Overview
When a pioneering EV startup set out to deliver India’s fastest-charging battery ecosystem, their focus was on innovation, not manufacturing complexity. But as demand for their 3-wheeler EV battery packs grew, they needed a partner who could scale production without compromising quality, speed, or operational agility.

Core Customer Challenges
As volumes grew, the startup needed a partner who could take ownership of the whole build rather than one step of it:
- Diverse component sourcing
- Seamless box build integration
- Complete testing & validation
- Supply chain management
Primary Execution Priorities
As the company ramped up production for their lithium-ion battery packs for 3-wheeler EVs, they faced a familiar set of hurdles:
- Sourcing a wide range of components, from metal enclosures and thermal materials to PCBs and custom wire harnesses
- Executing a flawless box-build process, integrating mechanical, electrical, and electronic subsystems seamlessly
- Managing the end-to-end supply chain without locking up capital in excess inventory
- Ensuring every finished unit was tested, validated, and integration-ready
For a team focused on innovation and product development, getting pulled into operational firefighting was neither scalable nor strategic.
Solutions Delivered
A Comprehensive Approach
End-to-End Sourcing
We took full ownership of the BOM, sourcing every component—metal/plastic enclosures, thermal materials, wire harnesses, and PCB assemblies. This eliminated vendor-chasing for the client and ensured all parts arrived on time and in spec.
Inventory Management, Simplified
By managing warehousing and enabling just-in-time delivery, we minimized the customer’s capital tied up in stock while guaranteeing availability for uninterrupted assembly.
Turnkey Box Build Expertise
Established standard operating procedures (SOPs) for issuing material test certificates.
Implemented a centralized system to maintain and manage all test certificate documentation, ensuring complete traceability across the supply chain.
Logistics Management
With in-house mechanical, electrical, and electronic assembly capabilities, we delivered ready-to-integrate, fully tested battery packs—meeting performance and safety requirements from day one.
Key Outcome
- Operational agility
- Faster time-to-market
- Scalable manufacturing
Outcome Overview
By transferring sourcing, inventory, and assembly responsibilities to Karkhana, the EV startup was able to scale production rapidly while keeping its engineering team focused on product innovation. The result: faster launches, greater manufacturing predictability, and a competitive edge in India’s fast-evolving EV market.
