• Compare and analyze core indicators such as performance, reliability, cost, and adaptability to identify internal technical gaps and optimization directions, driving the iterative upgrade of the company’s battery solutions.
• Based on competitor technology research findings and the company’s business need, participate in the planning and design of battery pack system solutions for construction machinery/commercial vehicles, and lead key technology selection, architecture definition, and technical route formulation.
• Provide technical support throughout the entire battery pack development process, including requirements analysis, solution reviews, key technical problem-solving, and validation strategy formulation.
• Ensure the technical feasibility, cost competitiveness, and scenario adaptability of the solutions.
• Combine industry benchmark technologies with the company’s product pain points to deliver actionable technical optimization recommendations.
• Drive the achievement of key goals such as improved thermal management efficiency, optimized structural integration, cost reduction, and enhanced reliability.
• Develop and accumulate methodologies and case libraries for competitor analysis, technology benchmarking, and solution optimization.
• Promote internal knowledge sharing and reuse to build the team’s core technical competitiveness.
• Participate in cross-departmental technical reviews and project communications, providing professional technical assessment opinions.
• Facilitate collaboration between design, BMS, validation, and process teams to implement innovative technical solutions.

Requirements

• Bachelor’s degree or above in Electrical Engineering, Vehicle Engineering, Electrochemistry, Mechanical Engineering, Power Engineering and Engineering Thermophysics, or related fields.
• 8+ years of relevant working experience in the power battery industry; candidates with practical experience in battery solution design, type selection evaluation, competitor analysis, or electrification projects for commercial vehicles/construction machinery are preferred.
• Familiar with battery system technologies for passenger vehicles, commercial vehicles, and construction machinery; have full-process experience in battery solution selection, in-depth competitor analysis, or project implementation.
• Candidates who have led the selection and implementation of battery solutions for at least 3 complete vehicle electrification projects are preferred.
• Proficient in core technologies of power battery systems; familiar with cell types, performance parameters and applicable scenarios; master mainstream technical routes in battery pack system architecture, thermal management, structural design, and core BMS logic.
• Possess strong in-depth competitor analysis capabilities, capable of independently completing competitor analysis, technical assessment, cost analysis and value extraction; proficient in using data analysis and benchmarking tools to deliver professional reports.
• Familiar with domestic and international power battery-related standards (such as ISO 26262, IEC 62660, UN 38.3, etc.) and compliance requirements for construction machinery electrification; understand the battery supply chain system and cost structure.
• Have solid solution design and optimization capabilities, able to deliver technically feasible and cost-competitive battery system solutions based on competitor research and business needs.
