Detailed Description

Furthermore, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated, whereby features defined as "first", "second" may explicitly or implicitly include one or more of those features, in the description of the invention "plurality" means two or more unless explicitly defined otherwise.

As shown in fig. 1, a flowchart of steps of a battery detection method according to an embodiment of the present invention is provided, where the method includes the following steps:

step S110: determining whether to perform a fast check

Step S120: the square wave output by a square wave generator is superposed on two electrodes of the battery.

When it is determined that the fast detection is performed after the step S110 is performed, the step S120 is performed.

In step S120, the output square wave is superimposed on the two electrodes of the battery, and the discharging current exceeds half of the rated charging current.

Step S130: and synchronizing the interrupt signals of the input square waves.

In step S130, the square wave output port detects the interrupt signal mainly for synchronizing with the rising edge and the falling edge of the square wave.

Step S140: the voltage waveform of one of the electrodes of the cell is sampled.

In step S140, the sampling frequency is N times of 10 times the square wave frequency, where N is a natural number greater than or equal to 1. And as the sampling frequency is increased, the sampling area obtained by each sampling is closer to the actual shadow area of the square wave. The electrode for specific sampling is the positive electrode.

See also figure 2.

Step S150: obtaining a rising edge shaded area S1 of the voltage waveform and a falling edge shaded area S2 of the voltage waveform for the one electrode of the cell.

The rising edge shaded area S1 of the voltage waveform and the falling edge shaded area S2 of the voltage waveform are the sum of the areas of each sample after a plurality of samples. Where the sampling area is the sampled voltage value multiplied by the sampling time interval.

In actual operation, pulses with a certain specific frequency are given to the anode and the cathode of the battery, the waveform response of the anode of the battery is observed, and how long it takes for the voltage at the two ends of the battery to recover to the rising edge and the falling edge of the square wave is measured. Since the battery itself can be regarded as a huge capacitor, when the rising edge of the square wave comes, it is equivalent to a pulse energy applied to the battery, and then the battery will absorb the energy of the pulse current, and the voltage continuously rises in the absorbing process, and takes the shape of an arc curve, reaches the upper edge of the square wave voltage, and then stabilizes at the upper edge. When the falling edge of the square wave comes, the battery discharges through the square wave generating circuit, the voltage of the battery rapidly drops to form an arc-shaped curve, and the battery reaches the lower edge of the square wave.

The battery life map shown in fig. 2 is measured when the measured value of the remaining capacity (remaining life) of the battery is 100%. The ratio of the shaded area to the square wave area is different. Different patterns are obtained due to different remaining battery capacities. Thus, the life of the battery can be determined according to the ratio of the shaded areas (i.e., S1 and S2) in the different patterns. According to the shadow area ratio difference, sampling 0-100 times for a certain type of battery to obtain the battery life mapping table of the type. When a battery to be measured is randomly given, the terminal equipment can obtain the percentage value of the service life of the battery according to the measured shadow area percentage.

Step S160: the ratio of the rising edge shaded area S1 of the voltage waveform to the rising square wave area is calculated, generating a first ratio.

Step S170: the ratio of the falling edge shaded area S2 of the voltage waveform to the falling square wave area is calculated, generating a second ratio.

In step S160 and step S170, the area of the rising square wave is equal to the square wave amplitude x the width of the rising edge of the square wave. The falling square wave area is the square wave amplitude (i.e., H as shown in fig. 2) x the width of the falling edge of the square wave. When the user obtains the first ratio and the second ratio, the battery life can be roughly judged according to specific data.

Step S180: and comparing the first ratio and the second ratio with a battery life mapping table to obtain the battery life.

This step is an optional step, and in order to let the client know the condition of the battery life more accurately, the obtained first ratio and second ratio can be compared with the battery life mapping table to obtain the specific value of the battery life.

Step S121: and judging whether normal detection is carried out for the first time.

When it is determined that the rapid detection is not performed after the step S110 is performed, it is determined whether the normal detection is performed for the first time.

Step S122: and acquiring battery charging and discharging data stored in the terminal equipment.

And when judging that the normal detection is not carried out for the first time, acquiring the battery charging and discharging data stored in the terminal equipment.

Referring to fig. 3, according to the schematic diagram of the present discharge circuit, the specific method for acquiring the charging and discharging data can take the battery 1 and the internal resistance 2 into consideration, and divide the battery 1 completely without the internal resistance 2 into a battery 1 connected in series with the internal resistance 2 with a small resistance. In this case, if the external load is light (i.e., there are few electronic components connected across the battery), the voltage distributed across the internal resistance 1 is small, whereas if the external load is heavy (i.e., there are many electronic components connected across the battery), the voltage distributed across the internal resistance 1 is relatively large, and a part of the power is consumed at the internal resistance 1 (which may be converted into heat or some complicated reverse electrochemical reaction). The internal resistance 2 of a rechargeable battery 1 when leaving the factory is relatively small, but after long-term use, due to the exhaustion of the electrolyte inside the battery 1 and the reduction of the activity of the chemical substances inside the battery 1, the internal resistance 2 will gradually increase until the internal resistance 2 is so large that the electric quantity inside the battery 1 cannot be normally released, and at this time, the remaining life percentage of the battery 1 is very low. Specifically, the value of the inner group 2 in the battery 1 can be obtained by comparing the fully charged battery 1 with the original capacity of the battery 1.

Step S123: and calculating the service life of the battery according to the acquired battery charging and discharging data.

After each complete charging and discharging period, the charging and discharging data is recorded in the terminal equipment.

The invention has the advantages that the invention supports two methods for judging the service life of the battery, namely, the method adopts the steps of recharging to a full value after complete discharge, and checking the ratio of the sum of the charged electric quantity and the nominal capacity of the battery to judge the quality. This approach is most accurate, but requires a complete charging and a complete discharging process. And secondly, quick electric quantity judgment is supported, and especially when the electric quantity of a new buyer and a purchased mobile phone is in a problem, service suggestions can be provided through quick identification, so that the satisfaction degree of a user can be improved to the maximum extent, and more time is saved for the user.

Specifically, as shown in fig. 4, the terminal device 200 includes a processor 201 and a memory 202. The processor 201 is electrically connected to the memory 202.

In this embodiment, the terminal device 200 is provided with a plurality of memory partitions, the plurality of memory partitions includes a system partition and a target partition, the processor 201 in the terminal device 200 loads instructions corresponding to processes of one or more application programs into the memory 202 according to the following steps, and the processor 201 runs the application programs stored in the memory 202, so as to implement various functions:
