Introduction
Electric vehicles (EVs) are rapidly accelerating the global transition toward sustainable transportation. But what happens when their high-voltage batteries retire from vehicle duty yet still retain significant storage capacity? Rather than letting them sit unused or go straight to recycling, EV batteries can begin a valuable Second Life. This blog explores how repurposing these batteries boosts sustainability, supports energy systems, and how IoT solutions like IoTNarad can unlock deeper operational intelligence across industries.
What Are Second-Life EV Batteries?
When an EV battery degrades to around 70–80% of its initial capacity — no longer ideal for powering vehicles — it can be repurposed for stationary energy applications without being “dead.”
- These batteries still hold valuable energy storage potential.
- Second-life use can support grid storage, renewable integration, microgrids, home energy systems, demand side management, and more.
- Repurposing reduces environmental impact by lowering landfill waste and diminishing the demand for new raw materials.
Benefits to Sustainability and Economics
Second-life EV batteries are more than a reuse story — they are central to circular economy strategies:
Environmental:
• Extending battery life delays recycling and reduces greenhouse emissions tied to material extraction.
Economic:
• Retrofitting old batteries for energy storage is often less expensive than manufacturing new stationary battery systems.
• Their deployment in residential or commercial systems can yield cost savings on energy bills.
IoT: The Missing Link to Operational Intelligence
While second-life batteries add value, managing them effectively requires real-time data visibility and control. That’s where IoTNarad, a universal IoT gateway, becomes essential:
