Mohan Sundar / EV & Engineering The rapid expansion of electric mobility has triggered an unprecedented surge in lithium-ion battery manufacturing. However, millions of electric vehicles (EVs) hitting the roads today create a massive looming challenge for tomorrow: What happens when these batteries reach the end of their lifecycle? EV battery recycling is no longer … Read more
Mohan Sundar / EV & Engineering The global shift toward electric vehicles (EVs) has ignited an intense engineering and infrastructure debate: How should we replenish an EV’s energy? For years, standard plug-in charging has been the default method. However, battery swapping technology—where a depleted battery is mechanically replaced with a fully charged one in minutes—is … Read more
Mohan Sundar/ EV & Engineering What Is Regenerative Braking? When a vehicle slows down, it possesses kinetic energy. Traditional braking systems dissipate this energy as heat through friction. Regenerative braking systems recover a portion of this energy and store it for future use, improving overall efficiency and reducing energy consumption. How Regenerative Braking Works in … Read more
By Mohan Sundar / EV & Engineering What is a BLDC Motor? A Brushless DC Motor (BLDC) is an electric motor that uses permanent magnets on the rotor and electromagnets on the stator. Unlike traditional brushed motors, a BLDC motor does not use mechanical brushes for commutation. Instead, an electronic controller switches the current … Read more
By Mohan Sundar / EV & Engineering Introduction to Braking System Design Have you ever observed that most cars and motorcycles are equipped with disc brakes on the front wheels while the rear wheels often use drum brakes? This design is extremely common, especially in budget and mid-range vehicles, and it is not simply a … Read more
By Mohan Sundar / EV & Engineering Introduction to Transformer Ratings Transformers are among the most essential machines in electrical power systems, silently enabling the transmission and distribution of electricity across cities, industries, and homes. Despite their widespread use, one question often confuses engineering students and beginners: why are transformers rated in kilovolt-amperes instead of … Read more
Introduction A phone charging on a nightstand. An e-bike battery left plugged in overnight. A power bank tossed into a backpack beside a laptop. They all look harmless, until something goes wrong. Lithium-ion battery fires are becoming a growing fire safety concern across the United States and Europe. Fire crews in New York City respond … Read more
