Do you know that you can spot 👀 a Porsche AG in Star Wars? Lucasfilm has asked Porsche to design a Starship 🛸 resulting in this Tri-Wing that you can see in the Series Obi Wan Kenobi 🤺 If you are familiar with #Porsche Design and in particular with their #Electric Vehicles 🚗 ⚡️ you can recognise some features of the Taycan such as Lights Now as for the propulsion, I am not sure they use a #Battery 🤔🤣 May the Force be with you on this May the 4th

Would you write some emails 📩 while your car cruise on the highway 🛣️ ? This is an interesting concept I filmed at the Chinese 🇨🇳 company Yanfeng Coupled with #EV Technology ⚡️such as Steer-by-Wire, coming #ADAS Level 4 (XPENG, Xiaomi Technology, ZEEKR极氪, Mercedes-Benz AG …) enables design and user experience option such as this folded “Steering Wheel” which can easily be switched into a computer keyboard 💻 or a game controller 🎮 In case you wonder about the Safety 🚨, the airbag is embedded in the seats 💺 and automatically deploy in case of an accident Another advantage of this solution is that you locate most of the accessories and features (airbag, loud speakers 🔊, etc.) in the seats for enabling Smart Manufacturing 🤖 in which macro-components are pre-integrated and rapidly mounted inside the final vehicle 🚗 I understand that many “traditional” people 👴🏻🧔🏻♂️ in my network will argue this will never happen in real vehicles but it is important to understand that 1️⃣ Young people like my son are interested only by this type of modern approach 📱 2️⃣ Asia and China in particular have a very modern vision on #emobility 🚗 in which the car is convenient for the passengers 🧑🧑🧒🧒 with new User Experience 👾 As always, I am interested in what you think…

Behind me is again one of these not very-well-known but key Technologies to produce high quality #Battery Cell 🔋 Few days ago, I had the privilege to visit NETZSCH Group and to discuss graphite spheroidization ⚫️ and grinding with Dr. Maximilian Muenzner Anode quality is highly influenced by the properties of Graphite particles such as their size 🔘⚫️, their ability to group / to disperse from one an other, their “roundshapeness” (no idea if this word exist but you got the idea!), etc. Rounding machines such as the one behind me (GyRho) allow to shape graphite flakes (left arrow) into micro spheres ⭕️ (right arrow) offering many interesting properties for the resulting anode (adhesion strength, pore size distributions, ionic resistance, etc.) which enables further #EV Battery 🚗⚡️ Technologies = fast-charging capability 🔌, long-term stability, etc.

It seems to me that many of you assume 🤔 that #Battery Packs are reduced to flat-floor packaging or simple rectangular 📦 boxes… So here are some more complex examples 🫶🏻 for you In addition to the packaging challenge, these complex shapes add a lot of other problems 🧠. For example when talking about vibration test 🫨, it is not always possible to bolt the Pack on the standard fixation of the vibration table (see for example the Battery of the #Electric Moto 🏍️⚡️ of Ducati Motor Holding As for passenger cars, I also put some examples in this video especially with the T- and H-shapes from the Maserati GT 🔱 and of course the Nevera from Rimac Automobili 🏁 Please note that none-square Packs do not necessarily use cylindrical cells 🪫 (even if there are maybe more common) and they also can use various Cooling strategies ❄️ (cooling plate, serpentine, immersion 💧, etc.)

Next chance to hear me presenting in this Wednesday in Stuttgart 🇩🇪 at the WeAutomotive Group conference on #Battery Innovation and Thermal Management 🌡️ I will talk about some unexpected consequences of Battery Cooling ❄️ on #EV Technologies ⚡️, Battery and Car Design 🚘, Manufacturing and more If you are around Stuttgart this week, do not hesitate to message me Want to see me there?

