Electric vehicles have become the preferred means of transportation for thousands of families to take short trips, providing great convenience for travel. Many people will choose electric vehicles first, whether it is a delivery boy or a daily commuter, whether it is shopping for vegetables or picking up children.
While electric vehicles bring convenience to people's travel, the number of electric vehicle fire accidents has increased rapidly in recent years. Many people say this is due to the excessive use of lithium batteries. Some people even propose to ban the use of lithium batteries. The number of electric vehicle fire accidents has increased. We may blame lithium batteries. Professionals tell you the real reason.
Increased number of electric vehicle fire accidents
Since 2024, all provinces and cities have strengthened the safety management of electric vehicles. According to the data of the Fire Department, the number of electric vehicle fires will increase rapidly from 2021 to 2023.
The number of electric vehicle fires will be 14000 in 2021, 18000 in 2022, and 21000 in 2023. Electric vehicle fires will seriously affect people's life and property safety.
According to the data, the vast majority of electric vehicles on fire are equipped with lithium batteries, so many people believe that lithium batteries are the cause of electric vehicle fires. Some netizens even suggested that the use of lithium batteries should be prohibited. In fact, we may have mistaken lithium batteries, and the real cause of electric vehicle fires has finally been found.
Maybe the lithium battery is the wrong one. The insiders tell you the real reason
The lithium battery provides convenience for electric vehicles. Because of its high energy density, the battery is lighter. Because the electrolyte solution of the lithium battery is organic, it is flammable and explosive. Many people think that the ignition of electric vehicles is caused by the lithium battery. In fact, these three points are the real reasons for the ignition of electric vehicles.
Modification behavior of electric vehicles
When users use electric vehicles, they will modify them according to their own needs, such as lifting the speed limit of electric vehicles, installing high-voltage batteries, and even replacing high-power motors.
If the electric vehicle is modified, the original circuit of the electric vehicle will be damaged, or the current pressure will be increased on the circuit. In the process of use, it is very easy to cause a short circuit or a fire on the circuit, which will lead to a fire on the electric vehicle.
Use poor quality lithium battery
Lithium batteries have many advantages, but they also have a disadvantage, that is, the price of raw materials is high, so the price of finished lithium batteries is relatively expensive. Some users will choose cheap low-quality lithium batteries when replacing lithium batteries in order to save costs.
The majority of these low-quality lithium batteries are used second-hand battery cells, or even hand assembled by some small workshops. The materials used are also from the disassembled battery cells of automobile batteries. Such batteries are not tight and durable, and there are great potential safety hazards, which can easily lead to fire in the process of use.
Wrong charging mode
When an electric vehicle catches fire, most of them are in the process of charging, so the wrong charging method of lithium battery will cause an electric vehicle fire.
When charging the electric vehicle, you must choose a matching charger, and do not overcharge. After the green light of the charger is turned on, the power supply should be cut off in time, and when charging, you should choose a cool and ventilated environment, which can effectively reduce the probability of electric vehicle fire.
summary
Many people think that the electric vehicle fire accident is caused by the lithium battery. In fact, this understanding is rather one-sided. The real reasons for the electric vehicle fire are mainly the modification of the electric vehicle, the use of low-quality lithium batteries, and the wrong charging method. As long as these three problems are solved, the lithium battery can still be considered for use.
