In order to meet the increasingly higher charging speed requirements of users, various fast charging devices have emerged through continuous improvement of existing technologies. However, existing fast charging devices still have problems such as low charging efficiency and easy overheating. Summary of the Invention

[0004] This application provides an electronic device, including:

[0005] The battery comprises a first charging chip, a second charging chip, and a battery. The first charging chip is a fast charging chip, and the battery includes a negative electrode tab, a first positive electrode tab, and a second positive electrode tab.

[0006] The first charging chip is connected to the first positive electrode and the second positive electrode via a first switching assembly, and the second charging chip is connected to the first positive electrode and the second positive electrode via a second switching assembly.

[0007] When the first switch component is in the first state and the second switch component is in the second state, the first charging chip, the first positive electrode tab, and the negative electrode tab form a first charging path, and the second charging chip, the second positive electrode tab, and the negative electrode tab form a second charging path. The electronic device charges the battery simultaneously through the first charging path and the second charging path.

[0008] When the first switching component is in the third state and the second switching component is in the fourth state, the first charging chip, the second positive electrode, and the negative electrode form a third charging path, and the second charging chip, the first positive electrode, and the negative electrode form a fourth charging path.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0018] The following description, in conjunction with the accompanying drawings, details an electronic device and a charging method provided in this application through specific embodiments and application scenarios.

[0019] Figure 1 This is one of the structural schematic diagrams of an electronic device provided in an embodiment of the present invention, see below. Figure 1 Electronic devices include:

[0020] The battery consists of a first charging chip 100, a second charging chip 200, and a battery 300. The first charging chip 100 is a fast charging chip, and the battery 300 includes a negative electrode tab 330, a first positive electrode tab 310, and a second positive electrode tab 320.

[0021] The first charging chip 100 is connected to the first positive electrode 310 and the second positive electrode 320 through the first switch assembly 400, and the second charging chip 200 is connected to the first positive electrode 310 and the second positive electrode 320 through the second switch assembly 500.

[0022] When the first switch assembly 400 is in the first state and the second switch assembly 500 is in the second state, the first charging chip 100, the first positive electrode 310 and the negative electrode 330 form a first charging path, and the second charging chip 200, the second positive electrode 320 and the negative electrode 330 form a second charging path. The electronic device charges the battery 300 simultaneously through the first charging path and the second charging path.

[0023] When the first switch assembly 400 is in the third state and the second switch assembly 500 is in the fourth state, the first charging chip 100, the second positive electrode 320 and the negative electrode 330 form a third charging path, and the second charging chip 200, the first positive electrode 310 and the negative electrode 330 form a fourth charging path. The electronic device charges the battery 300 simultaneously through the third charging path and the fourth charging path.

[0024] In this embodiment, the first charging chip 100 is a fast charging chip. Fast charging refers to a charging method that can bring the battery 300 to or near full charge within 1 to 2 hours. Compared to the second charging chip 200, the fast charging chip has a higher charging rate for the battery 300, and can charge the battery 300 to a greater extent within the same charging time.

[0025] It should be noted that, such as Figure 2 As shown, Figure 2 This is a structural diagram of battery 300. Figure 2Taking two positive tabs as an example, the battery 300 includes a first positive tab 310, a second positive tab 320, and a negative tab 330. The first terminal of the first charging chip is electrically connected to the negative tab 330, and the second terminal of the first charging chip is electrically connected to both the first positive tab 310 and the second positive tab 320, thus forming a first charging path and a third charging path. Similarly, the first terminal of the second charging chip 200 is electrically connected to the negative tab 330, and the second terminal of the second charging chip 200 is electrically connected to both the first positive tab 310 and the second positive tab 320, thus forming a second charging path and a fourth charging path. The first and third charging paths, along with the second and fourth charging paths, form charging circuits with the battery 300 without interference. Even if one charging path malfunctions, the other charging circuits can still operate normally.

