Great study by TUM researchers on the powertrain of the VW ID.3
🚗 82% of energy losses are from drag (and it's not even a stupid pick-up truck or SUV)
🔋Energy density loss from cell -> module -> pack drops respectively from 273 Wh/kg -> 233 Wh/kg -> 173 Wh/kg. Huge opportunity for more dense #batteries through improved integration
👍 real-world cycles far outperform the mileage and operating time warranty https://www.sciencedirect.com/science/article/pii/S2590116822000133
Taiwanese battery maker Prologium said it will invest invest 5.2 billion euros in Dunkirk in northern France by 2030, and produce batteries for hundreds of thousands of cars there once at full capacity.
The group specialises in the development of "solid-state" batteries which are considered more powerful, safer and quicker to charge than the lithium-ion cells often used in electric vehicles.
Challenge accepted, w moim telefonie bateria po ~500 cyklach (2.5 roku) już słabo trzymała a była używana w zakresie 20-100%.
Teraz wymieniłem baterie na nową i włączyłem ograniczenie ładowania do 85%. Zobaczymy jak długo wytrzyma w zakresie 20-85%.
Researching and writing a column on the physics of meringue, trying to get it out of the way before a full weekend of Fully Charged LIVE discussing the future of clean energy and transport, batteries, EVs etc. I thought that no two topics could be further apart, but… this. Which apparently isn’t a piss-take. #meringue#climate#batteries
The Sodium-Ion Battery Is Coming To Production EV Cars This Year, Such As The Chery iCAR
Sodium is also abundant, but unlike lithium, is readily available. Sodium — one of the primary components of table salt — is chemically similar to lithium, and thanks to the explosion in lithium carbonate prices, many companies are researching ways to use it ...continues
