Embodiment

[0053] This embodiment provides a battery protection device, such as Figure 2-4 As shown, it includes a housing 1 with an internal accommodation space, installed inside the accommodation space, and is used to position the battery 2 from both ends of the battery 2, so that the middle part of the battery 2 does not contact the bottom plate 110 of the housing 1. 4, and the through hole 3 provided on the bottom plate 110 opposite to the battery 2.

[0054] Specifically, such as Figure 4 As shown, the housing 1 includes a lower housing 11 with an upper opening, and an upper housing 12 mounted on the lower housing 11 through a mounting structure. Wherein, the upper housing 12 includes a top plate 120, and four second side panels 121 connected with the top plate 120 on the same side of the top plate 120; To form four first side panels 111 of the inner accommodation space; when the upper casing 12 is covered on the lower casing 11 through the installation structure, the inner wall...

Abstract

The invention provides a battery protection device, which includes a housing with an internal accommodation space; a positioning structure installed inside the accommodation space for positioning the battery from the front and rear ends of the battery, and making the gap between the middle of the battery and the bottom plate of the housing There is a positioning structure with interval spaces; and a through hole opened on the bottom plate and communicated with the accommodation space. In the battery protection device of the present invention, the positioning structure positions the battery frame from both ends of the battery, and the electrolyte flowing out from the inside of the battery will flow out through the through hole on the bottom plate, so after the battery explodes, if the remaining electrolyte Even if the casing is not cleaned, when the next batch of batteries are placed inside the casing for testing, the batteries erected by the positioning structure will not come into contact with the electrolyte, thus not increasing the risk of short circuit of the battery ; In the battery protection device of the present invention, when the residual electrolyte and other chemical substances inside the housing are small, the housing may not be cleaned, and the cleaning workload is small.

Description

technical field [0001] The invention relates to a battery protection device, and specifically belongs to the technical field of protection devices for charging and discharging tests of lithium batteries. Background technique [0002] In the field of new energy vehicles, lithium batteries are the main power source of vehicles, and their safety has received more and more attention. In order to ensure the safety of the power source of new energy vehicles, it is necessary to perform charge and discharge tests on lithium batteries. When performing charge and discharge tests on lithium batteries, it is generally necessary to connect external charge and discharge equipment to the positive and negative electrodes of the lithium battery, and during the entire test process, the lithium battery is directly exposed to the external environment. Charging, over-discharging, or the operator mistakenly short-circuiting the positive and negative terminals of the battery may cause the lithium...
