Battery leakage rapid detection device and detection method thereof

Abstract

The invention relates to a battery leakage rapid detection device and a detection method thereof. The detection device comprises a chassis, a cover body, a gas sensor, a vacuum pump and a display terminal. The chassis is provided with a sealing ring. The chassis is connected with an elevating mechanism. The cover body is arranged above the chassis. When the cover body is engaged with the chassis, a sealed cavity body is formed. The cover body is connected with the vacuum pump through a pipeline. The gas sensor is arranged in the pipeline. A signal wire connected to the gas sensor is connected with a display terminal. The detection method comprises the steps that: a battery to be detected is placed on the chassis, the elevating mechanism controls the chassis to rise until the chassis is closely engaged with the cover body, the vacuum pump carries out vacuum pumping to enable the vacuum degree to reach a set value and maintains the pressure for a period of time, an output value of the gas sensor is reflected on the display terminal, and whether the battery leaks is judged. According to the invention, lithium ion batteries poor in sealing performance can be accurately and effectively detected, the operation is simple, the detection speed is high, the reliability is high, a plurality of batteries can be detected at the same time, the efficiency is improved, and the requirements of large-batch detection are met.

Description

technical field [0001] The invention relates to a detection device for a lithium-ion battery, in particular to a rapid detection device for battery liquid leakage and a detection method thereof. Background technique [0002] Lithium-ion batteries are currently recognized as the best and most promising energy storage components. Compared with lead-acid batteries, nickel-metal hydride batteries, etc., lithium-ion batteries are green batteries with a series of excellent properties, and have been widely used in mobile phones, notebook computers, power tools and new energy vehicles. [0003] The dimensions of cylindrical lithium-ion batteries have been standardized, and the manufacturing process technology is quite mature, so it is undoubtedly the first choice for battery types in the field of electric vehicles. However, due to the large number of single cells required for electric vehicle battery packs and the complex and changeable working environment, the requirements for the...
