E-bike fires up 78% in a yr in accordance with the London Hearth Brigade – here is how you can hold your battery protected

E-bike fires elevated by a large 78% final yr in contrast with 2022, in accordance with the most recent knowledge from the London Hearth Brigade (LFB), which has launched its #ChargeSafe marketing campaign to attempt to management the issue.

The capital noticed 155 e-bike fires final yr, and 28 e-scooter fires, whereas combustion of lithium-ion batteries from bikes is now the quickest rising trigger of fireplace. Batteries and motors that don’t meet UK security requirements are responsible, in accordance with the LFB. 

Are e-bike mountain bikes on the hook then? Virtually actually not, we’re happy to say, as a result of the greatest electrical mountain bikes have in-built failsafes to minimise the probabilities of them burning up. It’s the counterfeit batteries or low cost conversion kits purchased from on-line marketplaces which are responsible, in accordance with the LFB.

Nevertheless, having a giant battery pack stashed in your own home is statistically going to extend the possibilities of a hearth. That’s as a result of defective or broken batteries are at better danger of setting alight, and mountain biking does put batteries in hurt’s approach. Accidentally utilizing the mistaken charger is doubtlessly harmful too. 

E-bike security have to know, from the London Hearth Brigade

  • Retailer your bike in an exterior location, ideally a shed, storage or outbuilding. If that’s not doable, hold it out of thoroughfares and hallways
  • Use the proper charger to keep away from an elevated danger of fireplace. It’s because completely different motors require completely different voltages
  • Don’t convert your analogue bike into an e-bike with a DIY package… though that’s in all probability a given for correct mountain bikers

  • Examine for indicators of malfunction – it may very well be sizzling to the contact or have modified form

What’s inside an e-bike battery

Lithium-ion batteries are made up of rows of cells, packed into a troublesome and rigid casing. There’s additionally a Battery Administration System (BMS) or maybe a number of BMSs caring for teams of cells, and that is the essential bit to a high quality battery.

The BMS controls how the battery discharges while you trip, it’s the software program that tells the battery what number of watts to place out, when to enter limp mode and when to close down. If there’s an error it’ll talk that to your show too. 

And not using a BMS (there are a lot with out them) you possibly can discharge a battery an excessive amount of, or overcharge it too, which results in a chemical imbalance and doubtlessly a fireplace. This could additionally result in one thing known as thermal runaway, a cell overheats and results in a chemical response that in flip overheats the subsequent cell, and so forth.

How you can take care of your battery

In case you’re driving a motorbike from a good model and plugging it into the correct charger then you possibly can relaxation simple in regards to the BMS. However there may be another approach a battery can fail, and that’s mechanical – you and crash and harm it. This implies you might want to examine your battery often. And, simply to be on the protected facet, don’t depart the bike plugged in and charging in a single day.
