An airbag for battery packs: PyroPhobic says its unique thermoplastics will stop thermal runaway

Engineers have been searching for ways to mitigate the risk of fire with Li-ion batteries since the technology was first commercialized. Chemists are creating new cell formulations that are less prone to problems, electronics experts are designing fail-safe battery management systems, and mechanical engineers are building complex cooling and fire suppression systems. A common rule… Read more »

Will America maintain its EV lead?

Here at Charged, we believe EVs are for everyone, regardless of political leanings. While we certainly comment on government policies that we feel are pro- or anti-EV, we avoid endorsing any particular candidate or party.

In the first half of 2016, BMW’s four plug-in vehicles – the i3, i8, X5 xDrive40e and 330e iPerformance… Read more »

Engineered Materials Solutions brings a century of clad metal experience to batteries

The methods that automakers use to join Li-ion cells together are almost as diverse as the sizes and shapes of the cells themselves. EV builders are using spot welding, mechanical fasteners, wire bonding and other joining techniques. It’s safe to say that there is no consensus on an ideal solution, and that there’s a lot… Read more »

eluminocity combines street lighting and EV charging to save costs and enable smart cities

The EV of the future will be a mobile part of what some are calling the “smart city” – an integrated network that ties together EV charging, renewable energy generation, energy storage and various devices that control everything from escalators to crosswalks to streetlights. These devices depend on sensors and control circuits that keep track… Read more »
