New Energy Battery Management System Solution

The Battery Management System (BMS) is a key component of electric vehicles, mainly responsible for monitoring the operating status of the power battery, implementing charge and discharge control, thermal management, and energy balancing functions. Through the CAN bus, the BMS communicates efficiently with the vehicle controller, intelligent charger, instrument cluster, and other devices, ensuring the safety, reliability,and efficient operation of the entire battery system.

Scheme Introduction

● This BMS solution is implemented based on C*Core's MCUs. Multiple MCU models such as CCFC2007PT, CCFC2016BC, CCFC2017BC, and CCFC3008PC/PT, can meet the diverse requirements of different BMS of vehicle models. For example, The cost-optimized high-voltage BMS solution can be implemented with MCU-CCFC3008PC.

Full-stack Security:MCU, MCAL, and functional safety libraries have achieved functional safety of ASIL-D;Comply with the EVITA-Full security specification.

Autonomous Core:PowerPC architecture, with computing power reaching up to 700 DMPIS, single-core can perform cell monitoring, current sensing, battery status calculation, and fault protection.

Memory Resources:Built-in 4MB/3MB Flash, 576KB/320KB RAM, supports hardware A/B SWAP, and OTAupdates.

Rich Communication Interfaces and Peripherals:Integrated with 8x CAN FD, 12x LIN, 8x DSPI, 1x GTM4.1, 2x CCU7, and 4x ADC(total 37 channels).
