To charge 40 kilowatt-hours of new energy vehicles for an hour, a charging pile with a power of more than 40kw is required. The electricity fee is determined according to the local charging standard. For example, 1 yuan per kilowatt-hour of electricity is 1x40=40 yuan. Many places have an interval price, such as the electricity price interval price in Shenzhen, Guangdong, where 11:00 p.m. to 7:00 a.m. is 0.29 yuan/kWh, the peak electricity price is 0.71 yuan/kWh, and the peak electricity price is 1.06 yuan/kWh. Take a car running 210 kilometers as an example, using charging piles to charge. At present, the charging price of mainstream charging piles is between 1.5 yuan and 1.9 yuan per kilowatt-hour. It takes about 31.5 kilowatt-hours to fully charge, and the price is between 47.25 yuan and 59.85 yuan. And if you are using a charging pile for household electricity, the price is uniformly around 0.57 yuan per kilowatt-hour. If it is fully charged, the approximate price is about 18 yuan, which is relatively favorable, and if you use household electricity to charge , it is very likely that there will be a higher discount, because the price in some cities is even less than 50 cents, and a full charge only costs 15.5 yuan, which is really very affordable. It is estimated that everyone knows that new energy vehicles are the development trend of future automobiles, but limited to the basic charging facilities and the mileage of pure electric vehicles, the sales of electric vehicles have not risen. Of course, major car companies are also increasing through technology iterations The cruising range of your own electric model may be working hard on the charging method. The charging piles currently built support two modes of charging, slow charging and fast charging. This is like our mobile phone charging, which has two modes of fast charging and slow charging. In fast charging mode, the battery can be fully charged quickly, at least 40% faster than slow charging. The car charging here is also a similar concept, but the efficiency is much higher than that of mobile phones. However, what riders need to know here is that fast charging and slow charging are two concepts. Slow charging is AC charging, and the time to fully charge is generally 5-8 hours. In this charging mode, the battery suffers the least damage. Fast charging is an emergency charging method, which uses high-power DC charging (there is also AC fast charging). The voltage of this DC charging is generally higher than the battery voltage, and the AC power needs to be converted into DC power through a rectifier device. Power battery The voltage resistance and protection of the battery pack put forward higher requirements, and the charging current is large, which is ten times or even dozens of times that of the conventional charging current. A large number of electrons flow from the positive electrode to the negative electrode at a very high speed. The charging time of fast charging generally takes 30 minutes to charge 80% of the electricity.
