Description

A car battery box helium detector

technical field

The invention relates to the technical field of helium detectors for battery boxes, in particular to a helium detector for automobile battery boxes.

Background technique

With the development of electric vehicles, the power battery pack, as the core component of pure electric vehicles, directly affects the safety of the whole vehicle. The development of battery pack needs to fully consider many factors, and it is necessary to learn and absorb advanced technology experience at home and abroad, and repeatedly verify and optimize the design scheme. Therefore, the design requirements for the strength, rigidity, heat dissipation, waterproof and insulation of the battery box are very high, so the design and sealing test of the battery box are very important. The use of air tightness leak detectors has strong regularity and can achieve data traceability. Once a product has problems, it can be traced back to the product state or data when it first left the factory. It has the advantages of low subjectivity and no dependence on operators.

The current mainstream battery pack air tightness test, the main test pressure is divided into positive pressure or negative pressure, because the pack itself is thin, the pressure it can withstand is small, so generally it can only accept a few Kpa or dozens of Kpa The current mainstream is to use the differential pressure method to detect the test pressure, and the entire test cycle should be three minutes or five minutes, which will vary according to the size of the product. The test results are generally around 100Pa or 5ml/min. However, in the actual experimental process, once the product volume is large and the area of contacting air surface is large, the pressure difference method appears to have poor stability and repeatability. Although we can use the same product as a comparison piece, due to the large variety of battery pack products, general customers will not choose the test method of adding a comparison piece. Therefore, more and more customers begin to use the positive pressure method (sniffer method) of helium mass spectrometer leak detectors to detect.

Therefore, an automobile battery box helium detector is proposed to solve the above problems.
