[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0046] In the field of electronic products, the battery's state of being during the charging process is closely related to the charging function and the protection of charging devices. Therefore, accurately detecting the battery's state of being is particularly important.

[0047] With the advancement of technology, high-power charging is becoming increasingly common to accommodate terminal devices with ever-larger battery capacities. To prevent excessive heat concentration during high-power charging, multiple battery connectors are installed on the battery to disperse the heat source.

[0048] However, how to perform in-situ testing on batteries with multiple battery connectors remains to be solved.

[0049] To address the aforementioned problems, this disclosure proposes a battery comprising a battery body and a connector assembly. The connector assembly includes a master connector, a first slave connector, and a second slave connector. The battery body includes a binary synchronous serial bus, which comprises a first communication line and a second communication line. The battery body communicates with the first slave connector via the first communication line and with the second slave connector via the second communication line. In this disclosure, the connector assembly has two slave connectors. The battery body communicates with the first slave connector via the first communication line of the battery's two-wire synchronous serial bus and with the second slave connector via the second communication line. This achieves battery status detection without adding new electronic components, saving internal space in terminal devices.

[0050] According to an exemplary embodiment, such as Figure 1 and Figure 6 As shown, Figure 1 A schematic diagram of a battery structure is shown. Figure 6 A schematic diagram of the reverse side of the battery is shown. Battery 1 includes a battery body 11 and a connector assembly 12. Wherein, as... Figures 1 to 5As shown, the connector group 12 of battery 1 includes a main connection terminal 123, a first slave connection terminal 121, and a second slave connection terminal 122. The battery body 11 includes a binary synchronous serial bus, which includes a first communication line 13 and a second communication line 14. The battery body 11 is connected to the first slave connection terminal 121 via the first communication line 13 and to the second slave connection terminal 122 via the second communication line 14. Without adding additional electronic components, the electrical connection method of the connector is optimized. The battery connection status can be detected by using the communication status of the binary synchronous serial bus, thereby improving the reliability and safety of the battery connection.

[0051] It should be noted that the battery binary synchronous serial bus in this embodiment is an I2C (Inter-Integrated Circuit) bus, which includes one serial data line SDA and one serial clock line SCL. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 5 Taking the first communication line 13 as the serial data line SDA and the second communication line 14 as the serial clock line SCL as an example, this will be used to explain the present disclosure. This does not constitute a limitation of the present disclosure. In the present disclosure, the first communication line 13 can also be set as the serial clock line SCL and the second communication line 14 can be set as the serial data line SDA.

[0052] like Figures 1 to 5 As shown, the battery body 11 is connected to the first slave connection terminal 121 and the second slave connection terminal 122 of the connector group 12 via two communication lines of the I2C bus. Based on the principle that the I2C bus requires both the serial data line and the serial clock line to be connected simultaneously for communication, the presence status of the battery can be quickly determined by whether the first slave connection terminal 121 and the second slave connection terminal 122 are online at the same time, based on whether the I2C bus is connected.

[0053] Specifically, refer to Figures 1 to 5 The battery body 11 uses the first communication line 13 as the serial data line SDA and the second communication line 14 as the serial clock line SCL. When the battery body 11 needs to communicate with the power-consuming component 211 (refer to...), Figure 7 During communication, simply connect the serial data line SDA of the I2C bus connected to the power-consuming component 211 to the first slave connection terminal 121 of the battery 1, and connect the serial clock line SCL of the power-consuming component 211 to the second slave connection terminal 122 of the battery 1 to achieve communication between the battery body 11 and the power-consuming component 211. It can be understood that when the power-consuming component 211 is the controller of the terminal device, it can realize the presence detection of the battery. The controller, for example, is a core processor (CPU).

