Nobody wants water leaking into electric car battery packs. But keeping them dry can be a challenge, says Thomas Parker, North American automotive sales manager for Inficon Holding AG, a global leader in leak testing.

That is especially true as carmakers adopt “skateboard” designs that mount batteries under the floor, where they are exposed to rain water. Parker notes that immersion tests aren’t practical on the production line, so carmakers are turning to robotics and helium tracer technology to deliver consistent test results.
