Battery packs are the heart of every electric vehicle (EV)—they supply the power that drives the entire system. Just like a heart, if a battery pack is assembled incorrectly, the consequences can be life-threatening—not only for the workers on the line but also for the drivers and passengers relying on the vehicle's safety and reliability.
A key to minimizing these risks lies in the use of Real-Time Location Systems (RTLS). By controlling & guiding the assembly in real time, RTLS technology helps ensure that each step of the process is carried out with exactness, drastically reducing the likelihood of assembly errors that could lead to electrical failures, thermal events, or structural issues.
Challenges in battery pack assembly
In the rapidly evolving landscape of EV manufacturing, battery pack assembly has become increasingly complex. The growing size of battery packs makes it difficult to accurately locate tightening points, particularly when the operator’s line of sight is obstructed. At the same time, the sheer number of screws involved requires meticulous control and sequencing—any missed or improperly tightened fastener can pose a major safety hazard.
Moreover, modern production environments are often dynamic. Many manufacturers use Automated Guided Vehicles (AGVs) or Continuous Flow Lines (CFLs), where components are constantly in motion. This movement makes it challenging to maintain consistent positional accuracy throughout the process, increasing the risk of assembly errors if not properly managed.
How RTLS enhances battery pack assembly
Implementing an RTLS like nexonar addresses these challenges by providing precise, real-time tracking of tools, components, and worker movements. Key benefits include:
- Accurate tool positioning: nexonar's millimeter-level tracking ensures that tools are correctly positioned for each fastening point, even on large battery packs, reducing the risk of misalignment.
- Error prevention: The system guides operators through the assembly sequence, verifying each step in real-time to prevent missed or improperly tightened screws, thereby enhancing safety and reliability.
- Adaptability to moving lines: nexonar continuously monitors and adjusts for positional changes in moving assembly lines, ensuring consistent accuracy despite shifts inherent in AGV or CFL setups.

- Enhanced safety and quality control: By ensuring each fastening is performed correctly, nexonar reduces the risk of defects that could lead to safety hazards, thereby improving overall product quality and reliability.
Real-World Impact
Manufacturers using nexonar report measurable improvements in key areas. Operator safety is significantly enhanced, as the system ensures that each screw is properly secured, minimizing risks like short circuits or thermal runaway. Assembly processes become more efficient thanks to real-time feedback and fewer errors, reducing cycle times and improving throughput.
Additionally, nexonar’s built-in tracking and documentation provide complete traceability for every assembly step. This supports both internal quality management and compliance with external standards, giving manufacturers greater confidence in their production output.
As EV manufacturers work to meet the growing demand for safe, high-performance electric vehicles, optimizing battery pack assembly is more critical than ever. A single error can compromise the safety of an entire system—but with nexonar’s RTLS, manufacturers gain the tools to prevent mistakes, ensure quality, and enhance safety at every step.
By integrating nexonar into the battery assembly process, companies can raise their standards for quality, safety, and productivity—all while gaining the traceability and control modern manufacturing demands.
