Electric vehicle endurance anxiety is a big problem, the current solution to endurance anxiety in addition to increasing the battery capacity to ensure the mileage is to achieve rapid energy replenishment. There are two types of energy replenishment methods, one is overcharge, and the other is power exchange. Because the current popularity of overcharge and the number of users far exceed the replacement, many people say that supercharging is the future development direction, and the replacement will be replaced. So will the power exchange really be eliminated? Not necessarily, maybe it is a replacement to replace the supercharge! From the following analysis, it can be seen that power exchange is the future direction.
Power exchange vs overcharge
The convenience of power exchange is far more than that of supercharging. At present, the best in terms of supercharge is Tesla, the supercharge power is up to 250kW, 10 minutes to recharge more than 200km, this speed is fast? Fast, but compared with a few minutes to change the power directly to achieve full power, it can be said that it was completely exploded. Supercharge is not fast enough to change the power fast. At the same time, when the overcharge can not be stopped in a specific charging place, people are waiting there to waste time, not waiting and not ok, overtime to charge you money. Have been parked there to affect the use of others, not the parking lot but to charge the parking lot money, who wants?
The efficiency of the replacement power station is better than the charging pile of the explosion supercharging. A substation in a single location is only the size of that point. A charging pile footprint is indeed small, but is the parking place still small? The area used by two or three charging piles is equivalent to a substation, but the number of services served in the same time cannot be compared. At the same time, after charging, the car must leave, and if it does not leave, it will occupy the use of the next car. The substation does not have to worry about occupancy, while the charging pile needs.
Power exchange and charging costs the same, definitely choose better and more convenient services, electricity costs are the same, the power exchange time should be shorter, the power exchange service is better, and the battery is guaranteed. Some people will worry that their new batteries will be replaced with old batteries, feeling that they have suffered losses, but for the sake of service quality and safety considerations, changing the power plant will definitely ensure that the battery is no problem, and the battery with poor energy storage will be repaired or replaced. But the car that does not have the function of changing the electricity, the battery is lost when it appears, and the loss to a certain extent requires you to spend money to replace it, are you willing to spend money yourself?
In the future, the country will most likely support the popularization of power station replacement instead of charging piles. Fuel vehicles will definitely be eliminated, with the elimination of the progress, the country's gas stations will become meaningless, after all, do not refuel, but direct abandonment is impossible, will definitely choose to change it into a charging pile or change the power station, then change it to which is better? It must be a replacement power station, the time for changing the battery for a car and the refueling time of the gas station are basically the same, and the charging pile is changed, or the problem, the charging time is so long, has it been waiting there when charging? Always can't charge for a while and go straight. At that time, the batteries have been replaced at the power station, and the car has been fully charged and driven away.
In addition, the construction of the replacement power station does not need to be built slowly like the original gas station, and now it can be directly adopted in a cooperative way to transform on the basis of the gas station, and the cost can be greatly saved and the speed can be improved. Some people will worry that refueling and charging can be universal, but replacing the power can not. Can't it be now, but can't it be after that? Tesla did not support charging other cars before, but now it is not the same as support? There is a demand for the market, there is a market will be manufacturers to do, now only Weilai is promoting the replacement of power stations, but after more, the state will naturally formulate a unified replacement standard, just like Tesla and other manufacturers of charging piles.
And fast charging is now charging power is very good but can not always be high, has been improved the State Grid can not hold on, now the number of overcharge is not too much, if more how to do, maintain ultra-high power supply power is the problem. There is an upper limit to the number of supercharged piles, and now each family is accelerating the construction of its own charging piles, which can be said to be grabbing the number.
At the same time, after waiting for the replacement power station to be spread like a gas station, will someone choose the charging form, after all, the car is not a mobile phone, the mobile phone battery is eliminated by fast charging, the mobile phone can play while charging, and the charging place can be seen everywhere in life, and the charging device can be as convenient as the mobile phone charging?
Finally, the replacement tram can support overcharge, and now Weilai can also overcharge while changing the power, but the charging car does not support the replacement of the battery, and it can be selectively seen that it is obviously better to change the tram. As a consumer, a variety of choices is the best thing, so the future is not to say whether it can replace the supercharge pile, at least the replacement power station itself will not be eliminated, perhaps the two coexist, or directly is the charging pile directly eliminated.
summary
One more option is always good, just like the current vigorous development of electric vehicles, but hydrogen energy is also developing, as a source of power, hydrogen energy is indeed better. But now the technical problems can not be solved, as long as it is solved, will not vigorously promote hydrogen energy vehicles? It can only be said that electric vehicles are currently a better choice, but not the best choice, just like the current overcharge scale, is a better choice, but when the power exchange is popularized, it will eventually become a major trend.
The power exchange mode will be eliminated, and overcharge is the future direction? Is NIO going in the wrong direction?
Weilai "yaw"? The overcharge mode is the direction of development, and the power exchange mode will be eliminated?
