Electric vehicle Technology

After years of developing motors, I’ve learned one thing. Prototype proves it. Production validates it. Cost, tolerances, testing, reliability, And serviceability change everything. Prototype and production are two worlds. I’ve captured some key differences in this carousel. ⚙️ Can your prototype survive 10,000 units? #ElectricMotors #EV #MotorDesign #Manufacturing

I see BaaS creating new possibilities. It can reshape EV economics. EVs can be easier to buy. I have written about BaaS before. MG Windsor, Tata Tiago, Mahindra BE 6, XEV 9S, Hyundai Creta Electric, Kia Syros already implemented this. The idea is bigger than pricing. It separates the vehicle from battery. That changes the ownership equation. The upfront cost comes down sharply. Battery usage becomes a separate expense. For instance as per the news article, Mahindra's model sh

Tesla is entering Chennai. But India can offer much more. Could local manufacturing be next? Lets dive in 👇 Tesla now has six Indian outlets. Sales crossed 600 cars this year. But ₹50.89 lakh changes the story. This still remains a premium play. Chennai can change that equation. Its automotive ecosystem runs deep. Localisation can significantly reduce vehicle costs. Battery packs, electronics and components can localise. Tesla’s India sourcing is accelerating. Component purc

I didn’t expect this surprise! Met Ather Co-founder Swapnil Jain I’ve always been fascinated by Ather. Especially how they think and build. Meeting Swapnil and having this conversation felt special. His decade-long Ather journey was fascinating. Building EVs then was far tougher. Imagine building EVs during those early days. The ecosystem was nowhere near today’s level. His insights were practical and inspiring. Especially his thoughts on ecosystem building. A great conversat

Had a wonderful conversation yesterday during the podcast with Soundarya Lakshmi Narayanan, Circuit Digest team. Topic: "India Doesn’t Need More EV Startups, It Needs 500 Component Suppliers" We spoke about India’s EV ecosystem. And why suppliers matter so much. We also discussed Drivecore’s journey. Especially our rare-earth-free motor technology. Episode coming soon! #EV #ElectricVehicles #EVIndustry #CircuitDigest CircuitDigest , Aswinth Raj

The question is: How often does the vehicle Actually operate there? What if most of your drive cycle Happens far away from that operating point? For EVs, The better question may not be: “What's the peak efficiency?” It may be: “How efficiently does the motor operate in the real world?” I believe the efficiency map tells a much Bigger story than the peak efficiency number. Is peak efficiency becoming an overrated EV metric? Should we focus more on the efficiency map than the

Claims Cybercab has zero rare earths, without losing range. EV motors are entering another race. This time, it is not about magnets. Tesla’s Cybercab has changed the conversation. Elon Musk says its drive motor uses no rare earths. He also says range is not reduced. That is technically very interesting. Why is this so difficult? Strong magnetic output needs strong materials.NdFeB magnets provide extremely high magnetic flux. Ferrite magnets are much weaker. So this becomes a

India doesn't need more EV startups. It needs 500 more component suppliers. Components include motors, Controllers, batteries, and BMS. Also chargers, ECUs, and Supporting accessories. The evolution of India's trade shows is already making this visible. Strong supply chains build strong industries. Suppliers create speed, quality, and resilience. A strong ecosystem needs both people and products. Trade shows and exhibitions are evolving rapidly. My recent visit to the MOG

27% of India is aged 15–29. USA has 20% in this group. UK has 18% in comparison. That is our biggest strategic asset. What if we protect every percentage? But the drug data worries me more. 2.26 crore people use opioids. 40 lakh children use opioids. 30 lakh use inhalants. These are not just numbers. They represent our future workforce. Drug abuse creates multiple risks. Every addiction is more than lost health. It can mean lost human potential. Lost skills. Lost productivity

My last three months as a first generation enterpreneur, showed me why. Many investors claim seed-stage or early investor on their Linkedin bio. But their expectations suggest otherwise. “Show stronger technology IP.” “Prove customer traction first.” “Come after commercial orders.” "Market in Crowdy" Is that really seed-stage investing? Deep-tech follows a different curve. Motors need dyno testing and durability validation. Controllers need hardware-software integration

