Abstract

This utility model discloses a clamping device and battery testing system for battery testing. The clamping device includes a clamp body and a conductive rod. The clamp body includes a pivot shaft, an elastic element, and two clamping arms. The clamping arms are rotatably connected via the pivot shaft to form clamping ends and non-clamping ends. The elastic element is disposed between the two clamping arms so that the clamping ends of the two clamping arms can clamp onto the terminals of the battery under test. The conductive rod is movably disposed on the pivot shaft. The conductive rod can move forward relative to the pivot shaft to press against the test area, or can move backward relative to the pivot shaft to separate from the test area. The clamping device adopts a compact pivot structure, and the clamping arms open and close flexibly, making it suitable for operation in confined spaces. At the same time, its non-destructive connection method avoids damage to the battery caused by traditional probe welding, significantly reducing consumable costs. It is especially suitable for scenarios such as batch testing of power battery packs, and has the advantages of high precision, low cost, and long life.