[0054] In one exemplary embodiment, such as Figure 1 As shown, battery 1 includes a battery body 11 and a connector assembly 12. The connector assembly 12 includes a main connection terminal 123, a first slave connection terminal 121, and a second slave connection terminal 122. (Refer to...) Figure 2 The first connection terminal 121 includes a first connection portion 1211 and a second connection portion 1212. The first connection portion 1211 includes a first pin SDA_S, and the second connection portion 1212 includes a second pin SDA_S. The first pin SDA_S and the second pin SDA_S are connected, and both pins SDA_S and SDA_S are connected to the first communication line 13. The first connection portion 1211 and the second connection portion 1212 are arranged opposite to each other. For example, one can be located on the upper side and the other on the lower side, arranged vertically opposite each other; or one can be located on the left side and the other on the right side, arranged horizontally opposite each other. In one example, refer to... Figure 2 As shown, the first connecting part 1211 is disposed on the upper side of the first slave connecting end 121, and the second connecting part 1212 is disposed on the lower side of the first slave connecting end 121.

[0055] Among them, such as Figure 2 As shown, the first slave connection terminal 121 includes eight interface pins configured in two groups. One group of interface pins is located in the first connection portion 1211 of the first slave connection terminal 121, and from left to right, they are “-”, “SDA_S”, “NC” and “+”. The other group of interface pins is located in the second connection portion 1212, and from left to right, they are “-”, “SDA_S”, “NC” and “+”. The “SDA_S” interface pin is used to transmit serial data signals, and the “NC” interface pin is left floating to protect the I2C signal.

[0056] Among them, reference Figure 2 By connecting the first pin SDA_S of the first connection portion 1211 and the second pin SDA_S of the second connection portion 1212, it is possible to detect the first slave connection terminal 121 and the first mating slave connection terminal 221 (refer to...). Figure 7(Details will follow) Whether the connection is fully engaged. For example, during the connection process between battery 1 and device body 2, only the upper first connecting part 1211 is engaged (i.e., the upper side of the battery's first connecting part is aligned with the corresponding contact on the terminal device), but the lower second connecting part 1212 is not fully engaged (i.e., the lower side of the battery's second connecting part is not aligned with the corresponding contact on the terminal device). In this case, since the first connecting part 1211 and the second connecting part 1212 are in a connected state, and neither side is fully engaged, the I2C bus will not be connected. This proves that the first slave connecting end 121 of the battery connector is in a disconnected state, i.e., not in position, and battery charging and other operations cannot be performed to ensure the safety and reliability of battery use.

[0057] In this embodiment, as Figure 3 As shown, the second connection terminal 122 includes a third connection portion 1221 and a fourth connection portion 1222. The third connection portion 1221 includes a third pin SCL_S, and the fourth connection portion 1222 includes a fourth pin SCL_S. The third pin SCL_S and the fourth pin SCL_S are connected, and both pins SCL_S and SCL_S are connected to the second communication line 14. The third connection portion 1221 and the fourth connection portion 1222 are arranged opposite to each other. For example, one can be located on the upper side and the other on the lower side, arranged vertically opposite each other; or one can be located on the left side and the other on the right side, arranged horizontally opposite each other. In one example, refer to... Figure 3 As shown, the third connecting part 1221 is disposed on the upper side of the second connecting end 122, and the fourth connecting part 1222 is disposed on the lower side of the second connecting end 122.

[0058] Among them, reference Figure 3 By connecting the first pin SCL_S of the third connection portion 1221 and the second pin SCL_S of the fourth connection portion 1222, it is possible to detect the second slave connection terminal 122 and the second mating slave connection terminal 222 (see reference). Figure 7(Details will follow) Whether the connection is fully engaged. For example, during the connection process between battery 1 and device body 2, only the upper third connection part 1221 is engaged (i.e., the upper side of the battery's third connection part is aligned with the corresponding contact on the terminal device), but the lower fourth connection part 1222 is not fully engaged (i.e., the lower side of the battery's fourth connection part is not aligned with the corresponding contact on the terminal device). In this case, since the third connection part 1221 and the fourth connection part 1222 are in a connected state, and neither side is fully engaged, the I2C bus will not be connected. This proves that the second slave connection end 122 of the battery connector is in a disconnected state, i.e., not in position, and battery charging and other operations cannot be performed to ensure the safety and reliability of battery use.