[0026] In this embodiment, the states of the first switch assembly 400 and the second switch assembly 500 are controlled by the first charging chip 100 and the second charging chip 200. The first charging chip 100 and the second charging chip 200 can have built-in programming programs to perform logical control on the first switch assembly 400 and the second switch assembly 500. The first switch assembly 400 includes a first state and a third state, and the second switch assembly 500 includes a second state and a fourth state. The first, second, third, and fourth states refer to the conducting states of the switches. In this embodiment, both the first switch assembly 400 and the second switch assembly 500 can be double-pole double-throw switches or include two switches.

[0027] Specifically, during the first time period, when the first switching component 400 is in the first state and the second switching component 500 is in the second state, the first charging path and the second charging path are connected. At this time, the first positive electrode 310 and the second positive electrode 320 of the electronic device simultaneously obtain power to form simultaneous charging. It should be noted that in this embodiment, the second charging chip 200 is a non-fast charging chip, and the charging efficiency of the second charging chip 200 is lower than that of the first charging chip 100. At this time, due to the difference in charging efficiency between the first charging chip 100 and the second charging chip 200, the amount of power obtained by the first positive electrode 310 and the second positive electrode 320 during the first time period is different, with the amount of power obtained by the first positive electrode 310 being greater than that obtained by the second positive electrode 320. During the second time period, when the first switching component 400 is in the third state and the second switching component 500 is in the fourth state, the third charging path and the fourth charging path are connected. At this time, the first positive electrode 310 and the second positive electrode 320 of the electronic device also simultaneously obtain power, but the amount of power obtained by the first positive electrode 310 is less than that obtained by the second positive electrode 320. Therefore, after the first and second time periods, the first positive electrode tab 310 and the second positive electrode tab 320 receive the same amount of electricity. Compared to the prior art where only one charging circuit charges the battery 300 during the charging period, this application can charge the battery 300 faster. Furthermore, by alternately charging the first positive electrode tab 310 and the second positive electrode tab 320, the current density inside the cell can be made more uniform, thereby reducing polarization resistance and reducing the overall temperature rise of the cell, thus avoiding the problem of the battery 300 easily overheating.

[0028] In this embodiment, during the charging process of battery 300, the first charging chip 100 and the second charging chip 200 form four charging paths with the two positive electrode tabs, respectively. The first switching component 400 and the second switching component 500 control the conduction of these four charging paths to cyclically charge battery 300, ensuring that battery 300 receives the same amount of charge through the multiple electrode tabs. Therefore, compared to the prior art, the electronic device in this application can obtain more power within the same charging time, thereby improving the charging efficiency of battery 300 and reducing the temperature of battery 300 during charging.

[0029] Optionally, the first switch assembly 400 includes a first switch 410 and a second switch 420. The first charging chip 100 is electrically connected to the first positive electrode 310 through the first switch 410, and the first charging chip 100 is electrically connected to the second positive electrode 320 through the second switch 420.

[0030] The second switch assembly 500 includes a third switch 510 and a fourth switch 520. The second charging chip 200 is electrically connected to the second positive electrode 320 through the third switch 510, and the second charging chip 200 is electrically connected to the first positive electrode 310 through the fourth switch 520.

[0031] like Figure 3 As shown, Figure 3 This is the second schematic diagram of the electronic device in this embodiment. In this embodiment, the first switch assembly 400 includes a first switch 410 and a second switch 420, and the second switch assembly 500 includes a third switch 510 and a fourth switch 520. The first charging chip 100 is electrically connected to the first positive electrode 310 and the second positive electrode 320 through the first switch 410 and the second switch 420, respectively. Similarly, the second charging chip 200 is electrically connected to the first positive electrode 310 and the second positive electrode 320 through the third switch 510 and the fourth switch 520, respectively.

