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.

What i, Phones are Water, Evidence? What i, Phones are water resistant and how can you inform if your i, Phone is water resistant? The short response is: no mobile phone is water resistant, not even your i, Phone. And no, your Air, Pods are not water resistant, either. indicates that a gadget is entirely unbreakable by water.

As it stands, no mobile phone is water resistant. Your i, Phone may be.

Now we understand that there are no water resistant i, Phones, let’s look at which i, Phones are water-resistant and to what extent. Waterproof i, Phone Designs The first water-resistant i, Phones were the i, Phone 7 and 7 Plus.

The following releasesthe i, Phone 8, 8 Plus, X, XR, and the i, Phone SE (second Generation)all received an IP67 rating also. The i, Phone XS, XS Max, and 11 have an IP68 rating that allows them to withstand liquid invasion at an optimum depth of 2 meters for as much as thirty minutes.

The i, - Phone 12 and later on are the most water-resistant i, Phones Apple has actually produced up until now. Likewise with IP68 scores, they can endure being submerged in water as deep as six meters for thirty minutes. What’s more, every gadget from the i, Phone XR onwards is resistant to spills from other liquids such as soda, beer, coffee, tea, and juice.

Here’s how IP scores work: standard screening for water resistance does not supply a specific depth. IP68 merely implies the phones have been evaluated at depths more than one meter and discovered to be intact. Precise periods and depths are left to the manufacturers. Apple’s claims are, for that reason, likely to be more accurate than the IP rating.

Don’t. A brand-new i, Phone’s water resistance is guaranteed by seals and gaskets that obstruct the ports and other openings. These seals can compromise over time due to regular wear or tear, and there’s no concrete way of verifying that they are still effective. Apple offers no standards as to when this defense expires, so your i, Phone’s water resistance is truly as much as guesswork.

Doing so may end up damaging the protective parts of the i, Phone. If the damage appears serious, take your i, Phone to a specialist for repair work.

Depending on the model, the LCI is hidden in the i, Phone’s SIM slot or earphone slot. If the i, Phone has actually not had any contact with water, the LCI needs to be white.

Apple-approved - repair work cost a quite cent, but you can be sure that you will get what you pay for in the type of top-quality replacement parts and certified service technicians. If you do decide to take your i, Phone to a third-party provider, make certain to confirm that they effectively changed the sealant strips.

Want a Waterproof i, Phone? Get a Case If you wish to fortify your i, Phone versus all liquid invasion, your best choice is to get a waterproof i, Phone case. You can find sturdy water resistant i, Phone cases online, and they provide more defense than Apple’s vague water-resistance guarantees.

The i, Phone XS and the i, Phone XS Max are water-resistant. This does not indicate they are water resistant.

As the i, Phone XS is water and splash resistant, you can wipe tidy your phone, dry it off, and continue to use it as usual, but it is not recommended that you take your XS or XS Max for a dip in the swimming pool! What Does Apple State? Apple states that from the i, Phone 7 onwards the newest designs are splash and water-resistant.

Dry it off, provide it a tidy, and it needs to function like regular.
