BYD, a Chinese automobile manufacturer, made a wave this week, saying that the new HAN L sedan can add 248 miles of range in five minutes.
Unfortunately, the company was bright about the details and did not respond to Techcrunch’s request for explanation. Instead, we were intervaled to search the web for information and make an EV that can be made quickly, as it takes to refill a gas car.
Most we have discovered, with some warnings, support the automakers’ claim.
Battery pack
The center of a fast charging of L is the internal electric infrastructure. According to Carnewschina, it is a 83.2kWh lithium-iron phosphate (LFP) pack that starts with a battery citing a regulatory document and works at 945 volts. (In marketing materials, the company appears to be rounded and lists in 1,000 volts).
Battery chemistry can be the core of the fast charging function of the car. The LFP battery has long been considered stability and safety. They do not fire as easily as other types, such as nickel manganese cobalt (NMC). It can also be charged faster due to some electrochemical quirky points inherent in the Casides-Annode design of LFP cells. (There is a great slide deck from the National Renewable Energy Laboratory, explaining why.)
In addition, BYD has been working with LFP for many years, and the latest battery architecture, known as Blade 2.0, is expected to debut in a new car. The experience has probably given the company’s engineers a good sense of how far they can push the battery and electric architecture.
Electrical system
Supplying the battery pack is a high voltage electrical system that works at 945 volts. Automobile manufacturers have pursued higher voltages because they have less voltage and can deliver more power safely and efficiently. Currently, Lucid operates 900 volt architecture in a car, and some other, such as Hyundai Kia and Porsche, operates 800 volts. Teslas depends on the vehicle. Cybertruck uses 800 volt architecture, while the rest works at about 400 volts and offer or take them according to the model.
If you add everything, Han L can charge up to 1 megawatt or 1,000 kilowatts. The most widely available EV charger in the United States today offers only 350 kilowatts.
However, even if it works with 945 volts or 1,000 volts, the calories generated by 1 megawatt charging are important, and the cable that supports it should be incredibly thick. The same slow, fast and fast charging cable as a cable attached to the 350kW charger wraps into liquid cooling to further increase the bulk.
BYD adopted a dual total approach to make the charging cable easier to manage. The car has two charging ports and each can be connected to the 500kW charger at the same time.
They offer 1 megawatt together.
Range shenanigans
According to BYD, this allows the car to add 248 miles of range (400 km) in 5 minutes.
Unfortunately, the driver will not travel much far after such a quick charging. This is because Chinese people, which are equivalent to the EPA test cycle, are notorious. According to Insidevs, it is about 35% higher than EPA.
In reality, the driver can expect a range of about 160 miles from a 5 -minute charge, about 280 miles away from the entire battery. For more apple -to -application comparison, it is helpful to take a look at 16% to 80% (10 minutes) or 16% to 100% (24 minutes). It is very fast, even if you slice it thinly.
Charging strategy
However, the charging speed of the EV is as superior to the charger and how extensive it can be used. To this end, BYD promises to install more than 4,000 people across China. The 1 megawatt power lottery can be tense on the existing infrastructure, so each charging station requires a significant grid upgrade.
When can we see this in the United States? Do not think that even if the starting price of about $ 37,000 can be welcomed to the market, you can buy BYD Han L soon. The Chinese EV is currently receiving 100% tariffs and raises the price until it is without competitive.
But this does not mean that similarly fast charging does not reach Americans. The cars sold today can already be charged at 20-80%in 18 minutes, so it’s only time for automakers to take time.