[0032] During the charging process of battery 300, when the first switch assembly 400 is in the first state and the second switch assembly 500 is in the second state, the first switch 410 is closed, the second switch 420 is open, the third switch 510 is closed, and the fourth switch 520 is open. This connects the first and second charging paths, while disconnecting the third and fourth charging paths. When the first switch assembly 400 is in the third state and the second switch assembly 500 is in the fourth state, the first switch 410 is open, the second switch 420 is closed, the third switch 510 is open, and the fourth switch 520 is closed. This disconnects the first and second charging paths, while closing the third and fourth charging paths. By incorporating multiple switches into the switch assembly, the opening and closing of each charging path can be better controlled, improving charging efficiency.

[0033] It should be noted that, such as Figure 4 As shown, Figure 4 This is a schematic diagram of the charging cycle in this embodiment. I1 is the output current of the first charging chip 100, I2 is the output current of the second charging chip 200, Ibat1 is the current flowing into the first positive electrode 310, and Ibat2 is the current flowing into the second positive electrode 320. One charging cycle T includes a first sub-cycle t1 and a second sub-cycle t2.

[0034] In this embodiment, during the first sub-cycle t1, the first switch 410 and the third switch 510 are turned on, while the second switch 420 and the fourth switch 520 are turned off. The charging path of the first charging chip 100 is the first switch 410 -> the first positive electrode 310, and the current Ibat1 flowing into the first positive electrode 310 is I1. The charging path of the second charging circuit is the third switch 510 -> the second positive electrode 320, and the current Ibat2 flowing into the second positive electrode 320 is I2. During the second sub-cycle t2, the second switch 420 and the fourth switch 520 are turned on, while the first switch 410 and the third switch 510 are turned off. The charging path of the first charging circuit is the second switch 420 -> the second positive electrode 320, and the current Ibat2 flowing into the second positive electrode 320 is I1. The charging path of the second charging circuit is the fourth switch 520 -> the first positive electrode 310, and the current Ibat1 flowing into the first positive electrode 310 is I2.

[0035] Therefore, after one charging cycle T, both the first charging chip 100 and the second charging chip 200 maintain continuous charging. Although the current magnitudes I1 and I2 are different, during the first sub-cycle t1, the first positive electrode tab 310 and the second positive electrode tab 320 receive currents I1 and I2 respectively, and during the second sub-cycle t2, the first positive electrode tab 310 and the second positive electrode tab 320 receive currents I2 and I1 respectively. In this way, the balance of the current density inside the cell is maintained within one cycle T, and both charging circuits are kept in operation throughout the entire cycle, maximizing the absorption of charging current by the battery 300, thereby improving the charging efficiency of the battery 300.

[0036] Optionally, the first switch assembly 400 and the second switch assembly 500 are respectively a first double-pole double-throw switch and a second double-pole double-throw switch;

[0037] The first double-pole double-throw switch includes a first switch 430 and a second switch 440, and the second double-pole double-throw switch includes a third switch 530 and a fourth switch 540;

[0038] The first charging chip 100 is electrically connected to the first positive electrode 310 through the first switch 430, and the first charging chip 100 is electrically connected to the second positive electrode 320 through the third switch 530.

[0039] The second charging chip 200 is electrically connected to the second positive electrode 320 through the second switch 440, and the second charging chip 200 is electrically connected to the first positive electrode 310 through the fourth switch 540.

[0040] In this embodiment, refer to Figure 5 , Figure 5The third schematic diagram of the electronic device in this embodiment shows that the double-pole double-throw switch is a type of coaxial switch, which includes two switches, and the closed and open states of the two switches are the same.

[0041] During the charging process of battery 300, when the first switch assembly 400 is in the first state and the second switch assembly 500 is in the second state, the first switch 430 is closed, the second switch 440 is closed, the third switch 530 is open, and the fourth switch 540 is open, thereby connecting the first charging path and the second charging path, and disconnecting the third charging path and the fourth charging path.

