid excessive battery loss, the number of bipolar lug passages can be reduced, a part of the bipolar lug passages in the passage state is disconnected, and a small number of bipolar lug passages in the passage state are used for charging. In one example, if the number of the bipolar ear passages in the on state is greater than the number of the bipolar ear passages in the off state, when it is determined that the electric quantity of the battery cell is greater than or equal to the first electric quantity threshold value, all the bipolar ear passages in the on state are disconnected, the bipolar ear passages in the off state are restored to the on state, and then the plurality of bipolar ear passages in the restored to the on state are used for charging, so that the number of the bipolar ear passages is reduced, the loss of the battery is equalized, and the service life of the battery is prolonged.

In another embodiment, if the operating state of the battery cell is a discharge state, it may be determined whether to adjust the number of the bipolar ear passages according to a comparison relationship between the electric quantity of the battery cell and the second electric quantity threshold. The first power threshold can be understood as the remaining power that can maintain the self power demand and does not affect the normal use of the user. If the electric quantity of the battery cell is larger than or equal to the second electric quantity threshold value, the electric quantity of the battery cell is represented to be capable of maintaining the power supply requirement of the battery cell and not influencing the normal use of a user, so that the quantity of the bipolar lug passages is kept, and the bipolar lug passages with the quantity are continuously adopted for discharging. If the electric quantity of the battery cell is smaller than the second electric quantity threshold value, the electric quantity of the battery cell is not enough to maintain the self power supply requirement, and the use of the user is possibly influenced. Therefore, in order to avoid excessive battery loss, the number of bipolar lug passages can be reduced, a part of the bipolar lug passages in the passage state is disconnected, and a small number of bipolar lug passages in the passage state are used for discharging. In another example, in order to avoid influencing the power supply requirement of the battery, when the electric quantity of the battery cell is smaller than the second electric quantity threshold, the discharging may be stopped.

In yet another embodiment, when the number of the bipolar ear passages is adjusted based on the temperature, it may be determined whether the number of the bipolar ear passages needs to be reduced according to a corresponding relationship between the temperature of the battery cell and the first temperature threshold. The first temperature threshold may be characterized as a temperature threshold at which the electronic device may have a safety hazard. If the temperature of the battery cell is smaller than the first temperature threshold, it is characterized that the current heat dissipation state of the battery cell is in a normal heat dissipation state, and therefore, the number of bipolar ear passages can be continuously adopted for charging or discharging. If the temperature of the battery core is greater than or equal to the first temperature threshold, it is characterized that the battery is in a state of abnormal temperature, and if the current number of bipolar ear passages are continuously kept for charging or discharging, a risk of potential safety hazard may occur. Therefore, in order to ensure that the battery can be normally used and avoid or reduce the potential safety hazard, the number of the bipolar lug passages can be reduced, part of the bipolar lug passages in the passage state are disconnected, and then a small number of bipolar lug passages in the passage state are adopted for charging or discharging.

In yet another embodiment, when the number of bipolar ear passages is adjusted based on the charge amount and the temperature of the battery cell, the timing for adjusting the number of bipolar ear passages may be determined based on a priority between the charge amount and the temperature. In one example, if the priority of the temperature is greater than the priority of the electric quantity, when the temperature of the battery cell is greater than or equal to the first temperature threshold and the electric quantity of the battery cell does not reach the first electric quantity threshold, the number of bipolar ear passages is reduced. In another example, if the number of open bipolar ear passages is the same as the number of closed bipolar ear passages, when the temperature of the battery cell is greater than or equal to the first temperature threshold and the electric quantity of the battery cell does not reach the first electric quantity threshold, all the closed bipolar ear passages are closed, the closed bipolar ear passages are controlled to be closed through the switch control circuit, and the new closed bipolar ear passages are charged. In another example, if the priority of the electric quantity is greater than the priority of the temperature, when the electric quantity of the battery cell is greater than or equal to the first electric quantity threshold value and the temperature of the battery cell does not reach the first temperature threshold value, the number of bipolar ear passages is reduced.

