JBM Auto Advances Lightweight Bus Technology and Battery Efficiency

JBM Auto Expands Lightweight Bus Construction Technologies

JBM Auto has partnered with bus body builders Malaysia-based GML and Egypt-based Geyushi to adopt lightweight construction technologies, according to its annual report. The company has also integrated machines with cloud-based monitoring capabilities to track efficiency and performance in real time. These systems are intended to help reduce specific energy consumption across operations. JBM Auto is additionally using cloud-based tools for utility optimization, with particular attention to cooling tower operations. The approach is designed to improve energy performance while providing greater visibility into operating conditions and resource utilization. These initiatives form part of the company's broader effort to improve manufacturing efficiency and reduce vehicle weight without compromising required performance and safety standards.

Advanced Battery Development Targets Extreme Climate Conditions

JBM Auto has adapted Gen3 technology for 24-hour uptime by improving thermal management and developing advanced batteries that use alternate cell-cooling methods. The work is intended to address the demands of extreme Indian climates while supporting fast charging. The company is also working with suppliers to meet Level-1 compliance requirements, with Level-2 compliance planned after Level-1 requirements are achieved. Battery development has included improvements in materials, charging algorithms and battery management systems. According to the annual report, these improvements have increased charge-cycle efficiency and extended the life of lithium-ion batteries. Together, the thermal-management, cooling and battery-management efforts are focused on improving reliability, charging performance and operating durability under demanding conditions.

Multi-Material Bus Structures Aim to Reduce Weight

JBM Auto currently uses Advanced High-Strength Steel (AHSS) in bus structures, while aluminum bodies are used for exports to reduce weight while meeting safety and crash standards. The company plans to move toward multi-material architectures that combine AHSS, aluminum, stainless steel and engineered composites. This approach is intended to achieve further weight reduction while maintaining structural requirements. JBM Auto also plans to incorporate sustainable interior materials as part of this development direction. Lower vehicle weight can support improved energy efficiency and potentially allow greater passenger capacity within the required vehicle architecture. The planned combination of materials therefore represents a broader structural strategy focused on balancing weight, durability, safety, energy performance and passenger-carrying capability.

Robotic Welding and Process Optimization Improve Productivity

JBM Auto has converted manual welding operations to robotic welding and has undertaken OBAYA and VAVE projects to improve manufacturing performance. These initiatives have helped raise productivity while reducing waste across production activities. The use of robotics enables greater consistency in welding operations and supports the company's broader manufacturing-efficiency objectives. At the same time, OBAYA and VAVE projects provide additional mechanisms for identifying opportunities to improve processes and reduce unnecessary resource use. Combined with cloud-based machine and utility monitoring, these manufacturing measures demonstrate a wider shift toward technology-enabled production. The company's focus is not limited to vehicle structure development; it also encompasses factory operations, process efficiency and resource utilization as part of its efforts to improve overall production performance.

R&D Investment Supports Technology Development

JBM Auto's technology initiatives are supported by increased investment in research and development. The company's R&D spending rose to INR 867.3 million in FY 2025–26, providing resources for work across battery technology, vehicle structures, thermal management, manufacturing processes and energy efficiency. The development program covers improvements ranging from battery materials and charging algorithms to battery management systems and alternate cell-cooling methods. It also includes the planned adoption of multi-material architectures and sustainable interior materials. These activities indicate that JBM Auto is pursuing technology development across both vehicle and manufacturing systems rather than focusing on a single component. The combination of higher R&D spending and ongoing engineering initiatives supports its efforts to improve vehicle efficiency, durability, productivity and passenger capacity.
