NXP and Elektrobit have agreed to jointly develop software for next-generation automotive battery management systems. The solutions will reduce the entry-level cost of battery management system (BMS) development and enhance ease-of-use of NXP’s high-voltage BMS reference design (HVBMS RD).
Improved performance, faster charging time, increased range and battery life, and improved safety are seen as crucial in the adoption of electric vehicles (EVs), where high voltages of 400V or 800V are needed.
NXP’s HVBMS RD is a scaleable ASIL D architecture composed of three modules: battery management unit (BMU), cell monitoring unit (CMU) and battery junction box (BJB). NXP’s wide portfolio of battery cell controllers, battery junction box devices, and devices for its electrical transport protocol link (ETPL), along with production grade software drivers for these silicon devices, makes it easier for OEMs and Tier 1 customers to enter the growing market of HVBMS and enables them to focus effort on their unique application features.
“NXP and Elektrobit have complementary competencies,” explained 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.”
With Elektrobit’s EB tresos (AutoCore, AutoCore OS, and RTE), NXP’s reference application software and Complex Device Drivers (CDDs) will be designed and integrated into NXP’s HVBMS RD.
“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.”
