Introduction

How long does it take to charge an electric car? Add to that, what decides the EV charging time? Charging an EV isn't as quick as filling a fuel tank. It can take anywhere from 30 minutes to more than 12 hours. The time depends on the size of the battery, the type of charger, and how much charge is already left in the battery. This is exactly where many EV owners feel a little stuck. The numbers vary and the answers are not always simple. Whether you drive a compact electric scooter, a sleek four-wheeler, or you're thinking about getting your first EV, understanding how charging works is a big part of the journey.  

With this blog, let’s dive into how to calculate VE charging time, what affects charging speed, and what it means for you. 

How to calculate EV charging time 

Understanding how long it takes to charge your electric vehicle helps you plan better, whether you are heading out for a long drive or simply charging overnight. The good news is, calculating EV charging time is not complicated. With just a few numbers, you can estimate how long your EV will take to charge.

To estimate EV car charging time, you can use this simple formula:

Charging time (in hours) = Charge needed (kWh) ÷ Charger power output (kW)

This gives you an approximate number of hours required to reach your desired battery level.

For instance, let’s consider an electric car with an 80 kWh battery. The current battery level is 20 percent, and you want to charge it up to 80 percent.

  1. Calculate charge needed: 
    80% – 20% = 60% 
    80 kWh × 0.6 = 48 kWh

  2. Charging with a Level 2 charger rated at 7.68 kW: 
    48 ÷ 7.68 = approximately 6.25 hours

This is your estimated charging time for EV using this charger setup.

Factoring in charging efficiency 

Charging is not always 100 percent efficient. Some power is lost in the form of heat or during energy conversion. A good estimate is around 90 percent efficiency.

Adjusted formula: 
Charging Time = Charge Needed ÷ (Charger Power × 0.9) 
Using the same example: 
48 ÷ (7.68 × 0.9) = approximately 6.9 hours

This gives you a more realistic idea of your EV battery charging time.

Using an EV charging time calculator

If you do not want to calculate manually, you can use an EV charging time calculator on e-Amrit by NITI Aayog. To use it, simply enter details like battery capacity (in kWh), current battery level, target battery level, charging power (in kW), and efficiency, if available. The calculator will then give you an estimated time to charge EV under your selected conditions. These tools are useful if you are planning road trips or evaluating different chargers for home or office use.

How long does it take to charge an electric car at a charging station?  

Understanding how long it takes to charge your electric vehicle is one of the most common questions among EV users. Charging times vary depending on where you plug in, the charger’s power output, and your vehicle’s battery size. At home, using a standard 15-amp socket, a full charge can take anywhere from 8 to 15 hours, making overnight charging a convenient option for daily use. Public charging stations often provide faster options. Level 2 chargers, typically found in shopping centers or workplaces, can recharge your car in 4 to 8 hours, while DC fast chargers at highway stations can deliver an 80% charge in as little as 30 to 60 minutes.

Many EV drivers also use top-up charging during the day to maintain battery levels between longer trips. This flexible approach allows you to extend your range without waiting for a full charge. Knowing the right charging method for your needs and understanding different charging speeds can help you plan trips efficiently and make the most of your EV’s capabilities.

What are the factors affecting EV charging time in India? 

If you’re wondering why the EV charging time for your vehicle sometimes varies or why some EVs seem to charge quicker than others, it’s because several things come into play. Did you know not performing proper maintenance of your EV battery can reduce its lifespan?

Knowing these factors can help you plan your charging stops better and avoid surprises on the road.

1. Battery size matters

Think of your EV’s battery like a bucket, the bigger the bucket, the longer it takes to fill. Larger batteries (measured in kilowatt-hours or kWh) store more power but also need more time to charge fully. So, if you have a vehicle with a big battery, expect a longer EV car charging time compared to smaller batteries.

2. State of charge

If you plug in when your battery is nearly empty, it will take longer to charge than topping up when it’s half full. Also, batteries slow down charging after about 80 percent to protect themselves, so charging from 80 percent to 100 percent can take quite a bit longer than the earlier stages.

3. Vehicle’s maximum charging capacity

Your EV can only charge as fast as its built-in system allows. For example, if your car can handle charging at 7 kW max, then using a charger with 22 kW won’t speed things up. The car’s max charging rate limits how fast power goes in, so knowing this helps when using a charging time calculator EV or estimating EV charging time.

4. Charging station’s power output

Not all chargers are the same. Slow chargers like home chargers deliver less power, while fast public chargers can deliver a lot more. But your charging speed depends on the lower number between your vehicle’s max rate and the charger’s power. So, even if the station offers 50 kW but your car accepts only 7 kW, your EV battery charging time will be limited by your car.

