I could't sleep well thinking that I could be one of the unlucky e-bikers that burned their garage or even the whole house due to a faulty battery or a bad overcharge. I always charge during the day, but even then, there couldn't be much I could do if one of the batteries set on fire and exploded.
I have two batteries, the standard one that came with the bike and an added more powerful battery that I have it in a carrier bag on the rear rack. I have arranged it so I use one till it is almost empty and then via a three way switch I select the second one. I basically have doubled my distance I can ride in one go.
Anyway I set up to fabricate a safety container where I could charge either battery with a 50% chance of saving my home. The way these batteries burn/explode, is something no one would like to experiment in their garage, because the ammount of energy originated during such an event is quite impossible to control, let alone if you have no barrier between the battery and the surrounding elements.
For that reason and seeing how others tackle this problem I purchased all the necessary elements, being the container or box the most important barrier. It cannot be totally sealed because in case of fire and explosion, the case would also burst, allowing the internal fire to reach all the surrounding areas. I purchased a Bosch tool box, big enough to fit both my batteries if needed. Made 6 x 33mm dia. holes on the lid and then proceeded to use the mesh to avoid the ceramic matt to just blow through the holes. I used high temperature silicone based glue to old the ceramic matt in place and that was the worst part of the job, bacause the matt tends to peel into several layers. Finally I covered all sides (except for the lid with a thin coat of fibreglass and teflon, designed to use on to of grills and barbacoas,
If at some stage the whole thing catches fire, in the end there won't be much left to salvage, but cross my fingers in the hope that my garage and home are not badly affected.
I include images of all I used to make this little bunker.
Best regards,
