By Mohan Sundar / EV & Engineering Why Electric Vehicles Don’t Need Gearboxes Electric vehicles (EVs) are becoming popular because they are efficient, smooth, and simpler than traditional gasoline or diesel vehicles. One major difference between EVs and conventional cars is that most EVs do not use multi-speed gearboxes. While petrol and diesel vehicles require … Read more
By Mohan Sundar / EV & Engineering Understanding EV Battery Percentage Unlike a smartphone battery, an EV battery never truly reaches absolute zero. When the dashboard shows 0% State of Charge (SOC), the Battery Management System (BMS) still keeps a small hidden reserve of energy to protect the battery cells from permanent damage. This protective … 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 In the rapidly evolving landscape of 2026, electric vehicles (EVs) have transitioned from a niche luxury to a mainstream reality across the USA and Europe. While the initial conversation around EVs focused primarily on range, the narrative has shifted toward efficiency. For the mechanical engineer, the technical … Read more
By Mohan Sundar / EV & Engineering The Rise of Electric Vehicles Electric Vehicles, commonly known as EVs, have moved far beyond being a futuristic idea. By 2026, they have firmly established themselves as a practical and rapidly growing mode of transportation across the globe. Governments are offering strong incentives, charging infrastructure is expanding at … Read more
By Mohan Sundar / EV & Engineering 1. What Is Fast Charging? Fast charging, also known as DC Fast Charging, delivers high-power direct current directly to the battery, allowing an EV to recharge much faster than conventional AC charging. Depending on the charger and vehicle, a battery can be charged from 20% to 80% in … Read more
By Mohan Sundar / EV & Engineering Many electric vehicle owners notice that charging is incredibly fast up to around 70–80%, but then the charging speed drops significantly. A charger capable of adding hundreds of kilometers of range in minutes suddenly seems much slower during the last 20% of charging. This behavior is completely normal … Read more
By Mohan Sundar / EV & Engineering Electric vehicle batteries are designed to last many years, but driving conditions can significantly affect their lifespan. Surprisingly, many EV owners assume highway driving is harder on the battery because of higher speeds. In reality, frequent city traffic can accelerate battery degradation in several ways due to constant … Read more
Mohan Sundar / EV & Engineering What Is an Electric Scooter? An electric scooter is a two-wheeled vehicle powered by an electric motor instead of an internal combustion engine. Energy is stored in a rechargeable battery pack and supplied to the motor through an electronic controller. When the rider twists the throttle, the controller regulates … Read more
