How to plan BYD to make EV charging faster like a gas tank filling

The Chinese -Chinese BYD BYD company has made this week when it announced that the new Han L Sedan could add up to 248 miles of the range in less than five minutes.

Unfortunately, the company highlighted the details, and did not respond to the Techcrunch request for clarification. Instead, we searched for the web to get information, fill the gaps to determine exactly how BYD enables to make EV can recharge apparently at the speed required to fill the gas car.

What we found mostly supports car makers claims, with a few warnings.

Battery package

Fast charging is in Han L’S fast in internal electrical infrastructure. It starts with the battery, which According to To Carnewschina, the martyrdom of organizational documents, is a package of 83.2 kW in Wiwo Wiw Iron Phosphate (LFP) that works in 945 volts. (In its marketing materials, it seems that the company has collected it and recounts it at a speed of 1000 volts).

The battery chemistry is likely to be essential in the possibility of rapid charging of the car. LFP batteries have always been considered stability and safety; They do not shoot easily like other species as NMC cobalt. They can also charge faster due to some electrochemical dodes inherent in the Cathode-Anoud design of the LFP cell. (There is great Chip surface From the National Renewable Energy Laboratory, which explains the cause in more detail.)

Moreover, BYD works with LFP for years, and the latest battery structure, known as Blade 2.0, is expected to appear in the new car. Perhaps this experiment gave the company’s engineers a good feeling of the extent they can push for batteries and electrical architecture.

Electrical system

Battery package feeding is a high -voltage electric system that works at 945 volts. The car manufacturer continues to be more than ever because the highest voltage generates less heat, allowing more energy safely and efficiently. Lucid currently runs 900 volts brown in its cars, and many others such as Hyundai Kia and Porsche 800 volts work in many of them. With Teslas, this depends on the car: Cybertruck is used with a structure of 800 volts while the rest works on about 400 volts, or gives it, depending on the model.

Add everything and you can charge Han L charging up to 1 megawatts, or 1000 kW. The fastest EV charging devices are widely available in the United States today providing only 350 kW.

But even when running at 945 volts or 1,000 volts, the amount of heat resulting from 1 megawatts is important, and the cables to support them will be incredibly thick. Even the cables are slower and fast charging, such as those that are passionately linked with a passion for 350 kilowatts, which are wrapped in liquid cooling, which increases their size.

Perhaps in an attempt to make charging cables more manageable, BYD has adopted what you call a double gun: the car contains shipping outlets, each of which can connect a 500 kW charger at one time.

Together, they provide one megat.

The Childhan range

According to BYD, this allows the car to add 248 miles of the range (400 km) in five minutes.

Unfortunately, drivers are unlikely to travel after these fast fees. This is because the Chinese equivalent of the EPA, CLTC test course, optimistic. It is 35 % higher EPA classifications, According to To INSIDEEVS, which is either immediate or optimistic depending on the amount of driving on the highway.

Realistically, drivers can expect about 160 miles of charging from five minutes and about 280 miles from a full battery. For more comparison between apples from apples, it is useful to look at the period that the charging takes from 16 % to 80 % (in 10 minutes) or from 16 % to 100 % (in 24 minutes). Regardless of how to cut it, this is very fast.

Shipping strategy

But EV’s charging speed is not as good as the shells and how wide it is available. To this end, BYD undertakes to install more than 4000 of them across China. Each plant will require large promotions of networks, although it is possible that the withdrawal of power 1 megawatts will force the current infrastructure.

When will we see this in the United States? Do not rely on the ability to buy Han Lid any time soon, even if the start price of approximately $ 37,000 will give the market a welcoming tremor. Chinese EVS is currently subject to a 100 % tariff, raising prices to the point that they are not competitive.

But this does not mean that fast charging will remain far for the Americans. The cars offered for sale today can impose fees from 20 to 80 % in 18 minutes, so they are a matter of time only before car manufacturers decrease those times.
