End-to-End Battery System Capability
Jayem provides complete battery system development, from concept to commercialization.
Battery Pack Design & Engineering
Battery pack architecture is designed to meet electrical, mechanical, thermal, and safety requirements. System design focuses on packaging efficiency, structural integrity, thermal management, and serviceability ensuring seamless integration with the vehicle platform.
Battery Management System Integration
Battery systems are integrated with automotive-grade BMS architectures, supporting cell monitoring, thermal control, safety logic, and vehicle communication. Integration is carried out to ensure stable performance across operating conditions and long service life.
Manufacturing & Assembly
Battery packs are manufactured through controlled, scalable production processes, supporting prototype builds, pilot production, and series manufacturing. Assembly processes are defined to ensure consistency, traceability, and quality across volumes.
Testing, Validation & Certification
Battery systems undergo functional, safety, and performance validation to meet automotive standards. Testing supports homologation readiness, durability validation, and production release. Automotive battery packs are developed to meet AIS and ARAI certification requirements.
Scalable & Customisable Platforms
Jayem battery systems are developed using a modular platform approach that enables efficient creation of multiple voltage and energy configurations. This approach supports faster customisation, shorter development timelines, reuse of validated platforms across programs, and a smooth transition from pilot builds to production. Depending on program scope and complexity, custom battery pack development is typically completed within six to nine months.
