10 Ways to Maximize the Lifespan of Your Electric Vehicle’s Battery


It’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 reduced battery life. Most people develop a habit of charging their EV battery up to 100% on a regular basis. This causes damage to the battery in the long run. Ideally, an electric vehicle’s battery should be charged up to 80%. The Tata Nexon EV is equipped with a 30.2 kWh li-ion battery, which delivers unbeatable performance.

2.Avoid draining out your battery– While you should avoid charging your battery to a 100%, you should also avoid draining it out completely before charging it. Recharge your battery when you find that it is around 30%. This will prevent your battery from wearing out and more importantly, you will never run out of charge while on the road.

3.Time your charge – People often have a habit of charging their electric vehicle every night so that their car is ready for the next day. Charging overnight may help save time, but it is not good for the battery when done on a frequent basis. It is important for you to clock the duration of charging. The Tata Nexon EV, for example, takes approximately 8.5 hours to get fully charged from a regular 15 Ampere AC plug point. Overcharging can cause damage to the batteries in the long run. Timing the duration of charge will not only help increase the lifespan of the battery but also help you cut down on electricity consumption and, as a result, save money too.

4.Park in the shade – During the day, avoid parking your car in places that are exposed to direct sunlight. This will prevent the batteries from overheating. Find a spot under a tree or any other shady place, and park your vehicle there. Additionally, it will also help keep the vehicle cool.

5.Avoid frequent Quick Charging – Many EVs come with a quick charging option. With Tata Nexon EV’s fast charging option, you can charge from 0% to 80% in 60 minutes. However, the regular charging option is recommended to help sustain battery life. The Tata Nexon EV can be charged from 0 to 90% in 8.5 hours from any regular 15 Ampere AC plug point.

6.Drive slowly – Driving too fast tends to drain the battery faster. Try to take a route with slower speed limits, so that the vehicle does not put too much pressure on the battery. The lesser the load on the battery, the longer its battery life. Driving slow not only helps the batteries but also helps you observe traffic rules.

7.Low Battery – Do not leave your car battery uncharged for a long period of time. Even if the car is not moving, the battery can get discharged. Try to keep your battery charged to an optimal 80% to 90% SOC (state of charge level) at all times. This will help it last longer.

8.Plan your commute in advance - Planning your trip in advance is always a good practice. It helps you take a route with the shortest distance, which, in turn consumes less battery. Another important reason for advance planning is that you can locate charging stations along the way. The Tata Motors ZConnect app helps to locate your nearest charging station and provides a navigation option as well.

9.Minimize the use of the air conditioner – Keeping the air conditioner (AC) on for too long, and on high speed can cause the battery to drain faster. Whenever possible, try to avoid using the air conditioner. Instead, keep the window open and enjoy some breeze from time to time.  When using the air conditioner, keep the temperature within optimal range, 24 to 26 degrees Celsius, to reduce the energy consumption. The Tata Nexon EV comes with FATC (Fully Automatic Temperature Control) as a standard across all variants, which helps to keep the temperature within the optimal range.

10.Be mindful of the weight – It is always recommended to travel light. A heavy load on the car increases the vehicle’s energy consumption. Little things like these can impact the batteries a lot more than it might seem.

The above-mentioned tips will help you take care of your electric vehicle’s battery and, thereby, ensure many happy journeys ahead.

PMSM versus BLDC - Which motor powers your Electric Car better?

Image
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 windings,

Common Electric Car Myths Busted

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

The Role and Importance of Inverters and Converters in an Electric Vehicle

Image
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 generally a set
