Lifting a 1-yuan coin and throwing it into the "rocking car" is something that two or three-year-old children are happy to imitate and try. No one expected that in the eyes of 3-year-old girl Tongtong (pseudonym), the battery socket on the electric car was so similar to the coin slot of her favorite "rocking car". When she raised her little hand and threw the coin into the socket, her right hand was burned by the current and the coins were burned off.
Girl was burned due to short circuit in socket
"I saw sparks coming out, so I ran over and saw that the baby's right hand was burnt!" Recalling what happened at that time, Tongtong's grandmother still has lingering fears and can't explain what happened at that time.
Tongtong lives in Dadukou. The day before yesterday, the weather was nice. Grandma took Tongtong to bask in the sun in the yard. She was very happy watching her granddaughter doing things.
When 3-year-old Tongtong was curious about everything, the electric car (similar to a rechargeable motorcycle) parked in the corner of the yard caught her attention. The electric car was parked in the yard by a relative and was being charged. Tongtong walked over and looked at it. Later, he found a coin from nowhere and stuffed it into the socket of the electric car battery.
The grandma heard her granddaughter crying and ran over quickly. The scene before her frightened her. Her granddaughter's right hand was black and burned. Later, everyone found a 1 yuan coin in the plug, which had also been burned.
Tongtong was then sent to the Children's Hospital of Chongqing Medical University by his mother. Professor Tian Xiaofei, director of the Department of Burns and Plastic Surgery, said that this is the second child with electric burns admitted to the hospital in the past week. Fortunately, Tongtong's right hand was only burned, a third-degree electric shock injury, and other parts of his body were not seriously injured for the time being.
What the hell is going on? Tongtong was obviously frightened by all this, and she told her grandma, "The rocking car, I want to go ride the rocking car!"
It turns out that Tongtong often rides on the "rocking car" and is very familiar with the rules for inserting coins in the "rocking car". When he saw the charging socket on the electric car, he regarded it as the coin slot of the "rocking car".
Inserting a coin instantly causes a short circuit
However, some non-standardized electric vehicles still use lead-acid batteries due to price reasons. Similar to traditional batteries connected in series, the "electricity" is stored first after charging and released directly during use. The electric vehicle battery itself is a large-capacity power source, and its charging jack is the same as the socket used at home.
The safe voltage of the human body is 36V. If a person's hand directly enters the electric vehicle battery socket, since the human body is a semiconductor, there should be little impact on the person. But if you hold a metal conductor, such as the coin used by the little girl, in your hand, it can have dire consequences. Because once a conductor enters, a short circuit will form in an instant, and the resulting large current may cause the metal body to be melted by electricity, which may also injure people.
A dealer of a certain brand of electric vehicles told a reporter from the Chongqing Morning Post that the state stipulates that electric vehicle manufacturers must mark safety words on the batteries. As for the current production of electric vehicles, corresponding protective measures are required for power sockets and other aspects.

Why do electric car batteries hurt people? Some media have reported before that electric vehicle batteries may injure people even when they are not charged. Is this true?
Mr. Qin, who is engaged in high-voltage safety work for electric vehicles, said that currently, there are indeed two types of electric vehicles on the market: "standardized" and "non-standardized". Standardized electric vehicles have an "anti-touch" device. Simply put, human fingers cannot reach in, let alone coins. And when a short circuit occurs suddenly, the battery insulation management system will break the circuit through a momentary power outage.However, some non-standardized electric vehicles still use lead-acid batteries due to price reasons. Similar to traditional batteries connected in series, the "electricity" is stored first after charging and released directly during use. The electric vehicle battery itself is a large-capacity power source, and its charging jack is the same as the socket used at home.
