IoT-Monitored and Controlled Isolated Bipolar DC-DC Converter for Electric Vehicle Battery Charging System Srinivasan P., N. Sankar Ram, M. Sadhasivam, D. Kabilan International Energy Journal, 2026 With the increasing popularity of electric vehicles (EVs), there's a rising demand for advanced power conversion systems that boost efficiency, reliability, and safety in charging batteries. This research presents the development of a specialized isolated bipolar DC-DC converter designed specifically to enhance the integration of energy storage in electric vehicle battery charging systems. The bipolar power outputs, essential for ensuring balanced charging and increasing the lifespan of the batteries, will be stable as well as efficient due to switching functions controlled by the converter using the dsPIC30F2010 microcontroller. To enhance monitoring features in the main control unit, the system includes an ESP32 microcontroller, based on IoT. With this arrangement, you can keep an eye on key battery metrics like voltage and temperature in real time, all thanks to wireless technology. This IoT-connected system not only boosts clarity in how charging works but also helps manage issues by sending out warnings for problems like overheating or too much voltage. This monitoring system enhances battery safety and extends its lifespan during operation. Isolated design gives this converter the advantages of increased electrical safety and interference reduction, making it perfect for fragile automotive environments. In simulation, the converter stepped up a 50 V input to 320 V DC, delivering a battery current of 85 A at 80.6% SOC, verified under resistive loading with a 10 kHz switching frequency. A FOPID controller provided precise voltage regulation and stable operation across varying duty cycles. In hardware implementation, the prototype achieved output regulation between 12 V–34 V at switching frequencies up to 25 kHz, with efficiency exceeding 90% and stable thermal performance under load variations. Real-time monitoring of battery voltage, current, and SOC% was realized through the Blynk IoT application, providing predictive fault alerts against overvoltage, overheating, and abnormal charging patterns. Hardware-based implementation in real conditions clearly demonstrates its practical application and efficiency. This converter combines strong power electronics with smart control and monitoring, improving EV charging systems by tackling both technical and practical issues related to high-performance and safe battery management systems.
Underwater Wireless Sensor Networks with Energy Efficient Routing Protocol Using Load Balancing Technique Tapas Bapu, Pradeep S, Nagaraju V, Partheeban Nagappan, Sankarram N, et al. Ecs Transactions, 2022 Underwater Wireless Sensor Networks is effective and intelligent utilization of energy for routing protocol in longer network lifetime. Energy Consumption and load balancing are the vital roles for a network lifetime. The use of load balancing in WSN is granted as the best resource of sink mobility which protects energy sources to organize. The aim of this paper is to evaluate various deployed strategies involving sink mobility. Multiple mobile sinks are capable of performing computational operations like collecting information from electric joints instantly, storage and also communication capability. It evaluates the results and the effect of sink mobility by comparing with another routing protocol GEDAR.

Recommendation based on prediction of commuter flow and occupancy in bus transport M. Sreekrishna*, N. Sankarram, Dinesh Sha, Dakshin, Ashwini, et al. International Journal of Recent Technology and Engineering, 2019 The current public transportation in India is found to have higher traffic congestion levels within the bus and is an inefficient transport system for the public. The traffic and the over congested public transports we see on the roads is an effect of this problem. Increasing the public transportation is not the only solution, to make it better we also need to make it smarter. Though there are many other proposals for smart transportation we have come up with a unique way of approaching it. The aim is to provide smartness to the existing transportation system so that it becomes efficient and user-friendly for the public. The public need not depend on the paper tickets anymore and instead can have an smart RF ID with themselves which is not a big issue since its just credit card sized. One big advantage with this system is that public who are waiting to board can know the number of passengers in the vehicle and can decide whether to board or not beforehand. By this way the higher authorities can also see if there is a scarcity in any particular route and can immediately send more vehicles in the particular route. Using this technique, the congestion of the vehicles can be reduced and it will be easier for the public to make use of the public transportation system.
