Why use SWIR Sensors in Electric Vehicle Battery Production Monitoring & Quality Control Testing?

As the demand for electric vehicles rises, quality control testing for batteries is essential to ensure that battery packs meet the stringent safety, performance, and quality requirements required for the electric vehicle industry. Leak detection is slow and inaccurate at the moment. Even small leaks can reduce battery life, affect performance and increase warranty costs. Even worse, leaking can shortcircuit electrical systems, set fires, or cause damage to battery components.

The non-destructive test of batteries can detect any defects before they leave their production facility. Automated Xray inspection can reveal defects in cells before they leave the factory. This prevents defective cells becoming part of battery modules. The cell structure can also impact quality control methods. Rolled cells can be inspected in 2D. However, stacked cells require 3D computertomography. This is difficult to interpret from a transmissive image.

Engineers use charge and discharge measurements to assess the health of a battery during manufacturing. Engineers also assess the condition of the battery’s battery’s busbar. This is a conductor that is long and isolated from the ground. It is responsible for discharging current throughout the battery pack. Because the weld resistance of batteries is an important indicator, testing the busbar is an essential part of the process. If the weld has any small resistance, this can cause excessive heat and early failures. Engineers can quickly remove defective modules by measuring resistance before a battery becomes operational.

To estimate the battery pack’s useful life, it is important to perform performance testing. The usable life of a battery pack may be drastically reduced by overcharging it or undercharging it. The battery management software (BMS) also uses this information to ensure that the cells operate within safe limits. The BMS must include a charge estimator in order to calculate SoC.

SoC can’t be measured directly, unlike voltage and temperature. It must therefore be calculated using proprietary parameters.

SWIR can be used to adapt the Lithium-Ion Battery Testing Process

High resolution, wide field of view, extended SWIR cameras and high resolution can all be used to solve important inspection issues in lithium-ion batteries. This will allow them to meet increasing quality and performance requirements.

For example, SWIR Vision’s Acuros CQD SWIR sensors can provide imaging through the Li:Ion separator with SWIR wavelengths. These cameras or sensors provide the alignment accuracy required for inter-layer electrodes, resulting in greater energy storage capacity as well as longer battery life.

Because of the ability to see through objects and feed back high-resolution imaging at a rapid-fire rate, these sensors can be adapted as a quality control feature throughout the production process. We expect SWIR cameras to be adopted quickly for battery testing.

What are the significant differences between traditional and minimally invasive spine surgery?

Open spine surgery is still the default choice for most cases of spinal disorders. However, there are some circumstances where minimally invasive spine procedures offer several advantages over traditional open techniques. Minimally invasive spine surgery is now considered the gold standard for treating herniated discs, degenerative disc disease, stenosis, scoliosis, and other common spine conditions.

The main difference between minimally invasive and traditional open spine surgery is its performance. Traditional open spine surgery involves making large incisions along the length of the spine. During this procedure, surgeons must cut through muscle, bone, ligaments, blood vessels, nerves, and organs. In addition, they often use retractors to hold the tissues out of the way while working inside the body. These incisions can cause significant scarring and prolonged healing periods.

Minimally invasive spine surgery, however, uses small incisions and less tissue trauma. First, surgeons work around the spine through tiny incisions, usually no larger than one inch. Then, they insert surgical instruments through those openings rather than cutting into the patient’s skin. This technique prevents extensive tissue damage.

There are many benefits of minimally invasive spine surgery over traditional open spine surgery.

Less Pain

Traditional open spine surgery requires patients to lie completely flat during the entire procedure. They lie flat, which causes extreme discomfort because the muscles surrounding the spine contract and pull against the bones. Patients report feeling intense pressure and pain throughout the entire process.

Minimally invasive spine surgery does not require patients to lie flat during the procedure. Instead, they remain seated upright. This upright position helps reduce the amount of pain caused by the contraction of the muscles. 

As soon as the bricks land in our property our team immediately begin producing them into brick tiles. The pack of bricks will be moved into the manufacturing facility and the team will begin cutting them. We have various state of the art brick trimming machines in our manufacturing plant so can generate a huge quantity of brickslips in a day. On top ofthat, we also have specialised brick cutting tools that permits us to precisly produce corner brick slips, headers and stretcher reveals. We can help Brick Slips

As soon as they are cut, cleaned and packed; the brick tiles are transferred into our picking & packing zone. Our staff will then precisely and meticulously pick your purchase onto a pallet. The minute they have picked the order and they will then check out again look over it to make certain it is unquestionably correct. The boxes of brick tiles are then secured to the pallet. Lastly, they are wrapped and banded to make certain their safety. We then send out our brick slips direct your local distribution centre, ready for dispatch to you!  Latest News

At a different manufacturing facility, we produce our brick specimen panels. The team at this factory will get brick slips that have been trimmed by us. Using a specialised brick slip glue, they fasten the brick tiles to a sample deck. Our samples are completely free of charge to our customers. They are made up of 3 brickslip pieces and 3 brick slip headers to give you a great idea on the true aesthetics of the product.

Ways In Which To Set Up Brick Tiles

Installing your own brick tiles can be quite a fun challenge for you to take on. I am going to talk you through exactly how to do so as per our installation tutorial.

The very first step it sets out as soon as you have collected your equipment, is to prepare your surface area. You do this by initially ensuring that the area you prefer to install your brick tiles is free from dust and debris. A great tool for this is our wire brush which will help you clean up the area rapidly and efficiently. Now you are ready to apply pro primer to the wall. This is created to prime the substrate ready for the applying of your brick slip adhesive. It is advisable to use a large soft paint brush or a roller brush to cover the whole area. Some walls may require a second layer of primer.

Continuing on from this, you’ll really want to lay out your brick tiles on your wall using a spirit level and pen to help you. This will help you to assess how your brickslips will fit on in the corners and edges of your feature wall surface. It is best method to avoid leaving tiny gaps at the top, bottom or either side of your project wall so you may have to cut some of your brick slips to make them fit.
