CAIT-SH's CIIC and PDC Pass ASIL D Functional Safety Assessment

Recently, CIIC medium platform (CIIC-M) and intelligent low-voltage power distribution controller (PDC) launched by Contemporary Amperex Intelligence Technology (Shanghai) Limited (CAIT-SH) have successfully passed an ASIL D functional safety assessment conducted by exida, an independent third-party testing and certification agency.

CAIT-SH's CATL integrated intelligent chassis (CIIC) achieves high-efficiency integration and fusion of vehicle control, battery management, low-voltage power distribution, driving, steering, braking, and other systems. With its prominent features of upper and lower decoupling, high-level integration, and open architecture, the CIIC allows partners to conserve R&D resources while offering optimum user experience and unlocking application-specific value. As the intelligent management center for the vehicle's low-voltage energy, the PDC utilizes novel E-Fuses to replace traditional fuses. Besides supplying low-voltage power to all components, it promptly isolates faults in the event of overload or short circuits, ensuring the stability of the vehicle's low-voltage power supply system and passenger safety.

In the assessment of the CIIC-M and PDC, exida applied different strategies considering their respective characteristics. Given the CIIC's high degree of integration, its assessment focused on ISO 26262 parts 2, 3, 4, and 8, focusing on conformity in the conceptual development phase, system confirmation, safety management, and support processes. The PDC's assessment focused on ISO 26262 parts 2, 4, 5, 6, 7, and 8, checking conformity of the system, hardware and software development, safety management, production services, and support processes.

ISO 26262 is an internationally recognized automotive functional safety standard and a crucial entry point for automotive EE component suppliers around the world. The successful ASIL D assessment of CAIT-SH's CIIC and PDC under ISO 26262 signifies that these products meet the standard's highest requirements, representing a recognition of CAIT-SH's technological capabilities in producing high-safety, high-reliability products by an authoritative international organization.

CAIT-SH has always made safety a top priority in its product development to empower partners with high-safety technology and works with them to provide robust safety assurance for users.