Today, i have hit 1000 consecutive days of learning Chinese 🇨🇳 on DuoLingo and here are my lessons so far: I started Chinese with an objective to help me learning on #Battery 🔋 and #EV ⚡️ Automotive and it has been hugely useful for me! I am often on Chinese websites 💻 or videos and I find there a lot of useful information I have set up a strict routine ⏱️ with between 5min and 20min of Chinese every single day including Xmas or if I am ill or tired I find learning Chinese easiest than what I initially thought. It is really fun 😀 and the grammar is very intuitive. Reading is not so hard if you have a visual memory 👀 like me but pronunciation is a nightmare 😭 It is super interesting to learn a none-western language + it helps to understand culture differences 🧧, philosophy and mindset I have still a very long road before I can fully talk and understand Chinese 💬 but I do not care…the journey of learning is more valuable than the final goal ☺️

Want a summary 🗒️ of the #AutomotivePhotonics organised by TRUMPF last week❓I’ve got you! The day was organised around 4 Conference Sessions, various LIVE-demo and of course Networking 🫱🏻🫲🏼 Some take-aways: ▪️According to Roland Berger, only a fraction of the announced European 🇪🇺 #Gigafactory will be realised and successful in the market ▪️Scale-up 📈 but even more importantly lowering Scrap-level ❌ is challenging. Manufacturing Suppliers with #Battery production experience are Keys ▪️ACC - Automotive Cells Company insists on speeding up production ↗️ rather than continuing line-demo 🎓 ▪️Laser Welding 🎆 is used at many stages of Lithium Cell 🔋 Manufacturing (Tab, Can, Venting, etc.) and associates accuracy, reproducibility, low contamination, speed, etc. ▪️Laser Welding is also used in many Battery Pack Components such as the Battery Cooling plate 🔲, the trail structure, etc. ▪️For the Chassis and Car Body 🚗, #Gigacasting (Tesla, etc.) is definitely a major trend (Thomas Ausmann, Gestamp,…) in which Metal quality ⚛️ such as Steel (ArcelorMittal …) and Laser Welding and laser Cut play crucial roles ▪️Laser Welding machines 🎆 are evolving combining modern Technologies such as automatic visual inspection 👀, high automatisation but also #AI 🧠 ▪️Laser Applications in #Automotive 🚘 are not limited to Welding, they also support many production methods (part cutting, cleaning, etc.) but also enable many New technologies such as metal coating or #3Dprinting Feel free to contact me if you have any questions 📩 Thanks Daniel Maier and Jeanette Thumm from Trumpf for inviting me

Why and how do we study vibrations 🔋〰️ on #Battery Cells / Modules and Packs? In this video, software analysis 💻 for the long module test is from Siemens Mobility while the full #Electric Vehicle Battery Pack 📦 Test was filmed at Emitech Group 🇫🇷 Of course in addition of this quick introduction, there are many different vibration tests depending on your homologation target (🇪🇺🇨🇳🇰🇷🇮🇳…) And of course vibration tests are only a part of the #EV Battery Tests 📑 Do not hesitate if you have any questions, I have got a full review of Battery Testing and homologation

How is made this #Battery Cooling Plate? 🤔 Is that brazed? No… it fully #Laser Welded 🎇 Today I am busy at #AutomotivePhotonics organised by TRUMPF and I cannot wait to see the live-demo of this huge Cooling Plate 🔲 for #EV being welded Do not worry, I am collecting many cool videos 🎞️ and information on Laser Welding Applications for #Battery 🔋 and #Electric Technologies 🚗⚡️ and Manufacturing Thanks Daniel Maier for your time and your explanation yesterday and thanks Trumpf for inviting me 🙏🏻

This is the Xiaomi Super Colossal #Press able to apply 9,100 tons weight for the “HyperCasting" of their #EV Parts 🚗⚡️ This is even bigger than the 9,000 tons IDRA presses used by Tesla 🤯 Xiaomi even claims that the machines are actually capable of delivering 9,500 tons of clamping force 💪🏻 Xiaomi has self-developed its own Aluminium alloy which doesn’t require heat treatment ♨️❌, the “Xiaomi Titan Metal” (CN117327949A) According to Xiaomi, the alloy is excellent in die-casting performance, mechanical properties, durability, recyclability, economy, and it also adds 40% recycled aluminium ♻️ Cannot wait to discover more about their detailed #Battery and eMotor technologies as well as all their manufacturing processes, exciting time 😍!
