EV BATTERY TEST & ASSEMBLY AUTOMATION – WHY INVEST IN IT NOW? 18.10.2021 EV Battery Test and assembly automation are key factors in bringing about higher quality manufacturing of products but also in allowing people working in production to achieve greater feeling of meaning in their work through more varied job functions, increased safety and improved work ergonomy. We believe these are issues we can tackle in true JOT fashion – Just On Time. The discussion around automating manufacturing processes has evolved significantly from what it was when automation was first brought to the table. And with the rapid development of automation solutions, the concept of automation itself has to be continuously updated. The development has been so dramatic that what previously constituted simple processes and mechanical tasks has expanded to include e.g. smart production systems, AI-based solutions and even predictive manufacturing. All in all, automation has evolved to a place where it enables local jobs and improves job quality. Still, even as automation has become to be seen as an enabler, there are still warped expectations and perceptions of what the cost of investment in automation is. The perception becomes exceedingly warped when talking about industries with extremely high production volumes, like for those manufacturing electric car batteries – which are becoming increasingly prevalent, as it seems to be where the future of mobility is headed. Fortunately for you, we are able to highlight some of the advantages of investing in EV (electronic vehicle) battery test and assembly automation. In a nutshell, some of the main reasons to invest in EV battery test and assembly automation are 100 % verifiable tracking throughout the production line Lower lifecycle costs Improved safety Increased speed and consistency in production Leveraging these advantages through automation is possible at any point of your production cycle. For the best results though, the earlier automation can be brought into the product design process, the better the end product – as well as cost efficiency, but we’ll get into that later. Remember, however, that these are just some of the reasons – we’re more than happy to hear more about your needs, if you care to share! TURN EV BATTERY PRODUCTION CHALLENGES INTO YOUR COMPETITIVE EDGE EV battery manufacture has plenty of challenges, all of which can hinder production in different ways. As it happens, automation is such a multifaceted solution that its different aspects are perfectly matched to solving these challenges and even give you an advantage. One of the – literally – biggest challenges in EV battery test and assembly is the size and weight of EV battery modules. As the modules weigh in at tens if not hundreds of kilograms, manual testing and assembly gets really cumbersome, often requiring specially designed lifting systems. In addition to the required extra equipment, the handling of heavy loads in large, varying shapes is a constant health and safety hazard with added poor work ergonomics in manual handling of the modules. Test and assembly automation works wonders in addressing these issues however – an automated test and assembly line takes care of all the heavy lifting for you. This means no more heavy lifting with specialized rigs or worrying about dropping heavy and fragile battery packs. An investment in test and assembly automation thus also becomes an investment in your employees’ well-being along with increased job meaningfulness. And why would you say no to that? Another issue with EV battery test and assembly is quality assurance and tracking. It’s a given that when humans work, there’s also room for human error. Mislabelling, mishandling, any other mishap – something will happen sooner or later. Humans also have a limited capability for certain tasks that require incredible accuracy, e.g. measuring an object’s dimensions or temperature quickly and accurately. Any one of these issues influence a manufacturing operation greatly – if not already on the production line, then after being delivered to your customer or even to the end customer. And by then, any small issues in quality – faulty battery packs, damaged battery modules, smallest impurities, and so on. – become hefty costs either through compensation, repair or even massive-scale callbacks. Not to mention, defects in battery cells, packs or modules can be hazardous to their operating environment, and any possible damage at that point isn’t measured in monetary terms. With an automated EV battery test system and assembly line, however, you get rid of these challenges altogether. Not only are automated test units able to handle individual battery cells, battery packs and even battery modules with supreme accuracy, they are also capable of conducting performance tests and calculations at superhuman levels, tirelessly around the clock. This means automated testing lines are able to optimize battery packs and modules on their battery cell level to achieve maximum capacity and minimum downtime– allowing you to deliver battery modules with uniform performance and consistency like no other. Automated test and assembly with JOT’s solutions also means using machine vision that can measure and detect even the slightest abnormalities in battery cell or module dimensions. Throw in dedicated temperature sensors that detect even minimal changes in temperature, and you have a combination that ensures uniform performance and consistent high quality. These solutions in turn make it possible to react to possible battery malfunctions before an accident happens – if a modern EV lithium-ion battery malfunctions, the chemical reaction increases the battery’s internal pressure, causing bulges that may not be immediately visible to the naked eye. Another thing an automated testing line can detect earlier is the rising temperatures caused by chemical reactions, which at first can be minimal and undetectable by a human handler. But the earlier a malfunction can be detected, the more time there is to react and the more safe the production line becomes by proactively minimizing any potential risks. The added benefit of course – just as with detecting other faults – is to be able to avoid assembling and shipping faulty battery modules that down the line cause large callbacks and other additional costs, and to ensure your production downtime is at a minimum. THE PRICE IS RIGHT – AND DECREASES RELATIVELY THE MORE EV BATTERIES YOU MANUFACTURE Like in any manufacturing business, the relationship between cost of production and quality of products should be optimized. Thus any large acquisition of new production equipment and infrastructure can seem initially too costly to invest in. But, instead of looking at the initial lump sum, your focus should be in what’s left in your bottom line – and how not investing in test and assembly automation can actually diminish your bottom line. So let’s put things into perspective: a single EV battery module contains thousands of single battery cells, thus manufacturing thousands of battery modules equals millions of single battery cells. Thus, investing into a JOT Battery Test Solution means your cost per tested battery cell is, at the very least, calculated in cents, and at best, in fractions of cents. This means that, over time, your ROI pertaining to EV battery test and assembly automation keeps on getting better and better. And once you factor in the potential costs that repairing or calling back faulty battery modules brings, the more you get out of your investment. JUST DON’T THINK WE HAVEN’T GOT YOUR BOTTOM LINE IN MIND! JOT’s automation solutions also have an advantage that keeps serving your bottom line – and that is longevity. As in any electronics manufacturing, EV battery manufacturing evolves constantly, product dimensions vary and components change. With JOT automated Battery Test Solution, 90% of the initial investment is for the infrastructure and the rest is customized parts. This means, in the future when you need to change or upgrade your test or assembly lineup to be compatible with your new products, you only need to invest that 10% of the initial investment to customize your pre-existing production platform. With that minimal investment done, your waiting time is counted only in weeks instead of months – which happens when you start production from the ground up. After just a matter of weeks, you’re up and running again with an updated product test and assembly line, saving you time and – again – money.