[0059] Among them, such as Figure 3 As shown, the second slave connection terminal 122 includes eight interface pins configured in two groups. One group of interface pins is located in the third connection portion 1221 of the second slave connection terminal 122, and from left to right, they are “-”, “SCL_S”, “NC” and “+”. The other group of interface pins is located in the fourth connection portion 1222, and from left to right, they are “-”, “SCL_S”, “NC” and “+”. The “SCL_S” interface pin is used to transmit the serial clock signal, and the “NC” interface pin is left floating to protect the I2C signal.

[0060] In one exemplary embodiment, such as Figure 1 As shown, battery 1 includes a battery body 11 and a connector assembly 12. (Referring to...) Figure 1 and Figure 5 The battery body 11 includes a battery cell 111 and a protection board 112 connected to the battery cell 111. The protection board 112 includes a battery fuel gauge 1121. (Refer to...) Figure 1 and Figure 5 The battery 1, which integrates a battery fuel gauge 1121, can communicate via an I2C bus, which includes... Figure 5 The first communication line 13 and the second communication line 14 shown in the figure enable the feedback of information such as battery power and battery status to the controller of the terminal device, so as to realize safe charging through the controller.

[0061] Among them, reference Figure 1 , Figure 2 , Figure 3 and Figure 5The battery power meter 1121 is connected to the first slave connection terminal 121 and the second slave connection terminal 122 of the connector group 12 via two communication lines of the I2C bus, so that when the two communication lines of the controller's I2C bus are connected to the first slave connection terminal 121 and the second slave connection terminal 122 of the connector group 12, the controller can simultaneously detect the engagement status of the first slave connection terminal 121 and the second slave connection terminal 122.

[0062] It should be noted that the controller in this embodiment is the power-consuming component 211 mentioned later (refer to...). Figure 7 One type of controller can detect the presence of the battery. When the battery is not detected, the controller can disconnect the charging path to avoid safety accidents during the charging process.

[0063] When charging the battery of the terminal device, the controller of the terminal device communicates with the battery fuel gauge in the battery to confirm whether the battery is in place. When the controller cannot communicate with the battery fuel gauge, it indicates that the battery is not in place at this time. Then the controller issues an instruction not to charge, thus avoiding charging safety hazards.

[0064] According to an exemplary embodiment, such as Figure 7 As shown in the embodiments of this disclosure, a terminal device is also provided. Figure 7 A schematic diagram of the device body 2 of the terminal device is shown. The terminal device includes the device body 2 and the battery 1 provided in the above embodiments of this disclosure (see reference). Figures 1 to 6 Terminal devices can be electronic devices with large-capacity batteries that enable fast charging, such as smartphones, laptops, and smart wearable devices.

[0065] like Figure 7 As shown, the device body 2 of the terminal device includes a motherboard 21 and a mating connector group 22. The mating connector group 22 includes a mating main connection end 223, a first mating slave connection end 221, and a second mating slave connection end 222. Figure 7 As shown, the mainboard 21 of the device body 2 includes a binary synchronous serial bus, which includes a third communication line 23 and a fourth communication line 24. The mainboard is connected to the first cooperating connection terminal 221 via the third communication line 23, and the mainboard 21 is connected to the second cooperating connection terminal 222 via the fourth communication line 24. In this embodiment, refer to... Figure 7The third communication line 23 is the serial data line SDA of the I2C bus, and the fourth communication line 24 is the serial clock line SCL of the I2C bus. It should be noted that in this embodiment, the first communication line 13 inside the battery is the serial data line SDA of the I2C bus, and the second communication line 14 is the serial clock line SCL of the I2C bus. It should be noted that since the battery ultimately connects to the motherboard 21 through the first communication line 13 and the third communication line 23 to form one communication line, and simultaneously connects to the motherboard 21 through the second communication line 14 and the fourth communication line 24 to form another communication line, to ensure the stability of the communication lines, the first communication line 13 is of the same type as the third communication line 23, and the second communication line 14 is of the same type as the fourth communication line 24. For example, the first communication line 13 and the third communication line 23 are both serial data lines SDA, and the second communication line 14 and the fourth communication line 24 are both serial clock lines SCL.

