Why are electric cars better than gasoline cars?

The image of electric cars running through flooded roads while internal combustion engine cars stand in battle can make many people question why electric cars have such superior capabilities. The reason comes from the characteristic difference between the two sides.

Gasoline or diesel cars have many mechanical details, with parts that are “sensitive” to water such as air intakes and exhaust pipes. When water through these open necks enters the engine, it will cause stalling, bending, and broken arm, causing great losses. One of the most serious damage when a vehicle is submerged in water is a water attack – a severe form of damage to the internal combustion engine. And engine repair is also a leading expense when using a car.

Meanwhile, electric cars have no engine but use an electric motor – a device with a simpler structure than an internal combustion engine. Both the motor and the battery block are in a sealed box so they are not affected by water. The battery block is also insulated from the rest of the vehicle.

Electric vehicles typically have an IP65 or IP67 ingress protection system, depending on the vehicle type. IP (Ingress Protection) represents protection from two elements: dust and water. The higher the index, the better the resistance to dust and water. Modern electric vehicles typically have an IP67 rating, which allows them to be submerged in water up to one meter high for up to 30 minutes without leakage.

For example, information on VinFast’s website shows that its electric car model is the e34 with IP67 protection level. Accordingly, the car is capable of withstanding water up to a meter deep for about 30 minutes.

However, it is not possible to be subjective when driving an electric vehicle, because an electric vehicle is not a boat, which means it is not designed to swim. Drivers are always advised not to drive through flooded areas for a variety of reasons, especially when the water level can rise further, rendering the vehicle immobile, even being swept away, and the occupants of the vehicle. dangerous to life. In addition, it is difficult to determine the depth of the flooded area, so it is impossible to be sure whether the water level is within the safe limits of the vehicle.
