Located in the city’s Bishan District, the factory is currently the only production base for the Blade Battery. It possesses a highly demanding production environment and much of BYD's self-developed Blade Battery production equipment. The factory has a total investment of 10 billion yuan with an annual production capacity of 20GWH.
They serve asf the bedrock for efficient and stable production, in turn forming the backbone of the Blade Battery’s quality. The Blade Battery refers to a single-cell battery with a length of 96 cm, a width of 9 cm and a height of 1.35 cm, which can be placed in an array and inserted into a battery pack like a blade.
In addition to solving the issue of endurance – once a previous limiter to the development of traditional lithium iron phosphate batteries – the Blade Battery can be charged from 10% to 80% of its full capacity within 33 minutes, supporting the BYD Han EV's acceleration of zero to 100 km/h in 3.9 seconds.
According to Sun Huajun, the Vice General Manager of FinDreams Battery, these demanding conditions are a “necessary foundation” to the Blade Battery’s high safety standards. “The nearly one-meter-long pole piece can achieve tolerances of within ±0.3mm, and the accuracy and speed of a single-piece lamination have an efficiency of 0.3s/pcs.
