Introduction – The Types of Chargers Affect Charging Time
Charging infrastructure has improved considerably in the last 10 years. In the early times of EVs, in the early 2010’s, the most common way of charging was through a standard 120-volt outlet, which will take many hours to fully charge an EV. A faster way to charge an electric car is by using a Level 2 240-volt charger, which reduces charging time. With a Level 2 7.2 kW charger, it will take about 9 hours to fully charge an electric car, but see our table below because 7.2 kW charging time depends on the size of the battery in the electric vehicle. Most electric cars can accept this charge rate, although some may be limited to a lower rate.
In the “7.2 kW” number, the “kW” stands for kilowatts and is the unit for power, or the amount of energy moved into the battery over a certain time. If the kilowattage is high, then the energy moved is fast and the battery is charged quickly. But what is “high”, depends on your tolerance for the how long to wait, the capacity of your battery, and the efficiency of your car.
7.2 kW Charging Time Factors
7.2 kW charging time will depend on the size of the battery in your electric vehicle. For example, a smaller battery will charge faster than a larger battery. This is because a smaller battery will have less stored energy that needs to be replenished. In addition, the 7.2 kW charging time also depends on the type of charger you are using.
A Level 1 charger, the slowest charger, will take much longer to charge a 7.2 kWh battery than a Level 2 or Level 3 charger. Finally, the 7.2 kW charging time to a specific range or mileage will vary depending on the efficiency of your electric vehicle. Efficient vehicles will travel further on a smaller charge. Large EV trucks for example are less efficient, like the popular Ford Mach E. Therefore, it is important to consult your owner’s manual to determine your electric vehicle’s specific 7.2 kW charging time.
How Much Range Do You Get Per Hour Of Charging For 7.2 KW?
As we mentioned, the range charged by the 7.2 kW charger will vary depending on your car. At Level 1 charging, 120 volts and 15 amps will charge your car at about 2-5 miles per hour. This is the equivalent of plugging your car into a standard outlet in your home. A level 2 charge, 240 volts and 30-40 amps, will charge your car at about 10-20 miles per hour. This is the equivalent of using a public charger or installing a home charger.
A level 3 charge, which is 480 volts and 100-250 amps, will charge your car at about 50-100 miles per hour. This is the equivalent of using a high-speed charger at a public charging station. The time it takes to charge your car will depend on the size of your battery and the type of charger you use.
If you’re talking about how far you can drive on a full charge, the answer will vary depending on factors like your vehicle’s efficiency and the terrain you’re driving on. In general, you can expect to get about 100 miles of range from a full charge with a 7.2kW charger. So, there you have it! How much range you get per hour of charging for 7.2 kW depends on what you’re looking for.
Whether you need power for a long road trip or just want to be able to top off your battery quickly, there’s a solution out there for you. Now all that’s left to do is figure out which one is right for you!
7.2 kW Charging Time To Full And To 30 Miles of Range For Top 10 Selling EVs In US
Below we created a handy chart that has calculated the 7.2 kW charging time for the top 10 selling EVs in the US. The calculations take into account the size of the battery. We also calculated the time it takes to charge up to 30 miles of range. The amount of electricity needed for 30 miles of range is different for each car because of differences in efficiencies. The lowest efficiency car in the top 10 is the Ford Mustang Mach E which is a truck. The most efficient car is the Tesla Model 3. We didn’t provide numbers of every option of the model, because that would be difficult and confusing and not so useful because the differences in those numbers from the table below would get overwhelmed by real world uncertainties. Instead we used numbers for the most “standard” option.
| Manufacturer | Model | Battery Size | Range (miles) | Range (km) | Efficiency | 7.2 kW charge time to full | 7.2 kW charge time to 30 miles |
| Tesla | Model Y | 82 kWh | 339 miles | 542 km | 4.1 miles/kWh | 11 hours, 24 min | 60.5 min |

7.2 kW Charging Time To Full And To 30 Miles of Range For Top 10 Selling EVs In Europe
We also created the same chart of 7.2 kW charging time for the top 10 selling EVs in Europe because the popular cars are different. Instead of the Audi and Porsche in the US, smaller and more efficient cars made the car for the European Top 10, perhaps speaking to government support of efficient or social consciousness. These calculations also take into account the size of the battery and the time it takes to charge up to 30 miles of range. We still didn’t provide numbers of every option of the model to avoid complexity. Here we used numbers for the most “standard” option.
| Manufacturer | Model | Battery Size | Range (miles) | Range (km) | Efficiency | 7.2 kW charge time to full | 7.2 kW charge time to 30 miles |
| Tesla | Model 3 | 60 kWh | 309 miles | 495 km | 5.2 miles/kWh | 8.3 hours | 48.5 min |
| Renault | Zoe ZE50 R110 | 52 kWh | 246.875 | 395 km | 4.7 miles/kWh | 7.2 hours | 52.7 min |

What Factors Affect 7.2 kW Chargers Charging Speed?
The speed of a 7.2 kW charger is affected by many factors, from the type of electrical outlet to the distance from the power source. Let’s take a look at each of these factors in turn.
The first factor is the type of electrical outlet. A standard 110-volt outlet will charge a 7.2 kW charger much slower than a 220-volt outlet. If you’re looking to charge your 7.2 kW charger as quickly as possible, you’ll need to use a 220-volt outlet.
The second factor is the distance from the power source. The closer your charger is to the power source, the faster it will charge. This is because the electrical current has less distance to travel, and there is less resistance along the way.
The third factor is the type of cable used. A standard copper cable will charge a 7.2 kW charger much slower than a specialized charging cable. Specialized charging cables are designed to minimize resistance and maximize flow of electricity. You’ll need to use a specialized charging cable if you’re looking to charge your 7.2 kW charger as quickly as possible.
The fourth factor is the ambient temperature. Cold temperatures can cause the battery in your 7.2 kW charger to lose some of its capacity, which will, in turn, affect its charging speed. If you’re looking to charge your 7.2 kW charger as quickly as possible, you’ll need to ensure that it’s in a warm environment.
All of these factors play a role in determining how fast a 7.2 kW charger will charge. By considering all of these factors, you can ensure that your charger charges as quickly as possible.
Summary
In conclusion, no single answer is how much range you get per hour of charging for 7.2 kW. The answer depends on various factors, from the type of electrical outlet to the ambient temperature. However, by considering all of these factors, you can ensure that your charger charges as quickly as possible.
