This pie chart shows the lithium-ion battery incident reporting statistics, out of which there are approximately 15,621 incidents involving fire over all the years.

 

Here are the main risks operators should watch out for:

 

• Overcharging and Overvoltage: Charging a battery beyond its recommended voltage can cause overheating. This often results from a failed Battery Management System (BMS) or a charger that doesn’t shut off on time.

 

• Physical Damage to Batteries: Shared vehicles endure daily wear and tear, and damage, such as dents, cracks, or punctures, can expose internal components. This raises the risk of leaks, short circuits, or fires.

 

• Faulty or Misconfigured Battery Management Systems: A BMS monitors battery charge, temperature, and health. If it’s misconfigured or poorly maintained, it may miss warning signs such as overheating or cell imbalance.

 

• Charging in Unsafe Environments: Charging in hot, enclosed, or poorly ventilated areas can trap heat and stress the battery, increasing fire risk.

 

• Aging or Degraded Batteries: As batteries age, they lose capacity and become more prone to short circuits and thermal issues.

 

• Charging Batteries Too Close Together: Charging batteries without proper spacing can cause localized heat buildup, especially if one of the batteries is compromised. In worst-case scenarios, this can trigger thermal runaway across multiple units.

 

While these batteries are efficient and widely used, they also carry serious fire risks, especially in dense urban settings. For instance, the FDNY reported 268 lithium-ion battery fires in 2023, causing 18 deaths and 150 injuries across New York City.

 

Even with improved safety education and inspections, incidents remain high: 277 such fires were recorded in 2024, although fatalities dropped to 6 due to proactive outreach.

 

These figures show how micro-mobility fleets, especially in urban and transit-heavy areas, must implement rigorous charging, storage, and inspection protocols to keep both riders and communities safe.

 

Understanding these fire risks is only the first step. Now, it’s about knowing how to prevent them, especially when managing large-scale shared fleets.

 

 

 

 

How to Prevent Micro Mobility Device Lithium Battery Fires and Overheating?

 

Fires and overheating incidents don’t just put vehicles at risk; they can interrupt service, endanger users, and hurt your bottom line. The good news is that many of these risks are preventable with the right systems and habits in place.

 

Here are key strategies fleet operators can follow to keep lithium-ion batteries safe, stable, and efficient:

 

Optimize Charging Protocols to Prevent Overheating

 

Use chargers with built-in temperature sensors and auto shut-off features to prevent overcharging. When possible, opt for slower charging methods to reduce stress on batteries and limit heat buildup.

 

A study showed temperatures reached 350 °C in under 750 seconds in poorly ventilated setups during high-rate charging. So, always place charging setups in well-ventilated areas to allow natural heat dissipation.

 

Here’s a table showing safe vs. unsafe charging practices:

 

Safe vs Risky Battery Charging Practices

Practice	Safe Approach	Risky Approach
Charger Type	Certified smart charger with auto shut-off	Third-party or uncertified chargers
Charging Area	Well-ventilated, cool, monitored	Enclosed, hot, or unattended space
Battery Spacing	Batteries are kept apart to prevent thermal buildup	Batteries stacked or bunched together
Charging Window	Between 20–80% charge	Full charge overnight or deep discharge

Monitor Battery Health with a Reliable BMS

 

A Battery Management System (BMS) monitors charge, voltage, and heat in real time. A well-calibrated BMS monitors voltage, current, temperature, and overall battery health in real-time. Ensure each battery in your fleet is equipped with a reliable BMS, and connect these systems to a centralized dashboard for full visibility.

 

A connected dashboard can show alerts like ‘Voltage Drop in Cell 3’ or ‘Temperature Spike Detected’. This allows you to detect issues like temperature spikes, cell imbalances, or performance drops early before they escalate into operational problems.

 

Stick to a Regular Maintenance

 

Lithium-ion batteries naturally degrade with use, increasing the risk of thermal failure. That’s why monthly inspections are essential to catch visible signs of wear, like swelling, cracks, or leaks.

 

To prolong battery life, avoid full charges or deep discharges. Instead, use partial charging cycles and perform cell balancing to keep voltage levels consistent across cells.

 

Preventing battery fires isn’t just about systems. It’s also about what your ground teams do every day to keep operations safe and running smoothly.

What to Do if a Battery Overheats or Catches Fire in Your Fleet?

 

 

 

 

In high-volume fleet operations, where dozens or even hundreds of batteries are charged, swapped, and transported daily, the chances of overheating or fire incidents increase. That’s why it’s critical to have clear, well-rehearsed emergency protocols in place.

 

Here are the key steps every mobility operator should follow when responding to a lithium battery overheating or fire event:

 

Evacuate and Isolate the Area Immediately

 

At the first sign of overheating or smoke, prioritize safety by evacuating everyone in the vicinity. Lithium battery incidents can escalate fast, so move staff, vehicles, and bystanders to a safe distance.

 

Ensure evacuation routes are clearly marked and exits remain accessible. In indoor settings like warehouses or charging stations, activate fire doors or containment systems to isolate the hazard and limit further exposure.

 

Use the Correct Type of Fire Extinguisher

 

Not all extinguishers are suitable for battery fires. The preferred option is a Class D fire extinguisher, specifically made for combustible metals like lithium.

 

If flames appear, evacuate the area and use a Class D extinguisher with a sweeping motion to smother the fire. If unavailable, isolate the fire by shutting off power sources and using dry sand as a backup containment method.

 

Cool the Battery, If Conditions Are Safe

 

If the battery is overheating but hasn’t ignited, quick cooling may prevent ignition. If it’s safe, move the unit to a well-ventilated area away from flammable materials.

 

Use a misting spray or an air-based cooling system to lower the temperature. Never apply water directly to a burning lithium battery, as it can cause dangerous chemical reactions.

 

Contain the Incident to Prevent Spread

 

Once evacuation and initial response are complete, focus on containment. Relocate nearby batteries, vehicles, or combustible materials away from the affected area.

 

Use fire-resistant barriers or containment boxes if available. Indoors, turn off HVAC systems to prevent the spread of smoke and fumes, which can delay emergency response and endanger health.

 

Continue Monitoring After the Fire

 

Lithium batteries can reignite due to thermal runaway, even after the fire appears out. Use thermal cameras or temperature sensors to monitor the affected area for several hours. Watch for residual heat, smoke, or smoldering, and keep staff on-site during this period. Document any abnormal activity for follow-up.

 

Report the Incident and Maintain Documentation

 

Create a detailed incident report including the time, location, battery type, actions taken, personnel involved, and suspected causes. Maintain this documentation for regulatory compliance, insurance, and internal reviews. Also, share findings with relevant teams to support ongoing safety improvements.

 

Debrief Staff and Update Safety Protocols

 

Hold a structured debrief session post-incident. Review what happened, assess what worked well, and identify areas for improvement. Use insights to update training, revise emergency checklists, enhance signage, and strengthen your overall response plan. Treat each incident as a learning opportunity to boost team readiness and resilience.

 

Having a clear emergency response plan is only part of the equation. Staying compliant with U.S. safety standards is also important to protect your fleet and avoid regulatory trouble.
