Lithium Battery Charging

Both of us have e-bikes.  To be strictly correct Jan has an e-trike.  Like almost every e-bike battery. ours are made in China.  No doubt you have probably read or watched one or more stories about lithium battery fires and how intense they can be. 

It's for this reason that we don't recharge our bike/trike batteries inside.  Nor do we recharge them in the garage, where there a plenty of highly flammable items.  Another thing we don't do is leave the batteries on charge overnight or whilst away from the property.

When looking for an initial location to recharge the batteries I opted from the most logically and accessible power socket on the exterior of the house.  It happens to be under the pergola by the back door.  It's a power socket I installed in anticipation of us changing the gas instant hot water heater to one that was electrically ignited.

This was only going to be a temporary solution as recharging the battery near a gas hot water system obviously carries risks.

I decided to install a new power socket in the middle of the underside of the pergola roof.  Charging lithium batteries here would mean they are away from anything flammable and on concrete pavers.  If a lithium battery fire occurred here it would be very intense but not likely to burn down the house.

The right arrow points to the new double power socket and the left arrow to the PVC conduit which takes the cabling from the new power socket back to the house soffit lining.  From there the cable goes down the wall cavity to the power socket beside the gas water heater.  The job has taken me half a day.