[0066] When battery 1 is connected in place, the motherboard 21 communicates with the battery body 11 sequentially via the third communication line 23, the first mating slave connection terminal 221, the first slave connection terminal 121, and the first communication line 13, for example, communicating with the battery fuel gauge 1121 of the battery body 11. Similarly, the motherboard 21 communicates with the battery body 11 sequentially via the fourth communication line 24, the second mating slave connection terminal 222, the second slave connection terminal 122, and the second communication line 14, for example, communicating with the battery fuel gauge 1121 of the battery body 11, thus enabling the motherboard 21 of the terminal device to communicate with the battery body 11 via the I2C bus, allowing the terminal device to obtain information such as the battery power and in-place status of battery 1 through the I2C bus. That is, referring to... Figure 1 and Figure 7 The first slave connection terminal 221 of the device body 2 and the first slave connection terminal 121 of the battery 1 form an electrical connection, connecting the terminal device and the battery to form a complete serial data line SDA communication. Simultaneously, the second slave connection terminal 222 of the device body 2 and the second slave connection terminal 122 of the battery form an electrical connection, forming a complete serial clock line SCL communication. With both the serial data line SDA and the serial clock line SCL connected simultaneously, communication between the device body 2 and the battery 1 via the I2C bus is achieved.

[0067] In this embodiment, refer to Figure 1 , Figure 4 and Figure 7When battery 1 is in place, battery 1 and device body 2 transmit serial data signals through the first cooperating connection terminal 221 and the first slave connection terminal 121, and transmit serial clock signals through the second cooperating connection terminal 222 and the second slave connection terminal 122. Since the I2C bus requires both serial data signals and serial clock signals to be connected simultaneously for signal transmission, it can be determined that when the motherboard 21 of device body 2 can communicate with battery body 11, it indicates that the first cooperating connection terminal 221 and the first slave connection terminal 121 are engaged, and the second cooperating connection terminal 222 and the second slave connection terminal 122 are also engaged. When either connection terminal is not engaged, the motherboard 21 cannot communicate with battery body 11. This allows us to determine the engagement status of the first slave connection terminal 121 and the second slave connection terminal 122 of battery 1 with the first cooperating connection terminal 221 and the second cooperating connection terminal 222 of device body 2.

[0068] Among them, reference Figure 1 , Figure 5 and Figure 7 The main connection terminal 223 of the device body 2 can cooperate with the main connection terminal 123 of the battery 1 to form an electrical connection, enabling the battery 1 to supply power to various electrical components on the device body 2, and to charge the battery 1 through the charging interface (not shown) of the device body 2. The main connection terminal 223 of the device body 2 is electrically connected to the electrical components 211 of the device body 2, thereby enabling the electrical components 211 to operate. The electrical components 211 can be, for example, a processor (CPU), a power management chip (PMIC), and a display screen.

[0069] In this embodiment, as Figure 1 and Figure 7 As shown, when battery 1 is installed in the terminal device and the battery is in place, when battery 1 is in a discharging state, that is, when battery 1 supplies power to the device body 2, battery 1 only outputs current to the device body 2 through the main connection terminal 123 and the cooperating main connection terminal 223. It can be determined that when the main connection terminal 123 of battery 1 is not in place, the device body 2 cannot work because it is not powered. This can be used to determine the engagement status of the main connection terminal 123 of battery 1 and the cooperating main connection terminal 223 of device body 2.

