here are now one million EV vehicles on the road in the UK, many more internationally, and the


global demand looks set to increase exponentially. However, there are specifi c safety concerns for an EV, particularly when their batteries are exposed to water or following a crash. In short, electric car batteries require management to ensure safe

performance and avoid thermal runway.


SAFETY STANDARDS As most industry engineers will be aware, EVs must pass the same safety standards as internal combustion engined (ICE) cars, meaning that they are just as safe in the event of a collision. Cars are crashed and assessed by independent safety body


Euro NCAP, which awards an overall safety rating for each car it tests, allowing drivers to identify the safest choice for their needs.


COMPONENT PARTS EV car manufacturers, however, are looking to components manufacturers to help manage pressure within the battery to ensure safety. One component manufacturer, Freudenberg Sealing Technologies, has seen enormous demand for a product called the DiAvent HighFlow in recent months, with the company claiming to have received multiple major orders from one Asian and one US automotive group. This led to the
