With a focus on low carbon footprint and sustainability, Electric vehicles (EVs) are becoming increasingly popular due to their numerous benefits. Electric vehicles (EVs) are environmentally friendly, have lower running costs, and offer the potential for long-term cost savings for consumers. They offer a cleaner alternative to traditional gasoline-powered cars, contributing to reduced greenhouse gas emissions and improved air quality which is of great importance in a city like New Delhi, India. Many cities in India struggle with pollution throughout the year, and EVs that run on Li-ion batteries can help alleviate this issue, boosting air quality and providing a cleaner commuting experience on city roads. However, manufacturers face several challenges in the EV battery supply chain, ranging from tracking critical raw materials to managing complex production workflows. Lack of visibility, traceability, and real-time data can significantly hamper productivity and quality.
The EU, the UK, the USA, and China are leading the way when it comes to manufacturing EV batteries and EVs where brands like Nissan, Ford, Tesla, BMW, BYD, etc. are some of the popular electric vehicle manufacturing automakers. To stay competitive and sustainable, Indian manufacturers too must embrace smart technologies like RFID (Radio Frequency Identification) and IoT.
Let’s see how modern technologies like RFID and IoT can help with streamlining procurement, ensuring inventory visibility, and boosting the production of EV batteries and electric vehicles.
1. RFID is Powering Up EV Battery Supply Chains
In EV manufacturing, supply chain transparency is critical to all businesses involved. RFID-based solutions bring real-time visibility to battery component sourcing, shipping, and receiving processes. Every Li-ion cell or module can be tagged with RFID labels that store critical metadata, from origin and chemistry to shipping history and storage conditions.
RFID thus ensures that manufacturers can trace parts back to their source instantly, manage inventory dynamically, and prevent counterfeits from entering the supply chain. With RFID gate systems installed at docks and storage areas, materials can be automatically logged as they arrive or leave, eliminating manual errors and boosting inbound/outbound logistics efficiency.
2. Intelligent Labels for Li-ion Batteries
RFID-enabled smart labels offer more than identification; they are data carriers. These labels can withstand high temperatures and chemical exposure, ideal for battery manufacturing environments. We offer some of the best RFID tags and labels that are designed to meet identification and data-capturing needs in harsh environments such as battery and EV manufacturing. You can place an order for these premium RFID labels here.
Embedded with EPC (Electronic Product Code) on UHF RFID chips, these labels allow tracking of battery lifecycle events, throughout the cell assembly to module integration and pack testing.
Zebra’s thermal transfer RFID labels with inlays like ZBR2000 are a good example. They’re designed to bond well with hard-to-label surfaces such as metal battery casings and offer long-term durability. These RFID labels enable compliance with evolving battery traceability regulations in the EU and other regions.
3. Tracking EV Parts with RFID
Beyond batteries, EVs consist of thousands of components, from electric motors to embedded electronics. RFID solutions help track every critical part during vehicle assembly. As parts move along the production line, fixed RFID readers like the Zebra FX9600 and AN480 RFID antennas capture data from tagged components to ensure correct sequencing, eliminate mix-ups, and reduce production halts.
Additionally, automakers can trigger alerts if the wrong part enters a process station or if a high-value component is missing by integrating RFID with MES (Manufacturing Execution Systems). Such a level of automation minimizes human error and accelerates production cycles which is essential in the fast-paced EV industry.

4. Ensuring Quality Control in EV Manufacturing with RFID Technology
RFID facilitates end-to-end traceability that supports stringent quality assurance protocols. Each RFID-tagged component or battery can be linked to test results, calibration records, and process parameters. If a defect is detected in the final vehicle, the manufacturer can trace back through the RFID system to identify the root cause whether it was a faulty cell, incorrect temperature setting, or supplier issue.
Thus, using RFID, quality control becomes proactive rather than reactive. Such a granular level of data collection not only speeds up recall processes when necessary but also supports continuous improvement strategies and ISO compliance.
Gigafactories producing EV batteries operate at scale and managing hundreds of WIP batches simultaneously is complex. RFID tags attached to battery cell trays or containers allow real-time location tracking as items move through formation, aging, and testing phases.
Popular EV manufacturing firm Tesla has six operational Gigafactories located in Fremont, California; Sparks, Nevada; Austin, Texas; Buffalo, New York; Berlin, Germany; and Shanghai, China. These large-scale EV manufacturing firms leverage RFID technology to allow floor supervisors to monitor WIP bottlenecks, maintain optimal process times, and ensure first-in-first-out (FIFO) sequencing. RFID solutions also reduce the risk of cells sitting too long in unfavorable conditions, which could degrade battery performance or safety.
6. RFID for Returnable Transport Items (RTIs)
Battery production and vehicle assembly involve frequent movement of returnable containers whether for cells, modules, cooling plates, or casings. RFID tagging of these RTIs ensures they are accounted for at every stage, reducing losses and theft.
Additionally, by integrating RFID technology with route management systems, manufacturers can optimize container circulation between supplier plants and OEM assembly lines, improving cost control and sustainability.

7. Enabling Predictive Maintenance and Safety
Chipless RFID sensors can also be embedded into EV battery packs or cooling systems to monitor parameters like temperature, voltage, and pressure in real time. Deploying these sensors not only aids during manufacturing but also post-sale, where service centers can read RFID data to understand battery usage history and wear.
Predictive maintenance becomes possible by correlating this data with failure trends extending battery life and improving customer satisfaction. In critical environments like public transport or fleet operations, this can be a game-changer for safety and uptime.
To summarize, as India accelerates toward electric mobility, the need for precision, transparency, and efficiency in Li-ion battery and EV manufacturing is more urgent than ever. While we need to step up our EV and Li-ion battery production, we must also employ technologies like RFID and IoT sensors and network gateways, BLE beacons to automate accurate data collection at various stages of EV production. RFID technology, with its ability to provide real-time tracking, ensure quality control, and automate workflows, is no longer a luxury but a necessity. With global EV automakers like BMW, Tesla, and BYD setting benchmarks in RFID-driven EV manufacturing, now is the time for Indian automakers and battery suppliers to embrace RFID and IoT technologies for a cleaner, smarter, and more sustainable future which is the need of the hour.
