EDTA Conference: Tesla Motors ready to license battery tech to other companies
Kelty told AutoblogGreen that he couldn't say much about Tesla's battery technology or the discussions, because everyone in the company is keeping things quiet. But he did say that to build a safe and reliable li-ion battery pack is a huge challenge, but Tesla has designed the 56 kWh, 366V li-ion pack with redundant active and passive safety features to prevent propagation of a "thermal runaway event" (often known as catching fire). Even if all active safety mechanisms malfunctioned, the thermal runaway event would be stopped by passive safety features. These features have helped the pack pass all eight UN battery tests. Currently, Tesla has 10-20 vehicles in Europe that are being crash tested with full battery packs.
