Electric cars and accidents: all you need to know

Often we read alarming news about electric cars and the supposed serious dangers to which drivers are exposed in an accident.

If there are no doubts about the advantages of electric cars in points such as: less environmental impact, positive consequences for health and the lower cost of mobility, the point of safety is not yet sufficiently explored.

In all areas, the lack of knowledge generates fears. This also happens with electric cars: false myths and unfounded fears have been created related to the greatest danger of electric cars, which are not considered safe enough in the (unfortunate) case of accident.

Let’s look at these false myths in detail, one by one.


Probability of fire

Electric and hybrid cars, such as traditional gasoline or diesel, are designed to minimize the risk of fire. Renault, which has been working with fully electric cars for years, has a department dedicated to the safety of these vehicles. The same thing happens with the main automobile manufacturers that are dedicated to electric cars. However, some elements must be specified. There is the concept of primary security, which is related to the vehicle in motion, and secondary security, which refers to the protection of the occupants. But there is also tertiary security: that which is related to the intervention of emergency workers. In case of fire, which could be caused by external factors, the only way to extinguish a lithium battery is to flood it with water. For this, the “fireman’s access” is present in electric cars, a hole in the body in which the fire hose is placed to flood the batteries.



The batteries

Sometimes drivers have doubts about the safety of electric car batteries. Manufacturers work on the safety of accumulators throughout their life cycle, from construction to recycling, and also installation. Analyze the cycles of loading and unloading, maintenance and repair. Nothing is left to chance.

Many individual components of electric cars, including batteries, have their own protection systems. However, as if this were not enough, for a greater guarantee of passive safety, the batteries are integrated into the car’s system.


Preliminary tests

Car manufacturers study the correct position of the batteries in the design phase with different tests. The batteries are required to overload, excessive discharge, recharge after an overload, external electric shock. The cell is exposed to an internal electric shock, overheating, thermal propagation, fire and low temperatures. Finally, the entire car is exposed to crash tests, penetration, impact and vibration tests. Like cars with gasoline engines, only if the car passes all these tests is validated.


Therefore, the safety of electric cars is comparable, if not even higher, than that of traditional cars. False myths and rumors should not stop a growing market, which is good for the environment.
