Explosions of electric bike and scooter batteries are on the rise, sometimes setting fire to homes and injuring occupants. The risk of overheating increases in summer, when temperatures soar. Even though the phenomenon remains rare, its consequences can be extremely serious. So it’s best to take a few precautions when recharging your battery.

The first thing to remember is to replace your battery as soon as it gets damaged in any way. The slightest shock or perforation can quickly cause a short-circuit. Likewise, if you notice that your battery is starting to swell, smoke or emit an unusual odour, unplug it and replace it immediately.

Lithium-ion batteries are particularly sensitive to heat, so avoid leaving them in direct sunlight during the day. Remember to put your ebike or escooter in the shade and, if you have a removable battery, remove it and place it in a cool, dry, and if possible well-ventilated place, with no flammable materials nearby. When it comes to hardware, always use the manufacturer's charger rather than a generic, off-the-shelf model purchased online. Be sure to follow the manufacturer's instructions when recharging your battery.

Finally, remember to unplug the charger once you've finished charging your battery. Leaving it plugged in for too long, especially in muggy, stormy weather, can cause it to overheat. And remember to unplug it before going to bed. As far as possible, always be present when recharging your battery.

In the United States, in response to the numerous cases of fires caused by exploding lithium-ion batteries, New York City has decided to launch a new experimental program of safe outdoor recharging stations. Initially, this initiative is aimed at bicycle delivery riders.

Meanwhile, more and more US college campuses are banning electric bikes and scooters altogether, in view of the growing number of fires caused by overheating batteries.
