"Technology is king, and innovation is fundamental."

On June 12, at BYD's headquarters in Ping Shan District, Shenzhen, a wall adorned with the phrase showcased hundreds of patents. The company, originally a battery producer for gaming devices, has transformed into the world's leading eco-friendly vehicle manufacturer, recognized for its technological prowess both domestically and internationally.

The showroom featured BYD's E-Platform and Blade Battery (LFP), alongside the newly launched mid-size electric SUV, the Song Ultra EV, which debuted in China this year.

Equipped with a second-generation Blade Battery, the Song Ultra EV boasts an impressive range of over 710 kilometers on a single charge. Using a FLASH ultra-fast charger, the battery can be fully charged in just nine minutes, significantly faster than the 20 minutes required to charge 80% at standard fast-charging stations. A BYD representative remarked, "You can finish eating a cup of instant noodles and have your car fully charged."

Local demand for the Song Ultra EV has been strong. After its launch at the end of March, 37,216 units were contracted within a week, and total orders reached 61,240 within a month. This surge in demand has led to delivery delays of two to three months in some areas.

Despite the advanced battery technology, the starting price remains competitive at 151,900 yuan (approximately $34,120). The vehicle is expected to launch in South Korea as early as next year.

BYD aims to soar once again with its second-generation Blade Battery. After surpassing one million units of the first-generation model launched in 2021, the company achieved a cumulative production of 15 million units just four years later. It plans to continue this growth trajectory with the new generation.

At the event, a safety comparison experiment was conducted between BYD's Blade Battery and traditional nickel-cobalt-manganese (NCM) batteries. When punctured, the NCM battery exploded and experienced thermal runaway, while the Blade Battery showed no adverse effects. This demonstration aimed to dispel the perception that lithium iron phosphate (LFP) batteries lack durability. The company also showcased battery performance by rapidly charging vehicles in extreme conditions at minus 30 degrees Celsius.

Confident in its technology, BYD has raised the performance warranty standard for the Blade 2 battery by 2.5 percentage points. Previously, the first-generation Blade Battery was replaced if performance dropped below 70% after eight years or 150,000 kilometers; this threshold has now been increased to 72.5%.

Having dominated the Chinese market, BYD's next focus is on international expansion. The company plans to establish production bases in key regions such as Brazil, Thailand, and Turkey to drive the global adoption of electric vehicles. Its competitive pricing, achieved through economies of scale, is seen as a significant advantage. A BYD representative stated, "As production increases, we are lowering costs and quickly narrowing the price gap with internal combustion engine vehicles. Rather than relying on subsidies, we will differentiate ourselves from other brands with our overwhelming production volume."

The share of overseas sales is also rapidly increasing. In May, BYD sold 42% (160,644 units) of its total sales (383,453 units) abroad, reflecting its transformation into a global automotive player beyond the Chinese market.

South Korea is one of the key markets BYD is targeting. Following the introduction of the cost-effective Dolphin model earlier this year, the company plans to unveil its plug-in hybrid (PHEV) technology DM-i in the country this month.

A BYD representative emphasized, "We have been supplying vehicles at lower prices in Korea compared to other countries, and we will continue to introduce various best-selling models validated in the global market to expand our influence in the Korean market."
