Charging Time May Be A Problem For Electric Vehicles
Oh, wow!
Do you know that one of the biggest problems of electric vehicle charging is how long it takes? Yes, it depends on the charging system, the vehicle and the battery, but it may take several hours to charge the electric vehicle. As described in, some vehicles and some charging systems exceed 24 hours.
If you have to drive 200 miles, and your battery can only drive 120 miles, it will make things a little difficult. If you have a gasoline car(as most of us do) or a diesel car, you can fill the fuel tank in about 3 minutes, then rush into the office to pay, and leave in 5 minutes.
Unfortunately, this is not the case with electric cars. Therefore, if you need to drive 200 miles, you may need to charge the car on the way. If it takes an hour or two to recharge the battery, it will become a problem! In short, 200 miles is a long distance, but if you need to spend a few hours recharging the battery, it may become a nightmare.
This is why so many people were rejected by electric vehicles at the beginning. Yes, their price is about half of a mile. The motor doesn’t need all these services, so it doesn’t need all the services of gasoline or diesel engines, such as oil change, new plugs, etc.
But it does need to be charged, which may take a long time. Of course, if there is a roadside parking lot, you can set up a home charging station and leave. Just plug your car into the charger when you get home from work. When you wake up in the morning; the jar is full!
This depends in part on the charger. Some chargers take 30 hours to fully charge the battery under no-load condition. But if there is no empty battery at home and a reasonable charger, there will be no problem. Ideally, you need a two-stage charger that can charge most batteries in 10 hours or some batteries in 2 hours.
However, the length of time required for charging is the reason why so far many people are reluctant to invest in electric vehicles. Nobody wants to go to the countryside for an afternoon. Then he found himself trapped in the forest. really This is completely understandable.
Nevertheless, we will soon drive electric cars. If you remember, just a few years ago, we asked the milkman to deliver milk every Saturday. The milkman drives an electric milk cart: Remember?? Yeah, that was only 20 years ago!
I’ll be back that day. We should protect the environment. Believe it or not, as long as you had a family car in the 1940s, you must be very rich. Because most people don’t. Today, some families with more than millions of people, if not two or three, are one. But they will have to switch to trams.
This is better news. The problem of electric vehicles is the length of charging time, but some progress has also been made. One of the problems we found with lithium-ion batteries is that they decompose faster when they are charged too fast. The replacement cost is not low.
However, Dr. Wang Chao of Pennsylvania State University and his team developed a method to increase the battery temperature from 10 minutes to 60 ° C and then reduce it to 23 ° C during rapid charging. Dr. Wang said that electric vehicles can now be charged and have a range of 200~300 miles. Not only that, the process was repeated about 2500 times, so that the vehicle could travel about 500000 miles.
This development will mean that electric vehicles will be popularized faster than you think.
