15 AKM 46 POC

Product catalog summary

Certification and Standards:
The document outlines that the product is certified according to railway and automotive standards, specifically developed according to ISO 26262 up to ASIL C and EN 61508 SIL 2. It has been tested for safety under various standards including USABC, IEC, SAE, EN 50657, EN 50129, and UN 38.3. The system features multi-level short circuit protection and a redundant battery management system for enhanced operational safety.

System Features:
The system is suitable for multi-string configurations with monitoring capabilities at both single-string and full system levels. It offers protection classes ranging from IP67 to IP6K9K and includes a robust control unit BMS master compatible with SIL2 hardware. The system also provides SOC (State of Charge) and SOH (State of Health) analysis, along with single cell voltage monitoring and balancing.

Performance and Design:
The product is described as scalable, validated, and durable, with high energy and performance density. It is designed for easy system connectivity and is ready-to-install with standardized CAN bus and optional VDA/SAE cooling connections. The system boasts a good price-performance ratio due to its development for serial production, and features liquid cooling for even temperature distribution, contributing to its compact and lightweight design.
