Electric Vehicle

When compared to conventional petrol or diesel-run cars, electric cars have significant differences and several benefits. With an increasing number of people opting for electric cars, it is important to understand the working of the internal parts of an electric vehicle. One  of the most vital parts of an automobile is its control system. In electric vehicles, these are more complex and have additional components like high voltage batteries, motors, inverters, converters, pumps and regenerative brakes. The  inverter and converter are two key components that work together to manage the power and recharging the circuits.  An inverter is an electrical device that converts electricity derived from a Direct Current (DC) source to Alternating Current (AC), which can be used to drive a device or appliance. The inverter receives DC power from the battery and directs it towards the primary winding in a transformer within the inverter itself. Through an electronic switch which is g...

Together with electric batteries and controller systems, the electric motor forms the heart of an electric vehicle (EV). An electric motor converts electrical energy into mechanical energy to propel the electric car. While  designing an electric vehicle, automobile manufacturers in India and across the world have to keep an eye on the size, weight and aerodynamics of the electric car to select the right electric motor. There are many variables such as speed, torque and power requirements to consider before fitting the right motor because it affects the performance of the car. The early electric vehicle models in India were fitted with Brushless DC motors (BLDC). The  BLDC motor is known as an advanced version of a Brushed DC motor . It has two major parts - a rotor and a stator. The rotor is the movable part that has permanent magnets known as the rotor magnets. The stator is the stationary part made up of coil windings. When electric current passes through the stator’s coil w...

I t’s no secret that the battery of an electric vehicle (EV) is very different from that of a petrol or diesel car.  In the case of an electric vehicle, it’s the battery that runs the car and is the main source of power. This raises several questions about the battery’s lifespan. However, the answer remains the same: the lifespan of a battery depends on the effort taken to maintain it. With the right amount of maintenance, you can make the most of your electric vehicle’s battery. The Tata Nexon EV is powered by an IP 67 rated 30.2 kWh battery pack with an ARAI certified range of 312 kms. The battery pack and the motor are covered under a warranty that spans 8 years or   1,60,000 kms, whichever comes first. To take extra care of your vehicle’s battery, we have listed a few tips to make sure you are never stranded at the side of the road with a depleted battery.   1.   Avoid full charge –Charging the battery to its maximum limit is one of the most common causes of re...

As air pollution worsens, the need for electric vehicles heightens. For many people, electric cars are a thing of the future. But what most people do not understand is that the “Future is Now”; that electric cars are being launched at an accelerating rate and one of the key reasons is the rising concerns around CO2 emissions. While this ushers in a new form of mobility, several misconceptions come along with it. We have laid down a few common myths with the straight truth about electric cars. Myth: There’s no such thing as a fast charging electric car Truth: With newer batteries and technological breakthroughs, the time taken to charge an electric car has decreased sharply. Charging an electric vehicle all comes down to how powerful your charging point is and of course, the capacity of your battery. The Tata Nexon EV, for example, charges from SOC (state of charge) 0% within eight and a half hours from any 15 Ampere plug point – that’s pretty much around the same time you spend sleep...