5. Weather and temperature

In India, the weather varies a lot, from cold winters in the north to hot summers in most parts. Batteries work best between 20°C and 25°C. If it’s too cold or too hot, the battery management system slows charging to protect the battery. So, charging times can be longer in extreme heat or cold.

6. Multiple vehicles charging on one circuit (Load sharing)

In places with many chargers connected to the same power source, like apartment complexes or offices, the available power gets shared between all charging vehicles. This can slow down the charging speed for everyone if many cars charge at once.

7. Battery protection settings and age

Most EVs have smart systems that limit charging beyond 80 percent or keep the battery above 20 percent to keep it healthy for a long time. Following these settings may save battery life but might slightly increase charging time for EV. Also, older batteries tend to charge slower because they can’t accept power as efficiently as new ones.

8. Using heating or cooling systems while charging

Running air conditioning or heating while charging uses some power, which means less energy goes into the battery. So, if you’re using your car’s climate control during charging, your charging time of EV might increase a bit.

9. Battery composition and technology

Not all EV batteries are the same. Some use lithium-ion, others lithium iron phosphate (LFP). These differences affect how fast batteries can safely charge. For example, LFP batteries often handle fast charging better without overheating, which can reduce overall EV charging time.

10. Electrical grid stability and power supply

In many parts of India, electricity supply can be unstable or limited during peak hours. If the grid can’t provide steady power to a charging station, the station may reduce charging speed to avoid overloads. So sometimes your EV car charging time depends on how stable and strong the local power supply is.

11. Cable and connector quality

The quality and condition of charging cables and connectors also matter. Damaged or low-quality cables can restrict charging speed and even cause safety issues. Always use certified cables and keep connectors clean for best charging performance.

12. Software and firmware updates

Many EVs get updates that improve charging efficiency or battery management. If your car’s software is outdated, it might not charge as quickly as it could. Regular updates help ensure optimal EV charging time and battery health.

When you use an EV charging time calculator, knowing your battery size, charger power, and the current state of charge makes your estimate more accurate. Also, if you’re planning a trip or charging stop in India, considering weather and load sharing can save you time and frustration.

EV Charger Types in India: Level 1, Level 2, and DC Fast Charging Explained

Not all EV chargers are the same. Some are ideal for overnight charging at home, while others can power up your car during a quick chai break. In India, EV chargers are broadly classified into three levels based on how fast they charge your vehicle:

Level 1 charger (Slow charging)

This is the most basic form of EV charging. It uses the same 15A, 230V plug you use for a geyser or washing machine. The power output is usually between 2 to 3.5 kW.

- Suitable for overnight charging at home

 - Takes 8 to 12 hours to fully charge an EV

 - Ideal for two-wheelers, three-wheelers, or plug-in hybrid electric vehicles (PHEVs)

 - Convenient but slow, best for daily top-ups or low-usage vehicles

 - Common in homes across Indian cities like Pune, Jaipur, and Kochi, where overnight charging is the norm.

Level 2 charger (Fast charging)

Level 2 chargers are more powerful and much faster than Level 1. These operate between 7 and 22 kW using 240V AC.

 - Can fully charge most EVs in 3 to 6 hours

 - PHEVs can be charged in just 1 to 2 hours

 - Common at public parking areas, malls, office buildings, and even homes with dedicated wall-mounted units

 - Ideal for users with higher daily driving range

 - Widely installed in metro cities like Bengaluru, Delhi NCR, and Mumbai. Popular locations include DLF Cyber Hub in Gurugram, Phoenix Marketcity in Mumbai, and office complexes like Manyata Tech Park in Bengaluru.

Level 3 charger (Rapid charging or DC fast charging)

These are high-speed chargers using direct current (DC), usually delivering between 50 kW and 350 kW. They bypass the vehicle’s onboard AC-to-DC converter and deliver power directly to the battery.

 - Charges up to 80 percent in 20 to 60 minutes, depending on battery size and charger output

 - Mostly found on highways, petrol pumps, or commercial EV charging station franchises

 - Not typically installed at homes due to their high voltage requirements and cost

 - Essential for long-distance drivers or fleet vehicles that can’t afford downtime

 - Key locations include highway toll plazas like the Mumbai-Pune Expressway, Reliance petrol pumps with EV charging in Gujarat and Maharashtra, and commercial charging hubs in cities such as Hyderabad and Chennai.

Each type of charger has a role to play depending on your driving habits, your vehicle, and where you plan to charge it. If you mostly drive within city limits, a Level 1 or Level 2 charger might work perfectly. But if you're frequently taking longer trips, or if you operate a fleet, DC fast charging can save you significant time.

Understanding charger types helps you better plan your routes, estimate EV charging time more accurately, and pick the right setup for your home or business.
