Erinome: Hello everyone and welcome back to our show! I'm Erinome.

Enceladus: And I'm Enceladus. Today we have a really interesting topic to talk about.

Erinome: Yes, it's about new energy cars, or EVs. Recently, a story about "poor-quality electricity" has been all over the internet.

Enceladus: That's right. It started when an EV in Shanghai suddenly caught fire. It burned very, very fast.

Erinome: Oh no, that sounds scary. Was anyone hurt?

Enceladus: Luckily, the two people inside the car got out safely. But after this, a strange idea appeared online.

Erinome: What idea?

Enceladus: People started saying the fire was caused by "poor-quality electricity". They called it "lie zhi dian".

Erinome: "Lie zhi dian"? Poor-quality electricity? I have never heard of that before. What does that even mean?

Enceladus: Well, some people on the internet tried to explain it. They said it's electricity that is not "pure".

Erinome: Pure? How can electricity be not pure? Does it have dirt in it? Haha.

Enceladus: Haha, almost! One person joked that it has many "impurities" inside, like some strange metals.

Erinome: Wow, that sounds like something from a science fiction movie, not real life.

Enceladus: Exactly. Others gave a more "scientific" explanation. They said good electricity has a voltage of 220V and a frequency of 50HZ.

Erinome: Okay, that sounds normal.

Enceladus: But they said "poor-quality electricity" has a voltage that is too high or too low, and the frequency is not stable.

Erinome: Um, I see. So it's like the power is not steady?

Enceladus: Yes. And they also said this kind of electricity comes from "irregular" power grids and is usually much cheaper.

Erinome: So it's like a trap? You pay less but you might burn your car?

Enceladus: That's the idea they were spreading. People got really creative with it.

Erinome: Oh? What did they say?

Enceladus: It's very funny. One person said that solar power is bad because it has too much sand in it.

Erinome: Haha! Sand in the electricity! What else?

Enceladus: They said hydropower is bad because it has water grass. Wind power has smog. And nuclear power has wastewater.

Erinome: Oh my goodness. So according to them, there is no good electricity at all!

Enceladus: Haha, yes. Another person joked that maybe electricity has an expiration date, and "lie zhi dian" is just expired electricity.

Erinome: This is getting more and more ridiculous. But you know, it's funny, but did anyone actually believe this?

Enceladus: Sadly, yes. Some people really believed it. That's why this topic became so hot online.

Erinome: So, what's the truth? Is there really such a thing as "poor-quality electricity"?

Enceladus: Well, reporters did some investigation. They called several big EV companies.

Erinome: And what did the car companies say?

Enceladus: Most of them said they had never heard about it. One company's customer service said it very clearly: there is no such thing as "poor-quality electricity".

Erinome: So, it's not real?

Enceladus: They said electricity only has different prices, but not different qualities.

Erinome: Okay, that makes more sense. What about the State Grid, the company that provides the electricity?

Enceladus: They were called too. And their answer was the same. They said "poor-quality electricity" does not exist.

Erinome: So it's officially a rumor.

Enceladus: Yes. They did say that if a charging pile is broken, it can affect how fast your car charges. But the electricity itself is always the same.

Erinome: I understand. In China, the electricity that comes to our homes and charging stations must meet strict national standards, right?

Enceladus: Exactly. There are rules for voltage, frequency, and other things. So the electricity from the grid is always "qualified".

Erinome: So, if it's not the electricity, then why do these cars sometimes catch fire? That's the real question

Enceladus: That's the important part. The experts say we should look at the car itself. The problem is usually with the battery, the charging equipment, or the battery management system.

Erinome: You mean, things like the battery getting too old or damaged?

Enceladus: Yes. Or overcharging, short circuits, very high temperatures, or if the car was in an accident. These are the real reasons

Erinome: That makes sense. But I also read something about "poor-quality charging piles". Is that the same thing?

Enceladus: Oh, that's a very good point. No, it's not the same, but it's related. "Poor-quality electricity" is a rumor, but poor-quality charging piles are a real problem

Erinome: Tell me more about that

Enceladus: Some of these bad charging piles lie about their power. They say they are "fast charging", but they are actually very slow

Erinome: So they trick people

Enceladus: Yes. And what's worse, their voltage is not stable. It can damage the car's battery over time. A good battery that should last 5 years might only last 3 years
