As we require bigger and bigger batteries - charging them becomes an increasingly risky proposition.
For your consideration - here's a charging station that might mitigate the risk involved.
A steel drum and some concrete blocks. The block goes in the bottom of the drum, the battery goes inside the block. A piece of metal window screen goes over the top of the drum
In the event of an explosion the drum contains the fire - and the screen stops the flames.
Anyone have the equipment to test this concept? This would make a good youtube video.
