On the 6th, Auto Silicon Co., Ltd. announced that two types of its self-developed battery management chipsets for electric vehicles, ‘BMIC (Battery Management Integrated Circuit)’, have received ASIL-D product certification according to international functional safety standards from Germany’s T?V Rheinland.

The chipsets are characterized by advanced functional safety concepts, precise battery cell voltage measurement, high-speed communication, and component reduction effects in battery management systems.

The BMIC chipsets were developed over a total period of about three years. Auto Silicon, SK On, and T?V Rheinland jointly participated throughout the entire development process?from product planning to design, verification, and reliability testing?to create and implement the ASIL-D concept applicable in the global market. It is known that the product development applied a series of procedures and safety analysis requirements mandated by ISO 26262.

Subsequently, the international certification body T?V Rheinland conducted a ‘Functional Safety Assessment’ on the two chipsets over a period of one year and eight months, resulting in ASIL-D certification. Additionally, 70% of the chipset development personnel obtained T?V Rheinland’s international functional safety engineer and manager professional certifications during the development process.

Joo Jae-man, system development manager at SK On, stated, “The BMIC battery management chip is a product recognized for its high level of quality and stability,” adding, “Through this chip, we expect to dramatically improve the performance of battery management systems across all areas including battery cells, modules, and packs.”

Manuel Diez, Global Head of Functional Safety at T?V Rheinland, said, “Through this ASIL-D product certification, Auto Silicon has shown the direction that core chipsets in the battery sensing market?a fundamental part of the rapidly growing battery management system sector in the automotive world?should take.”

Meanwhile, this product, which began mass production in September this year, is scheduled to be exclusively supplied to SK On for a certain period. Furthermore, Auto Silicon is promoting the product to multiple electric vehicle, battery pack, and ESS manufacturers in addition to SK On.
