Charging and discharging detection device for lithium battery packs

Abstract

The invention discloses a charging and discharging detection device for lithium battery packs. The charging and discharging detection device comprises a clamping seat, wherein a movable plate is movably arranged in a connecting groove formed in a bottom plate of the clamping seat, and a supporting column is fixed to the center of a driving gear; operating plates are symmetrically arranged on the two sides of the clamping seat, guide rails are fixedly arranged on the operating plates, slide blocks are movably arranged on the guide rails, and charging piles and discharge meters are arranged on the slide blocks on the two sides correspondingly; connecting columns are fixed to the bottom ends of the operating plates, switches I and switches II are arranged on the symmetrical connecting columnscorrespondingly, and rotating rods fixedly penetrate through the centers of driven gears; and the symmetrical driven gears both mesh with the driving gear. According to the charging and discharging detection device for the lithium battery packs, a built-in clamping device can fixedly clamp the lithium battery packs with different specifications, detection is thus facilitated, the charging and discharging detection device can automatically complete charging and discharging detection of the lithium battery packs, the efficiency is high, and the charging and discharging detection device is veryworthy of being promoted.

Problems solved by technology

[0003] However, there are still obvious defects in its use: the above-mentioned device only involves the detection circuit design of battery pack charging and discharging, but does not explain how to realize the positioning and clamping of the battery pack and how to automatically complete the charging and discharging detection of the battery pack. Structural design, the detection process in the above device needs to be manually operated, the efficiency is low, and it is not suitable for mass production and use
