Sunwoda claims new LFP battery charges in under 10 minutes

EV drivers often complain about one thing more than anything else: the time it takes to charge. Gas cars fill up in minutes, but EVs usually need a longer break. Sunwoda Power shared some news that might change that. At an event in Beijing, the company showed off a new battery that can charge pretty much as fast as you can refill a gas-powered car.

The new tech is called the Xingchi Supercharge Battery 2.0. It uses a chemistry known as lithium-iron phosphate, or LFP. These types of batteries are known for being tough and safe, but they aren't always the fastest. Sunwoda says it has fixed that. Their new pack has a "15C" charging rate - this battery can handle a massive amount of power all at once without melting or breaking.

The numbers Sunwoda shared are quite impressive. If you plug in an EV with this battery when it is at 5%, it will hit 95% in just 9 minutes. If you are in a real rush, it can go from 5% to 75% in only 5.5 minutes. Most people spend more time scrolling through their phones in a parking lot than it would take to nearly fill this battery.

Surprisingly, Sunwoda did not make a small prototype - they showed off a full-sized battery pack. This pack uses 264 prismatic cells, has a total capacity of 98.8 kWh, and runs at 844.8 V. That is definitely enough energy to power a large sedan or SUV for a long trip.

When you push that much power into a battery, people worry about heat and damage. Sunwoda seems very confident in its work. The company announced that drivers can use ultra-fast charging as much as they want during the warranty period. They are not putting a limit on how many times you can use the fastest chargers.

The battery can handle a maximum current of 1,800 A, but even with all that power, Sunwoda claims the battery will last for more than 1,500 charging cycles. For most drivers, that means the battery will likely outlast the car itself.

Not everyone needs a massive battery for long trips. Some people prefer hybrid vehicles that use both gas and electricity. Sunwoda introduced a different battery for these vehicles. It uses large cylindrical cells that are 1.81 inches wide. These packs range from 3 kWh to 7 kWh.

Lithium is still the king of batteries right now, but Sunwoda is looking at other materials too. They are working on sodium-ion batteries, since sodium is much easier to find than lithium. These batteries are cheaper and safer, but there is a catch. Sodium batteries cannot hold as much energy in the same amount of space as lithium ones. Because of this, Sunwoda plans to use them for cheaper, entry-level EVs or for low-voltage systems in cars.

Sunwoda is also bringing artificial intelligence into the mix. They call it their "AI+ battery" strategy. They use computer programs to help design the batteries and keep track of them while people are driving. This helps the company find ways to make the batteries better and safer over time.

Of course, not wanting to be left out, the company is working on solid-state batteries. These are the "holy grail" of the industry. Their prototype can hold 400 Wh/kg of energy and could potentially give a car a range of 620 miles on a single charge.

Business-wise, Sunwoda is holding its ground. In March 2026, they installed 1.4 GWh of batteries into new EVs. This gives them about a 2.5% share of the massive Chinese battery market. They also recently finished a legal battle with a branch of the car company Geely. The dispute was worth $323 million, and it has now been settled.
