- Fires began by lithium-ion batteries in Teslas, e-bikes, and scooters proceed to make nationwide information, prompting customers to surprise if electrical propulsion is unsafe.
- Nevertheless, firefighters and regulators say these fires usually happen from counterfeit batteries and negligent charging behaviors, not an inherent defect of lithium-ion batteries.
- Consultants say further laws and business requirements, reminiscent of UL 2849 for e-bikes and e-scooters, would forestall fires and restrict their severity.
Lithium-ion batteries are fueling the auto business’s conversion to battery-electric automobiles, however they’ve additionally been a catalyst in a sequence of transportation-related fires which have halted pickup truck manufacturing, burned down a neighborhood grocery retailer within the Bronx, and compelled an emergency touchdown due to a smoking overhead bin on a business jet.
Fires have additionally allegedly been began by electrical bicycle battery packs. The New York Metropolis Fireplace Division says lithium-ion batteries had been answerable for over 200 fires inside the 5 boroughs in 2022, leading to six deaths and over 150 accidents whereas displacing 1000’s of residents. That is double the variety of battery-related fires as in comparison with 2021, in response to an FDNY assertion to NBC Information.
It isn’t only a drawback for city, dense cities, both. A Connecticut Transit electrical bus caught fireplace on the company’s suburban depot in Hamden final summer time, and firefighters elected to let the bus burn because the most secure strategy to handle the blaze. Electrical scooters have sparked fires and leveled houses in rural Massachusetts and Pennsylvania. Even Ford needed to briefly shut down Michigan manufacturing of its battery-electric F-150 Lightning pickup truck as a result of a fireplace in a pre-production holding lot. And the way may we overlook the varied EV-related ship fires that in the end scuttled the cargo of 1000’s of automobiles?
Evaluation of fireside and crash knowledge from the Bureau of Transportation Statistics and the Nationwide Transportation Security Board present there have been 1529.9 fires per 100,000 gross sales for gasoline automobiles and simply 25.1 fires per 100,000 gross sales for electrical automobiles. However the greater concern is the variety of fires linked to gas-electric hybrid automobiles: 3474.5 fires per 100,000 gross sales.

Analyzing the speed of electrical automobile fires does not inform the entire story. For one, lithium-ion battery fires burn another way than a conventional gasoline fireplace, with the blaze lasting longer and burning hotter than a gasoline fireplace. Because of this, fireplace departments throughout the globe have begun educating themselves and the general public about easy methods to cope with this new fireplace phenomenon. Even so, nearly all of blame for these harmful fires is not on the producers of high quality batteries.
In actuality, uncertified batteries which are being charged with out supervision or to not the producer’s specs are the frequent thread in most of those fires. Because of the excessive price of legit battery packs and the ubiquity of two-wheeled electrical automobiles as city supply instruments, many supply staff are compelled to buy cheaper, unregulated batteries and proceed recharging them previous their prime. However, as Vice President of Bosch’s E-Bike division Claudia Wasko put it, attempting to restore and recharge abused battery packs is a big security threat.
“There are completely different opinions and methods of certifying that the battery is a really fine-tuned excessive complexity system, and the elements are underneath sure circumstances flammable,” Wasko instructed Autoweek. “Throughout the UL 2849 programs, you certify or take note of electrical shock and dangerous conditions regarding the battery. The testing necessities cowl any type of system mixture, and the system consists of a drive unit, the battery, the show, and any interconnecting cables.”
The UL 2849 certification system is a brand new security criterion from the US Client Product Security Fee that covers battery electrical e-bikes, e-scooters, and lightweight electric-vehicle battery packs, and it could possibly be a serious driving pressure within the secure rollout of electrical mobility know-how. The usual classifies e-bikes by battery and drive-motor traits in addition to units a testing normal that requires a fireplace security certification of the battery itself and in relation to different supplies and elements of the automobile. The UL 2849 normal stays voluntary at the moment however is meant to attenuate the outbreak and the severity of lithium-ion battery fires.
Locations like New York Metropolis which have been most affected by these fires aren’t glad with this voluntary strategy. Because of this, the New York Metropolis Council simply handed a legislation mandating plenty of USCPSC requirements by August 2023, together with the UL 2849 Normal for Electrical Methods for e-bikes. This laws may result in elevated police scrutiny of already weak supply staff whereas minimizing the quantity low-quality battery packs which have traditionally began fires and primarily displaced residents in low-income areas.
As politicians rush to suggest bans on e-bikes and scrutinize security requirements, contemplating the huge regulatory equipment that covers the automotive business is worth it. Vehicles, and even bikes for that matter, have been round lengthy sufficient that almost each nation has selected a fancy and thorough set of laws to maintain customers and the roads secure. And whereas e-bikes aren’t precisely new, the speed at which e-bikes are evolving and proliferating implies that creating laws is a fluid activity.
An excessive amount of regulation runs the danger of hindering the adoption of such versatile automobiles, whereas too little can result in a tradition of unsafe merchandise and endangered populations. As with the adoption of battery-electric vehicles and the accompanying infrastructure, it appears that evidently regulators and legislators might want to collaborate with producers to create acceptable security requirements along with surveying customers to make sure that use-ability and affordability are saved in thoughts. And earlier than you lose sleep over the considered an electrical automobile fireplace, do not forget that these fires are nonetheless extraordinarily uncommon, whether or not you trip an e-bike or drive a Nissan Leaf.
