    Crash-safe Battery Protection for Electric Cars

Everyone is talking about electric drives, and the scientists from Fraunhofer are also working on them. Engineers have replaced a battery box for lithium-ion batteries with a lightweight component. Not only does the housing save weight and sustain no damage in an accident - for the first time ever, it can also be mass-produced.
In a joint effort, experts have developed a mass-production-ready, crash-safe battery housing that meets strict requirements. The battery housing that surrounds the battery that weighs 340 kilograms (749.57 lbs.) only weighs 35 kilograms (77.16 lbs.).
"Traditional solutions made of steel weigh up to 25 percent more," said Manfred Reif, project manager in the joint project "Fraunhofer System Research for Electromobility." "The battery housing can withstand a crash, assuming a ten-fold gravitational acceleration." And even if a sharp object collides with the housing at 60 km/h (45mph), the highly sensitive battery on the inside remains intact. In addition, the 16 lithium-ion modules are protected from humidity, and a semi-permeable membrane to equalize pressure also guarantees that the batteries are able to "breathe."
