How much does it Cost to Charge an Ebike?

If you are considering buying an electric bike or already own one, you might be wondering how much it costs to charge it. Electric bikes are a great way to get around, especially if you want to save money on gas, reduce your carbon footprint, and enjoy a fun and healthy ride. But how much must you pay for the electricity that powers your ebike?

 

In this blog post, we will answer this question and show you how to calculate the cost of charging your electric bike. We will also compare the cost of charging an e-bike with the cost of driving a car and give you some tips on reducing your electricity bill. Finally, we will look at a case study of the cost of charging an e-bike in NY/LA/Seattle, where we will compare the cost of charging an ebike with other modes of transportation.

 

How to Calculate the Cost of Charging an E-Bike


The cost of charging an electric bike depends on several factors, such as:

  • The battery capacity of your e-bike
  • The battery level of your ebike before charging
  • The efficiency of your charger
  • The electricity rate in your area

 

To calculate the cost to charge an electric bike, you need to know two things: your battery’s watt-hours (Wh) and the electricity rate in your area.

 

Your battery’s watt-hours (Wh) measure how much energy your battery can store and deliver. You can find this information on your battery label or e-bike manual. For example, if your battery has a capacity of 500 Wh, it can provide 500 watts of power for one hour, 250 watts for two hours, 100 watts for five hours, and so on.

 

The electricity rate in your area is the price you pay for each kilowatt-hour (kWh) of electricity you use. You can find this information on your electricity bill or by contacting your utility company. For example, if the electricity rate in your area is $0.15 per kWh, you pay $0.15 for every 1000 Wh of electricity you use.

 

Once you know these two numbers, you can use this formula to calculate the cost of charging your electric bike:

Cost = (Wh / 1000) x Electricity Rate

For example, if your battery has a capacity of 500 Wh and the electricity rate in your area is $0.15 per kWh, the cost of charging your e-bike from empty to full is:

Cost = (500 / 1000) x 0.15

Cost = 0.5 x 0.15

Cost = $0.075

That means it costs only $0.075 to charge your e-bike from empty to full!

 

However, this simplified calculation assumes that your battery is empty before charging and that your charger is 100% efficient. In reality, these assumptions are not always accurate.

 

First, you might only sometimes drain your battery completely before charging it. For example, if you only use half of your battery capacity before plugging it in, you will only need half as much energy to charge it back to full. In that case, the cost of charging your e-bike will also be half as much.

 

Second, your charger might be less than 100% efficient. Some energy might be lost as heat during the charging process. The efficiency of your charger depends on its quality and design. A typical charger might have an efficiency of around 80%, which means it converts 80% of the input energy into output energy and loses 20% as heat. In that case, you will need more input energy to charge your battery than what your battery actually stores.

To account for these factors, you can use this formula instead:

Cost = (Wh x Battery Level x Charger Efficiency / 1000) x Electricity Rate

For example, suppose your battery has a capacity of 500 Wh and the electricity rate in your area is $0.15 per kWh. Still, you only use half of your battery capacity before charging it and your charger has an efficiency of 80%. In that case, the cost of charging your ebike is:

Cost = (500 x 50 x 80 / 1000) x 0.15

Cost = (20000 / 1000) x 0.15

Cost = 20 x 0.15

Cost = $3

That means it costs $3 to charge your e-bike from half-empty to full with an 80% efficient charger.

 

As you can see, the cost of charging your ebike can vary depending on how much you use it.

 

Comparison of the Cost of Charging an Electric Bike vs. a Car


If you are considering switching from a car to an electric bike, one of the factors that you might consider is the cost of charging. How much does it cost to charge an ebike compared to a car? And how much can you save by using an electric bike instead of a car?

 

The answer depends on several factors, such as your electric bike’s battery capacity and efficiency, the electricity rate in your area, and the distance and frequency of your trips. However, charging an electric bike is much cheaper than fueling a car.

 

To illustrate this point, let’s take a look at some examples. According to the U.S. Department of Energy, the average fuel economy of a new car in 2020 was 25.7 miles per gallon (mpg), and the average gas price in April 2021 was $2.86 per gallon. This means that driving a car costs about $0.11 per mile.

 

On the other hand, the average battery capacity of an electric bike is about 500 watt-hours (Wh), and the average electricity rate in the U.S. in April 2021 was $0.13 per kilowatt-hour (kWh). This means charging an electric bike costs about $0.07 per full charge. Assuming that an electric bike can travel about 30 miles on a full charge, this means that riding an electric bike costs about $0.002 per mile.

 

These numbers show that charging an electric bike is about 55 times cheaper than fueling a car per mile. Of course, this is a rough estimate, and your savings may vary depending on your situation. But using an electric bike can significantly reduce your transportation costs compared to using a car.

 

Case Study: Cost of Charging an Electric Bike in NYC/LA/Seattle


Let’s take a look at a case study to give you a more concrete idea of how much it costs to charge an electric bike in different locations. We will compare the cost of charging an electric bike in New York City, Los Angeles, and Seattle.

 

Overview of the location’s electricity rates

The electricity rates in these three cities vary widely depending on the time of day, season, and provider. However, for simplicity, we will use the average residential electricity rates from April 2021, as the U.S. Energy Information Administration (EIA) reported.

According to the EIA, the average residential electricity rates in April 2021 were:

  • New York City: $0.22 per kWh
  • Los Angeles: $0.19 per kWh
  • Seattle: $0.10 per kWh

 

Comparison of the cost of charging an electric bike with other modes of transportation

Using these electricity rates and assuming a battery capacity of 500 Wh and a range of 30 miles for an electric bike, we can calculate the cost of charging an electric bike per mile in each city:

New York City: $0.004 per mile

Los Angeles: $0.003 per mile

Seattle: $0.002 per mile

Now let’s compare these costs with other modes of transportation available in these cities. According to Numbeo.com, a website that provides the cost of living data for various cities around the world, the average prices of other modes of transportation in these cities are:

– New York City:

  – Subway: $2.75 per ride

  – Taxi: $2.50 initial charge + $2.50 per mile

  – Car: $0.11 per mile (based on the national average)

– Los Angeles:

  – Metro: $1.75 per ride

  – Taxi: $2.85 initial charge + $2.70 per mile

  – Car: $0.11 per mile (based on the national average)

– Seattle:

  – Light rail: $2.25-$3.25 per ride, depending on the distance

  – Taxi: $2.60 initial charge + $2.70 per mile

  – Car: $0.11 per mile (based on the national average)

 

Based on these numbers, charging an electric bike is much cheaper than any other mode of transportation in these cities per mile. For example, in New York City, charging an electric bike is about 688 times more affordable than taking a taxi and about 28 times cheaper than taking the subway.

 

Of course, these comparisons do not consider other factors such as convenience, comfort, safety, parking fees, maintenance costs, etc., which may affect your transportation mode choice.
