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. The battery protection device comprises a shell with an inner containing space, a positioning structure, and a through hole, the positioning structure is arranged at the inner part of the containing space and used for locating the battery from two ends of the battery, an interval space is reserved between the middle part of the battery and a base plate of the shell, and the through hole is arranged on the base plate and communicated with the containing space. According to the battery protection device, the battery is located from two ends by the positioning structure, electrolyte flowing from the inner part of the battery flows outwardly via the through hole arranged on the base plate, in this way, after the explosion of the battery, if there is a little residual electrolyte, even though the shell is not cleaned, the battery erected by the positioning structure is not contacted with the electrolyte when the battery of the next batch is arranged in the shell for the test, and the risk of short circuit of the battery is not increased; when there is less chemicals such as the residual electrolyte in the shell, the cleaning of the shell can be prevented, 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...
