Role - Battery Management System Architect
Location - Pune, Maharashtra
Experience - 15+ years
Role Overview:
Spiro is seeking an experienced Battery Management System (BMS) Architect to lead the design, development, and implementation of advanced Lithium-Ion Battery System architectures. The ideal candidate will have extensive expertise in BMS design, functional safety, and energy storage systems for electric vehicles (EVs) or similar applications. This role requires strong technical leadership, innovation, and collaboration skills, along with the ability to drive solutions from concept through to commercialization.
Key Responsibilities:
System Architecture Design:
- Define the overall architecture and configuration of lithium-ion battery systems based on project specifications, performance goals, and safety standards.
- Determine optimal cell chemistry, arrangement, module configuration, and pack design for energy density, power output, and efficiency.
- Explore and develop multiple cell-pack architectures such as Cell to Module to Pack, Cell to Pack, and Cell to Chassis configurations.
Cell Selection and Evaluation:
- Evaluate and select lithium-ion cell types (LFP, NCA, LMFP, Solid State) based on energy density, cycle life, safety, and application requirements.
- Collaborate with suppliers for cell performance validation, testing, and integration into battery systems.
Battery Management System (BMS):
- Architect the BMS, including hardware (sensors, controllers) and software (algorithms) for cell balancing, thermal management, and fault detection.
- Develop features for monitoring SOC, SOH, and safety protocols like overcharge protection and thermal runaway prevention.
Packaging and Integration:
- Design mechanical packaging solutions considering cooling, structural integrity, and weight distribution for seamless system integration.
- Integrate battery packs with vehicle electronics, inverters, chargers, and cooling systems.
Charging System:
- Develop architecture for charging systems, including charging ports, onboard chargers, and integration with external charging infrastructure (CCS, CHAdeMO, Type 2).
Integration with Vehicle Systems:
- Interface the battery system with vehicle systems like powertrain, vehicle control units, and infotainment systems, ensuring seamless data exchange via CAN bus, LIN bus, etc.
Safety and Compliance:
- Ensure compliance with standards (e.g., UN ECE R100, IEC 62619, ISO 26262) and integrate safety features (e.g., short-circuit protection, emergency shutdown systems) to mitigate risks.
Performance Optimization:
- Continuously optimize the performance of battery systems through simulations, testing, and validation to achieve desired energy capacity, power, and efficiency.
Cost Analysis and Optimization:
- Conduct cost analysis, optimize BOM, and collaborate with suppliers to reduce costs while maintaining performance and safety.
Collaboration and Documentation:
- Work with cross-functional teams (engineering, manufacturing, QA) to ensure alignment on technical and project timelines.
- Create comprehensive technical documentation, specifications, design guidelines, and SOPs.
Scalability and Future-Proofing:
- Design modular and scalable battery architectures to accommodate future advancements and evolving vehicle and market requirements.
Skills & Qualifications:
- Bachelor's or Masters degree in Electrical Engineering, Mechanical Engineering, Battery Technology, or a related field.
- Proven experience of 15+ years in lithium-ion battery system design and integration, preferably in automotive or energy storage industries.
- 10+ years of experience with low and high voltage (72V - 650V) lithium-ion battery systems for electric vehicles (2/3/4 wheeler, E-Bus).
- Expertise in battery architecture design, cell chemistry, BMS design, thermal management, and safety regulations (e.g., ISO 26262).
- Proficiency in CAD software (SolidWorks, AutoCAD) for mechanical design and packaging layout.
- Experience with battery testing tools (e.g., cyclers, impedance analyzers), simulation software (MATLAB, Python, COMSOL), and data analysis tools.
- Deep understanding of battery production processes, quality control, and supplier management.
- Strong problem-solving skills, attention to detail, and ability to work with cross-functional, multidisciplinary teams.
- Excellent communication and project management skills, with a proactive approach to innovation.