[0042] When the first switch assembly 400 is in the third state and the second switch assembly 500 is in the fourth state, the first switch 430 is open, the second switch 440 is open, the third switch 530 is closed, and the fourth switch 540 is closed. This disconnects the first and second charging paths, while connecting the third and fourth charging paths. Similar to the above embodiments, in this embodiment, the first positive electrode 310 and the second positive electrode 320 receive the same amount of electricity within one charging cycle. The double-pole double-throw switch simplifies the control logic of the first charging chip 100 and the second charging chip 200, further improving charging efficiency.

[0043] Optionally, the negative electrode tab 330 includes a first negative electrode tab 331 and a second negative electrode tab 332.

[0044] When the first switch assembly 400 is in the first state and the second switch assembly 500 is in the second state, the first charging chip 100 is electrically connected to the first positive electrode 310 and the first negative electrode 331 through the first charging path, and the second charging chip 200 is electrically connected to the second positive electrode 320 and the second negative electrode 332 through the second charging path.

[0045] When the first switch assembly 400 is in the third state and the second switch assembly 500 is in the fourth state, the first charging chip 100 is electrically connected to the second positive electrode 320 and the second negative electrode 332 through the third charging path, and the second charging chip 200 is electrically connected to the first positive electrode 310 and the first negative electrode 331 through the fourth charging path.

[0046] In this embodiment, as Figure 6 As shown, Figure 6As shown in the fourth schematic diagram of the electronic device in this embodiment, the negative electrode tab 330 includes a first negative electrode tab 331 and a second negative electrode tab 332. When the first switch assembly 400 is in the first state and the second switch assembly 500 is in the second state, the first positive electrode tab 310 and the first negative electrode tab 331 form a circuit with the same charging current. Similarly, the second positive electrode tab 320 and the second negative electrode tab 332 form a circuit with the same charging current. When the first switch assembly 400 is in the third state and the second switch assembly 500 is in the fourth state, the second positive electrode tab 320 and the second negative electrode tab 332 form a circuit with the same charging current. Similarly, the first positive electrode tab 310 and the first negative electrode tab 331 form a circuit with the same charging current. Therefore, by additionally setting a negative electrode tab 330, the heat of the battery 300 on the tabs can be effectively distributed during charging, thereby effectively reducing the temperature of the battery 300 during the charging process.

[0047] Optionally, the electronic device further includes a first temperature sensor and a second temperature sensor, wherein the first temperature sensor is electrically connected to the first charging chip 100 and the second temperature sensor is electrically connected to the second charging chip 200.

[0048] The first temperature sensor and the second temperature sensor are used to detect the temperature of the electronic device. When the temperature of the electronic device exceeds a preset threshold, the first charging chip 100 controls the first switching assembly 400 to switch the conduction state of the first charging path and the third charging path, and the second charging chip 200 controls the second switching assembly 500 to switch the conduction state of the second charging path and the fourth charging path.

[0049] In this embodiment, the first temperature sensor is electrically connected to the first charging chip 100, and the first charging chip 100 is used to control the first switch assembly 400 to close or open based on the temperature detection result of the first temperature sensor; the second temperature sensor is electrically connected to the second charging chip 200, and the second charging chip 200 is used to control the second switch assembly 500 to close or open based on the temperature detection result of the second temperature sensor.

[0050] Specifically, the first temperature sensor and the second temperature sensor can respectively detect the first temperature of the first charging chip 100 and the second temperature of the second charging chip 200. When the first temperature or the second temperature exceeds the safe charging temperature of the battery 300, the first temperature sensor or the second temperature sensor will feed back the temperature detection result to the first charging chip 100 and the second charging chip 200. This allows the first charging chip 100 and the second charging chip 200 to control the conduction state of the first switching component 400 or the second switching component 500, preventing the circuit temperature from becoming too high and thus achieving the effect of circuit protection. Furthermore, the charging cycle can be adjusted based on the real-time first and second temperatures, making the charging of the battery 300 safer and more efficient.

