Electric vehicles (EVs) have become increasingly popular over the years as more and more people become environmentally conscious. As the demand for these cars continues to grow, EV owners need to know the best ways to keep their vehicles charged. One way to do this is by using a generator. But what size generator can charge an EV properly? In this article, we’ll explore the answer to this question in detail.
Understanding EV Charging Levels
Before we talk about the size of the generator needed to charge an EV, it’s essential to understand different EV charging levels. Knowing these levels will help determine the generator size you need.
Level 1 chargers are standard 120V outlets, which can charge an EV overnight. However, the charging rate is relatively slow, and it can take up to 20 hours to charge most EVs.
Level 2 chargers require a 240V outlet and can charge an EV twice as fast as a Level 1 charger. Most EV owners install a Level 2 charger at home or work.
Finally, Level 3 chargers, also known as DC Fast chargers, are rarely found in homes or workplaces. They can charge an EV battery up to 80% in just half an hour.
Generator Size Required to Charge an EV
When it comes to charging an EV with a generator, the most crucial factor is its power output capacity. The generator’s power output must match the charging rate of the EV’s charger.
A typical EV charger operates at 240V and can draw around 30-40 amps (depending on the charger’s model). This means the generator needs to have a power output of at least 7.2kW to 9.6kW (240V x 30amps = 7200 watts or 240V x 40amps = 9600 watts). A generator with this power output should charge an EV battery as fast as a Level 2 charger.
Selecting the Right Generator
Choosing the right generator to charge your EV can be a daunting task. You’ll need to consider factors like power output, portability, and noise levels, among others. Here are some of the most crucial factors to consider when choosing a generator for your EV:
- Power Output: As mentioned above, you’ll need a generator with a power output of at least 7.2kW to 9.6kW.
- Portability: Consider how portable you need the generator to be. If you plan to use it at home only, then it may not matter if it’s not very portable. On the other hand, if you travel often and need a generator to charge your EV, then you’ll need one that’s easy to move around.
- Noise Levels: Generators can be loud. If you’ll be using your generator at home, you’ll want to look for one that’s quiet enough, so it doesn’t disturb your neighbors.
- Fuel Type: Generators come in various fuel types, including gas, diesel, propane, and solar. Each fuel type has its pros and cons, so you’ll need to choose one that meets your needs.
Conclusion
A generator can be a great alternative way to charge your EV, especially when you’re on a road trip or camping. However, you need to make sure you have the right size generator that matches the charging rate of your EV charger. With the information provided above, you should be able to choose the right generator to meet your needs.

Frequently Asked Questions (FAQs) for What Size Generator Can Charge An EV?
1. Is it possible to charge an electric car using a generator?
Yes, it is possible to charge an electric car using a generator. However, the generator must have a sufficient output capacity to meet the electric car charging demands.
2. What size generator do I need to charge my electric car?
The size of the generator needed to charge an electric car depends on several factors such as the type of electric car, the battery size, and the charging speed required. In general, an electric car requires about 240 volts and 30 amps to charge at a rate of 7.2 kW. Therefore, a generator with a minimum output capacity of 7.5 kW should be sufficient to charge most electric cars.
3. Can I charge my electric car using a portable generator?
Yes, you can charge your electric car using a portable generator. However, you need to ensure that the generator has enough capacity to meet the charging demands of your electric car. Also, you need to make sure that the generator is placed in a location that allows for proper ventilation and is away from any flammable materials.
4. Can I use solar panels to charge my electric car instead of a generator?
Yes, you can use solar panels to charge your electric car instead of a generator. Solar panels can generate electricity that can be used to charge your electric car. However, the amount of time it takes to charge your electric car using solar panels depends on the size of the solar panels, the battery capacity of the electric car, and the charging speed required.
