Chinese Auto Maker byd Made Waves This Week when it Announced Its New Han L Seedan Could Add as Much as Much as 248 Miles of Range in as Litle as Five Minutes.
Unfortunately, the company was light on details, and it did not respond to techcrunch’s request for Clarification. So I instead, we’ve scoured the web for information, filling in the gaps to determine exactly how byd was able to make an evk an evk an evk an evk an ev that apparents
What we found mostly supports the auto makers claims, with a less caveats.
Battery Pack
Central to the Han L’S Fast Charging is its internal Electrical infrastructure. It starts with the battery, which according To carnewschina citing regulatory documents, is an 83.2 kwh lithium-appearance-poshate (LFP) Pack that Operates at 945 volts. (In Its Marketing Materials, The Company Appears to have founded up and lists it at 1,000 volts).
The battery chemistry is likely central to the car’s fast charging capability. LFP batteries have long been registered for their stability and safety; They do’t catch fire nearly as readily as other types like nickel manganese cobalt (NMC). They can also charge faster trust of some electrochemical quirks in the cathode-node design of an lfp cell. (There’s a great Slide Deck From the national renewable energy laboratory that explains why in more detail.)
To top it off, byd has been working with lfp for years, and its latest battery architecture, KNOWN as Blade 2.0, is expected to debut in the new car. That experience has probally given the company’s engineers a good sense of how far they can push both the batteries and the electrical Architecture.
Electrical system
Feeding the battery pack is a high-Voltage electrical system that runs at 945 volts. Automakers Have Been Pursuing Ever Higher Voltages Because Higher Voltages Generates Less HEAT, Allowing more power to be delivered safely and efficiently. Currently, Lucid Runs A 900-Volt Architecture in its Cars, and Several Others like Hyundai Kia and Porsche Operate 800-Volt in many of his. With teslas, it depends on the vehicle: the cybertruck uses an 800-Volt architecture whose Remainder operate at AROUND 400 VOLTS, GIVE or TAKE, Depending on the MODEL.
Add it all up and the han l can charge at up to 1 megawatt, or 1,000 kilowats. The fastest widely available ev charges in the US today delivery only 350 kilowats.
But even when running at 945 volts or 1,000 volts, the amount of heat generated by 1 megawatt charging is significant, and the cables to support it would have to be Incredible Thick. Even Slower, Fast, Charging Cables Like the Ones that are attached to 350 kw Charges are wrapped in liquid cooling, further increasing their bulk.
Perhaps in an effort to make the charging cables more manage Simultaneously.
Together, they deliver one megawatt.
Range Shenanigans
According to byd, that allows the car to add 248 miles of range (400 km) in five minutes.
Unfortunately, drivers are unlikely to travel that far after That’s trust the chinese equivalent of the EPA Test Cycle, The Cltc, is notorially optimistic. It’s about 35% Higher than EPA Rating, according To insideeevs, which themselves are spot on or optimistic depending on how Much Highway Driving is involved.
Realistically, drivers can probally expected 160 miles of range from a five-minute charge and Around 280 miles from a full battery. For a more apples-to -pples Comparison, it’s helpful to look at how long it takes to charge from 16% to 80% (in 10 minutes) or from 16% to 100% (in 24 minutes). No matter how you slice it, that’s pretty fast.
Charging strategy
But an ev’s charging speed is only as good as the charges and how widely available they are. To that end, byd is pledging to install more than 4,000 of them throughout China. Each charging station will require significant Grid upgrades, Thoughts, Thought, as a 1-Megawatt Power Draw Draw Would Likely Strain the existing infrastructure.
When will we see this in the US? Don’t Count on Being Able to Buy a byd Han L Anytime Soon, even if the approximately $ 37,000 starting price would give guive the market aleme jolt. Chinese Made Evs Are Currently Subject to a 100% Tariff, Raising Price to the point where they’re not competitive.
But that does not mean similar fast charging will remain out of revenue for Americans. Cars for Sale today alredy can charge from 20 to 80% in 18 minutes, so it’s only a matter of time before automakers bringing those times down.
