NXP Semiconductors has partnered with Elektobit to co-develop the software platform that supports NXP’s newly introduced high-voltage battery management system (HVBMS) reference design.  

Using Elektrobit’s Classic AUTOSAR tooling and software, the new 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. 

Elektrobit has been collaborating with NXP for more than ten years. Elektobit is a leader in embedded and connected software products and services for the automotive industry. 

“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.” 

As the demand for electric vehicles continue, so does the demand for improved performance, faster charging time, increased range and battery life, and improved safety. 

As these batteries 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).  

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.
