Battery safety problems for multiple EV manufacturers

Sat, 10/24/2020 - 18:13 -- Vic

As automotive manufacturers respond to tougher emission regulation by increasing their electric offerings, a number of them have been hit by a spate of battery safety problems. BMW, Ford, General Motors, and Hyundai have been affected.

BMW and Hyundai are recalling vehicles worldwide to address issues with battery fires in plug-in models.

Ford has delayed introducing its Escape plug-in into the US after fire safety concerns in similar models sold in Europe.

In the US, the Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) has launched an investigation into the Chevy Bolt EV after three instances of fires that originated without impacts from accidents. About 77,000 vehicles manufactured between 2017 and 2020 are affected.

Seaweed ‘could be surprise catch in extending battery lives’

A food additive extracted from seaweed could prove to be a surprise key ingredient to power advances in technology that could extend the lifetime of lithium-sulfur batteries, according to researchers in the US.

Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory say they have discovered that carrageenan, a derivative of seaweed, acts as a stabiliser in lithium-sulfur batteries – and improved stability could lead to more cycling and extended lifetime.
