Position: Battery Design Engineer

Job Location: Surat, Gujarat

Company: Vsole Solar Energy Private Limited

Roles & responsibilities:

Design and develop conceptual 3D models of Li-ion battery packs/modules for ESS, EV, and BESS applications using CAD software.

Prepare and review supplier drawings for components (cells, busbars, enclosures, connectors, thermal management parts, etc.), ensuring design intent and specifications are met.

Prepare and maintain detailed Bill of Materials (BOM) for battery packs, including component specifications, quantities, and supplier references.

Create detailed assembly drawings for complete battery pack systems, ensuring manufacturability and compliance with design standards.

Develop sub-assembly drawings for individual modules, racks, BMS integration, wiring harnesses, and mechanical structures.

Prepare and maintain production documents, including assembly process sheets, quality checklists, and mechanical testing protocols.

Collaborate with electrical/BMS teams to ensure mechanical design compatibility with battery management systems and safety requirements.

Support design validation through prototyping, testing, and analysis (thermal, structural, vibration, etc.).

Ensure designs comply with relevant safety and certification standards (UN38.3, IEC 62133, IEC 62619, AIS 156, IS 16046, etc.).

Coordinate with suppliers and vendors for component sourcing, drawing approvals, and design modifications.

Support troubleshooting and design improvements based on field feedback and failure analysis.

Maintain design documentation, revision control, and engineering change management (ECN/ECR processes).

Education & Experience:





Bachelor's/Master's degree in Mechanical Engineering, Electrical Engineering, Mechatronics, or related field.

1+ years of experience in battery pack design, preferably in Li-ion battery systems for ESS, EV, or BESS applications.

Proficiency in 3D CAD tools (SolidWorks, Creo, CATIA, or similar).

Strong understanding of battery pack architecture — cells, modules, BMS integration, thermal management, and mechanical enclosures.

Experience in preparing BOMs, assembly drawings, sub-assembly drawings, and production documentation.

Familiarity with GD&T; (Geometric Dimensioning & Tolerancing) and drawing standards (ASME/ISO).

Knowledge of battery safety standards and certifications (UN38.3, IEC +91-XXXXXXXXXX, IS 16046, AIS 156) is a plus.

Understanding of DFM (Design for Manufacturability) and DFA (Design for Assembly) principles.

Strong analytical and problem-solving skills with attention to detail.

Good communication skills to coordinate with suppliers, cross-functional teams, and manufacturing units.

Prior experience working with Li-ion battery manufacturers or EV/ESS/BESS OEMs. Exposure to thermal simulation, structural analysis (FEA), or vibration testing of battery packs. Familiarity with PLM/PDM tools for documentation and revision control.
