1 Super fast charging loader is coming
Recently, Shanxi released a pure battery electric loader that is said to be a super cow. Let's first look at what the official news has to say.
It is said that its battery system uses the world's most advanced super-rechargeable battery, the maximum charging speed is 6 times that of ordinary batteries, and it only takes 15 minutes for the battery to reach 80% from 10% to 80% at 720kW charging power.
This loader is jointly built by Gerun Times Hydrogen Electric Equipment Manufacturing (Shanxi) Co., Ltd. and CITIC Electromechanical Special Equipment (Shanxi) Co., Ltd., according to their official statement, this is the world's first super fast charging loader, model 955H-1EV.
It is said that this supercharge loader has achieved two breakthroughs in the field of new energy: one is to solve the problem of long charging time and too long heating time during charging, and the other is to extend the service life of the battery and improve the charging performance of the whole machine.
2 Do you want to reduce the dimensionality of the current electric loader?
Why do they emphasize this fastness so much? Because in the current pure battery electric loader products, it generally takes more than an hour to charge, which is still relatively fast, and it may take more than 5 hours to charge slowly. We have collected some introductions about the charging time of electric loaders as follows:
At this charging speed, the manufacturer generally introduces a night first, the next morning to work worry-free, and then noon to eat for an hour or two, and work in the afternoon without worry. But it's basically this working time, and I can't work overtime.
Therefore, the superiority of this ten-minute charging time is reflected, there is no need to wait for the charging time, and the electricity will be full when you take a break to go to the toilet.
First of all, we look at the introduction of this text to say that 10%-80% takes 15 minutes.
Then there is an official video that says that it is fully charged in 18-20 minutes and lasts for 5-8 hours. Well, even if it's a 20-minute fill, that's incredible. When there is no electricity, the electricity will be full after a break, and the work will not be delayed at all, which basically realizes the non-stop work.
This is okay, and the working capacity of the current electric loader is completely surpassed, which is simply a dimensionality reduction blow. So who still uses that hour or two?
In this way, it really has an effect, the manufacturer news said, just launched like this, this electric loader has been ordered out more than 100 units, more than 100 units, about 100 million.
3 Exploring the secrets behind supercharging
How did he do this super fast charging? It is also very clear in front of the front, according to the official statement, one is the use of super rechargeable batteries, and the other is the use of 720KW charging power.
So what is the current charging power of other manufacturers?
XCMG XC958-EV electric loader (official introduction): XC958-EV electric loader is equipped with a 282kW·h lithium iron phosphate battery as standard, and the battery has a heating module function to meet the requirements of low-temperature environments. It supports dual-gun charging, and uses a 240kW DC fast charging station to fully charge 90% in one hour. After full charge, it can work continuously for 6~8 hours.
Liugong 856E-MAX loader (official introduction original): fast charging, when the charging pile power is 240kW, charging only takes 1 hour, if the 300kW charging pile is used, charging only takes about 48 minutes. It can be used continuously for 6~10 hours under normal working conditions, and 4~6 hours of continuous operation under heavy load conditions.
Sany SW956E-MAX: The theoretical charging time of charging piles above 300kw < 1 hour.
We can see that the power of the current pure electric loader charging pile is generally two or three hundred kilowatts, and Gerun directly dried the power of the charging pile to 720kw, theoretically speaking, the charging time is of course fast. If other companies do the same, then everyone should have about the same amount of time, right?
Then this question comes, declare in advance, we are not raising the bar and malicious guidance, just ask if you don't understand.
1 Why can't so many companies, including XCMG and Liugong Sany think of this kind of plan?
2 How much will this scheme increase the cost of the whole machine? You say that the price is about the same, but it is definitely impossible.
3. How high is the requirement for the battery of this high-power solution, and is there any higher requirement for the safety of charging, etc.
