Why Introduce SWIR Sensors into Electric Vehicle Battery Production Monitoring and Quality Control Testing?

To ensure that electric vehicle batteries meet the strict safety, performance, or quality requirements, it is crucial to conduct quality control testing on them. Currently, leak detection methods are slow and inaccurate, and even tiny leaks can shorten the battery’s life, impact performance, and increase warranty costs. Even worse, leaking can shortcircuit electrical systems, set fires, or cause damage to battery components.

A battery can be non-destructive tested before it leaves the factory. Automated radiographic inspection (X-ray inspection) can be used to examine hidden inner structures and identify defects before the cells leave the factory. This prevents defective cells becoming part of battery modules. The cell structure is also important for quality control. Rolled cells can be examined in 2D. Stacked cells, however, require 3D computer tomography. This is more difficult than interpreting a transmissive radiograph image.

Engineers assess a battery’s condition during manufacturing by measuring the state of charge or discharge. 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. Any resistance that is too low can lead to excessive heat and early failures. By measuring the resistance before a battery is operational, engineers can remove any defective modules in the shortest time possible.

In addition to performance testing, SoC information is critical to estimate a battery pack’s usable life. It is possible to reduce the usable life of a lithium-ion battery pack by charging it too often or discharging it too frequently. This information is also used by the battery management system (BMS) to maintain the cells within their safe operating limits. BMS must also include a precise charge estimator to calculate SoC.

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

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

In terms of testing equipment suitable for adaptation to existing production systems, high resolution, wide field-of-view, and extended SWIR cameras can be utilized to overcome important lithium-ion battery inspection challenges, therefore enabling lithium and lithium-ion battery producers to meet increasingly demanding performance and quality specifications.

SWIR Vision’s Acuros SWIR cameras, for example, can provide imaging through the Li:Ion separator using SWIR wavelengths. These cameras – or sensors – provide the necessary alignment accuracy of inter-layer electrodes leading directly to more available energy storage capacity and longer battery lifetimes.

These sensors are able to see through objects and provide high-resolution images at a fast-fire rate. This makes them ideal for quality control throughout the manufacturing process. We expect SWIR cameras to be adopted quickly for battery testing.

Preserving independent living, where ever practical, not only boosts feelings of self-esteem, control and dignity, but also eases day-to-day life by decreasing dependence on others. That’s why the importance of encouraging self-reliance in those with movement and strength problems can not be overemphasised. Furthermore, increased independence produces a safer living environment, especially in the elderly, as individuals are less likely to pose a risk to themselves when undertaking daily tasks.By following the below independent living advice and practising the methods detailed, independent living could be attainable to many. To see how we can help -

1. ONLY COUNT ON HELP WHERE NECESSARY

 As a carer, the trick to fostering successful independent living is by administering care only when it’s genuinely needed, as this will encourage self-reliance where the patient is able.Look at the below list, and decide which areas your patient definitely needs help with, and which they could actually take care of themselves;- Preparing meals and shopping for meals- Cleaning, and other standard household tasks- Organising bills and finances- Driving- Personal grooming, and washingAltering care to only be provided where necessary is a key independent living aid, and will have a knock-on effect concerning the amount of visits the patient receives from those providing support, who will be providing help (family, care staff or physicians), and where assistance will be based (in-home, hospital or care-facility based).

2. IF FEASIBLE, MANAGE OWN MEDICATION AND APPOINTMENTS

 Whilst this independent living aid would not be advisory for all people (such as those fighting dementia), if your sufferer is able to manage their own prescribed medications and consultations, this can massively increase their independence, and offer a feeling of control. This process can be made easier by setting phone reminder alerts both for consultations and to take prescription medication. You can also request that physicians send email/text reminders for appointments.

3. INTRODUCE SMART DEVICES

 Introducing smartphones is a great way to increase self-reliance in those with reduced mobility, especially amongst seniors, who may be unfamiliar with them. Smartphones give even bed-bound patients a level of self-reliance by offering both a connection with the outside world, and the ability to request help at the touch of a button. This in turn fosters a sensation of security and lowers the need to have a carer present at all times, while also easing companionship.

4. DECLUTTER THE HOME

 Ensuring effortless movement between rooms is one of the best, and most straightforward, ways to encourage self-sufficiency in the house, both from an ease-of-use and safety standpoint. Remove anything which could induce trips or falls, such as mats and wires, and add additional lighting (and motion sensors) where necessary, to both inside and outside the house. For people with damaged sight, place vibrantly coloured tape to the edges of stairs for extra support.By making movement between rooms as smooth as possible you will not only increase the patient’s safety but also reduce the need for a carer to be present.

5. HAVE A CLINICAL ALERT SYSTEM IN PLACE

Having a trusted medical alert system in place makes it possible for senior citizens to carry on living autonomously, yet rest assured that if something was to happen, an alarm would immediately become activated. Medical alert systems are for that reason crucial in making sure that self-reliance doesn’t compromise safety. More Advice -

6. PLAN FOR SAFETY

Fall systems should also be in place as a safety measure, and specialist smoke alarms installed, especially if your patient has hearing or visual difficulties. Expert smoke alarms are wirelessly connected, meaning that if one is set off, all are triggered, and some even feature vibrating pads. Get in touch with your local fire and rescue company to go over these specialist options further.
