The size, structural characteristics and applications of a battery pack present a multi-faceted challenge in devising an appropriate leak test. Battery packs are large and often have flexible surfaces. These large internal volumes and expansive surface areas increase variability, which ultimately impacts the accuracy of the selected test method
Key test considerations: • The design of the battery pack can be a key factor in deciding the best leak procedure • Evaluating the best test method should start very early in the design phase of an EV-related product • EV battery packs are susceptible to environmental influences that are difficult to control in the assembly locations
A kind of battery pack air-tightness detection method, comprising: opened the spool of the explosion-proof valve of battery pack using opening device；The explosion-proof valve after opening is connected using detection connector, so that battery pack and detection are in connected state with connector；When being in connected state, air-tightness detection
It can solve the problem that the battery pack cannot be tested for air tightness at any time, so as to reduce the risk of leakage, Reduction of maintenance time and reduction of related costs
The pressure drop method determines the airtightness of the battery pack by measuring the pressure change inside the battery pack. When performing airtightness testing,
The air tightness test is a test method to verify the air tightness of the container, also known as the tightness test or waterproof test. It is a compact test using gas as the pressurizing medium in order to prevent the leakage of the pressure vessel. The air tightness test must be qualified in the hydraulic test before it can be carried out
The air tightness test of the battery pack should be carried out not only during the production process, but also during battery maintenance and inspection. 1-Battery Pack Airtightness Requirements. In actual production, the air tightness of the battery pack must meet the following requirements: Sealing performance, the battery pack shell, interface and
The pressure drop method determines the airtightness of the battery pack by measuring the pressure change inside the battery pack. When performing airtightness testing,
Lithium-ion battery air tightness tests play a crucial role in ensuring long-term performance and durability. Preventing leaks in battery manufacturing through reliable air-tightness testing methods ensures that battery packs perform optimally, safeguarding both performance and safety.
The present invention relates to a method for testing the airtightness of a battery pack having a structure, in which at least one battery module is included in a housing and a high voltage connector for connecting to an external power source is provided on one side of the housing. The method comprises the steps of: a) pressurizing or inhaling air inside a housing through a high

Air tightness testing. For the battery pack that is off the production line or has been repaired, we can''t do a water immersion test on such a battery pack to test the tightness. At this time, we will use the method of detecting air tightness. Test method
Lithium-ion battery air tightness tests play a crucial role in ensuring long-term performance and durability. Preventing leaks in battery manufacturing through reliable air-tightness testing methods ensures that battery packs perform optimally, safeguarding both
Common (and regulatory) functional test requirements for water ingress is per IEC 60529, IPX7 level, which is a destructive test and isn''t applicable for an in-line production testing. This information report offers a method to convert these functional requirements into end-of line nondestructive quality assurance tests of battery packs.
Key test considerations: • The design of the battery pack can be a key factor in deciding the best leak procedure • Evaluating the best test method should start very early in
ELP400 has built-in various test and maintenance modes, which are suitable for the discharging, charging, cycle charging and discharging tests of various lithium batteries on the market. Adopting an intelligent operating system and supports
3.1 Air tightness test The main method for airtightness testing for EVS batteries is to use a gas pressurization system, connect the product to the airtightness tester by using a quick connector, and then charge the gas into the battery box to be tested. After the air pressure stabilizes, observe the change in internal pressure over time.
The front and rear surfaces are flat planes with flanging. Although the design of the slope in the direction increases the difficulty of design and production, it plays a significant role in the sealing effect of the battery pack.
In addition to the above, on the other hand, when a small amount of liquid falls on the sealing slope of the battery pack outside the car when going up, the design of the inclined surface can prevent the liquid from falling on the inclined surface from flowing into the battery pack and prevent the liquid from damaging the battery system.
In order to ensure the tightness of the fixing point between the high/low-voltage connectors and the battery box, the nuts at the fixing point can be blind-hole butt welded nuts, and the flange surface can be directly butt welded to the battery box wall.
Manufacturers must also determine if they are going to test with a positive or negative (vacuum) pressure within the pack. Without question, leak testing an EV battery is one of the most challenging applications that any leak test company will tackle.
The sealing of the EVS battery pack is very critical to the battery pack’s safety in the box. New sealing structures and sealing materials are constantly emerging. Battery pack sealing is constantly being explored, evolved, and improved.