[0051] In this embodiment, the first charging chip 100 has a first threshold, and the second charging chip 200 has a second threshold. The first and second thresholds represent preset charging temperatures for the circuit. The battery 300 is generally charged below these preset charging temperatures to ensure circuit safety. Specifically, when both the first and second temperatures are below the first and second thresholds respectively, it indicates that the charging situation is safe, and no adjustment to the charging cycle is needed; the original first charging cycle is retained. However, when the first temperature is greater than or equal to the first threshold and / or the second temperature is greater than or equal to the second threshold, it indicates that a charging malfunction may occur, requiring the first charging cycle to be adjusted to the second charging cycle. This adaptively reduces the circuit temperature, protecting the battery 300. It should be noted that the second charging cycle is shorter than the first charging cycle, and the first and second charging cycles can be adaptively adjusted according to actual conditions.

[0052] Optionally, when the electronic device is in a charging state, the electronic device charges the battery 300 in an alternating manner of a first stage and a second stage;

[0053] In the first stage, the electronic device charges the battery 300 simultaneously through the first charging path and the second charging path; in the second stage, the electronic device charges the battery 300 simultaneously through the third charging path and the fourth charging path.

[0054] In this embodiment, as Figure 4 As shown in the charging cycle diagram, I1 is the output current of the first charging chip 100, I2 is the output current of the second charging chip 200, Ibat1 is the current flowing into the first positive electrode 310, and Ibat2 is the current flowing into the second positive electrode 320. One charging cycle T includes a first stage t1 and a second stage t2.

[0055] In this embodiment, during the first stage t1, the first and third switches are on, while the second and fourth switches are off. The charging path of the first charging chip 100 is the first switch -> the first positive electrode 310, and the current Ibat1 flowing into the first positive electrode 310 is I1. The charging path of the second charging circuit is the third switch -> the second positive electrode 320, and the current Ibat2 flowing into the second positive electrode 320 is I2. During the second stage t2, the second and fourth switches are on, while the first and third switches are off. The charging path of the first charging circuit is the second switch -> the second positive electrode 320, and the current Ibat2 flowing into the second positive electrode 320 is I1. The charging path of the second charging circuit is the fourth switch -> the first positive electrode 310, and the current Ibat1 flowing into the first positive electrode 310 is I2.

[0056] Therefore, after one charging cycle T, both the first charging chip 100 and the second charging chip 200 maintain continuous charging. Although the current magnitudes I1 and I2 are different, during the first stage t1, the first positive electrode tab 310 and the second positive electrode tab 320 receive currents I1 and I2 respectively, and during the second stage t2, the first positive electrode tab 310 and the second positive electrode tab 320 receive currents I2 and I1 respectively. This maintains the balance of the internal current density of the battery cell within one cycle T, and ensures that both charging circuits are operational throughout the entire cycle, maximizing the absorption of charging current by the battery 300 and thus improving the charging efficiency of the battery 300.

[0057] It should be noted that the duration of the first stage t1 is equal to the duration of the second stage t2, and the duration of the first stage t1 and the second stage t2 can be determined according to the heating time of the fast charging tab. For example, when the heating time of the tab is long, the duration of the first stage t1 and the second stage t2 can be shortened accordingly, and when the heating time of the tab is short, the duration of the first stage t1 and the second stage t2 can be increased accordingly.

[0058] In this embodiment, during battery charging, the first charging chip and the second charging chip form four charging paths with the two positive electrode tabs, respectively. The conduction of these four charging paths is controlled by the first and second switching components to cyclically charge the battery, ensuring that the battery receives the same amount of charge through the multiple electrode tabs. Therefore, compared to existing technologies, the electronic device in this application can obtain more power within the same charging time, thereby improving battery charging efficiency and reducing battery temperature during charging.

[0059] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, it should be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved.
