I came across this charger and honestly can't identify it. If you have seen it before or know the manufacturer / model, I would really appreciate your feedback / help here. 😄 🙏 CPO: Electra Charger: 24 kW DC, possibly with a Type 2 socket as well (not sure on this) Pic credits: Electra

The biggest EV charging news this week. It involves IONITY, Ekoenergetyka, 6 incidents, insurance claims and learning points for car OEMs, CPOs and charger manufacturers. I had never heard of such an incident before, and therefore decided to look into it. IONITY has 901 sites and many Ekoenergetyka 350 kW chargers. But IONITY Elverum (Østerdalsporten) in Norway is the only site listed at 500 kW: Ekoenergetyka’s shared-power pilot, opened in December 2025. Setup: 2x DLBS power cabinets, 3x Sat 400 dispensers, 6 charge points, up to 500 kW per car (usually rated at 400 kW, but perhaps boosted to reach 500 kW here). The incident: IONITY received six incident reports from the site. The cars’ pyrofuses fired, the one-way switch that cuts the battery off in milliseconds. IONITY told Adressa the charger manufacturer confirmed a fault, and the chargers will be replaced in a week. Looking at the site, yes, they are all offline. I am not sure, however, since when. One incident: An ID. Buzz owner heard a bang ten minutes into charging. The car never started again. It has been at a workshop since June 30. The repair bill is roughly €10,700, and the insurance question is still unresolved for over 3 months. But here is what I think we should look at: - Charger manufacturers: if the car’s pyrofuse stopped the fault, the charger’s protection didn’t. The charger’s protection must be robust and must always work. - Car OEMs: a pyrofuse might fire one day. How much it costs to replace is a design choice. The ID. Buzz bill suggests a deep repair. In a Tesla, it’s reachable from the interior. - CPOs: the driver trusted a public charger installed and operated by you, and they shouldn’t be left stranded. I understand this is a new area, but there should be an approach for how insurance will play out. Should the CPO pay, the charger manufacturer or the car OEM? I am not an expert, but the customer needs support, and there should be a way to a faster resolution. I still don’t know exactly how this happened, since chargers have their own protection. If you do, I’d like to hear it. Thanks @RoamingNorway for sharing this. Thanks @electricfelix for sharing the ID Buzz Owner's son post on this topic👇 lnkd.in/p/ej9a_yzn
An IONITY station in Norway killed several EVs by blowing their pyrofuses. 6 cars in total were affected. The site is IONITY's only Ekoenergetyka pilot site in Norway. I just checked, and all the Ekoenergetyka chargers there are unavailable, while the Alpitronic charger at the same site is still live. Source and photo: adressa.no

At the beginning of September, EnBW opened a new charging site at its headquarters in Karlsruhe, and I visited it today with @etechvolution. Personally, I wondered what the added value of this hub was, given that there is another EnBW location about 1 km away, at a shopping center that also has restrooms. My initial thought was that, outside of the shopping center's operating hours, it wouldn't make much sense to charge here. However, having now visited the site, I noticed that several people use it while they walk to nearby shops/stores that aren't in the nearby shopping centre, which explains why the site sees a decent amount of usage, especially during shopping hours. EnBW has already carried out preparatory work to expand the site, should demand prove high enough. @EnBW @PaschekBernd

I’ve never seen a work ethic like China’s. Not even close. Let me start with cleanliness. In the cities I visited (Beijing, Hefei, Shenzhen, Chengdu, Fuzhou), it was mind-blowing, whether it was the streets, hostels or train stations. The best example of their work ethic came during the public holidays (May 1-5). I saw the streets being cleaned as late as 10 PM and as early as 6 AM. Mind you, this was Huaqiangbei, one of the busiest areas I have seen in China. Then, for the first time in my life, I saw a 24/7 restaurant. It was open at 3 AM when I arrived, with really great food and hospitality. I also had the pleasure of visiting factories and meeting a lot of industry professionals at Auto Show Beijing. In Chinese Tech Industry, there’s a famous saying, “996”: 9am to 9pm, 6 days a week. Not everyone works like that, but I saw people working until 8 PM on Tuesdays and Thursdays, and at times on weekends and holidays during crisis situations. Hours most engineers and professionals here can’t even imagine. I am not saying it is healthy, or that it is the best way. But one cannot deny their speed and their work ethic, and it is no wonder they are now dominating technologies that, 20 years ago, no one thought they could. The automotive industry is the prime example. And now AI is everywhere. I even saw older people being taught how to use it. The whole country seems all in. Here’s a small example.

Everyone in EU knows about XPeng’s next gen EVs & autonomous driving. Very few know that it operates chargers in China. Gen 1 and Gen 2 👇 When I visited China in spring, I saw it firsthand. XPeng doesn’t just build cars, it builds and runs its own charging network, with split chargers: In Shenzhen, I found two types of dispensers side by side, connected to 720 kW power unit: → A single-gun dispenser, liquid cooled, rated for 720 kW. → A dual-gun dispenser, 250 kW per side. And behind me, a beautiful XPeng P7+. In Beijing, I came across an older generation of their chargers. These were connected to a 360 kW power unit. I think we are going to the next gen soon. I saw a teaser at Power2Drive earlier this year, but I first need to research on it further. ____ I'm Haseeb. EV Charging Consultant based in Germany! If you want to understand how all DC charger manufacturers competing in EU, are lining up against each other, where they are winning and losing out. I am preparing a comprehensive report on exactly that. Reach out if you are interested. Happy to show it!

