NXP Semiconductors has joined forces with Elektrobit 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.
As demand for battery-powered cars (EVs) continues to increase, so does the demand for improved performance, faster charging time, increased range and battery life, and improved safety. These demands drive rapid technological advancements in EV battery designs, especially for high voltages like 400V or 800V.
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.
Utilizing Elektrobit’s EB tresos (AutoCore, AutoCore OS, and RTE), NXP’s reference application software and Complex Device Drivers (CDDs) are designed and integrated into NXP’s HVBMS RD.
