For example, the battery 200 short circuit test apparatus may be formed as an industrial robot, which may automatically perform the battery 200 short circuit test, when integrated.
In the application, the vibration table 110 applies vibration with preset frequency to the battery 200 borne on the vibration table 110, and the vibration and air suction or air inflation can move the foreign matters such as metal particles in the battery 200 under the condition that the foreign matters such as metal particles exist in the battery 200, so that the battery 200 is short-circuited and detected.

The voltage applying device 150 applies a preset voltage to the positive and negative electrodes of the battery 200, and can detect the voltage withstand capability of the battery 200. Thus, the state of the battery 200 under normal use conditions is effectively simulated by means of vibration, pumping and charging and voltage application, so that the reliability of the battery 200 short circuit test is improved. The detecting device 170 is used for acquiring the electrical parameter of the battery 200, so that whether a short circuit exists inside the battery 200 can be conveniently judged through the electrical parameter.
In this embodiment, the battery 200 short circuit test system further includes a controller. The controller is used for controlling the vibration table 110 to apply vibration of a preset frequency to the battery 200 carrying the vibration table 110.

Referring to fig. 1 and 2, the battery short circuit test method includes the following steps:
step S1, controlling the vibration table 110 to apply vibration with preset frequency to the battery 200 bearing the vibration table 110;
step S2, controlling the pumping and inflating device 130 to pump or inflate the interior of the battery 200, and applying a preset pressure to the interior of the battery 200;

The battery 200 short-circuit test method provided in this embodiment simulates the state of the battery 200 under normal use conditions by controlling the vibration table 110 to apply vibration with a preset frequency to the battery 200 carrying the vibration table 110, controlling the pumping and inflating device 130 to pump or inflate the interior of the battery 200, applying preset pressure to the interior of the battery 200 and controlling the voltage applying device 150 to apply preset voltage to the positive and negative poles of the battery 200, thereby improving the reliability of the battery 200 short-circuit test.

In other embodiments of the present application, step S1, step S2 and step S3 may also be performed simultaneously with step S4 in any order.
In this embodiment, step S4 includes the substeps of:
s41, controlling the detection device 170 to acquire the electrical parameters of the battery 200;
s42, judging whether the electrical parameter is within an electrical parameter short-circuit threshold range;
and S43, if the electrical parameter is within the electrical parameter short circuit threshold range, determining that the internal short circuit of the battery 200 has a short circuit.
In this embodiment, steps S41-S43 are performed by the controller. By determining the electrical parameter threshold range to compare with the electrical parameter of the battery, it is possible to conveniently and quickly determine whether a short circuit exists inside the battery 200.
In this embodiment, the electrical parameter is battery leakage current or battery internal resistance.
The detection of the battery leakage current or the battery internal resistance by the detection device 170 can conveniently and intuitively determine whether the battery 200 has a short circuit. For example, when detecting whether there is an internal short circuit in the battery, determining a corresponding electrical parameter short circuit threshold range according to specific parameters of the battery, for example, the battery internal resistance threshold range corresponding to the internal resistance of a normal battery without an internal short circuit is more than 1mΩ, and when detecting that the internal resistance of the battery is 100 Ω, determining that there is a short circuit in the battery. For example, when the threshold value range of the battery leakage current corresponding to the normal battery is within 0.1mA and the detected battery leakage current is 1000mA, the short circuit is determined to exist in the battery side.
In this embodiment, the preset frequency threshold is any value in the range of 0.1Hz to 1000 Hz. The specific preset frequency thereof may be determined according to the specific model and use scenario of the battery 200. The specific preset frequency may be any one of 10Hz, 50Hz, 100Hz, 200Hz, 300Hz, 400Hz, 500Hz, 600Hz, 700Hz, 800Hz, 900Hz and 1000 Hz.
In this embodiment, the preset pressure is any value in the range of-0.9 Mpa to +0.9 Mpa. The specific preset pressure thereof may be determined according to the specific model and use scenario of the battery 200. The specific preset pressure may be any value of-0.9 Mpa, -0.8Mpa, -0.7Mpa, -0.6Mpa, -0.5Mpa, -0.4Mpa, -0.3Mpa, -0.2Mpa, -0.1Mpa, 0Mpa, 0.1Mpa, 0.2Mpa, 0.3Mpa, 0.4Mpa, 0.5Mpa, 0.6Mpa, 0.7Mpa, 0.8Mpa and 0.9 Mpa.
In this embodiment, the preset voltage is any value in the range of 50V to 200V. The specific preset voltage thereof may be determined according to the specific model and use scenario of the battery 200. The specific preset voltage may be any one of 50V, 60V, 70V, 80V, 90V, 100V, 110V, 120V, 130V, 140V, 150V, 160V, 170V, 180V, 190V, and 200V.
In this embodiment, the preset frequency, the preset pressure, and the duration of application of the preset voltage are all any values in the range of 1s to 5 min. The specific duration of application may be determined according to the specific model and use scenario of the battery 200. The specific application duration may be any one of 1s, 10s, 30s, 60s, 90s, 120s, 150s, 180s, 210s, 240s and 300 s.
In this embodiment, step S2 includes the following substeps S21:
when the battery 200 is not filled, the pumping and inflating device 130 is controlled to pump or inflate the battery 200 through the liquid filling port 201 of the battery 200, and a preset pressure is applied to the interior of the battery 200.
The following table reflects the leakage detection rate relationship of the battery 200 under different test conditions:
TABLE 1 relation between leakage detection rate of battery under different test conditions
It can be intuitively seen from the above table that applying the vibration of the preset frequency, the preset voltage, and the preset pressure to the battery 200 increases the detection rate of the battery 200 short-circuit test, thereby increasing the reliability of the battery 200 short-circuit test.
The working principle of the battery short circuit test method and the system provided by the embodiment comprises the following steps:
the vibration table 110 applies vibration with preset frequency to the battery 200 bearing the vibration table 110, and the vibration and air suction or inflation of the condition that foreign matters such as metal particles exist in the battery 200 can enable the foreign matters such as the metal particles to move, so that the battery 200 is short-circuited, and the detection is carried out. The pumping or inflating can also effectively simulate the state of the battery 200 after the cyclic expansion, and two conductors with small spacing can be attached after the expansion of the battery 200, so that the battery is detected by pumping or inflating. The voltage applying device 150 applies a preset voltage to the positive and negative electrodes of the battery 200, and can detect the voltage withstand capability of the battery 200. Thus, the state of the battery 200 under normal use conditions is effectively simulated by means of vibration, pumping and charging and voltage application, so that the reliability of the battery 200 short circuit test is improved. The detecting device 170 is used for acquiring the electrical parameter of the battery 200, so that whether a short circuit exists inside the battery 200 can be conveniently judged through the electrical parameter.
