As electric vehicles (EVs) become more popular, more people are enjoying the convenience and environmental benefits they offer. However, occasional incidents of EV fires have raised concerns. What causes these fires, and how can we prevent them? Let’s explore.

Causes of EV Fires

1. Battery Overheating

The battery is the power source of an EV, and its safety directly impacts the vehicle’s overall safety. If the battery gets too hot, it can lead to thermal runaway and eventually cause a fire. Overheating can result from prolonged charging, poor-quality charging equipment, or long-term exposure to high temperatures.

2. Battery Malfunctions

Minor defects in the battery manufacturing process, such as internal short circuits or damaged separators, can trigger fires. Additionally, as batteries age, their performance declines, increasing the risk of malfunctions.

3. Vehicle Collisions

In a collision, the battery can suffer physical damage, such as being crushed, punctured, or deformed. Damage to the battery can lead to short circuits or thermal runaway, causing a fire.

4. Improper Charging

Improper charging practices can also pose safety risks. Using low-quality chargers or charging in high temperatures can cause the battery to overheat. Frequent fast charging or overcharging can accelerate battery aging, increasing the risk of fires.

5. Environmental Factors

Batteries are sensitive to environmental conditions, especially temperature and humidity. Long-term exposure to high temperatures or humidity can affect battery performance and safety, increasing the likelihood of fires.

6. Flammable Items in the Car

Common items like lighters and perfumes can cause fires if left in a hot car for too long. These items release flammable gases at high temperatures and can even explode, leading to vehicle fires. It’s best to avoid leaving such items in the car during hot weather.

To protect your vehicle and prevent high temperatures inside, use car covers and sun shades. These products can block direct sunlight, reduce the interior temperature, and lower the risk of fires.

How to Reduce the Risk of EV Fires

1. Choose High-Quality Batteries and Equipment

When buying an EV, choose brands and models that have undergone rigorous testing and certification. Use manufacturer-recommended chargers and equipment to ensure battery stability during charging.

2. Regular Inspection and Maintenance

Regularly inspect the battery system, especially if you notice abnormal charging or high battery temperatures. Replace aging batteries and components with potential defects promptly to prevent fires.

3. Mind Your Charging Habits

Charge in cool, dry environments and avoid prolonged charging in high temperatures. While fast charging is convenient, it can strain the battery over time, so slow charging is recommended. Follow the manufacturer’s charging guidelines to avoid overcharging.

4. Drive Safely

Avoid aggressive driving to reduce the risk of collisions. If your vehicle has been in a significant impact, especially if the chassis is damaged, get a professional inspection to ensure the battery is intact.

5. Good Parking Habits

Park in cool, dry places and avoid long-term exposure to high temperatures or humidity. If possible, install an onboard temperature monitoring device to keep track of the battery’s temperature.

Electric vehicles are a key part of future transportation. Despite some safety concerns, these risks can be minimized with proper preventive measures. Understanding how your vehicle works and maintaining good habits are essential for every EV owner. This way, you can fully enjoy the green travel experience that EVs offer.
