Electric scooters are becoming an increasingly common sight on streets and pavements. However, their lithium-ion batteries can be vulnerable to variations in temperature and tend to degrade when exposed to very hot or cold environments. If these batteries are damaged, charged incorrectly, or left unattended, they can overheat, release flammable gases, and ignite in a process called 'thermal runaway'. While there is no national data on how often electric scooters catch fire, the New York City Fire Department reported more than 130 such fires in 2022, with six deaths. Similarly, the London Fire Brigade reports seeing a growing number of fires caused by electric scooters, with one occurring roughly every two days.

What You'll Learn
Electric scooter battery fires are not common
The National Fire Protection Association (NFPA) has warned that these batteries can overheat, catch fire, and cause explosions, but there is no national data on the frequency of these incidents. The NFPA notes that the New York City Fire Department reported more than 130 fires in 2022, a significant increase from the 13 fires reported in 2019 when they started tracking e-bike fires. From 2019 to 2022, there was a over 600% increase in fires started by e-bikes and e-scooters, resulting in five deaths and dozens of injuries.
The London Fire Brigade also reported a growing number of fires caused by e-scooters, with incidents occurring roughly every two days. Similarly, Zurich Insurance data showed a 149% increase in fires caused by e-scooters and e-bikes from 2020 to 2022. These fires can be costly, with claims ranging from £6,000 to £84,000.
While the risk of fire is present, it is important to follow safety precautions to minimize the chances of an incident. This includes using only the battery and charger designed for the specific e-scooter, charging at the recommended temperature range of 32°F to 105°F (0°C to 43°C), and discontinuing use if the battery emits smoke, an unusual odor, or becomes hot. Most electric scooters are also equipped with Battery Management Systems to prevent lithium battery fires.

How to prevent electric scooter fires
Electric scooter fires are rare, but they can happen. Most electric scooter fires result from lithium-ion battery failures. These batteries are the same type used in cars, phones, and computers. If you use or store them improperly, they can pose a fire risk.
- Always follow the manufacturer's instructions and safety precautions when using, charging, and storing your electric scooter.
- Check your batteries regularly for any signs of wear and tear. If you notice any damage, stop using the battery and replace it.
- Do not overcharge your batteries. Only recharge them for the amount of time specified by the manufacturer.
- Never leave your electric scooter unattended while it is charging. Unplug the scooter once it is fully charged.
- Store your electric scooter away from flammable materials, such as paper, fabric, and vinyl wood.
- Only buy electric scooters and replacement parts from reputable manufacturers and dealers. Ensure that your scooter has the CE marking, indicating compliance with European safety standards.
- Use only the charger specified by the manufacturer for your specific battery type.
- Keep batteries at room temperature and allow them to cool down before charging.
- If your battery is swollen or making strange noises, isolate it immediately.

Why electric scooters catch fire
Electric scooters have gained popularity due to their convenience and relatively low cost. However, they have gained attention for battery fires. Electric scooter batteries contain highly flammable materials, which can ignite under certain conditions. While these fires are not particularly common, they can have devastating consequences.
Lithium-ion batteries, which are commonly used in electric scooters, are vulnerable to temperature variations. Exposure to extreme heat or cold can cause the battery to fail and become volatile. This is because the chemical reactions inside the battery cell produce heat, and this heat accelerates the subsequent chemical reactions, leading to a rapid increase in temperature. This process is known as "thermal runaway," which can result in the release of flammable gases and ignition.
Improper use and storage of lithium-ion batteries can also increase the risk of fires. Overcharging, using the wrong charger, or exposing the battery to water and other liquids can cause corrosion or damage to the internal components, increasing the likelihood of a fire. Additionally, mechanical damage, such as dropping or puncturing the battery, can lead to internal short circuits and potential ignition.
To prevent electric scooter battery fires, it is crucial to follow the manufacturer's instructions and safety precautions. Regularly inspect the battery for any signs of damage, such as cracks, dents, or leaks. Avoid exposing the battery to extreme temperatures and always charge it within the recommended operating temperature range. Only purchase scooters and batteries from reputable dealers and manufacturers who comply with safety standards.
By following these precautions and staying informed about the potential risks, electric scooter users can significantly reduce the chances of battery fires and ensure a safer riding experience.

The rise in electric scooter fires
Electric scooters are becoming an increasingly common sight on our streets and pavements. However, the rise in their popularity has also led to a rise in fires caused by these scooters. This trend is not just limited to electric scooters but also includes other products that use lithium-ion batteries, such as e-bikes, mobile phones, laptops, and drones.
The lithium-ion batteries that power these scooters can overheat, catch fire, and even cause explosions if they are damaged, charged incorrectly, or left unattended. Data from Zurich Insurance reveals a 149% increase in fires caused by e-scooters and e-bikes, from 67 in 2020 to 167 in 2022. The London Fire Brigade reports a similar trend, with an e-scooter fire occurring roughly every two days in London.
To address this issue, fire safety researchers are investigating ways to prevent and mitigate the spread of these fires. The National Fire Protection Association has also published a safety tip sheet to help prevent injuries and deaths related to e-scooter fires. It is important for users to follow manufacturer instructions and safety precautions and use only reputable dealers and manufacturers to reduce the risk of electric scooter fires.

The dangers of counterfeit electric scooter batteries
Electric scooters have become a common sight in cities, with their popularity soaring in recent years. However, concerns have been raised about the safety of these devices, particularly regarding battery fires. While lithium-ion batteries power many devices, they can pose a fire risk if not used, charged, or stored correctly. This risk is not limited to electric scooters but also includes other devices such as mobile phones, laptops, and power tools.
The issue of electric scooter battery fires is a growing problem. Data from Zurich Insurance reveals a 149% increase in fires caused by e-scooters and e-bikes from 2020 to 2022. The London Fire Brigade reports a similar trend, with an average of one fire every two days in 2023 attributed to e-scooters and e-bikes. These fires can have devastating consequences, resulting in injuries and even deaths.
One of the contributing factors to these fires is the use of counterfeit or cheap batteries. Consumers may be tempted to purchase these batteries due to their lower cost, but they often do not meet the same safety standards as authentic batteries. Counterfeit batteries may use lower-quality materials that are more susceptible to overheating and fire. They may also lack the necessary safety features and protections found in reputable batteries.
To make matters worse, some consumers may not be aware that they have purchased a counterfeit battery. These batteries can be bought online and may look identical to genuine batteries, making it difficult for consumers to distinguish between them. As a result, they may unknowingly put themselves at risk by using these unsafe products.
To avoid the dangers of counterfeit electric scooter batteries, it is crucial to only purchase from reputable dealers and manufacturers. Consumers should look for the CE marking, indicating compliance with European safety standards. Additionally, following the manufacturer's instructions for use, charging, and storage is essential to minimize the risk of battery fires. Regularly checking batteries for any signs of wear and tear and proper disposal when they reach the end of their life are also important safety measures. By being vigilant and informed, consumers can help protect themselves and others from the potential hazards of electric scooter battery fires.