BYD Flash Charging vs NIO Battery Swapping during Golden Week 🤯 Every second, ca. 2 cars were flash charging at BYD and 2 were swapping batteries at NIO. Golden Week (Oct 1-7) is among the busiest weeks for charging in China, with holidays and people traveling across the country. BYD Flash Charging: → Total installed: 12,165 stations → Total sessions: 1.22 million → Peak sessions/day: 188,344 NIO Battery Swapping: → Total installed: 4,168 stations → Total swaps: ~1.19 million → Peak swaps/day: 183,664 NIO nearly matched BYD’s total volume, with only a third of the stations. On the peak day, each NIO station did 44 swaps vs 15.5 charges per BYD station, nearly 3 times more. I think BYD could have done even more, but there was so much traffic that many stations couldn’t deliver MW or fast charging. Once the station batteries drained, the power came only from the grid, and charging slowed down. More on it in the coming days 😄 But the sheer numbers are a thing to watch. Thank you @liumiao for sharing the numbers 👏
BYD and Nio have each released figures on how their Flash Charging and battery-swapping networks performed during China’s busiest holiday period, the National Holiday. The data show that battery swapping was about three times as efficient as fast charging. Report link below.

That brake incident had a huge impact. JAC shares hit the 10% daily limit down two days in a row. Drops this severe are rare in the auto industry. The closest I can think of are VW Dieselgate and the Ford/Firestone disaster in the early 2000s, which caused casualties and injuries across the world. Back then, Bridgestone fell 18% in two days and lost half its value within a month. Ford dropped up to 18% in three weeks. That crisis was far worse than what we are seeing with the Maextro V800, and it ended in huge lawsuits, settlements and penalties. Safety failures are not a Chinese problem. They unfortunately happen in this industry. I experienced a brake failure campaign first hand at an EU OEM, which led to a recall of over 100k cars. The test is how a company responds. A strong response can raise standards for the whole industry. The winners are consumers. P.S. I still cannot believe the post got 700k+ impressions. I never get more than 1k, and I posted it expecting the usual.
Part 2: Technical Breakdown. Why did 3 brake pedals snap during emergency braking on the Maextro V800? (ENGLISH SUBTITLES) - 🇨🇳 All 3 broke at the exact same spot: the plastic bracket holding the pedal. Same fracture, “broken like triplets.” The material isn’t the problem. Another car uses the exact same plastic, from the same supplier, and survived 6 full emergency stops. The difference is design. The V800 pedal sits furthest from the pivot (130 mm), so it takes the most load, yet it has only 1 reinforcing rib. Others have 2 to 3 per side. Plus a weld line right in the highest-stress zone. I have never seen this level of explanation in a car review. Huge credit to Dongchedi. Glad they found it now. The V800 only went on sale in August 2026, so not a lot of cars would be in the market yet. Video Credits: Dongchedi. I translated and added the English subtitles myself. Source in thread 👇

The biggest news from China’s car industry today. 3 brake pedals during emergency brake tests on 3 brand-new, luxury class Maextro V800s. (ENGLISH SUBTITLES) Maextro is Huawei’s luxury brand with JAC, and the V800 sells for 0.77 to 1 million RMB. Massive credit to Dongchedi, the company that tested the cars. They are, I believe, China’s most renowned and respected third-party testing platform, and this video shows why. 3 new cars, pedal force sensors on the third attempt, cameras everywhere, a closed track, a drone and a safety crew. This is among the highest levels of independent car testing I have seen anywhere. The force when the third pedal broke was 1612 N. I am not sure on this one, but from the limited posts I read, it seems China’s industry standard requires a brake pedal to hold 2000 N for 5 seconds. This had a huge impact on the company. Today JAC’s stock fell by 10%. P.S: I just translated the video and added english subtitles. Video Credits: Dongchedi, Sources in the thread 👇

One clarification: Huawei supplies the OS and I think ADAS as well. JAC is the OEM here and hence its stock fell down.

73,000 to 154,000 km on the clock. Only regular maintenance 🇨🇳 I didn’t expect this post to get so many impressions. One bad test from one OEM doesn’t define every Chinese OEM. Here’s what I saw on the ground. These are DiDi ride-hailing EVs (DiDi is China’s Uber) I photographed in China in April 2026. All local Chinese brands. Not luxury cars, but basic trims, cars for the masses. The drivers were extremely satisfied with how robust their cars were. They never needed a workshop visit outside regular maintenance. xitter.cf/etechvolution/status/2…

Europe has cable theft. The USA has quick-release adapters. And China has its own set of charger safety issues!

This picture is 6 years old. Does anyone know anything about this charger? The site has an Alpitronic now. But look at it. The old EWE logo, and probably the earliest BESS I have seen installed next to a DC charger. Pic credits: Google
