BYD’s Yangwang U7 gets new 1,000 km battery

Until now, car makers had to make a tough choice when it came to electric cars. They could give a car a lot of power, a long driving range, or fast charging. Usually, they could only pick one or two. The auto industry calls this the "impossible triangle." If you wanted a car that could go fast, the battery would run out quickly. If you wanted it to travel far, it usually couldn't charge very fast. BYD claims they have finally solved this puzzle with their new luxury car, the Yangwang U7.

The 2026 Yangwang U7 is the first vehicle to use the second-generation Blade Battery. This battery holds 150 kWh of energy which helps the U7 to travel up to 625 miles on a full charge. That is a very long way for any electric car on the road today. Most people get nervous about how far they can drive before they need to look for a charge, and this car can take that fear away.

Hu Xiaoqing (the Yangwang brand boss) explained that making an electric car is usually a balancing act. She noted that high power often hurts how long a battery lasts. If you want a car to accelerate like a rocket, you usually have to give up some distance. Also, fast charging usually requires smaller batteries, which means you can't drive as far. It seems like you can't have everything at once.

The Yangwang U7 tries to prove that wrong. It uses a "Super Quad-Motors" system - it has four separate motors, one for each of the wheels. Having four motors uses a lot of electricity, but according to the company, the new Blade Battery is strong enough to handle all that power while still traveling over 620 miles. This is the first time a car with four motors has been able to go that far.

How did they do it exactly? The experts at BYD say it comes down to basic science. Usually, big batteries that hold a lot of energy are hard to cool down and hard to charge quickly. If you push too much electricity into them at once, they get too hot. This can damage the battery or even be unsafe. The second-generation Blade Battery uses new designs to manage heat better.

This is a big step up from the first Blade Battery that came out in 2020. The original was famous because it was very safe and lasted a long time. It was made of lithium iron phosphate. BYD's goal was to make a battery that was as safe as a block of wood but could hold as much energy as the "fast" batteries other companies were using. They seem to have doubled down on that idea for this new version.

We will get to see all the official details at BYD's event on March 5 at the Shenzhen Universiade Sports Centre. They plan to show off the new battery and a new "flash-charging" technology. This technology is supposed to fill the battery up much faster than older chargers. For people who drive electric cars, being able to "refuel" in minutes instead of hours is a huge difference.

Other cars in the BYD family are also getting better. The Denza Z9 GT is another new car that can travel over 620 miles, but that car only uses one motor to get that range. The fact that the Yangwang U7 can do it with four motors is what has the car world talking.
