5 new energy vehicle rumors that should be debunked

As environmental regulations become increasingly stringent, the development of new energy vehicles is also getting faster and faster. Compared with fuel vehicles, electric vehicles and other new energy vehicles have lower vehicle costs, and many large cities are seeing more and more new energy vehicles. However, as a relatively new thing, new energy vehicles often have some rumors during use. Let's take a look.

A new car needs to be charged three times to 100%

In the Nokia era, we often followed this "rule of use" when using rechargeable batteries in mobile phones. This is because the nickel-metal hydride batteries used in the past have a "memory effect", and if they are charged before they are fully used, the battery life will be reduced quickly. But nowadays, most vehicles use lithium batteries, which have the advantages of large storage capacity, no memory, and many cycles, so there is no need to wait until the battery is exhausted before charging.

Fast charging destroys the battery

"Charge for two minutes, talk for two hours", fast charging is very popular in today's mobile phone era. When it comes to new energy vehicles, many people think that fast charging will cause more damage to the vehicle battery. In fact, whether it is DC fast charging or AC slow charging, as long as the charging limit is controlled within 1c, that is, fully charged in more than 1 hour, it will not affect the battery life.

New energy vehicles have great radiation

Many people have a question: Will new energy vehicles with such a large battery pack generate a lot of radiation? In fact, it is ionizing radiation, not electromagnetic radiation, that is harmful to the human body. The earth where humans live is itself a large magnetic field. The thermal radiation and lightning on its surface can generate electromagnetic radiation, while ionizing radiation is extremely rare. It is electromagnetic radiation with a wavelength of less than 100nm. The prerequisite for the generation of ionizing radiation is the release of huge energy, and the energy of the battery of new energy vehicles is far from meeting the standard, so there is no need to worry about radiation problems.

Turning on the headlights will consume battery power and reduce mileage

When the car battery is low, many people think that turning off the headlights will save some power. But in fact, the power supply for the lights and audio is a separate 12V lead-acid battery, which is the battery on the traditional vehicle, not the battery pack of the drive system. So the two are actually independent of each other.

Cannot charge in rainy days

Unlike household appliances, the charging port of a car is designed strictly in accordance with the IP54 protection standard, and all vehicles must simulate the rainy environment before leaving the factory. So in daily life, if you need to charge in the rain, you don’t have to worry too much, but if it is a thunderstorm, you should be a little careful.
