Fast charging and slow charging are relative concepts. Generally, fast charging is for high-power DC charging. It can fill 80% of battery capacity in half an hour. Slow charging refers to AC charging. The charging process takes 6 hours -8. The charging speed of an electric car is closely related to the power of the charger, the charging characteristics of the battery, and the temperature. At the current battery technology level, even if fast charging requires 30 minutes to charge to 80% of the battery capacity, more than 80% is to protect the battery safety, the charging current must be small, and charging to 100% will be longer. In addition, when the temperature is low in winter, the battery requires a smaller charging current and the charging time becomes longer. Slow charging is the safest and most common charging method for electric vehicles. It usually takes more than 6 hours to fully charge. The owners usually choose to charge the car at night. However, when the electric car is running low during the day? Even if you find a fast-filled pile, it takes at least two hours to fully charge. As a result, more and more fast charging technologies are constantly coming out. In the near future, it is very likely that electric vehicle charging will be as convenient as fueling a fuel car. Today, I will meet these new technologies with Fan Erjie. Tesla Super Charging Station: 80% in 40 minutes We all know that the current fast-charged piles of the State Grid have a current of 50A, and the car can be charged 80% in 1-2 hours. The maximum charging current of the charging socket of Tesla's super charging station can reach 80A, and it can charge 80% in 40 minutes. However, unfortunately, Tesla's super fast charging pile can only support Tesla's model charging. Recently, Tesla announced plans for the construction of a super charging station in China in the second half of this year. Tesla said, "At the end of the year, when the super-charged piles in the western regions such as Mianyang and Yibin are gradually completed, whether they are south or north, the owners can choose. The pure electric self-driving route will be more abundant and smooth.†Some netizens said, “13% of Tesla has been bought by the Chinese, so many charging piles are not enough!†Can filmless battery charging be as convenient as refueling? Recently, researchers at Purdue University in the United States have developed a new type of battery, which is a membrane-free battery that replaces used battery fluid with a new liquid electrolyte, just like refueling at a gas station. In addition, the used battery fluid or electrolyte can be collected and sent to a solar power plant, a wind power plant, or a hydroelectric power plant for charging, turning it into an electrolyte, and recycling it. Eric Nauman, a professor at Purdue University, said that designing and building enough charging stations requires a large-scale charging infrastructure that is costly, and that the membrane-free battery pack is not only safe, but can be installed in a home, with stable performance and cost. Not high enough to meet production and sales requirements. However, Fan Erjie seems that although this battery has many advantages, it is still unrealistic at present for mass production in China. After all, China's access to foreign power batteries is still in a restricted stage. FlashBattery: charging for 5 minutes, driving for 483km Some time ago, a FlashBattery ("flash" battery) technology developed by Israeli nanotechnology company StoreDot disrupted our nerves. The company claims that the new technology battery can be charged in as little as 5 minutes and can support electric vehicles. Continue driving for 483km. Cleverly, cars running on flash-filled battery modules will be equipped with forty "small bags", each containing FlashBattery technology, consisting of "nano dots" converted from short chains of amino acids called peptides. The "nano dots" are arranged in a layered structure, and these pouches are combined to form a charging module. In addition, it is known that compared with lithium batteries, the battery has the characteristics of being non-flammable, and breaks the limitation of the traditional graphite lithium battery. The internal resistance of the fast-charging battery is very small, and the heat generated during charging is also higher than that of the ordinary battery. To be small, its life expectancy is about three times that of a normal lithium battery, and the charging cycle is about 1500-2000 times. Although the cost of manufacturing this new type of battery is 20%-30% higher than that of a normal battery, its advantage is that it has a long service life and is considered to be more affordable than a lithium ion battery. High-voltage air charging system: charging for 48 minutes for 48km Previously, the high-voltage air charging system developed by electric car manufacturer Proterra claimed to be able to fully charge an electric bus in 10 minutes. How did it do it? It is understood that the high-pressure air charging system uses machine control technology, the bus is equipped with auto-driving software, and it can fully charge the 100-kilowatt electric bus in 10 minutes, enough to make the circular bus travel about 48 kilometers. Of course, the specific charging time is determined by the size of the battery. If you charge with 250-1000 volts DC, the current is up to 1400 amps, the system's charging speed is 9 times that of the CHAdeMO fast charging standard, and the Bitsla super charging station is 3-4 times faster. It is worth mentioning that the bus is usually powered by an old-fashioned transmission frame, but the transmission frame needs to be installed on the entire route of the car, and the Proterra system is stationary. In other words, the bus operator can install the system near the terminal or the gas station. If this technology is really applied to the country, it will be expected to alleviate the pain points of electric bus charging time.
