BYD Motor Indonesia President Director Eagle Zhao confirmed in Jakarta, recently, that the company's second-generation blade battery will be produced at its facility in Subang, West Java.

Responding to questions about local battery production and Flash Charging technology, he also said that BYD is considering the local assembly of most of its vehicle line-up and is open to partnerships with other businesses to expand its battery operations.

"The second-generation blade battery will be produced at the BYD Subang factory. BYD is very open to collaboration with business corporations," Eagle said.

BYD has not disclosed when local production of the second-generation blade battery will begin, its planned production capacity or details of potential partnerships with other electric vehicle manufacturers.

Eagle also said that the company intends to manufacture most of its vehicle models locally, including the BYD Atto 2, as part of its strategy for the Indonesian market.

The second-generation blade battery will be introduced in various BYD models in Indonesia, starting with the M6. Eagle also confirmed that the Atto 2 would receive the technology. The Denza New D9 and Z9GT are among the models that already use the battery and its associated charging technology. BYD's Subang plant currently produces the Atto 1, the M6 in both plug-in hybrid electric vehicle (PHEV) and battery electric vehicle (EV) variants, and the New D9.

Charging speed and energy density

BYD developed the second-generation blade battery over six years of research. According to the company, its energy density is 5% higher than that of the previous generation. Its Flash Charging technology enables the battery to be charged from 10% to 70% in five minutes.

FlashPass technology is designed to facilitate ion movement within the battery cells to support faster charging. BYD has also optimised the cathode, electrolyte and anode to reduce internal resistance and control heat generation during charging. In addition, the company has developed a Solid Electrolyte Interphase (SEI) layer to maintain the battery's chemical stability.

Battery safety tests

BYD states that the second-generation blade battery passed a test combining flash charging with a nail-penetration test. According to the company, the tests did not trigger thermal runaway, smoke or fire, even after 500 Flash charge cycles.

The company also states that the battery passed forced short-circuit testing involving four cells simultaneously without fire or explosion, despite temperatures exceeding 700 degrees Celsius. The planned local production of the second-generation blade battery and the potential local assembly of additional vehicle models form part of BYD's manufacturing plans in Indonesia. The company is also considering partnerships with other businesses to expand its battery operations.
