Case Study · System Architecture
Development of a modular low-voltage battery system for emerging markets - academically validated and published at SAE International (Paper 2019-26-0032).
Electrification in markets such as India often struggles with harsh environmental conditions, missing charging infrastructure and high price sensitivity. Conventional fixed high-voltage systems are frequently oversized and economically hard to justify.
The goal was a system that is cost-efficient while remaining technically flexible enough to cover very different vehicle segments.
A 48V base module with "swappable" and "stackable" architecture for rapid exchange operations and flexible capacity scaling.
System sizing based on real driving profiles and specific environmental stress factors for robust operation.
Hybrid concept combining passive and active cooling depending on performance demand in low- and high-power use cases.
Optimization of mechanical and electrical layouts to ensure serviceability, scalable deployment and local supply chains.
The result is a robust standard architecture that enables highly different configurations without compromising safety or efficiency. The swapping approach effectively bypasses the challenge of missing charging infrastructure.
