Description

A battery charge and discharge test fixture shared by multiple batteries

technical field

The invention relates to the field of jigs, in particular to a jig for simultaneously charging and discharging multiple batteries.

Background technique

Battery charge and discharge test is a process that must be experienced to understand battery performance. At present, battery charge and discharge tests are usually carried out with the help of battery charge and discharge cabinets. The battery needs to be fixed during the charge and discharge test, otherwise it will cause poor contact of the charge and discharge wires. The battery charge and discharge test cabinet for battery charge and discharge test has multiple channels, and the battery charge and discharge test is also performed on multiple batteries at the same time. However, the current battery charging and discharging test jig usually can only hold one battery. If multiple batteries are charged and discharged at the same time, multiple jigs are required to increase the test cost, and the battery installation is inconvenient and the test process is complicated. For this reason, the researchers designed a multi-battery shared battery charge and discharge test fixture, which can hold multiple batteries at the same time, facilitate installation, reduce test procedures and save test costs.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention designs a battery charging and discharging test fixture shared by multiple batteries to solve the problem of simultaneously discharging and clamping multiple batteries, so as to achieve the effects of convenient installation, reduced test procedures and reduced test costs.

The invention provides a battery charge and discharge test fixture shared by multiple batteries, comprising: a right-angle bottom plate, a press plate assembly on both sides, a middle partition and an upper press plate, the right-angle bottom plate includes a right-angle bottom plate body and a straight slot hole; the two sides The pressing plate assembly includes pressing plate bodies on both sides, grooves and threaded holes, and the pressing plates on both sides are fixed on the right-angle bottom plate by stud bolts; the middle partition is a straight plate with grooves, and the middle partition is installed between the two batteries; The upper pressing plate includes an upper pressing plate body and a straight slot hole, and the upper pressing plate is fixed on the pressing plate bodies on both sides by stud bolts to press the battery and the middle partition.

The right-angled bottom plate is in the shape of a right-angled body with straight slots on the side. The right-angle bottom plate is fixed on the two sides of the pressure plate body by stud bolts.

There are four threaded holes on the two sides of the two-sided pressing plate body, and several groove holes are opened on the front, and the right-angle bottom plate and the upper pressing plate are fixed on the two-sided pressing plate by stud bolts.

There are several grooves on both sides of the middle partition, which are installed between the two batteries.

The upper pressing plate is in the shape of a right angle, with grooves and rounded corners on the side. The right-angled bottom plate, the upper pressing plate and the pressing plates on both sides work together to compress the battery and the separator.

Compared with the prior art, the right-angle bottom plate and the upper platen of the present invention are provided with straight slots, so that the jig can hold different numbers of batteries at the same time, which solves the problem of unified jigs for simultaneous charging and discharging of different numbers of batteries during battery charging and discharging tests.
