Example 1
Fig. 1 is a flowchart of a method for determining a data acquisition mode of a battery detection system according to a first embodiment of the present invention, where the method may be performed by a device for determining a data acquisition mode of a battery detection system, and the device for determining a data acquisition mode of a battery detection system may be implemented in hardware and/or software, and the device for determining a data acquisition mode of a battery detection system may be configured in an electronic device such as a computer terminal. As shown in fig. 1, the method includes:
s110, receiving first voltage acquisition data of the battery to be detected, which are acquired through a battery detection system.

In this embodiment, the first voltage acquisition data refers to the voltage of the battery to be measured acquired by the battery detection system. The second voltage acquisition data refer to the voltage of the battery to be detected acquired through the voltage measurement equipment. The battery detection system and the voltage measurement device are different voltage acquisition devices. By way of example, the voltage measurement device may be a high frequency voltage acquisition device such as an oscilloscope or a high frequency data acquisition instrument, which may enable real-time data acquisition at high frequencies, e.g., 10ms, 15ms, 20ms, 30ms, etc. Because the voltage measurement device can realize high-frequency real-time data acquisition, the embodiment takes the second voltage acquisition data of the battery to be measured acquired by the voltage measurement device as standard data to judge the data acquisition mode of the battery detection system. The battery to be measured may be a lithium battery, a lead-acid battery, or the like, and is not limited herein.
Generally, after the battery is discharged, the voltage is rapidly rebounded in a short time under the influence of electrode polarization, and the change speed is in the millisecond level, so that the change of the voltage in the time period can be utilized to detect the data acquisition mode of the battery detection system under the high-frequency condition, and if the acquired data are all real-time acquired data, the voltage change curve is rapidly increased and then becomes stable; if the acquired data are part of the real-time acquired data, the voltage change curve rises successively and then is stable, and the rule of rapid rising is not satisfied. In the application, the first voltage acquisition data and the second voltage acquisition data are data acquired in a preset time period after the discharge of the battery to be tested is finished. The preset time period corresponds to a time period in which the voltage abruptly changes, and specifically, the preset time period may be greater than or equal to a time period in which the voltage abruptly changes, for example, if the time period in which the voltage abruptly changes is 0.2s, the preset time period may be 0.2s, 0.3s, 0.4s, 0.5s, 0.6s, or the like. The first voltage acquisition data are acquired by the battery detection system based on a preset acquisition frequency within a preset time period after the discharge of the battery to be detected is finished.

In this embodiment, the data acquisition mode includes a full real-time data acquisition mode or a partial real-time data acquisition mode. The system comprises a data acquisition system, a data storage system and a data storage system, wherein all real-time data acquisition modes are acquisition modes in which all acquired data are recorded in real time, and the data are relatively real; the partial real-time data acquisition mode is that partial data are acquired in real time, other data are generated by adopting a fitting mode (such as equal interpolation, multiplying power interpolation or other fitting modes, and the like), and the risk of data distortion exists.
Because the voltage measurement device can realize high-frequency real-time data acquisition, the embodiment takes the second voltage acquisition data of the battery to be measured acquired by the voltage measurement device as standard data to judge the data acquisition mode of the battery detection system. Specifically, comparing the first voltage acquisition data of the battery to be tested with the second voltage acquisition data of the battery to be tested, and further determining a data acquisition mode of the battery detection system according to the comparison result; or, the first voltage acquisition data of the battery to be detected and the second voltage acquisition data of the battery to be detected can be differenced, so that the data acquisition mode of the battery detection system is determined according to the voltage difference value, and the data acquisition mode of the battery detection system is not limited.
