As the electric vehicle (EV) market continues to expand, many drivers wonder about alternative charging solutions beyond the traditional charging stations. One intriguing question that arises is: can you actually charge an electric car with a generator?
The answer is yes, you can charge an electric car with a generator, but it’s not as simple as plugging your car into any generator you have lying around. Here’s a detailed breakdown of the feasibility, challenges, and considerations involved in using a generator for EV charging:
1. Can I Charge an Electric Car with a Generator?
Technically, yes, you can use a generator to provide the necessary electrical power to charge your EV. However, several factors need to be carefully considered before attempting this method:
- Generator Size: Most portable generators available for consumer use lack the sufficient power output to effectively charge an EV battery. Electric car charging typically requires a minimum of 10 kilowatts (kW) of power, significantly exceeding the capacity of most portable generators.
- Charging Time: Even with a powerful enough generator, charging an EV through this method can take significantly longer compared to utilizing a dedicated charging station.
- Safety Precautions: Using a generator for EV charging requires proper grounding and safety measures to prevent electrical hazards.

2. Why Would You Want to Charge an Electric Car with a Generator?
While using a charging station remains the primary and most efficient method for charging EVs, there are a few scenarios where a generator might be considered:
- Charging Stations Aren’t Everywhere: In remote areas or during power outages, access to charging stations might be limited. A generator can provide a temporary solution to maintain your EV’s range.
- Charging Stations Might Be Inaccessible: Certain situations, like camping trips or off-grid adventures, might necessitate alternative charging methods where a generator becomes the only viable option.

3. The Challenges of Charging An Electric Car With A Generator:
Despite the technical possibility, using a generator for EV charging presents several challenges:
3.1. Small Generators Are Too Weak:
Most portable generators commonly used for household purposes have power outputs ranging from a few kilowatts to around 10 kW. This falls short of the minimum requirement for efficiently charging an EV battery.
3.2. Big Generators Are… Well, They’re Big:
Generators capable of providing sufficient power for EV charging are typically large, industrial-grade units. These generators are often expensive, require specialized installation, and have significant fuel consumption rates.

4. How Long Does It Take to Charge a 12v Battery with a Generator?
While the focus lies on charging EV batteries with high capacities, it’s worth noting that charging a standard 12v battery with a generator is possible. The charging time depends on several factors:
- Generator Power Output: A higher power output from the generator translates to faster charging times.
- Battery Capacity: Larger batteries naturally take longer to charge compared to smaller ones.
- Charging Rate: The specific charging rate of your battery charger also influences the charging duration.
As a general rule, charging a 12v battery with a powerful generator can take anywhere from 30 minutes to a few hours, depending on the factors mentioned above.
5. Conclusion:
While technically possible, using a generator for EV charging presents practical limitations. The insufficient power output of most portable generators and the extended charging times compared to dedicated stations make it a less than ideal solution for everyday charging. However, in emergency situations or remote locations where charging stations are unavailable, a generator can provide a temporary means to maintain your EV’s range. As EV technology continues to evolve and charging infrastructure expands, relying on generators for regular charging is likely to become less necessary.