[0070] In one exemplary embodiment, such as Figure 1 and Figure 7 As shown, the terminal device includes a device body 2 and a battery 1 provided in the above embodiments of this disclosure. The device body 2 includes a motherboard 21 and a mating connector assembly 22. Referring to... Figure 7The first mating terminal 221 of the connector assembly 22 includes a first mating connection portion 2211 and a second mating connection portion 2212. The first mating connection portion 2211 includes a first mating pin SDA, and the second mating connection portion 2212 includes a second mating pin SDA_S. The first mating pin SDA and the second mating pin SDA_S are disconnected. The first mating pin SDA is connected to the power-consuming components 211 of the motherboard 21 via a third communication line 23, and the second mating pin SDA_S is connected to the second pin SDA_S of the battery 1. The first mating connection portion 2211 and the second mating connection portion 2212 are arranged opposite each other, for example, vertically or horizontally. In one example, refer to... Figure 7 As shown, the first mating connection part 2211 is disposed on the upper side of the first mating connection end 221, and the second mating connection part 2212 is disposed on the lower side of the first mating connection end 221.

[0071] Among them, such as Figure 7 As shown, the first mating connection terminal 221 includes eight interface pins arranged in two groups. One group of interface pins is located in the first mating connection portion 2211 of the first mating connection terminal 221, and from left to right, they are “-”, “SDA”, “NC” and “+”. The other group of interface pins is located in the second mating connection portion 2212, and from left to right, they are “-”, “SDA_S”, “NC” and “+”. The “SDA_S” and “SDA_S” interface pins are used to transmit serial data signals, and the “NC” interface pin is left floating to protect the I2C signal.

[0072] In this configuration, the first connecting portion 1211 of battery 1 is correspondingly disposed with the first mating connecting portion 2211 of device body 2, and the second connecting portion 1212 of battery 1 is correspondingly disposed with the second mating connecting portion 2212 of device body 2. This allows the first connecting portion 1211 of battery 1 to communicate with the first mating connecting portion 2211 of device body 2, and the second connecting portion 1212 of battery 1 to communicate with the second mating connecting portion 2212 of device body 2, thereby enabling communication of the serial data line SDA in the I2C bus. It should be noted that the first connecting end 121 and the first mating connecting end 221 are only fully connected when the first connecting portion 1211 and the first mating connecting portion 2211 are engaged together, and the second connecting portion 1212 and the second mating connecting portion 2212 are also engaged together.

[0073] In this embodiment, the second mating terminal 222 of the mating connector group 22 includes a third mating connection portion 2221 and a fourth mating connection portion 2222. The third mating connection portion 2221 includes a third mating pin SCL, and the fourth mating connection portion 2222 includes a fourth mating pin SCL_S. The third mating pin SCL and the fourth mating pin SCL_S are disconnected. The third mating pin SCL is connected to the power-consuming components 211 of the motherboard 21 through the fourth communication line 24. The fourth mating pin SCL_S is connected to the fourth pin SCL_S of the battery 1.

[0074] Among them, such as Figure 7 As shown, the second mating connection terminal 122 includes eight interface pins arranged in two groups. One group of interface pins is located in the third mating connection portion 2221 of the second mating connection terminal 122, and from left to right, they are “-”, “SCL”, “NC” and “+”. The other group of interface pins is located in the fourth mating connection portion 2222, and from left to right, they are “-”, “SCL_S”, “NC” and “+”. The “SCL” and “SCL_S” interface pins are used to transmit serial clock signals, and the “NC” interface pin is left floating to protect the I2C signal.

[0075] Among them, reference Figures 1 to 7 The third connecting part 1221 of battery 1 is correspondingly provided with the third mating connecting part 2221 of device body 2, and the fourth connecting part 1222 of battery is correspondingly provided with the fourth mating connecting part 2222 of device body 2. This allows the third connecting part 1221 of battery 1 to communicate with the third mating connecting part 2221 of device body 2, and the fourth connecting part 1222 of battery to communicate with the fourth mating connecting part 2222 of device body 2, thereby enabling the connection of the serial clock line SCL in the I2C bus. It should be noted that the second slave connecting end 122 and the second mating slave connecting end 222 are only fully connected when the third connecting part 1221 and the third mating connecting part 2221 are engaged together, and the fourth connecting part 1222 and the fourth mating connecting part 2222 are engaged together.