In another embodiment, if the operation state of the battery cell is a charging state, the number of the dual tab paths may be determined based on the charging power supported between the battery and the power supply device. In one example, the charging power supported between the battery and the power supply device may be determined based on a charging protocol used by the battery and the power supply device when charging. Based on the connection between the battery and the power supply device, it may be determined whether the charging protocol supported between the battery and the power supply device is a battery-specific fast-charge protocol. If the charging protocol supported between the battery and the power supply equipment is a quick charging protocol or a DCP mode included in a BC1.2 protocol, the charging power supported by the battery and the charging equipment is the same when the battery is charged, and further, when the number of the bipolar ear passages is determined, the battery can be charged according to the maximum number of the bipolar ear passages provided by the battery cell, so that the purpose of realizing quick charging is achieved. The DCP mode is adopted to represent that the power supply equipment adopted by the current charging is a charging port special for a battery. In another example, if the charging protocol supported between the battery and the power supply device is a non-fast charging protocol, the number of the bipolar ear paths is determined based on a ratio relationship between the charging power supported by the battery and the charging power supported by the power supply device. The non-rapid charging protocol may include an SDP mode or a CDP mode included in the BC1.2 protocol, where the SDP mode represents that a charger used for current charging is a non-standard charger, and the CDP mode represents that a port used for current charging is a large-current charging port. The number of bipolar ear passages may be determined based on a ratio relationship between the charging power supported by the battery and the charging power supported by the power supply device. For example: the supported charging power of the power supply device is 50 watts (W), the supported charging power of the battery is 100W, and the ratio relationship between the supported charging power of the battery and the supported charging power of the power supply device is 1. According to the total number of the bipolar ear passages of which the electric core is in the passage state, which can be controlled by the switch control circuit, one third of the total number of the bipolar ear passages is controlled to be in the passage state by the switch control circuit, and then the bipolar ear passages are charged by one third of the total number. For example: if the total number of the bipolar ear passages of which the electric core is in the passage state can be controlled to be 9 through the switch control circuit, based on the ratio relationship between the charging power supported by the battery and the charging power supported by the power supply equipment, 3 bipolar ear passages in the passage state are adopted for charging.

In yet another embodiment, the battery further comprises: at least one electricity meter. The total amount of electricity flowing through the dual tab passage can be monitored and determined by an electricity meter. Wherein the total electric quantity comprises the total inflow electric quantity or the total outflow electric quantity. If a fuel gauge is included, the total amount of power flowing through the bipolar ear passage is the amount of power measured by the fuel gauge. If a plurality of electricity meters are included and each bipolar ear passage is provided with an electricity meter, the electricity measured by the electricity meters corresponding to the bipolar ear passages in the passage state is collected, and then the total electricity flowing through the bipolar ear passages is obtained. For example: when the battery core is in a charging state, the bipolar ear passages in the passage state are a bipolar ear passage 1, a bipolar ear passage 2 and a bipolar ear passage 3 respectively. And measuring by using an electricity meter equipped in the double-lug passage 1, and determining that the quantity of electricity flowing through the double-lug passage 1 is a. The amount of electricity flowing through the bipolar tab passage 2 is determined to be b by measurement by an electricity meter equipped with the bipolar tab passage 2. And measuring by using an electricity meter equipped in the double-lug passage 3, and determining that the electric quantity flowing through the double-lug passage 3 is c. The total amount of electricity flowing into the double-tab passage is determined to be t = a + b + c. When the battery core is in a discharging state, the bipolar ear passages in a passage state are a bipolar ear passage 1, a bipolar ear passage 2 and a bipolar ear passage 3 respectively. The electric quantity flowing through the double-lug passage 1 is determined to be a1 through measurement of an electric quantity meter equipped in the double-lug passage 1. The amount of electricity flowing through the bipolar tab passage 2 is determined as b1 by measurement by an electricity meter equipped with the bipolar tab passage 2. And the electric quantity flowing through the double-lug passage 3 is determined to be c1 through measurement of an electric quantity meter arranged in the double-lug passage 3. Determining the total quantity of electricity flowing out of the double-tab passage as t = a1+ b1+ c1.

In one implementation scenario, the battery provided in fig. 1 is taken as an example. Through the switch control circuit 21 and the switch control circuit 22, the positive electrode tab 1 of the battery cell and the negative electrode tab 2 of the battery cell can be controlled to form a pair of bipolar tab passages, and the positive electrode tab 3 of the battery cell and the negative electrode tab 4 of the battery cell can be controlled to form a pair of bipolar tab passages, or the positive electrode tab 5 of the battery cell and the negative electrode tab 6 of the battery cell can be controlled to form a pair of bipolar tab passages. By analogy, the communication states between the battery cell positive electrode lugs 7, 9 and 11 and the battery cell negative electrode lugs 8, 10 and 12 are controlled through other switch control circuits, and the remaining double-lug passages are determined.

When the battery core is in a charging state and a charging protocol supported between the battery and the power supply equipment is a quick charging protocol special for the battery, all the double-lug passages are in a passage state, so that the current flowing into the battery core is the maximum current, and the charging rate is improved. In the charging process, the quantity of the bipolar ear passages in the passage state can be adjusted according to the electric quantity or the temperature of the battery cell, so that the battery cell can be charged normally or discharged, the use safety of a user is ensured, and the electric quantity of the battery cell is reasonably controlled.

In order to facilitate accurate calculation of the electric quantity flowing into or out of each bipolar ear passage, an electricity meter is equipped for each pair of bipolar ear passages, so that the electric quantity flowing through each pair of bipolar ear passages in the passage state is monitored and determined respectively in the process of charging or discharging the battery cell, and finally the total electric quantity flowing into or out of the battery cell is determined.
