EV embedded software for electrical powertrain systems

The shift towards electrification in the transportation industry creates new challenges for engineers and software architects designing safe, secure, and hassle-free electrical powertrain systems. The sheer complexity of EV-embedded software requires purpose-built solutions to address the challenges faced during development.

Current electric vehicle trends

Current electric vehicle trends are becoming increasingly popular as consumer demand for sustainable transportation rises, governments offer incentives to own EVs, and technology improves EV range and charge speed.

The result is a booming EV market expected to make up more than half of all passenger vehicles globally by 2040. Auto manufacturers have announced and released hundreds of new models, and EV infrastructure is expanding worldwide.

Components of an EV powertrain system

EV powertrain systems are complex systems that rely on various embedded software to operate. Newer EV models feature greater integration across all EV powertrain system components, which can improve performance and efficiency but also make the system more complex. While the system's complexity increases, the embedded software must be able to handle that complexity, ensure safe operation, protect the system from cyberattacks, and deliver high performance.

The battery management system is one of the key ECU functions in EVs

The number of challenges for embedded software engineers is increasing as EVs become more complex and trend towards integration. Engineers must manage combo-box architecture issues, network-based security threats, and evolving ASIL requirements.

Despite these challenges, there are many opportunities for embedded software engineers in the EV industry. Siemens Capital Embedded can help engineers overcome these challenges with an integrated electrical/electronic (E/E) systems development approach.

An integrated approach to embedded system development

Capital Embedded's integrated approach to embedded system development addresses the critical challenges of embedded software design for EVs. It supports both arms of the multi-domain system model and integrates into multiple domains such as MCAD, PLM, and ALM systems to deliver truly integrated system development. That integration enables software distribution and provides layered embedded security for ECUs in connected vehicles.
