Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] In view of the problems existing in the manual recording method in the existing battery discharge test, the battery discharge monitoring device provided by the embodiment of the present invention uses the control unit to collect the output voltage value of the corresponding sampling path of the battery to be monitored in real time, and when the sampled voltage value is less than the pre-stored When the threshold value is exceeded, the control alarm unit sends out an alarm.

Abstract

The invention belongs to the technical field of battery testing, and provides a battery discharge monitoring device. The device comprises an alarm unit; a detection channel input unit used for providing a discharge voltage sampling channel of the corresponding battery to be monitored, a control unit used for selecting a sampling channel of the detection channel input unit, receiving an output voltage value of the selected sampling channel in real time, and controlling the alarm unit to send an alarm prompt when the output voltage value of the selected sampling channel is smaller than the corresponding threshold value prestored and selected by the control unit. According to the battery discharge monitoring device, compared with the existing manual recording mode, the real-time automatic monitoring of discharge voltage in a battery discharge test can be realized, the waste of human resources is avoided, and the production cost of the product is reduced. In addition, the selection of the sampling channel is realized through the control unit, while the multi-channel monitoring is realized, the sampling channels do not interfere with each other, and the accuracy of a monitoring result is ensured.

Description

technical field [0001] The invention belongs to the technical field of battery testing, and in particular relates to a battery discharge monitoring device. Background technique [0002] In order to ensure the safety of the finished battery, it is necessary to perform a performance test on the battery before leaving the factory, and the battery discharge test is an indispensable test item in the battery performance test. [0003] In the battery discharge test, it is necessary to track the changes of the battery discharge voltage and discharge time in real time. When the voltage during battery discharge reaches the over-discharge voltage, it is necessary to control the battery to stop discharging. During this process, the existing technology records the current discharge voltage value and discharge time of the battery in real time through manual recording. However, since the battery discharge process is relatively long, manual recording is a great waste of human resources, re...