Attended Smart India Hackathon ( SIH ) At Sathyabama yesterday as an evaluator. The experience was genuinely wonderful. Young engineers were solving real problems. They were thinking about ground-level execution. Students applied AI to the Problems we rarely associate with AI. I saw AI detecting cyber threats. Others tackled civic and water issues. Some focused on mental-health guidance. Another improved Northeast logistics accessibility. Creating digital platforms for report

I have been observing this infographic. USA has NVIDIA. Japan has Toyota. China has Alibaba. India has……? I know, everyone uses This infographic as sarcasm. But India has immense talent. We have scale and ambition. We have the potential to lead. Let’s settle this. Who represents India? Share your choice in the comments. Tell the world why you chose it. 🇮🇳 #MakeInIndia #IndianInnovation #IndiaRising #AtmanirbharBharat #GlobalIndia

Koenigsegg’s Dark Matter caught my attention. It delivers 600 kW peak power. And 1,250 Nm peak torque. All from just 39 kg. That means roughly 15.4 kW/kg. 🚀 I also came across the YASA motor recently. Its motor reportedly delivers 750 kW. The motor weighs only 12.7 kg. That means 59 kW/kg peak power density. But the numbers aren't everything. The architecture is equally interesting. YASA uses an axial-flux design. Dark Matter combines axial and radial flux. Dark Matter's mot

If an EV stops working, Many blame the battery. If efficiency drops, Many blame the motor. But one component quietly Decides how effectively The motor performs: The inverter. The inverter decides Motor current, energy conversion, Torque response, regeneration, and even How much heat the motor generates. The same motor can perform very differently With different inverter control strategies. Modern EV performance isn't just hardware. Control algorithms influence: NVH Efficiency

Electric trucks make even more sense to me now. I recently saw the Montra EVIATOR at an event. It made me think about one thing. Commercial EVs aren't Just about mobility. They're about impact. How important are commercial vehicles in controlling urban pollution levels? Recent CSE analysis for Delhi-NCR says: Heavy trucks and buses are only 3% of the vehicle fleet. Yet they generate 36% of vehicular PM emissions. Transport contributes 63% of NOx emissions in the region. A pri

When choosing between petrol and EV, I considered my long-drive interests. Highway charging infrastructure still has gaps. That matters during long-distance travel. For city driving, EVs work well. For long drives, confidence matters more The problem is not always range. A petrol pump rarely needs planning. EV charging often needs planning. Availability, uptime, and payment matter. One failed trip breaks Consumer confidence. ⚡ That difference changes Ownership behaviour. Char

Yes, Lower weight improves efficiency, Acceleration, and vehicle dynamics. 🏍️ But lightweight designs often Introduce new challenges: Structural Integrity concerns Manufacturing complexity Thermal limitations Cost pressures Let's dive deeper now. 🎯 Copper vs weight Reducing copper lowers Mass But can increase: Current density Temperature rise Copper losses Cooling requirements ( adds cost ) 📖 Take-away: Less copper can Mean more heat. 🎯Iron vs efficiency Reducing stator/r

I believe localisation matters most At the component level. Motor localisation needs deeper capability. It means localising laminations, windings and rotors. Magnet dependency remains a key challenge. Controller localisation needs similar depth. Power electronics remain critical for localisation. MOSFETs, MCUs and sensors need attention. India’s supply chain capabilities are strengthening. Not just assembly, but critical child parts. Motors and controllers need local depth to

I just read an interesting Autopunditz report. It hints at a possible Nano EV comeback. As a motor engineer, I find this interesting. With my experience in EVs for more than two decades, The Nano philosophy still makes sense today. Compact size. Efficient packaging. Low energy consumption. Simple urban mobility. Smaller batteries reduce weight and cost. Motor efficiency becomes even more critical. Thermal management must remain compact too. Lower weight reduces motor
