EOL Test Station for Pilot/Production/After-Sales Lines

OVERVIEW

Originating from battery performance testing, Nebula has evolved into a leading provider of end-of-line (EOL) testing systems that seamlessly integrate into battery manufacturing lines. With deep expertise in both testing methodology and automation engineering, Nebula empowers OEMs and battery manufacturers to ensure product quality, process consistency, and production efficiency.
Having delivered numerous large-scale testing, assembly and remanufacturing solutions across pilot lines, mass production lines, and after-sales testing lines, Nebula understands the unique requirements of each stage of battery assembly and remanufacturing. Our systems are tailored to the specific characteristics of cell, module, and pack configurations—including high-voltage safety, signal integrity, and thermal behavior—to guarantee accurate results and minimize false negatives.
Backed by years of hands-on project experience and in-depth knowledge of battery system design, Nebula’s EOL test solutions not only validate performance, but also enable manufacturers to fine-tune their processes, improve yield, and accelerate the time-to-market for next-generation energy storage products.

FEATURES

1.Deep Understanding of EOL Requirements & Comprehensive Test Coverage

With years of experience across diverse battery manufacturing projects, Nebula delivers fully customized EOL test systems precisely aligned with each client's process specifications. We've internally defined 38 critical EOL test items to cover all key performance and safety metrics, including both dynamic and static testing when integrated with Nebula cyclers. This ensures end-product quality and minimizes risks before shipment.

2.Flexible, Robust Software Platform with MES Integration

Nebula’s software architecture is designed for full interoperability. Our system can be seamlessly integrated with third-party software engines and configured to match specific user interface or data visualization requirements. Built-in MES connectivity and modular coding ensure smooth deployment across different production environments and customer IT frameworks.

3.Industrial-Grade Stability with Custom Fixtures & Reliable Supply Chain

We leverage our in-house design capabilities and mature supplier ecosystem to deliver customized test fixtures, harnesses, and safety enclosures—ensuring high mechanical precision and stable performance over continuous 24/7 operation. Each fixture is tailored to the customer's specific cell, module, or pack architecture, supporting everything from pilot runs to full-scale production.

4. Exceptionally Fast Turnaround Time

Thanks to Nebula’s deep project expertise, agile engineering team, and well-orchestrated supply chain, we consistently deliver fully operational EOL test stations within just a few months. This accelerated lead time supports customers’ ramp-up schedules and helps them bring products to market faster without compromising testing depth or reliability.
