Смысл: The main idea is that the Galaxy Note 7 explosions were a common technical failure amplified by media hysteria and competitor interests, rather than an extraordinary event.
The author argues that Samsung's Note 7 explosions were a statistical certainty of Li-ion technology, blown out of proportion by the media to benefit competitors like Apple.
Смысл: The text reports on Samsung's failure to resolve the Galaxy Note 7 battery combustion crisis, leading to the total discontinuation of the product to protect consumer safety and salvage the company's reputation.
Samsung has permanently stopped producing and selling the Galaxy Note 7 due to persistent battery fire risks and severe reputational damage.
Смысл: The text discusses a 2009 investigation by the European Commission into reports of iPhones exploding, warning that a single confirmed case could lead to a total ban of the device across the EU to protect consumers.
The European Commission threatened to ban the iPhone across the EU following an investigation into reports of devices exploding in several member states.
Смысл: The text serves as a technical post-mortem and product announcement, explaining how a real-world engineering failure (battery swelling) led to a more robust, feature-rich product through empirical research and a shift in charging philosophy.
Wiren Board redesigned their UPS from v.2 to v.3 to stop batteries from swelling by switching to 18650 cells, reducing the maximum charge voltage, and adding smart microcontroller-based management.
Смысл: The text illustrates the early reliability challenges of the Chevrolet Bolt's battery packs and the technical complexities of lithium-ion cell manufacturing. The main idea is that while EV technology is advancing, early production flaws can lead to critical failures, necessitating a close collaboration between manufacturers (GM) and suppliers (LG Chem) to refine industrial processes and monitoring systems.
A Chevrolet Bolt owner documents having two complete battery pack replacements due to manufacturing defects and interviews a GM engineer about the technical causes and fixes.
