The Chinese auto -maker Bid made waves this week when it announced that its new Han L. Sidan could be included in the minimum 248 mile range in five minutes.
Unfortunately, the company was light on the details, and it did not respond to the Tech Crunch request for clarification. Therefore, instead, we have hollowed out the WeB web of information, and to determine how BYD is able to create an EV that can apparently recharge the taxes of the gas car.
What we find is mostly supports the claims of auto makers, which have some warnings.
Battery pack
The main center of Han L’s fast charging is its internal electrical infrastructure. It starts from the battery, which According to Referring to Regulatory Documents to Carnoschina, an 83.2 kW Lithium Iron Foesfat (LFP) pack works on 945 volts. (In its marketing content, the company has helped it and listed it in a thousand volts).
The battery chemistry is potentially central to the ability to charge the car. LFP batteries for a long time for their stability and safety. Understanded They do not easily catch fires like other types like Nickel Manganese Cobalt (NMC). They can also charge rapidly due to some electrochemical prices included in the LFP cell’s cathode anode design. (A very good Slide deck The National Renewable Energy Laboratory, which explains why in more detail.)
To eliminate this, BYD has been working with LFP for years, and its latest battery architecture, known as Blade 2.0, is expected to be debuted in the new car. This experiment has probably given the company’s engineers a good sense of how they can advance both batteries and power architecture.
Power system
Feeding the battery pack is a high voltage electrical system that runs on 945 volts. Automackers are sometimes pursuing high voltage as high voltage produces less heat, which allows more power to be delivered safely and efficiently. Currently, Lucid operates 900 volt architecture in its cars, and many other people like Porsche and many other people run 800 of them. With the teslas, it depends on the vehicle: Cyber truck uses 800 volt architecture, while the rest works, gives or takes about 400 400 volts in terms of the model.
Add all this and charge Han L1 MW, or 1,000 kW. Today, the fastest available EV chargers in the United States provide only 350 kW.
But even when running on 945 volts or 1,000 volts, the heat generated by 1 MW is important, and the cables will have to be incredibly thick for support. Even slowly, sharp, charging cables such as 350 kW are attached to the chargers, liquids are wrapped in cooling, which further increases their numbers.
Perhaps in an attempt to make the charging cables maximum managed, BYD has declared it a double gun approach: the car has two charging ports, each of which can be plugged in 500kW chargers simultaneously.
Together, they provide 1 MW.
Range Schinnagan
According to BYD, it allows the car to add 248 miles (400 km) in five minutes.
Unfortunately, drivers are unlikely to travel after such a sharp charge. The reason for this is that the EPA test cycle is equal, CLTC, the notorious hope. This is about 35 35 % higher than the rating of the EPA, According to For internals, which is hoped for on its own, depends on how much of highway driving is involved.
Realistic, drivers may expect about 160 miles from a five -minute charge and 280 miles from a full battery. Compared to apple more than apple, it is helpful in seeing how long it takes 16 % to 80 % (10 minutes) or 16 % to 100 % (24 minutes). It doesn’t matter how you give it a piece, it is very fast.
Charging strategy
But the charge speed of an EV is just as good as the chargers and how extensive they are available. For this purpose, BYD is promising to install more than 4,000 of them all over China. Each charging station will require a significant grid upgrade, however, 1 MW power draw will potentially pressure the current infrastructure.
When will we see it in the US? At any time, do not trust if they are unable to buy Bai Han L, even if the initial price of about $ 37,000 will give a welcome shock to the market. Chinese -made EVs are currently subject to 100 TE tariffs, which raise prices to the extent where they are not competitive.
But that does not mean that in the same way, the Americans will be out of the rapid charging leakage. Today, cars for sale can already charge up to 20 to 80 % in 18 minutes, so automatic makers will only talk about time before they come down.
