Did the new energy vehicle catch fire because it was charged with "inferior electricity"? Don't believe everything.

Recently, an incident where a new energy vehicle in Shanghai caught fire without any apparent reason has drawn public attention. While netizens are curious about the cause of the fire, there has also been a rumor circulating online that the vehicle caught fire because it was charged with "poor - quality electricity".

I've never heard the term "poor - quality electricity" before. At first, I thought netizens were just joking around. But after watching a few videos, I found that some people actually believe in the existence of "poor - quality electricity", and there are even people who specifically introduced the concept of it.

Differentiating "good and poor - quality electricity" by voltage, "none of hydro, nuclear, wind, and thermal power is good enough"

Some netizens claim that "poor - quality electricity is unrefined electricity with a lot of impurities, such as thulium, radium, rhodium, and moscovium."

Some netizens also "popularize knowledge" that there is a distinction between "good - quality electricity" and "poor - quality electricity".

"Good - quality electricity" has a voltage of 220V, a power frequency of 50HZ, and a sine - wave waveform distortion. While electricity with a voltage less than 192V or greater than 242V, a power frequency deviating from 50 ± 0.2HZ, and a large number of oblique waves in waveform distortion belongs to "poor - quality electricity".

There are even videos claiming that "poor - quality electricity refers to electricity with unstable voltage, a lot of impurities, or from unregulated sources, that is, electricity transmitted through unregulated power grid channels."

The video also claims that "charging with this kind of poor - quality electricity for a long time can cause serious hazards such as fires and equipment damage, and this kind of electricity is generally much cheaper than that at ordinary charging stations."

In response to the statement of "poor - quality electricity", some netizens started to make jokes.

Some netizens joked that "poor - quality electricity is the electricity struck by thunder."

Some other netizens teased, "Photovoltaic power can't be used, it has too much sand! Hydro power can't be used, it has too many waterweeds! Nuclear power can't be used, it has too much wastewater! Wind power can't be used, it has too much smog! Thermal power can't be used, it has too many impurities! Good - quality electricity is really scarce, so charge it while you can and cherish it."

The official says there is no such thing as "poor - quality electricity"

For a while, there were all kinds of strange statements about "poor - quality electricity".

In response, I specifically consulted several leading new energy vehicle manufacturers and the State Grid to find out if the statement of "poor - quality electricity" is true.

A customer service representative from Automobile Manufacturer 1 said that they haven't received any information about "poor - quality electricity" for the time being;

A customer service representative from Automobile Manufacturer 2 also said that the information about "poor - quality electricity" is not clear;

A customer service representative from Automobile Manufacturer 3 told me that there is no such thing as "poor - quality electricity", and it simply doesn't exist;

While denying the existence of "poor - quality electricity", a customer service representative from Automobile Manufacturer 4 also said that electricity only differs in price, not in quality.

In addition to calling the customer service, I also searched for information about "poor - quality electricity" on the official accounts of these new energy vehicle manufacturers, and the results were all "no such content available".

Meanwhile, a customer service staff member from the State Grid also told me that there is no such thing as "poor - quality electricity". If the charging pile or circuit is damaged, it will indeed affect the charging efficiency, but the electricity charged is the same.

Behind the rumor is the concern about safety issues, but we should also think rationally

The reason why the statement of "poor - quality electricity" has spread widely is essentially due to consumers' concern about the safety issues of new energy vehicles.

But it is believed that with the development of technology, the safety issues of new energy vehicles will be better guaranteed.

Therefore, when facing rumors, we should think rationally. Without investigation, there is no right to speak. Any information should be based on the official and authoritative explanations, and we should not believe or spread rumors.
