In recent years, electric vehicles have gradually become the means of transportation for the citizens of our city. It brings convenience to the public, but many electric car owners often encounter such awkwardness: the destination is not there, but the car is out of power. Many merchants “sniffed†the business opportunities and added “electric vehicle fast charging stations†in front of their own stores to start a business of charging and charging. To this end, the reporter conducted a visit. “Electric Vehicle Fast Charging Station†appeared in many places in the event city At 2 pm on February 3, Huang Daye, who lives in Lantian Village, Jiaocheng District, went to the city to purchase new year's goods. When the electric car rided to the East Lake Market, he found that there was only one grid of electricity left, so he found a fast repair point for an electric car nearby. Charging station charging. "Come here has been charged several times, and one dollar can be charged for 10 minutes. Generally go home from here, about 30 minutes." At the electric vehicle maintenance point, the reporter saw a yellow box with a height of about 50 cm, marked with the words "electric vehicle fast charging station", "convenience project", "quick environmental protection" and so on. "This equipment is an emergency charging device for electric vehicle lead-acid batteries. When charging, you need to turn off the electric vehicle power supply. You can run for 3 to 5 kilometers for one yuan." The electric vehicle maintenance point operator told the reporter. Coincidentally, the “Electric Vehicle Fast Charging Station†at a milk powder shop in Jiaocheng North Road is placed at the door, and several different types of charging plug power cords are scattered on the ground. The important prompt on the "quick charging station" reads "This charging station uses a microcomputer to limit the voltage, control the charging current, and charge the battery without loss, please feel free to use it." During the reporter's visit, it was found that most of the fast charging stations are only branded, and some of them have contact information. Most of the surface of these brand fast filling stations are not marked with the manufacturer, production certificate, production standard number, etc. The public’s views on new things are mixed Since the "fast charging station" can complete the charging in a short time, many citizens praised the service. "Electric vehicles ride in the middle of the road without electricity, occasionally happen. With this fast charging station, you can charge at any time, eliminating the embarrassment that electric vehicles can't go without electricity." Ms. Zhang said. "It is the first time I heard that there is such a fast charger in the urban area, and I have the opportunity to experience it." Xiao Wang, a college student at Ningde Normal University, said. While the "fast charging station" provides convenience, many citizens question whether it will affect the battery of electric vehicles. "I don't know if this kind of 'quick punch' causes secondary damage to the electric vehicle battery." Ningde netizen @red Red told reporters. “Does the fast charger seem convenient, but actually at the expense of battery life?†Resolve fast charging and shorten battery life With the doubts and incomprehension of the citizens, on the 4th, the reporter went to the Physics Department of Ningde Teachers College to understand the relevant situation. The physics teacher of the department, Mr. Wang, said that the rapid charging has a greater damage to the battery of the electric vehicle. "At present, the electric bicycle battery in our city is mainly alkaline battery. Most of the fast chargers on the market use high-voltage and high-current pulse charging. The current is generated by the oxidation reaction and the reduction reaction on the two electrodes respectively. The faster the internal reaction of the fast battery, the faster the polarization of the battery plate and the shorter the battery life." Teacher Wang said that alkaline batteries are often connected to the electrolyte solution by using two kinds of metals (or graphite) with different reactivity, and the two react to generate electric energy. The electric vehicle charging process is the reverse process of the electrolysis reaction, allowing the positive and negative electrodes to reattach and adsorb metal ions. If the fast charger is used frequently, it will affect the effect of the metal and electrolyte solution in the battery on the metal ions, which will affect the normal life of the battery of the electric vehicle.
