Excelher Advanced Powertrain

Transport is at the core of modern society. Imagine using your expertise to shape sustainable transport and infrastructure solutions for the future? If you seek to make a difference on a global scale, working with next-gen technologies and the sharpest collaborative teams, then we could be a perfect match.

About the Role:

We are seeking a passionate and technically curious ExcelHer to join our Advanced Powertrain and Electrification Division. The focus of this internship is to assist in the development, testing, and optimization of battery energy transfer systems between electric trucks and electric construction equipment (such as loaders, diggers, and cranes). This includes both static and dynamic charging concepts, bi-directional energy flow, and smart load balancing strategies.

Key Responsibilities:

• Support the design and modeling of battery-to-battery (B2B) energy transfer systems across heavy-duty electric platforms.
• Assist in the integration of vehicle-to-vehicle (V2V) and vehicle-to-equipment (V2E) energy systems using DC fast-charging standards and high-voltage safety protocols.
• Participate in simulation and prototyping of energy management systems (EMS) for intelligent energy routing and load sharing.
• Contribute to the development of real-time monitoring and control systems, including CAN communication and BMS interoperability.
• Assist with lab and field testing, collecting and analyzing performance data from trucks and equipment under real-world duty cycles.
• Research global standards (e.g., ISO 15118, CHAdeMO, CCS, SAE J1772) applicable to construction and transport electrification.
• Collaborate with electrical engineers, firmware developers, and systems architects to iterate and improve system reliability and efficiency.
• Document progress, test results, and technical learnings in structured formats for internal knowledge and IP development.

Preferred Qualifications:

• Pursuing or recently completed a Bachelor’s/Master’s in Electrical Engineering, Power Electronics, electronics, or a related field.
• Basic understanding of Li-ion battery systems, BMS, DC charging protocols, and power electronics.
• Hands-on experience with MATLAB/Simulink, LTspice, Python, or similar simulation and prototyping tools.
• Familiarity with CAN bus, data logging, and diagnostic tools for electric vehicle platforms.
• Passionate about sustainability, renewable energy, and electric mobility solutions.
• Excellent communication, problem-solving, and collaboration skills.

Bonus Skills (Nice to Have):

• Exposure to construction machinery electrification trends.
• Knowledge of thermal management and SOH/SOC estimation algorithms.
• Experience working with prototype builds, hardware integration, or test benches.

What You’ll Gain:

• First-hand experience working on cutting-edge energy transfer technologies for next-generation electric fleets.
• Cross-domain exposure: mobility, construction, energy storage, and power electronics.
• Opportunity to work in a fast-paced R&D environment with mentorship from experienced engineers.
• Potential pathway to full-time employment based on performance and project success.
