For the product enclosure itself; plastics that melt but won't catch fire are very common and readily available, even off-the-shelf enclosures from places such as Polycase can be made from them (it will be listed in the product details). This material won't contain the fire, but it also won't contribute to the fire.

Thats is very interesting to know! Thank you, MrSoftware. I would expect the design to be pretty well thought, for such a field of application, so it is somewhat reassuring.

There was a lot of work with the battery manufacturer to nail down the details.

 

Regarding flammability of the device itself; it may not be feasible to build something that can 100% contain the fire, but plastics that don't burn (they melt, but won't catch fire) are very common and readily available. Even off-the-shelf enclosures from a place like Polycase can be made from non-flammable plastics.

That is something I will look into, thank you.

 

For venting the enclosing case, the question is if it is intentionally sealed air-tight, or to be waterproof, or what? If there are controls or connectors that penetrate the case it is probably possible to have enough leakage in one of them to avoid a pressure buildup. That could be a cheap and easy approach.

Hi MisterBill2, and thanks for your comment!

The product is intended to be waterfroof. There is a connector on it, with a gasket that provides the sealing, which I would imagine could allow for some pressure to escape. But I wonder how much pressure would have to accumulate before that happens, for it to be a good enough option.

 

For an intentionally waterproof enclosure what can work quite well is a low-cracking-pressure check valve. It can be a smallone bcause the flow will be very low, but it will need to have a specified relief pressure. There are a few companies that make them. The "LEE"company is the first one that cones to mind.

Thanks for the recommendations, I will look into it!