[0076] In summary, referring to Figure 1 and Figure 7 It can be determined that the battery 1 and the device body 2 can achieve the connection of the serial data line SDA and the serial clock line SCL of the I2C bus through the above method, thereby realizing I2C bus communication, so as to obtain the battery power information, on-site status, etc. through the battery power meter 1121.

[0077] According to an exemplary embodiment, such as Figure 7As shown, the terminal device includes a device body 2 and a battery 1 provided in the above embodiments of this disclosure. The device body 2 includes a motherboard 21 and a mating connector assembly 22. Referring to... Figure 1 and Figure 7 The main connection end 123 of battery 1 and the mating main connection end 223 of device body 2 constitute the main connector. One of the main connection end 123 and the mating main connection end 223 is the male head of the main connector, and the other is the female head of the main connector.

[0078] Reference Figure 1 and Figure 7 The first slave connection end 121 of battery 1 and the first mating slave connection end 221 of device body 2 constitute the first slave connector. One of the first slave connection end 121 and the first mating slave connection end 221 is the male head of the first slave connector, and the other is the female head of the first slave connector.

[0079] Reference Figure 1 and Figure 7 The second slave connection end 122 of battery 1 and the second mating slave connection end 222 of device body 2 constitute a second slave connector. One of the second slave connection end 122 and the second mating slave connection end 222 is the male head of the second slave connector, and the other is the female head of the second slave connector.

[0080] In one example, refer to Figure 1 and Figure 7 The main connection terminal 123, the first slave connection terminal 121, and the second slave connection terminal 122 on the battery 1 side are the female connectors, and the mating main connection terminal 223, the first mating slave connection terminal 221, and the second mating slave connection terminal 222 on the device body 2 side are the male connectors. This does not constitute a limitation of this disclosure. In this disclosure, the main connection terminal, the first slave connection terminal, and the second slave connection terminal on the battery side can also be set as the male connectors, and the mating main connection terminal, the first mating slave connection terminal, and the second mating slave connection terminal on the terminal device side can be set as the female connectors.

[0081] The main connector is primarily used to power the terminal device. The positive and negative terminals of the first and second slave connectors remain disconnected during battery discharge, meaning they do not participate in the power supply process. During battery charging, the positive and negative terminals of the first and second slave connectors become conductive, and all three connectors participate in the charging process. This disperses the heat source during charging across three locations, preventing excessive heat concentration and potential safety hazards.

[0082] According to an exemplary embodiment, such as Figure 8As shown, this disclosure also provides a connector detection method, applied to the terminal device provided in the above embodiments of this disclosure. The execution entity of the method in this embodiment is a control unit on the terminal device, such as a CPU. The detection method in this embodiment includes the following steps:

[0083] Step S101: Obtain the first connection information of the battery through the first communication line and the third communication line;

[0084] Step S102: Obtain the second connection information of the battery through the second communication line and the fourth communication line;

[0085] Step S103: Determine whether the connector is connected or disconnected based on the first connection information and the second connection information.

[0086] In step S101, refer to Figure 1 and Figure 7 The third communication line 23 connects the power-consuming components 211 on the motherboard 21 and the first cooperating slave connection terminal 221. The first communication line 13 connects the battery body 11 and the first slave connection terminal 121. The first cooperating slave connection terminal 221 and the first slave connection terminal 121 cooperate to form an electrical connection, which enables the power-consuming components 211 on the motherboard 21 and the battery body 11 to generate first connection information.

