With the rapid development of new energy vehicles, battery safety issues are receiving increasing attention. Battery fires not only threaten vehicle safety, but may also endanger life and property. So, in the manufacturing process of new energy vehicles, how can we effectively prevent the risk of battery fires? Let's explore this hot topic together.

Main causes of battery fires

Before we delve into fire prevention measures, let's first understand the main causes of battery fires:

Thermal runaway: The temperature inside the battery is too high, causing the chemical reaction to run away

Short circuit: A short circuit occurs inside or outside the battery

Mechanical damage: The battery is hit or squeezed, causing internal structural damage

Manufacturing defects: Quality problems in the battery production process

Thermal imager: A powerful assistant for battery fire prevention

When it comes to fire prevention, you may think of traditional equipment such as fire extinguishers and fire doors. But in the manufacturing of new energy vehicle batteries, an unexpected "hero" is playing an important role-thermal imagers.

A thermal imager is a device that can detect the temperature distribution on the surface of an object. It can convert infrared radiation emitted by an object into a visible thermal image, allowing us to "see" temperature changes that are imperceptible to the naked eye.

How do thermal imagers help prevent fires?

Production process monitoring

On the battery production line, thermal imagers can monitor the temperature of each battery in real time. If a battery has an abnormal temperature rise, the system will immediately alarm, and the staff can deal with it in time to prevent it from happening.

Quality inspection

Finished batteries need to undergo charge and discharge tests before leaving the factory. Thermal imagers can capture tiny temperature anomalies in this process and help screen out potential problem batteries.

R&D support

In the development of new batteries, thermal imagers can help engineers better understand the temperature changes of batteries under different working conditions, providing an important basis for optimizing the design.

In addition to thermal imagers, what other fire prevention measures are there?

Although thermal imagers play an important role in battery fire prevention, they are not the only means of fire prevention. Let's take a look at some other key measures:

1. Advanced battery management system (BMS)

BMS is like the "brain" of the battery. It can monitor the battery's voltage, current, temperature and other parameters in real time, and take protective measures in time when abnormalities are found, such as cutting off the circuit or starting the cooling system.

2. Application of flame retardant materials

In the design of battery packs, the use of high-performance flame retardant materials can effectively prevent the spread of fire and buy precious time for rescue.

3. Thermal management system optimization

A good thermal management system can ensure that the battery works within the optimal temperature range and reduce the risk of thermal runaway.

4. Strict quality control

From raw material selection to finished product testing, every link needs to be strictly controlled to eliminate quality risks.

Future Outlook: AI+ Thermal Imaging Technology

With the development of artificial intelligence technology, future thermal imaging systems may be more intelligent. It can not only detect temperature anomalies, but also predict potential risks. Imagine that when the AI system predicts that a battery may have problems in the future by analyzing historical data and current status, we can take action before the problem actually occurs. This will bring a qualitative leap in the safety of new energy vehicles!

Conclusion: Safety is the cornerstone of the development of new energy vehicles

Battery safety is undoubtedly an important topic on the road to the development of new energy vehicles. From the application of thermal imagers, to advanced BMS systems, to future AI predictions, we have seen that technology is constantly improving and safety assurance is constantly strengthening. But we must also remember that technology is only a tool, and true safety also requires the responsibility and professionalism of every participant. Only in this way can we jointly promote the healthy development of the new energy vehicle industry and contribute to green travel.
