Customer Requirement

The Challenge

The company was developing a completely new lithium-ion home inverter battery using prismatic cells. Since the project was in the planning stage, the customer was looking for an experienced aluminum busbar manufacturer who could provide support both in engineering and manufacturing.

The main objectives were:

How the Client Came to Us

Adinath Enterprises was contacted by the client at the start of their project’s development. After explaining the application in question, our engineering team was able to grasp the client’s requirements as they related to the battery configuration and manufacturing operations.

Rather than offer a standard product, our company came up with project-specific engineering solutions to meet the client’s battery structure.

Engineering Consultation

Prior to the creation of the prototype, our engineering team collaborated with the customer to comprehend their battery design, analyze technical specifications, and check whether the aluminum busbars were properly prepared for laser welding and subsequent production.

Our engineering team evaluated the customer’s prismatic cell layout, current flow, electrical specifications, and battery architecture to develop an aluminium busbar solution that ensures reliable performance and efficient battery pack integration.

Examination of Provided Drawings

Our experts carefully reviewed the customer’s preliminary busbar drawings, battery assembly layout, dimensions, hole locations, manufacturing tolerances, and production feasibility to ensure accurate design validation before manufacturing.

Laser Welding Consultation

Our specialists optimized the busbar geometry, welding locations, material selection, and surface preparation to ensure consistent laser weld quality, improved electrical performance, and efficient automated battery pack assembly.

Material Selection & Optimization

Based on the application’s electrical, mechanical, and weight requirements, we selected the most suitable aluminium material to achieve optimal conductivity, weldability, structural strength, and efficient large-scale production.

Prototype Validation

After finalizing the design, Adinath Enterprises manufactured an initial batch of 20 custom aluminium busbars for prototype assembly. The customer integrated these prototypes into their battery pack and conducted comprehensive validation in their own production environment.

Validation Included