[0087] In step S102, refer to Figure 1 , Figure 5 and Figure 7 The fourth communication line 24 connects the power-consuming components 211 and the second cooperating slave connection terminal 222 of the motherboard 21, and the second communication line 14 connects the battery body 11 and the second slave connection terminal 122. The second cooperating slave connection terminal 222 and the second slave connection terminal 122 cooperate to form an electrical connection, which enables the power-consuming components 211 set on the motherboard 21 and the battery body 11 to generate second connection information.

[0088] In step S103, refer to Figure 1 and Figure 7 The third communication line 23 and the first communication line 13 are both serial data lines (SDA) of the I2C bus, and the fourth communication line 24 and the second communication line 14 are both serial clock lines (SCL) of the I2C bus. If the first connection information is obtained, it indicates that the serial data line SDA is connected; if the second connection information is obtained, it indicates that the serial clock line SCL is connected. Since the I2C bus requires both the serial data line SDA and the serial clock line SCL to be connected simultaneously for communication, it can be determined that if the first and second connection information are obtained, the connector is in a connected state, indicating that the battery is present; if either the first or second connection information is not obtained, the connector is in a disconnected state, indicating that the battery is not present.

[0089] It should be noted that the connector detection in this embodiment actually detects the connection status of the first slave connector (including the mating first slave connection end and the first mating slave connection end) and the second slave connector (including the mating second slave connection end and the second mating slave connection end) mentioned in the previous embodiment. It does not need to detect the connection status of the main connector (including the mating main connection end and the mating main connection segment). Therefore, the main connector is used to power the terminal device; as long as the CPU is running, the main connector is definitely connected. If the main connector is disconnected, power cannot be supplied, and the CPU will stop running. Therefore, as long as the connector status detection process can be performed, it means the main connector is definitely connected and does not need to be detected; only the status of the first and second slave connectors needs to be detected.

[0090] Using the above method, refer to Figure 1 and Figure 7 During battery presence detection, the motherboard 21 and the battery body 11 can complete the presence detection of multiple slave connectors through only one serial data line SDA and a serial clock line SCL. This achieves battery presence detection without adding electronic components, while also reducing the wiring for battery presence detection and saving internal space stacking of terminal equipment.

[0091] In one exemplary embodiment, the detection method further includes:

[0092] The battery is charged when the connector is in the connected state;

[0093] When the connector is disconnected, the battery stops charging.

[0094] In this embodiment, when the method in the above embodiment determines that the connector is in a connected state and the battery is in place, it means that the first slave connector, the second slave connector, and the main connector are all fully engaged. Only then can battery charging begin. When the method in the above embodiment determines that the connector is in a disconnected state and the battery is not in place, it means that the first slave connector is not engaged, or the second slave connector is not engaged, or neither the first nor the second slave connector is engaged, and only the main connector is engaged. In this case, charging cannot proceed. This embodiment controls the start and stop of battery charging by controlling the connection or disconnection status of the connectors, achieving safe charging. When any of the slave connectors is not engaged, battery charging cannot proceed, thus improving the safety of the battery charging process.

[0095] In one exemplary embodiment, the detection method further includes:

[0096] When the battery discharges, the main connector in the connector is electrically connected to the power-consuming components of the terminal device, the positive and negative terminals of the first slave connector in the control connector are disconnected, and the positive and negative terminals of the second slave connector in the control connector are disconnected.

[0097] In this embodiment, as Figure 1 , Figure 4 and Figure 7 As shown, when battery 1 is in place, the positive and negative terminals of the main connection terminal 123 of the connector group 12 of battery 1 are connected to the device body 2, and battery 1 can be discharged and charged through the main connection terminal 123.

[0098] During battery discharge, the positive and negative terminals of the first and second slave connectors are disconnected, allowing the battery to supply power only through the main connector.

[0099] Among them, during battery charging, such as Figure 1 and Figure 7 As shown, the first slave connector and the second slave connector are in a connected state, which allows the battery 1 to distribute the heat points to each connector when charging, thus avoiding the safety hazards caused by the concentration of heat points when charging at high power.
