Multi-channel test system and channel identification method thereof

Abstract

The invention discloses a multi-channel test system and a channel identification method thereof, the multi-channel test system comprises a plurality of test devices and a plurality of channel modules, the channel identification method of the multi-channel test system comprises the following steps: presetting a first channel number and a second channel number, storing the first channel number in the channel module, and storing the second channel number in the channel module; storing the second channel number in the test equipment; the channel module obtains a second channel number stored in the corresponding test equipment, compares the first channel number with the second channel number, and outputs alarm prompt information if the first channel number is inconsistent with the second channel number; and the test equipment acquires the first channel number stored in the corresponding channel module, compares the first channel number with the second channel number, and controls the test equipment to stop testing if the first channel number is inconsistent with the second channel number. According to the invention, each tested battery can be bound with corresponding test equipment data one by one, so that data tracing can be carried out during later battery after-sales maintenance.

Description

technical field [0001] The invention relates to the technical field of battery testing, in particular to a multi-channel testing system and a channel identification method thereof. Background technique [0002] With the rapid development of 3C-related products, the sales of various products are also growing rapidly, and the requirements for product safety and stability are becoming more and more strict, so that suppliers need to improve production efficiency while also improving products. security and stability. Some 3C products need corresponding battery power to work, and the battery needs to have various protection controls to ensure that the battery itself will not cause dangerous situations such as spontaneous combustion or abnormal damage and explosion. In this way, it is necessary to perform relevant performance tests on it in all aspects of battery production, thereby generating corresponding data. Under the premise of high efficiency and high output, the performan...

Problems solved by technology

However, the resistor is a passive device, and the resistance value itself has a certain error range (commonly ±1% or ±5%). When the resistance value changes due to temperature changes or aging itself, there will be errors in identification The channel number or the channel number cannot be identified, and when there are many equipment channels, it is easy to cause the resistance values ​​of adjacent channels to be relatively close, and the problem of misjudgment of the resistance value crossing the line is easy to occur, resulting in wrong identification of the channel number and failure to identify each Each tested battery is bound to the corresponding test equipment data one by one, and data cannot be traced back in the later battery after-sales maintenance.
