Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a method and device for identifying new and old batteries. Background Art

[0002] When the battery of an electronic device has been disassembled or replaced, the electronic device may not be able to identify what operations have been performed on the battery. That is, the electronic device cannot identify whether the current battery is a new battery or an old battery, which affects the reasonable loading of battery parameters by the electronic device. For example, when the battery of an electronic device has been disassembled but not replaced, the electronic device may clear the historical cache data of the battery and load the battery parameters according to the new battery. In this way, the new battery parameters will be loaded using an aged battery, which may easily cause problems such as battery power jump, accelerated battery aging, or battery bulging. For another example, after the battery of an electronic device has been replaced, the electronic device may still load the battery parameters according to the historical cache data of the old battery. In this way, the new battery will load the old battery parameters, which may easily cause problems such as inaccurate battery power, low charging voltage, and accelerated battery aging. Therefore, how to identify new and old batteries becomes a problem that needs to be solved. Summary of the invention

[0061] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0062] Electronic device: The electronic device involved in the embodiment of the present invention may be a mobile phone, a tablet computer (pad), a laptop computer, a vehicle terminal, a virtual reality (VR) device, an augmented reality (AR) device, a wireless device in industrial control, a wireless device in self-driving, a wireless device in remote medical surgery, a wireless device in smart grid, a wireless device in transportation safety, a wireless device in smart city, a wireless device in smart home, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a wearable device, a terminal device in a future mobile communication network or a terminal device in a future evolved public mobile land network (PLMN), etc. The embodiment of the present invention does not limit the specific implementation form of the electronic device.

[0063] See also Figure 1 , is a schematic diagram of the structure of an electronic device provided by an embodiment of the present invention. Figure 1 As shown, the electronic device includes a processing chip 101, a battery protection circuit 102 and a battery 103. The processing chip 101 is connected to the battery protection circuit 102, and the battery protection circuit 102 is connected to the battery 103 through a fuse. Optionally, the battery protection circuit 102 includes a first switch, and the processing chip 101 can control the conduction or disconnection of the first switch. For example, the battery protection circuit 102 may include a switch pin of the first switch. The processing chip 101 controls the conduction or disconnection of the first switch by applying different voltage signals to the switch pin of the first switch. In addition, the battery protection circuit 102 is also provided with a connection point for the processing chip 101 to read the voltage, and the processing chip 101 can read the voltage in the battery protection circuit 102 through the corresponding connection point.

[0064] like Figure 1As shown, the battery protection circuit 102 is connected to the battery 103 through a fuse. The fuse may have been blown or may not have been blown. When the fuse has been blown, the battery 103 is disconnected from the battery protection circuit 102. When the fuse is not blown, the battery 103 remains connected to the battery protection circuit 102. That is, when the fuse is in different states, the connection state of the battery 103 and the battery protection circuit 102 is also different. It can be understood that when the battery 103 is used as a power source, when it is connected or disconnected with the battery protection circuit 102, the voltage value at the connection point for reading the voltage in the battery protection circuit 102 is different. It can be understood that when the first switch in the battery protection circuit 102 is disconnected or turned on, the voltage value at the connection point for reading the voltage in the battery protection circuit 102 is different. In the embodiment of the present invention, the processing chip 101 identifies whether the battery 103 is a new battery by running the program stored therein, controlling the conduction or disconnection of the first switch, and reading the voltage value at the relevant connection point in the battery protection circuit 102. It should be noted that the battery protection circuit 102 can be understood as a black box circuit relative to the processing chip 101, and the processing chip 101 does not need to pay attention to the specific circuit structure of the battery protection circuit 102. The specific structure of the battery protection circuit 102 can be designed as needed, and the specific structure of the battery protection circuit 102 does not affect the processing chip 101 to perform the new and old battery identification method of the embodiment of the present invention.

[0065] See also Figure 2 , is a flow chart of a method for identifying new and old batteries provided by an embodiment of the present invention. Figure 2 As shown, the processing steps of the method include:

[0066] 201, the processing chip 101 sends a first signal to the battery protection circuit 102. The first signal is used to control a first switch in the battery protection circuit 102 to be disconnected.

[0067] 202 , the processing chip 101 reads a first voltage in the battery protection circuit 102 .

[0068] 203 , the processing chip 101 determines whether the fuse has blown according to the first voltage.

