It is undeniable that the acceptance of electric vehicles in people's hearts is getting higher and higher, and buying an electric car to solve daily travel is not only a trial behavior of a small number of people, but a solution to solve the daily travel needs of more people. But the more such a booming market performance, the more important the practicality of electric vehicles, and each manufacturer has a slightly different solution to solve the user.
"The parking lot next door to the company hasn't been fixed yet?" There is no place in the parking lot downstairs every day," Peng Dacang began to complain as soon as he entered the office.
"After fixing it, you can't stop it" Xiao Zeng looked at his bubbling appearance and began to mend the knife again.
"Huh? Why can't I stop? Isn't that a public parking lot? ”
"That's not a parking lot, it's a charging station for electric cars, didn't you see that it was repaired by the public power grid?" After saying that, he looked at Peng Dacang's expression, and when he saw that Peng Dacang was frustrated, Xiao Zeng pretended to be serious and showed a smile on his face.
"Wasted so many places only built a charging station? Now the parking lot is not enough, it is better to repair the parking lot."
Indeed, it seems that there are more and more electric vehicle charging stations around us, and the charging of electric vehicles seems to be really more and more convenient. But it seems that like Peng Dacang, there are many people who feel that electric vehicles occupy parking spaces. In fact, the key to this problem is that the charging efficiency of electric vehicles is low, and each charge will use a parking space for a long time, resulting in the impression that the fuel vehicle owner has caused an electric vehicle charging waste parking space, after all, the fuel model refueling is immediately added. And now in order to solve the anxiety of endurance, electric vehicles have generally increased the mileage, which undoubtedly exacerbates the phenomenon of long charging time of electric vehicles.
Taking the salon mech dragon of this year's auto show as an example, the mecha dragon is equipped with the latest independent research and development of the Great Wall Dayu battery, the battery capacity is 115kWh, under CLTC working conditions, the mileage can reach up to 802km, while supporting 800V super fast charging, the peak current is as high as 600A, and the endurance of charging for 10 minutes is increased by 401km (CLTC standard). Also using the 800V charging platform is Porsche, and the charging pile set up by Porsche Taycan in Porsche can also enjoy 800V fast charging. Of course, Porsche is not stuck in its own way, Porsche this year's new Release mission R is equipped with dual motors in front and rear, the motor output power on the front axle is 320 kW (435 PS), the motor on the rear axle is 480 kW (653 PS), the total power is 1088 horsepower, the battery capacity of the Mission R is about 80 kWh Under the 900V high-speed charging system, it takes only 15 minutes to complete 5%-80% charging, and the charging power can reach up to 340 kW.
Look at Tesla, which is felt by China's new power brands, which has surpassed tesla, and the current Tesla V3 super charging pile has a maximum charging power of 250kW. The Model 3 model that supports fast charging can be charged for 15 minutes and have a range of 250km. It can be said that the kung fu of stopping for a meal has been charged with 80% of the electricity. Like the BAIC BJEV EX3, which has the endorsement of traditional large factories, it also supports a charging power of 160KW. And the self-developed charging technology, which is said to be able to achieve 400A DC fast charging under 700V high voltage, and the maximum charging power can reach 280KW. Faster.
Although major manufacturers have invariably adopted high-voltage charging schemes, this high-voltage and high-current scheme also has no small requirements for the heat dissipation capacity of charging equipment, of course, more is also a high demand for the thermal management of the battery. Therefore, most of the current super fast charging stations are still set up in outdoor parking spaces, and the battery thermal management system, major manufacturers have also been upgraded to meet the increasingly harsh battery use environment. But at present, it seems that the charging time is still dragging down the overall use of electric vehicles.
"In fact, if you want to use those parking spaces, there is a way" Xiao Zeng began to flirt with Peng Cannon again.
"I park the parking space of the charging pile, and the owners of those electric vehicles don't mess with me?"
"Who lets you park the fuel car directly, you buy an electric car to charge a slow charge, the cost of charging is not expensive than the parking fee"
"Hey, it seems like a way to do it, but I'm going to buy an electric car for this?"
"It's up to you"
Write at the end:
In order to improve the battery life anxiety of electric vehicle owners, the vast majority of manufacturers are desperately increasing the mileage, and the larger battery capacity also makes the charging time of electric vehicles the most degrading part of the electric vehicle experience. In the current era where power exchange services have always been difficult to become the mainstream, how to shorten the charging time of electric vehicles under the premise of safety is the key to making electric vehicles truly enter thousands of households to replace the existence of fuel vehicles.
