Total Energies Lubrifiants, the lubricants arm of French energy giant Total, has fitted a Renault Megane E-Tech with an immersion-cooled battery that uses a new fluid called Cell Shield – and is claimed to have halved the EV’s charging times and extended its range by 6%.
Immersion cooling is a conveniently obvious term: reducing the temperature of something by putting it into a fluid.
But where electrical components are concerned, that’s not as simple as it sounds, as introducing water-based fluid to the circuitry of any electrical device causes a short circuit and instant destruction. This is why EV batteries are waterproof.