[0069] Combination Figure 1 , the on or off state of the first switch, the blown or unblown state of the fuse, can make the voltage value of the connection point for reading the voltage value in the battery protection circuit 102 different, and for the convenience of description, the connection point is referred to as the first connection point. Based on this principle, when the processing chip 101 in the embodiment of the present invention controls the first switch to remain in the off state, it reads the voltage of the first connection point as the first voltage. The processing chip 101 can determine whether the fuse has been blown according to the value of the first voltage.

[0070] 204, if it is determined according to the first voltage that the fuse has blown, the processing chip 101 determines that the battery 103 is an old battery. In some embodiments, when the processing chip 101 runs the method of the embodiment of the present invention and has not performed the fuse operation, it is determined in step 203 that the fuse has blown, indicating that the battery 103 has been identified as new and old, and accordingly, the processing chip 101 determines that the battery 103 is an old battery.

[0071] 205. If it is determined according to the first voltage that the fuse is not blown, the processing chip 101 sends a second signal to the battery protection circuit 102 and performs timing. The second signal is used to control the first switch to be turned on. In some embodiments, when the processing chip 101 runs the method of the embodiment of the present invention and has not performed the fuse operation, it is determined in step 203 that the fuse has not been blown, indicating that the battery 103 may be a new battery, and the processing chip 101 sends a second signal to the battery protection circuit 102. The second signal is used to turn on the first switch in the battery protection circuit 102. When the fuse is not blown and the first switch is turned on, the battery protection circuit 102 performs a fuse operation on the fuse. The timing can be understood as the fuse duration of the fuse.

[0072] 206. When the timing duration reaches the first duration, the processing chip 101 sends a third signal to the battery protection circuit 102. The third signal is used to control the first switch to be disconnected. In some embodiments, when the timing duration reaches the first duration, it means that the first switch is turned on for the first duration, that is, the fuse duration of the fuse reaches the first duration, thereby ensuring that the fuse is blown as much as possible. And when the first switch is turned on for the first duration, the first switch is controlled to be disconnected by the third signal.

[0073] 207, the processing chip 101 reads the second voltage in the battery protection circuit 102. In some embodiments, the battery protection circuit 102 may include a second connection point, and the second connection point is used for the processing chip 101 to read the second voltage. Optionally, the second connection point may be a different connection point from the first connection point in the above step. Of course, the second connection point and the first connection point may also be the same connection point.

[0074] 208 , the processing chip 101 determines whether the fuse has blown according to the second voltage.

[0075] 209 , if it is determined according to the second voltage that the fuse has blown, the processing chip 101 determines that the battery 103 is a new battery.

[0076] 210. If it cannot be determined that the fuse has blown according to the second voltage, the processing chip 101 determines that the battery 103 is an illegal battery.

[0077] In some embodiments, after the fuse operation in step 205, if the battery 103 is a new battery, the fuse will change from an unblown state to a blown state when the first switch is turned on. That is, the battery 103 and the battery protection circuit 102 change from being connected to being disconnected. After the battery 103 changes from being connected to being disconnected from the battery protection circuit 102, the voltage of the relevant connection point in the battery protection circuit 102, such as the second connection point mentioned above, will change. That is, the blown state of the fuse can be inferred from the voltage of the relevant connection point in the battery protection circuit 102.

[0078] In an embodiment of the present invention, the processing chip 101 controls the first switch to change from an off state to an on state and the on state is disconnected after a certain period of time. In this process, if the processing chip 101 determines that the fuse has changed from an unblown state to a blown state according to the voltage in the battery protection circuit 102, the processing chip 101 determines that the battery 103 is a new battery. If the processing chip 101 has determined that the fuse is blown when initially controlling the first switch to be disconnected, the processing chip 101 determines that the battery 103 is an old battery. It can be seen that in an embodiment of the present invention, the blown state of the fuse can be judged by the voltage in the battery protection circuit, and then the newness and oldness of the battery 103 in the electronic device can be identified. In some embodiments, for other situations judged according to the read voltage, such as the situation where it cannot be determined that the fuse has been blown according to the second voltage, the processing chip 101 determines the battery 103 as an illegal battery.

