In a startling incident in China, a lithium EV battery mishap turned an elevator into a magnetic field, resulting in a severe accident. The incident, captured on video, shows the dangers of carrying large rechargeable batteries in confined spaces like elevators.
This blog explores the incident, its causes, and the lessons learned to ensure safety with EV batteries.
The Incident
The alarming event took place when a man carried a fully charged EV battery into an elevator. As the elevator doors closed, the battery’s electro-charge interacted with the metal body of the lift, creating a powerful magnetic field.
This interaction resulted in a thunderbolt effect, causing the battery to explode.
Captured on Video
A video circulating online shows the terrifying moment the battery exploded. The footage begins with the man entering the elevator with the battery. As soon as the doors close, the battery starts to emit sparks and then explodes.
Smoke quickly fills the lift, and the man is left unconscious and injured. Panic spreads outside the elevator as bystanders react to the smoke and the injured man. Security personnel eventually drag him out, showcasing the severe consequences of the mishap.
Understanding the Cause
The primary cause of the incident was the static charge accumulated by the fully charged EV battery. When the elevator doors closed, the battery’s charge interacted with the metal body of the lift, creating a magnetic field.
This phenomenon led to a thunderbolt effect, causing the battery to explode violently. Such incidents highlight the risks associated with carrying large rechargeable batteries in small, metallic spaces.
Science Behind the Incident
Lithium-ion batteries, commonly used in e-bikes and other EVs, store and release large amounts of electrical energy. When a battery is fully charged, it can accumulate static electricity on its surface.
In confined spaces like elevators, the metal walls can act as conductors, allowing the static charge to build up to dangerous levels.
When the battery’s electro-charge interacts with the metal body of the lift, it can create a magnetic field. This is due to the movement of charged particles within the battery, generating an electric current that produces a magnetic field.
The sudden discharge of the accumulated static charge through the metal structure can result in a spark or even an explosion, similar to a thunderbolt effect. This rapid discharge of energy is what caused the battery to explode in the confined space of the elevator.
Similar Risks with EVs
This incident isn’t an isolated risk. EVs parked near earthing structures like electric poles, steel gates, or even other cars can pose similar dangers. The electro-charge of the batteries can create hazardous situations if they come into close contact with metal surfaces, leading to explosions or fires.
Safety Precautions
To prevent such accidents, it’s crucial to follow safety precautions when handling EV battery:
- Avoid carrying large batteries in confined spaces
Confined spaces like elevators can turn hazardous when large batteries are present.
- Proper earthing
Ensure that EVs and their batteries are properly earthed to avoid static charge buildup.
- Regular maintenance
Regularly check and maintain your EV battery to ensure it is in good condition and free from defects.
- Awareness and training
Educate users about the potential risks and safety measures associated with handling EV batteries.
The Aftermath
The man involved in the incident suffered serious injuries and was rendered unconscious due to the explosion. The video showing the aftermath, with the man being dragged out of the lift by security personnel, underscores the severity of the situation.
This incident serves as an evident reminder of the potential danger associated with EV battery and the importance of following safety protocols.
The EV battery mishap in China is a wake-up call for all EV users and manufacturers. Ensuring the safety of rechargeable batteries, especially in confined spaces, is most important.
This incident highlights the need for increased awareness and strict safety measures to prevent such accidents in the future. As the popularity of EVs continues to rise, prioritizing safety will be crucial to avoid similar incidents and protect users from harm.
