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.

A typically asked question by property managers, building owners and those accountable for managing fire safety is– can I do my own fire risk evaluation?

In this article, we’re going to discuss why it is feasible– but may not normally be the proper choice to make. Who are we?  Find Out More

The short answer is ‘Of course – you can conduct your own fire risk evaluation’, there is nothing stopping you from Googling an online design template for a fire risk evaluation and filling out the areas to define your property, what you do, and any risks you can identify from the limited expertise you have. If in doubt get in touch  Find Out More

You could possibly even do your own research, perhaps even go to a fire safety program. This may have been reasonable prior to 2005, as the fire service used to visit your property and carry out an audit to provide you with a fire certificate. But, since then, the requirements and law for fire safety became much more rigorous and things changed substantially.

The law for fire safety – The Regulatory Reform (Fire Safety) Order 2005, which was really introduced in 2006– was created to remodel fire safety in England & Wales, to introduce the requirement for a suitable and adequate fire risk evaluation to be carried out for all non-domestic premises.

The words ‘suitable and sufficient’ when used in law, were undoubtedly brought under scrutiny, but the interpretation has since been made very obvious:
A suitable and sufficient fire risk evaluation can only be carried out by a competent person.

‘Competent’ can be defined as someone with enough training, credentials, experience and attitude. A competent person needs to have obtained specific training in relation to fire risk analyses, they must have some form of qualification to back that up, experience in assessing your type of property, and the right approach to ensure they’re able to communicate the results effectively. All of the above can be achieved for your fire risk evaluation by using outside assessors.

Knee Arthritis Treatment How to Get Rid of Knee Arthritis Signs and symptoms

You may be wondering how you can relieve knee pain. There are many effective ways to reduce knee pain and this post will discuss some of the most common methods. These are the quickest ways to alleviate knee pain and get better quickly. Here are three methods to relieve pain. These have been shown to decrease inflammation, swelling, and pain. These aren`t the only solutions. It is also possible to use the treatment of acupuncture to alleviate knee pain.

It is possible that you are unable to tolerate surgery. An alternative treatment that is non-surgical such as knee injections is an option. These injections contain hyaluronic acid which acts as a lubricant for the joint, helping to reduce the friction, pain, and swelling. The injections are generally secure and have less side effects than surgeries. Before you take these procedures, ensure you are aware of the pros and cons.

Acupuncture uses fine needles to stimulate specific parts of the body. Although the procedure is well-known all over the world, there have been few research studies that demonstrate its efficacy. Magnetic pulse therapy is another non-invasive treatment that involves placing the knee within an electric field. This non-invasive treatment is becoming more commonplace and has been shown to work in some instances. Another treatment option for knee pain is stem cell injection. If you`re not looking to undergo surgery, stem cells may be a solution.

The knee joint is prone to osteoarthritis. It can be uncomfortable and can be more painful when the patient places weight on the leg affected. You may also notice swelling and a locking sensation in the knee. If you are experiencing any of these signs you should inform your doctor about it so that they can modify your treatment plan. Once your doctor has determined any specific reason then they`ll recommend the appropriate medicine or procedure. It is possible to get back to living your life without the pain and discomfort of the pain relieving medication.

Another option is cortisone injections to relieve knee pain. Corticosteroids, hyaluronic acid, and platelet rich plasma are some of the medicines employed in this process. Corticosteroid injections may be safe and offer temporary relief. They also allow you to participate in physical therapy and delay your knee replacement surgery. The medication that relieves pain will take several days to take effect and will last between six and twelve weeks.

Gel-One is an treatment choice for knee osteoarthritis that provides a natural supplement to synovial fluid. This easy outpatient procedure can provide relief for upto six months. Before getting injections, patients may apply a topical numbing cream. The doctor will administer the injections to only one knee at a time or both at the same time. A complete treatment program will depend on the type of injection and the particular condition. Before you make any decisions, it is best to consult your doctor.

Besides taking prescription-strength medications, non-steroidal anti-inflammatory drugs are also an effective option. Non-steroidal anti-inflammatory drugs are prescription strength or available over the counter. These treatments can be extremely effective in knee pain relief however they aren`t suggested by medical professionals. You may have surgery carried out if your non-prescription medication isn`t effective.