[0079] In some embodiments, in step 203, the processing chip 101 determines whether the fuse has been blown according to the first voltage, including: the processing chip 101 determines whether the first voltage is greater than the first threshold. If the first voltage is greater than the first threshold, the processing chip 101 determines that the fuse is not blown. If the first voltage is less than or equal to the first threshold, the processing chip 101 determines that the fuse has been blown. In some embodiments, if the first voltage is less than or equal to the first threshold, the processing chip 101 can read the first voltage N1-1 times again. And determine whether the N1-1 first voltages are all less than or equal to the first threshold. If the N1 first voltages read by the processing chip 101 are all less than or equal to the first threshold, the processing chip 101 determines that the fuse has been blown. In some embodiments, when determining that the fuse has been blown according to the first voltage, the first voltage can be read multiple times, and the fuse can be judged whether it has been blown according to the results of the multiple readings, thereby making the judgment result more accurate.

[0080] In some embodiments, in step 207, the processing chip 101 determines whether the fuse has been blown according to the second voltage, including: the processing chip 101 determines whether the second voltage is greater than the first threshold. If the second voltage is less than or equal to the first threshold, the processing chip 101 determines that the fuse has been blown. If the second voltage is greater than the first threshold, the processing chip 101 cannot determine that the fuse has been blown according to the second voltage. In some embodiments, if the second voltage is greater than the first threshold, the processing chip 101 can read the second voltage N2-1 times again. And determine whether the N2-1 second voltages are all greater than the first threshold. If the N2 second voltages read by the processing chip 101 are all greater than the first threshold, the processing chip 101 cannot determine that the fuse has been blown according to the second voltage. After the fuse operation, if it is not determined that the fuse has been blown, the processing chip 101 determines the battery 103 as an illegal battery. In some embodiments, when it is not determined that the fuse has been blown according to the second voltage, the second voltage can be read multiple times, and the results of the multiple readings can be used to determine whether the fuse has been blown, thereby making the judgment result more accurate.

[0081] See also Figure 3 , is a schematic diagram of the structure of another electronic device provided by an embodiment of the present invention. Figure 3 As shown, the battery protection circuit 102 includes, in addition to the first switch, a first power source and a second switch. Figure 2 Before the method shown determines whether the battery 103 is a new or old battery, the method further includes: sending a fourth signal to the battery protection circuit 102, the fourth signal is used to control the second switch to remain disconnected during the execution of steps 201-210. After the processing chip 101 determines that the battery 103 is a new battery, an old battery or an illegal battery, the method further includes: the processing chip 101 sends a fifth signal to the battery protection circuit 102, the fifth signal is used to control the first switch and the second switch to be turned on, so that the first power supply flows in the battery protection circuit 102. Afterwards, the processing chip 101 reads the third voltage in the battery protection circuit 102, and the processing chip 101 determines the battery parameters of the battery manufacturer based on the third voltage. Optionally, after the processing chip 101 determines the battery parameters of the battery manufacturer, the power supply setting for the battery 103 can be performed based on the battery parameters of the corresponding manufacturer.

[0082] See also Figure 4 , is a flow chart of another method for identifying new and old batteries provided by an embodiment of the present invention. Figure 4 As shown, the processing steps of the method include:

[0083] 300, the processing chip 101 pre-sets a fuse flag bit, and the initial value of the fuse flag bit is a first value. Optionally, the value of the fuse flag bit is a first value or a second value. The first value is used to indicate that the fuse has not been blown. The second value is used to indicate that the fuse has been blown. When the processing chip 101 starts to execute the method of the embodiment of the present invention, the value of the fuse flag bit is the first value.

[0084] 301. The processing chip 101 sends a first switch disconnection signal and a second switch disconnection signal to the battery protection circuit 102. The first switch disconnection signal is used to control the first switch to be disconnected, and the second switch signal is used to control the second switch to be disconnected.

[0085] 302 , the processing chip 101 reads a first voltage in the battery protection circuit 102 .

[0086] 303, the processing chip 101 determines the newness of the battery according to the first voltage and the fuse mark. Specifically, the following situations are included:

[0087] 304 , if the fuse flag bit takes the first value and the first voltage is less than or equal to the first threshold, it is determined that the battery 103 is a used battery.

[0088] 305 , if the value of the fuse flag bit is the first value and the first voltage is greater than the first threshold, execute step 306 .

