Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1, FIG. 1 is a flowchart of a method for obtaining battery performance information provided by an embodiment of the present invention. As shown in FIG. 1, it includes the following steps:

Step 101. When the terminal device is in a target state, detect a performance parameter of a battery of the terminal device.

Preferably, the target state includes at least one of the following:

The terminal device is in a standby state; the remaining power of the battery is within a preset power range.

With the battery in different states, the equivalent circuit of the battery can change. In this step, the target state can be the state of the terminal device when it is stable, including the remaining power of the battery within a certain range, for example, the power is 10%-20%, or the power is 60%-90%, etc.; or the terminal device is turned off state or standby state, etc., the above-mentioned target state is only a preferred solution.

Wherein, the standby state may be a state in which the terminal device is turned on and does not perform substantive operations. At this time, the load current is usually less than 30mA; the above-mentioned preset power range may be 30%-70%.

When the terminal device is in the above two states at the same time, the battery electrode process is controlled by the charge transfer process (electrochemical reaction), and the impedance caused by the diffusion process can be ignored. Then the equivalent circuit of the battery can be simplified as shown in Figure 2, so the impedance Z of the equivalent circuit is:

Among them, ω is the frequency; j is a complex number, R _Ω is the ohmic impedance, R _ct is the electrochemical reaction impedance, and C _d is the capacitance.

When the terminal device is in any of the above states or in the above two states at the same time, the system stability of the terminal device is better, and the detection performance result is more accurate.

The above-mentioned performance parameters of the battery may include parameters such as electrochemical impedance spectroscopy of the battery, or capacity fading of the battery. Specifically, it can be obtained by simulating the equivalent circuit and devices of the battery according to the source, distribution, influence factor and equivalent circuit of the battery under different states of the electrochemical impedance of the battery, and measuring the ratio of the disturbance signal at different frequencies and the corresponding feedback signal.

Step 102, based on the performance parameter, acquire information indicating the performance of the battery.

In this step, using the performance parameters obtained in step 101, information indicating battery performance can be obtained, so that the performance of the battery can be evaluated. Further, the terminal device may also pre-store the corresponding relationship between the performance parameter and the battery performance, so that the performance information of the battery may be obtained according to the obtained performance parameter.

In the embodiment of the present invention, the above-mentioned method for obtaining battery performance information can be applied to terminal equipment, such as: mobile phone, tablet computer (Tablet Personal Computer), laptop computer (Laptop Computer), personal digital assistant (personal digital assistant, PDA for short) ), Mobile Internet Device (MID) or wearable device (Wearable Device), etc.

According to the battery performance information acquisition method of the embodiment of the present invention, the terminal device can detect the performance parameters of the battery in real time, and acquire the performance information of the battery. The detection method is convenient, and the acquisition efficiency can be improved.

Referring to FIG. 3 , the main difference between this embodiment and the foregoing embodiments is that the performance parameters of the battery include electrochemical impedance spectroscopy, and the terminal device detects the electrochemical impedance spectroscopy of the battery.

Fig. 3 is a flowchart of a method for obtaining battery performance information provided by an embodiment of the present invention, as shown in Fig. 3 , including the following steps:

Step 301. When the terminal device is in a target state, determine an equivalent circuit of a battery of the terminal device.

For an explanation of the target state of the terminal device, reference may be made to relevant descriptions in the foregoing embodiments.

The terminal equipment can determine the equivalent circuit of the battery according to the working state of the battery and the device.

Step 302. Control the waveform generator to input a first electrical signal to the equivalent circuit.

As shown in Figure 4, when a disturbance function X is input to the electrochemical system M, it will output a response signal Y, which is used to describe the functional relationship between the disturbance and the response signal as the transfer function G(ω). If the system is in a stable state under certain conditions, the output signal is a specific function of the disturbance signal. If G(ω) is impedance, it is expressed as Z=Z'+jZ" by complex variable function.

In this step, the terminal device may input the first electrical signal to the equivalent circuit through the waveform generator, and the electrical signal may be a sine wave current or a voltage signal. The above-mentioned waveform generating device may be a programmable DDS (DirectDigital Synthesizer, Direct Digital Synthesizer) waveform generator. For example, the waveform generator in the integrated circuit chip performs a sine wave sweep in the frequency domain from 1Hz to 10KHz, and outputs a sinusoidal potential signal (e=E ₀ Sinωt) with an amplitude of 2mA to the battery equivalent circuit in a steady state.

The terminal device can control the current source device to send the first electrical signal to the CPU (Central Processing Unit, central processing unit), and control the amplifying circuit to send the second electrical signal to the central processing unit. According to different equivalent circuits, CPU's DFT (Design-For-Testability, design for testability) can calculate and fit the real part of Nyquist EIS (Nyquist Electrochemical Impedance Spectrum) impedance according to the input potential signal and current signal and imaginary part, modulus and phase angle.

Specifically, the ratio of the AC potential to the current signal can be measured according to the current and potential signals, that is, the change of the equivalent circuit impedance with the perturbation signal of the sine wave frequency (ω), and the calculation module in the processor can be based on the input potential and current The signal is converted into the relationship between the real part, imaginary part, modulus value and phase angle at different frequencies, and then the NyquistEIS curve is drawn by fitting.

As shown in Figure 5, according to the above method, the ohmic impedance RΩ=24mΩ and the electrochemical reaction impedance Rct1=20mΩ and Rct2=55mΩ of the battery in the terminal equipment in a steady state are calculated, and it can be further judged whether the value of the real part is greater than The preset value, so that an early warning prompt is output when the value is greater than the preset threshold.

Step 305 , based on the electrochemical impedance spectrum, acquire information indicating the performance of the battery.

For the explanation of this step, reference may be made to the description in the foregoing embodiments, and details are not repeated here.

Optionally, the acquiring information indicating the performance of the battery based on the performance parameter includes:

In the case that the performance parameter exceeds the preset parameter range, output warning information for prompting that the battery is at risk.

The terminal device can preset the range of each performance parameter, that is, if the performance parameter is within the above parameter range, it means that the performance of the battery is in a good state, and if it exceeds the preset parameter range, it means that the battery performance is poor , the terminal device outputs risk warning information, including outputting by displaying warning prompts on the screen or outputting voice prompts.

In this way, the terminal device can monitor the performance of the battery in real time, which can improve the detection efficiency of the battery performance.

This implementation manner can also be applied to the embodiment corresponding to FIG. 1 to achieve the same beneficial effect.
