Samsung SDI signed a multiyear electric vehicle (EV) battery supply agreement with Mercedes-Benz Group AG in Seoul on Monday. The deal marks the first such supply contract between the companies, providing high-performance batteries for next-generation EVs. The firms also agreed to expand cooperation in future mobility, including joint development of advanced battery technologies.

Used batteries from electric vehicles could fulfill two-thirds of China's grid storage requirements by 2050, according to a study by researchers at Tsinghua University. These second-life batteries would charge during periods of abundant renewable energy and release power during peak demand. The approach could reduce costs by 2.5 percent while supporting a shift to carbon-neutral power systems.

Eine Geotab-Studie untersuchte 22.700 Elektrofahrzeuge und fand heraus, dass häufiges Schnellladen die Batteriedegradation auf bis zu 3 % pro Jahr ansteigen lässt. Trotzdem bleibt die Batterielebensdauer lang, mit einer Kapazität von 80 bis 85 % nach acht Jahren. Faktoren wie Klima und Nutzungsgewohnheiten beeinflussen den Verschleiß.

A recent recall of over 10,000 Tesla Powerwall home batteries due to fire safety concerns has prompted recommendations for alternatives. Electricians have long praised the Tesla Powerwall for its sleek design, but long wait times and other factors are driving interest in competitors. The article lists several options from brands like Bluetti, Enphase, and GM Energy.
