Lithium-ion batteries pose too high of a fire danger

The Hidden Dangers of Uncertified E-bike Batteries

As a retired supervising fire marshal of the New York City Fire Department’s Lithium-Ion Task Force, I have firsthand experience with the devastating consequences of lithium-ion battery fires. While city efforts to educate the public have made progress,the dangers remain,especially when it comes to micromobility devices used on public transit.

The Threat of thermal Runaway

One of the most notable dangers posed by uncertified e-bike batteries is their susceptibility to thermal runaway. This is a perilous chain reaction that occurs when a battery cell overheats, causing adjacent cells to overheat as well. The heat generated can lead to combustion adn explosions, creating a serious fire hazard.

Uncertified Batteries Increase the Risk

Uncertified batteries often lack the necessary safety features and quality control measures found in certified batteries.They may contain defective cells,improper wiring,or insufficient insulation,all of which can increase the risk of thermal runaway and fire.

A Need for Safety Standards

To address these risks, there is a growing need for stricter safety standards for e-bike batteries. These standards should cover not onyl the battery’s construction and design but also it’s charging and usage practices.

Legislative Efforts Stumble

While there have been efforts to establish safety regulations for e-bike batteries, progress has been slow. Some lawmakers argue that regulations could stifle innovation, while others point to the potential economic impact of recalls and safety investigations.

Local Laws Face Challenges

Local governments are also grappling with the challenge of enforcing e-bike battery safety regulations. Many cities lack the resources and expertise to effectively inspect and test batteries, leaving consumers vulnerable to potentially dangerous products.

The Urgency of Action

The urgency of addressing this issue cannot be overstated. Lithium-ion battery fires are becoming increasingly common, and the consequences can be devastating. In a crowded subway car, a battery fire could result in widespread injuries or even fatalities.

A Call to Action

Consumers need to be aware of the dangers of uncertified e-bike batteries. When purchasing an e-bike, it’s crucial to ensure that the battery is certified by a reputable organization, such as UL or CE. Riders should also follow all safety recommendations provided by the manufacturer.

Lawmakers, regulators, and industry leaders must work together to establish and enforce complete safety standards for e-bike batteries. Public awareness campaigns can play a vital role in educating consumers about the risks and encouraging them to choose safe products.

By taking proactive steps, we can mitigate the risks posed by lithium-ion battery fires and ensure the safety of everyone who uses e-bikes and other micromobility devices.

The Hidden Danger of Lithium-Ion Batteries

Lithium-ion batteries power our world,from smartphones to electric vehicles. However, these ubiquitous energy sources come with a hidden danger: thermal runaway, a dangerous chain reaction that can lead to intense fires.

Uncertified Batteries: A Fire Hazard

Uncertified lithium-ion batteries are notably susceptible to thermal runaway.A 2023 study by Soteria Battery Innovation Group revealed alarming statistics about e-bike usage in the U.S. The study found that 33% of e-bike deliveries experienced fires and 22% of “Offroad & touring” riders reported fires. The research indicates a concerning trend linked to user practices, with 71% of both groups conducting their own maintenance and a significant percentage using refurbished batteries.

The Urgent Need for Safety Standards

Soteria’s research underscored the critical need for standardized safety protocols for e-bike batteries. Their proposed standards include the use of certified cells, proper cell spacing, busbar requirements, and enhanced battery management systems (BMS). This initiative has garnered support from 20 companies,highlighting the industry’s recognition of the issue.

Legislative Gaps and Local Challenges

Despite growing awareness of the risks, national legislation mandating safety standards for lithium-ion batteries has stalled. While H.R.1797, the Setting Consumer Standards for Lithium-ion Batteries Act, passed the U.S. House with bipartisan support in 2023, it failed to be adopted by Congress in 2024.

On a local level, New York City implemented local Law 39 of 2023, requiring e-bike, e-scooter, and lithium-ion battery certification to North American UL Standards. However,a subsequent state law allowing EU Standard certification has created confusion. Furthermore, owning uncertified products is not illegal in the state. This highlights the urgent need for stronger federal regulations to ensure consistent and effective safety measures.

The Firestorm: Numbers Don’t Lie

The FDNY reported 279 lithium-ion battery fires in 2024, with two-thirds attributed to micromobility devices. Importantly, over 50% of these fires occurred when the battery was not charging, emphasizing the need for careful handling and storage at all times.

A Call to Action: Protecting Our communities

The safety of our communities depends on swift and decisive action. We must demand stricter regulations, promote industry-wide adoption of safety standards, and educate consumers about the risks associated with uncertified lithium-ion batteries. As Bosch and Propel, leaders in certified e-bike products, stated, “We need laws in place to protect the public.” By working together, we can create a safer future for everyone.

The Increasing Danger of Lithium-Ion Battery Fires

While the number of fatalities directly linked to lithium-ion battery fires has dipped from 18 in 2023 to six in 2024, the threat posed by these fires remains significant. The wildfire-like smoke they generate is particularly hazardous, containing significantly higher levels of carbon monoxide and carbon dioxide compared to traditional fires. These toxic gases pose a rapid and severe threat, increasing the risk of fire-related deaths.

enforcing Safety Standards

To combat this growing danger, the FDNY’s Lithium-Ion Task force, in collaboration with the Department of Consumer and Worker Protection, is actively enforcing stricter safety standards, particularly the North American UL Standard, aimed at minimizing the risk of lithium-ion battery fires. However,challenges persist. FDNY Commissioner Daniel Nigro recently expressed concern over businesses attempting to circumvent safety checks by relocating operations.

A Global Concern

The issue transcends New York City’s borders. In 2023, London’s Fire Brigade reported 279 lithium-ion battery fires, with two-thirds linked to micromobility devices. similarly, Australia’s New South Wales Fire and Rescue recorded 285 such fires.

Mitigation and Protection

“The IDLH (Immediate Danger to Life & Health) atmosphere is 10 to 20 times greater in confined spaces,like subway cars,” experts at Soteria’s third annual LithiumSAFE: Battery Safety workshop in Greenville,South Carolina,emphasized,highlighting the amplified risk in these environments. Public awareness, stricter regulations, and enhanced fire safety protocols are crucial to mitigating the dangers posed by lithium-ion battery fires.

Consumer Responsibility

Individuals can prioritize battery safety by diligently following these practices: using approved chargers, avoiding overcharging, and inspecting batteries for any signs of damage. These simple precautions can significantly reduce the risk of fire.

Addressing E-Scooter and E-Bike Fires on Public Transit

The increasing number of lithium-ion battery-powered e-scooters and e-bikes catching fire on public transportation systems has raised serious safety concerns. While London and Toronto have implemented bans on privately owned e-scooters and e-bikes on public transit, these reactive measures fall short of addressing the underlying issues. In November 2021, a lithium-ion battery e-scooter erupted on a london train, spreading to the platform at Parsons Green station, prompting transport for London (TfL) to ban privately owned e-scooters and e-unicycles from its transport network in December 2021.

Toronto also faced a similar incident when an e-bike exploded on a subway car on New Year’s Eve 2023, resulting in two individuals being hospitalized. Toronto Fire Services identified water intrusion at the battery’s USB charging port as the probable cause. As a precautionary measure, the Toronto Transit Commission (TTC) banned e-bikes and other lithium-ion battery-powered mobility devices during the winter months in December 2024.

Looking Ahead

The dangers posed by lithium-ion battery fires necessitate a multifaceted approach involving rigorous safety standards, proactive prevention measures, and informed public awareness. By prioritizing safety and embracing responsible battery practices, we can mitigate the risks associated with these increasingly common incidents and safeguard our communities.
