Application of environmental test chamber in lithium battery industry

Lithium ion batteries play a key role in the storage of electric energy With high energy density and light weight, the battery has long been a good choice for Zui in the field of fixed storage renewable energy, as well as automotive or electric vehicle applications The application field is also expanding because of its high storage capacity However, if the operation exceeds the specification, its high energy density and high power density also mean potential danger In addition, it can maintain high power while achieving the longest service life Aging and performance test of battery units and modules of lithium battery in order to determine the service life and power of each battery unit and module under changing conditions, as the leading technical service enterprise of Ling, t Ü V Ü s Ü D will carry out Ji end hardness test on each battery component The battery unit and module of lithium-ion battery used in automobile or consumer field must be tested In the environment simulation box or low temperature incubator produced by binder, the temperature tolerance of battery units and modules will be tested in different temperature ranges and the life analysis will be carried out During the life test, the seasonal aging characteristics of the component cycle and the aging characteristics under the influence of the changing environment will be determined In this case, the value between 70% and 80% of the performance is usually used as the reference value In the life test (standard safety package a), the components will undergo alternating temperature tests without power supply, and the seasonal aging of the cycle will be simulated in this way The equipment is equipped with a second close fitting, independent and adjustable temperature safety device, which can make the detection box at the factory preset temperature of 120 ° C without power supply and prevent it from over heating The controller is limited to 120 ° C, which guarantees this safety measure Temperature alternating test with pulse current to determine the performance of battery unit and module (safety package P), a comprehensive performance test will be carried out For this reason, the components will reach the boundary value of their performance and load capacity under the continuous change of temperature and the alternating action of power on and power off For example, in a low-temperature incubator, the test substance will withstand a constantly changing temperature between - 10 ° C and 55 ° C In the environment simulation box, it can also simulate the detection scene in the climate range of - 30 ° C to 60 ° C, and the relative humidity Zui is 96% The test duration is different If the Ji end of the material is strict, some tests will last for several months For other tests, if the requirement is low, it needs to be calculated in years >Simulate the changing environmental impact, carry out the life test task of battery unit and module, set up the aging and performance test of battery unit and module of lithium-ion battery, maintain the constant environmental conditions in the inspection room, and take special protective measures due to the irreversible reaction danger The non-conductive plug frame is suitable for temperature change test with pulse current Binder solution Binder mkf series environmental simulation box is suitable for high requirements of alternating climate It has steam pressure humidification device and capacitance humidity sensor without deviation, so as to ensure super measurement value Binder KB series low temperature incubator with forced circulation Apt.line climate technology ensures uniform temperature conditions on the whole test object L special coating of inserting frame L heatable overpressure valve L special coating of protection chain and heatable overpressure valve for deflagration: personalized adjustment of environment simulation box and low temperature incubator is essential for the test process, and the test object must be placed on the non-conductive base In view of this, the stainless steel inserts are all coated with special coating and cannot conduct electricity Special casing with rubber plug is installed on the side wall of the equipment to ensure safe and convenient cable threading In addition, special protection measures are needed Due to aging of cells and modules and other electrical characteristics tests, in the case of Zui, the irreversible reaction of battery components may form gas in the detection room Therefore, an additional device shall be installed on the side of the shell to arrange the safety chain so as to prevent the door from being blown open in case of unexpected explosion In order to be able to release gas or build up pressure when necessary, overpressure valve has been installed in the tank These devices can be heated to prevent condensation and possible freezing > the special casing and heating overpressure valve for wiring "is not deeper, but wider, with high equipment reliability For us, the ability to make personalized adjustment is a significant feature of Zui In this way, the environment simulation box can be tailored to our needs " Lisa D ö BLER and Johannes R ö tner, two test engineers working in t Ü v s ü D battery testing GmbH, explained why they decided to use binder equipment When Johannes R ö tner "t Ü v s Ü D battery testing" was conducting the test, the test chamber was always in a state of uncertainty The variable environmental conditions are not always important Binder's climate box is known for its high reliability, "Lisa D ö BLER describes her requirements for testing equipment In addition, the two engineers also commented that the space in the equipment cavity is spacious, not too deep "For us, being able to personalize is a significant feature of Zui In this way, the environment simulation box can be tailored to our needs, "added Johannes R ö diner Zui Environment simulation box mkf advantages Zui high technical reliability convenient and effective space large quantities of equipment "made in Germany" quality application field plastic industry automobile electronics semiconductor industry southeast instrument is Germany binder's Yi agent, the main products are oven, constant temperature and humidity box, environment test box Carbon dioxide incubator, plant growth box, ultra-low temperature refrigerator, low temperature incubator, microbial incubator and other products;
