Renesas rolls out complex device driver software to facilitate development of battery management systems for electric vehicles | national business

Tokyo, Japan – (BUSINESS WIRE) – June 2, 2022 –

Renesas Electronics Corporation (TSE: 6723), a leading supplier of advanced semiconductor solutions, today introduced its AUTOSAR-compliant complex device driver module to designers of automotive battery management systems (BMS) in electric vehicles (EVs). New software pairs with industry leader Renesas ISL78714 Li-ion Battery Management IC To accelerate design and improve performance of next-generation systems.

CDD software is designed to work with Renesas winning combination BMS reference design kit, which includes ISL78714 IC and RH850/P1M MCU. The CDD includes the configuration and integration of Renesas required Micro Controller Abstraction Layer (MCAL) modules for the RH850 MCU. It provides a complete low-level software solution for collecting measurements of battery cell voltage and temperature and controlling the cell balancing functions of the ISL78714. Configurable parameters define the number of cells in the BMS system and the rate required to collect battery cell data.

CDD software has a simple but full-featured API that allows the end user application software to receive real-time battery cell measurements. The software and protocol management interfaces needed to run the ISL78714 are built into the CDD software and run on top of the existing lower-level SPI, GPIO, and General Purpose Timer (GPT) drivers built into the MCAL modules. CDD software provides clients with a practical structure to simplify the design of their software and allows them to focus efforts on their unique application features.

The new ISL78714 CDD program follows the development processes of ISO26262 ASIL D (Highest Standard Vehicle Functional Safety). The RH850/P1M MCUs and MCALs also achieve ASIL D. The ISL78714 CDD software, as a model for successful ASIL D software development, is a formidable asset. Customers who wish to assist with their design can work under contract with Renesas Partner Tata Elxsi to develop their system.

“As the electric vehicle market continues to expand rapidly, battery management is a critical component of the success of new vehicles,” he said. Niall Lin, Vice President of Automotive Analog Power and Video Business at Renesas. “The Renesas ISL78714 IC software combined with our new CDD software helps our customers get the best possible performance out of their battery management systems, reduces the development schedule, while easing the challenging process of meeting ASIL D’s stringent safety requirements.”

“The unique features of the Renesas ISL78714 IC for battery management, along with the new CDD software, provide a powerful platform for developing our integrated building management systems,” said Chris Klesick, Vice President, Battery Management for Our Next Energy. “This technology partnership is foundational to ONE’s immediate needs for BMS and provides a path for future improvements.”
