How Long Does Hummer EV Take to Charge?

Are you considering purchasing a Hummer EV but wondering about the charging time? The design of electric vehicles has come a long way, and the Hummer EV is no exception. With its advanced charging technology, this electric powerhouse can get you back on the road in no time. In this article, we will dive deep into the charging capabilities of the Hummer EV, exploring the different factors that affect charging time and the charging options available to users. So let's get started and explore how long it takes to charge a Hummer EV.

Understanding Charging Time for Electric Vehicles

Charging time is a crucial aspect to consider when purchasing an electric vehicle. It directly impacts the convenience and usability of the vehicle, especially during long trips or when you have limited charging options available. The charging time of an EV is influenced by various factors like the battery size, charging method, and the power output of the charging station. In the case of the Hummer EV, it offers an impressive charging capability that ensures you spend more time on the road and less time waiting to recharge.

The Impact of Battery Size

The battery size of an electric vehicle plays a significant role in determining the charging time. Generally, EVs with larger battery capacities take a bit longer to charge compared to those with smaller batteries. The Hummer EV boasts a robust battery pack, ensuring you have ample power for your adventures. However, due to its larger battery size, it necessitates a sufficient charging time.

The Hummer EV is equipped with Ultium batteries, developed by General Motors specifically for their electric vehicles. These advanced batteries offer a remarkable range and can store a substantial amount of energy. While the exact battery size of the Hummer EV may vary based on the chosen configuration, it typically has a range of up to 350 miles per charge.

The Fast Charging Superpower

One of the key highlights of the Hummer EV is its fast-charging capability. It features General Motors' Ultium Charge 360 technology, allowing for rapid charging speeds and minimizing downtime. With the Hummer EV, you can enjoy the convenience of faster charging, reducing your wait time and making long trips more feasible.

Using a DC fast charger, the Hummer EV can charge from 10% to 80% in as little as 45 minutes. This rapid charging capability is made possible because the Hummer EV supports up to 800-volt DC fast charging, delivering power at an astonishing rate. With this impressive charging speed, you can take short breaks during your journey and achieve a significant charge boost, extending your driving range to continue your adventure.

Charging Options for the Hummer EV

In addition to its exceptional fast-charging capabilities, the Hummer EV offers various charging options, enabling you to recharge your vehicle conveniently. Let's explore some of the different charging options available for the Hummer EV:

1. Home Charging

Home charging is the most convenient way to charge your Hummer EV, especially when you have the time to plug it in overnight. With a Level 2 charger, which typically operates at 240 volts, you can conveniently charge your Hummer EV from the comfort of your own home. The charging time will vary based on the battery level and the power output of your home charging station.

While the exact charging time may differ based on various factors, the Hummer EV can roughly gain about 12 to 15 miles of range per hour of charging with a Level 2 charger. Therefore, if you have drained your battery completely, it may take around 24 to 28 hours to reach a full charge using a home charging station.

2. Public Charging Stations

When you're on the go and need a quick charge, public charging stations are lifesavers. The Hummer EV is compatible with various public charging networks, making it convenient to charge your vehicle wherever you are. These charging stations can be found at shopping centers, parking lots, or along major highways.

Public charging stations typically offer Level 2 chargers or DC fast chargers. Level 2 chargers, operating at 240 volts, can replenish the Hummer EV's battery at a similar rate to home charging stations, providing approximately 12 to 15 miles of range per hour of charging.

On the other hand, DC fast chargers, commonly known as quick chargers, are the fastest public charging option available. With their high power output, they can significantly reduce charging time. As mentioned earlier, the Hummer EV can charge from 10% to 80% in just 45 minutes when using a compatible DC fast charger.

3. The Electrify America Network

As part of General Motors' commitment to expanding the charging infrastructure for electric vehicles, they have partnered with Electrify America. This collaboration unlocks a world of charging possibilities for Hummer EV owners, offering access to a vast network of fast-charging stations across the United States.

Electrify America stations commonly provide a power output of up to 350 kW, ensuring optimal charging speeds for the Hummer EV. With such high power capabilities, you can expect to achieve a significant charge in a short amount of time.

4. Home Battery Storage

Another innovative charging option for the Hummer EV is home battery storage. By utilizing home battery systems, such as the GM-licensed Wallbox Copper SB, you can store excess energy generated by your solar panels or take advantage of off-peak electricity rates for charging your vehicle.

Home battery storage systems provide a more sustainable approach to charging your Hummer EV by utilizing renewable energy sources. While the exact charging time will depend on the capacity of the home battery system, it adds an extra layer of convenience and eco-friendliness to your charging routine.

5. Charging Adapter for Other Networks

The Hummer EV also offers a robust onboard charging system that provides flexibility in various charging scenarios. It comes equipped with a universal charging port, allowing you to connect to different types of charging stations with the appropriate adapter.

In the case of charging networks that use different charging standards, such as Tesla's Supercharger network, adapters can be used to connect your Hummer EV to these stations. These adapters ensure compatibility, giving you access to a wider range of charging options whenever needed.


In conclusion, the charging time of the Hummer EV depends on several factors, including the battery size, charging method, and power output of the charging station. With its fast-charging capabilities, the Hummer EV can charge from 10% to 80% in as little as 45 minutes using a DC fast charger.

The Hummer EV offers various charging options, including home charging, public charging stations, the Electrify America network, home battery storage, and the ability to adapt to other charging networks. These charging options provide flexibility and convenience to Hummer EV owners, ensuring they can recharge their vehicles easily, wherever they may be.

So if you're looking for an electric vehicle that combines power, capability, and fast-charging technology, the Hummer EV is certainly worth considering. With its impressive charging capabilities, you can spend more time enjoying the open road and less time waiting by the charging station.
