Embodiment Construction

[0016] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] The present invention provides a square battery fixture for charge and discharge test aiming at the shortcomings of the existing square battery fixture for charge and discharge test.

[0018] figure 1 As shown, a square battery fixture for charging and discharging tests, the square battery fixture includes an upper splint 1, a lower splint 2, and five bolts 4 connected between the upper splint 1 and the lower splint 2, the upper splint 1 shown Four pole pieces 3 for testing wiring are arranged on both sides to prevent the short circuit of the two poles of the battery. The upper splint 1 and the lower splint 2 are evenly provided with 5 connecting holes for connecting the bolts 4 .

[0019] The connecting holes include several counterbores 5 uniformly arranged on the upper clamping plate 1 and corresponding through holes 6 arranged on t...

Abstract

The invention discloses a square battery fixture used for charging and discharging testing. The square battery fixture comprises an upper clamping plate, a lower clamping plate and a plurality of bolts connected between the upper clamping plate and the lower clamping plate. Pole pieces used for testing wiring are arranged on the two sides of the upper clamping plate, so that a short circuit fault of the two poles of each battery is prevented. The upper clamping plate and the lower clamping plate are uniformly provided with a plurality of connecting holes connected with the bolts. According to the square battery fixture used for charging and discharging testing, the fixture design that the multiple single batteries are in trail is adopted, so that each single battery is large in heat dissipation area and good in heat dissipation effect; the pole pieces used for testing wiring are distributed on the two sides of the upper clamping plate, and thus short wiring of the batteries in the testing process can be avoided; and bolt holes between the adjacent batteries can ensure that the adjacent batteries do not make contact with each other, so that the effects of being simple and effective are achieved.

Description

technical field [0001] The invention relates to a fixture, in particular to a square battery fixture for charging and discharging tests. technical background [0002] Due to the rapid development of electric vehicles, power batteries have been widely used, and the testing process has prominent requirements for heat dissipation and safety. The existing square battery fixture for charging and discharging tests has the problems of poor heat dissipation due to its compact structure, and the positive and negative electrodes are connected on the same side and are easily short-circuited. Contents of the invention [0003] The problem to be solved by the present invention is to provide a square battery fixture with good heat dissipation effect, short-circuit protection and simple structure in view of the shortcomings of the existing square battery fixture for charge and discharge testing. [0004] To achieve the above object, the present invention adopts the following technical s...
