Problems solved by technology

[0010] The purpose of the present invention is to propose a new low-level safety protection method for battery pack thermal diffusion test in view of the problems that the safety protection part is very safe and prone to deflagration accidents in the cooling and cooling process during the existing battery pack thermal runaway test. This low-level safety protection method for the thermal diffusion test of the battery pack can effectively prevent the safety problems caused by the deflagration of the battery pack during the cooling process after the test is completed.

Embodiment 1

[0033] by attaching Figure 1-4 It can be seen that the present invention relates to a low ground safety protection device for battery pack thermal diffusion test, including a bottom frame 1, a top frame 2, a support column 3 and a sunken pool 4, and the bottom frame 1 and the top frame 2 are supported by a The columns 3 are connected to form a three-dimensional battery pack thermal diffusion test frame 16; the sunken pool 4 is arranged under the battery pack thermal diffusion test frame, and ensures that the battery pack thermal diffusion test frame can sink into the pool as a whole; The outside of the connection between the frame 2 and the support column 3 is provided with a lifting mechanism 5 for lifting the overall frame. The battery pack 6 is placed on the bottom frame 1 during the test. After the test is completed, the lifting mechanism 5 drives the lifting mechanism 5 to lift the battery pack thermal diffusion test frame. , sinking into the sunken pool 4.

Abstract

The invention discloses a low-ground safety protection method of battery pack thermal-diffusion testing. A sinking-type battery pack thermal-runaway testing method is adopted, a battery pack is placedon a stainless-steel structure platform, which is capable of moving up and down, for testing, and in testing, the stainless-steel structure platform is at a highest position, and is exposed out of the ground; and after testing is completed, the stainless-steel structure platform moves down until the battery pack is completely immersed in a sinking water pool, and cooling and temperature reducing,fire and smoke extinguishing and safety isolation on the battery pack are realized. The method can more safely realize cooling and temperature reducing, fire and smoke extinguishing and safety isolation on the battery pack through the one sinking water pool and operation of sinking the battery pack into the water pool after battery pack testing is completed.

Description

technical field [0001] The invention relates to a test method for a power battery, in particular to a low-level safety protection method for a battery pack thermal diffusion test, which can perform a battery pack thermal diffusion test more safely , and the battery pack thermal diffusion test is very stable throughout the operation process; it belongs to the technical field of power battery testing. Background technique [0002] The battery pack market has broad prospects and high research value. Related test verification work is carried out frequently, most of which are destructive tests. Safety accidents such as battery pack leakage, fire, smoke, and explosion may occur during the test process, endangering personal and property safety. In order to reduce the safety risk during the test and isolate the source of danger, it is imperative to take relevant safety measures to ensure the safety of the life and property of the test personnel and equipment. Among them, in order t...
