A positive electrode tab 310 is connected to the second positive electrode tab 320;

When the first switch component 400 is in the first state and the second switch component 500 is in the second state, the first charging chip 100 , the first positive electrode tab 310 and the negative electrode tab 330 form A first charging path. The second charging chip 200, the second positive electrode tab 320 and the negative electrode tab 330 form a second charging path.

The charging path simultaneously charges the battery 300 .

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 a fully charged state or close to it within 1 to 2 hours. Compared with the second charging chip 200, the fast charging chip charges the battery 300 at a higher rate, and within the same charging time, the fast charging chip charges the battery 300 with a higher amount of electricity.

It should be noted that, as shown in Figure 2, Figure 2 is a schematic structural diagram of the battery 300. In Figure 2, two positive electrode tabs are taken as an example. The battery 300 includes a first positive electrode tab 310 and a second positive electrode tab 320. Negative electrode tab 330, the first end of the first charging chip is electrically connected to the negative electrode tab 330, and the second end of the first charging chip is electrically connected to the first positive electrode tab 310 and the second positive electrode tab 320 respectively, thus forming a third A charging path and a third charging path. Similarly, the first end of the second charging chip 200 is electrically connected to the negative electrode tab 330, and the second end of the second charging chip 200 is electrically connected to the first positive electrode tab 310 and the second positive electrode tab 320 respectively, thus forming a third The second charging path and the fourth charging path. The first charging path, the third charging path, the second charging path and the fourth charging path form charging circuits with the battery 300 without interfering with each other. When one of the charging paths is in a fault state, the other charging circuits can also be in a normal operating state.

In this embodiment, the states of the first switch component 400 and the second switch component 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 may have built-in programming programs to logically control the first switch component 400 and the second switch component 500 . The first switch component 400 includes a first state and a third state, and the second switch component 500 includes a second state and a fourth state, where the first state, the second state, the third state and the fourth state refer to the conduction of the switch.

When the first switch component 400 is in the third state and the second switch component 500 is in the fourth state during the second time period, the third charging path and the fourth charging path are connected. At this time, the first positive electrode tab 310 of the electronic device and the second positive electrode tab 320 also obtain electricity at the same time. At this time, the electricity obtained by the first positive electrode tab 310 is less than the electricity obtained by the second positive electrode tab 320 . Therefore, after the first time period and the second time period, the first positive electrode tab 310 and the second positive electrode tab 320 are controlled to obtain the same amount of electricity. Compared with the prior art, which only has one charging circuit to charge the battery 300 during the charging time, the present application can charge the battery 300 faster and alternately charge the first positive electrode tab 310 and the second positive electrode tab 320.

The path switch 530 is closed, and the fourth path switch 540 is closed, so that the first charging path and the second charging path are disconnected, and the third charging path and the fourth charging path are connected.

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 the charging condition of the circuit may malfunction at this time, and the first charging cycle needs to be adjusted to the second charging cycle, thereby adaptively reducing the temperature value of the circuit, thereby protecting the battery 300 . It should be noted that the second charging cycle is shorter than the first charging cycle, and the first charging cycle and the second charging cycle Adaptable adjustments can be made according to actual conditions.

The current, IBAT2 is the current flowing into the second positive electrode tab 320. In a charging cycle T, it includes a first stage t ₁ and a second stage t ₂ .

In this embodiment, during the first phase t ₁ , the first switch and the third switch are turned on, and the second switch and the fourth switch are turned off. The charging path of the first charging chip 100 is the first switch -> the first positive electrode tab 310, and the current IBAT1 flowing into the first positive electrode tab 310 is I ₁ . The charging path of the second charging circuit is the third switch -> the second positive tab 320, and the current IBAT2 flowing into the second positive tab is I ₂ .

Therefore, after a charging cycle T, both the first charging chip 100 and the second charging chip 200 maintain charging throughout the entire process. Although the current magnitudes of I ₁ and I ₂ are different, the first positive electrode during the first stage t ₁ The pole tab 310 and the second positive pole tab 320 enter the I ₁ and I ₂ currents respectively. In the second stage t ₂ , the first positive pole tab 310 and the second positive pole tab 320 enter the I ₂ and I ₁ respectively. current. In this way, the balance of the current density inside the battery cell within a period T is maintained, and the two charging circuits are in working state throughout the entire period, maximizing the absorption of charging current by the battery 300, thus improving the charging of the battery 300. efficiency.

It should be noted that the duration of the first phase t ₁ and the duration of the second phase t ₂ are equal, and the duration of the first phase t ₁ and the second phase t ₂ can be based on the time when the fast charging tab is heated. Determine, for example, when the heating time of the tab is long, the duration of the first stage t ₁ and the second stage t ₂ can be adaptively shortened. When the heating time of the tab is short, the first stage t can be adaptively increased. ₁ and the duration of the second phase t ₂ .
