NXP Semiconductors has teamed up with Elektrobit to co-develop an entry level battery management system (BMS).
The software supports NXP’s newly introduced high-voltage battery management system (HVBMS) reference design. Using Elektrobit’s Classic AUTOSAR tooling and software, the software platform of the HVBMS reference design eases the development of HVBMS architectures for electric vehicles (EVs) by abstracting the communication and controlling interactions between the BMS microcontroller and the battery cell controllers in 400V and 800V packs.

As battery packs become more powerful and complex, more sophisticated BMS architectures are needed to ensure the safety and reliability of EVs. NXP’s HVBMS RD is a scalable ASIL D architecture composed of three modules: battery management unit (BMU), cell monitoring unit (CMU) and battery junction box (BJB).
The HVBMS combines NXP’s battery cell controllers, battery junction box devices, and devices for its electrical transport protocol link (ETPL), along with production grade software drivers, to make it easier for OEMs and Tier 1 customers to develop systems.
NXP and Elektrobit have been working together for ten years, and the reference design uses Elektrobit’s EB tresos tools with NXP’s reference application software and drivers.
“Our EB tresos AutoCore is the implementation of the Classic AUTOSAR standard and our tooling environment, called EB tresos Studio, is used to configure these basic software modules with NXP’s software modules,” said Michael Robertson, Vice President, Head of Strategy & Product Management, Elektrobit.
“Elektrobit will additionally offer support to customers that use NXPs HVBMS platform when configuring and integrating EB tresos AutoCore into their environment, and will continue working with NXP in the second development phase of the HVBMS reference design software.”
“NXP and Elektrobit have complementary competencies,” said Dr. Andreas Schlapka, Director & Segment Manager Battery Management Systems, NXP. “NXP has extensive knowledge in BMS, with a scalable portfolio of analog and digital silicon devices to support the full variety of BMS architectures. Elektrobit, on the other hand, has in-depth knowledge of the software architectures that are used in the automotive domain and AUTOSAR expertise. Bringing these two competencies together is key, which is why NXP selected Elektrobit to join forces to co-develop the software platform for the HVBMS reference design.”