[0089] 306 , the processing chip 101 sends a first switch-on signal to the battery protection circuit 102 and sets a timing.

[0090] 307 , when the timing duration reaches the first duration, the processing chip 101 sends a first switch disconnection signal to the battery protection circuit 102 and sets the fuse flag bit to the second value, and jumps to step 302 .

[0091] 308 , if the value of the fuse flag bit is the second value and the first voltage is less than or equal to the first threshold, it is determined that the battery 103 is a new battery.

[0092] 309, for situations other than 304, 305 or 308, the battery 103 is determined to be an illegal battery.

[0093] In an embodiment of the present invention, a fuse mark bit is set, and a fuse operation can be performed on the fuse by controlling the first switch. If before the fuse, the first voltage is greater than the first threshold, and after the fuse, the first voltage is less than or equal to the first threshold, it is determined that the battery 103 is a new battery. If before the fuse, the first voltage is less than or equal to the first threshold, it is determined that the battery 103 is an old battery. For other possible situations other than the above situation, the battery 103 is determined to be an illegal battery. For example, when the value of the fuse mark bit is the second value, and the first voltage is greater than the first threshold, the battery 103 is determined to be an illegal battery. That is, the fuse operation of steps 306 and 307 may not cause the fuse to blow, and at this time, the battery 103 is determined to be an illegal battery. At this time, the processing chip 101 can generate a prompt message to prompt the user to go to the after-sales inspection point to inspect the battery 103.

[0094] See also Figure 5 , is a schematic diagram of the structure of another electronic device provided by an embodiment of the present invention. Figure 5 As shown, the electronic device includes a processing chip 101, a battery protection circuit 102 and a battery 103. The battery protection circuit 102 includes a first branch 1021 and a second branch 1022 connected in parallel. Figure 5 As shown, one of the parallel nodes of the first branch 1021 and the second branch 1022 is connected to the battery 103 through a fuse, and the other parallel node is grounded. The first branch 1021 includes a first switch, and the first switch can control the conduction or disconnection of the first branch 1021. The second branch 1022 is used to connect to the battery 103 through a fuse. When the fuse is not blown, the battery 103 can form a power supply loop with the second branch 1022.

[0095] based on Figure 5 The structure shown in the figure, the embodiment of the present invention provides a flowchart of another method for identifying new and old batteries. Figure 6 As shown, the processing steps of the method include:

[0096] 401, the processing chip 101 sends a first signal to the battery protection circuit 102, where the first signal is used to control a first switch in the battery protection circuit 102 to be disconnected. Figure 5 As shown, when the first switch is disconnected, the first branch 1021 is also in a disconnected state. When the fuse is not blown but the first branch 1021 is disconnected, the battery 103 and the first branch 1021 are also in a disconnected state.

[0097] 402 , the processing chip 101 reads a first voltage at a first connection point in the battery protection circuit 102 . Optionally, the first connection point may be a connection point in the second branch 1022 .

[0098] 403, the processing chip 101 determines whether the first voltage is greater than a first threshold. If the first voltage is greater than the first threshold, it means that a power supply loop can be formed between the battery 103 and the second branch 1022, and the processing chip 101 determines that the fuse is not blown, and then executes step 405. If the first voltage is less than or equal to the first threshold, it means that a power supply loop cannot be formed between the battery 103 and the second branch 1022, and the processing chip 101 determines that the fuse is blown, and then executes step 404.

[0099] 404 , the processing chip 101 determines that the battery 103 is a used battery.

[0100] 405, the processing chip 101 sends a second signal to the battery protection circuit 102 and performs timing, and the second signal is used to control the first switch in the battery protection circuit 102 to be turned on. Figure 5 As shown, when it is determined in step 403 that the fuse is not blown, the processing chip 101 sends a second signal to the battery protection circuit 102 to turn on the first switch in the first branch 1021 through the second signal. When the first switch is turned on, the battery 103 forms a power supply circuit with the first branch 1021. In some embodiments, by designing the circuit structure of the first branch 1021 and the second branch 1022, when the first branch 1021 is turned on, the battery 103 can flow into the first branch 1021 preferentially. For example, when the resistance of the first branch 1021 is small, the battery 103 flows into the first branch 1021 and the current flowing through the resistance wire increases, forming a fuse for the resistance wire.
