GMC Hummer EV And Hummer SUV Claim The Highest Charging Power

The GMC Hummer EV and Hummer EV SUV have a split battery pack enabling 400 Volts of operation while driving and 800 Volts while stationary to enhance charging speed. They support up to 350 kW charging. In real world conditions, they can add 100 miles of range in 12 minutes using a powerful Level 3 DC fast charger, though GMC claim this figure to be as low as 10 minutes.

The Hummer EV Benefits From GMC’s New Ultium Innovation

Ultium is General Motors’ advanced battery technology platform designed for electric vehicles. This innovative system features modular battery cells that can be configured in various sizes and shapes to accommodate a wide range of vehicle designs. Ultium batteries use large-format, pouch-style cells, which can be stacked vertically or horizontally inside the battery pack, allowing for flexibility in vehicle engineering and improved energy density. The platform supports fast charging, enhanced range, and reduced costs, making it a cornerstone of GM’s strategy to lead in the electric vehicle market.

The Ultium architecture integrates batteries with Ultium Drive units, which include the traction motors, reduction gear, and power electronics into a single unit that drives the front, rear, or both axles. This system’s flexibility extends to its use of three electric motor designs, sharing a common stator, across various vehicles. The motors are oil-cooled and suitable for front-wheel drive, rear-wheel drive, and all-wheel drive configurations. The drive units are designed with a single-speed reduction gearbox and integrated electronic control modules, contributing to a reduction in mass and complexity.

The Ultium battery cells feature a nickel-cobalt-manganese-aluminum (NCMA) chemistry, enhancing energy density and reducing costs. These cells are produced by Ultium Cells LLC, a joint venture between GM and LG Energy Solution, and are designed to offer significant flexibility in vehicle applications. GM’s innovative wireless battery management system (wBMS) further reduces costs and complexity by requiring 90-percent less wiring and reducing the battery pack’s volume by 15-percent.

The Ultium platform is not only central to GM’s vehicle lineup but is also being deployed in collaboration with other brands like Honda and Acura. GM’s future electric vehicles, such as the GMC Hummer EV, Cadillac Lyriq, and Chevrolet Silverado EV, leverage the Ultium platform for its advanced features. GM’s commitment to this technology is evident in its substantial investments in production facilities, including multiple plants in the United States and a factory in China, ensuring a robust supply chain for the Ultium batteries and drive units.

GMC Is At The Forefront Of Fast-charging Evolution

The growing urgency to transition to sustainable energy sources and mitigate the effects of climate change has spurred increased institutional support for electric transportation. Governments, nonprofits, and businesses are ramping up their efforts to develop a sustainable economy, offering incentives such as state and federal tax credits for installing EV charging stations.

Corporations like GMC are also making significant commitments to the EV charging landscape, with plans to build nationwide charging networks. This institutional support further accelerates the growth and adoption of electric vehicles and EV charging infrastructure, signaling a significant shift toward cleaner and more sustainable transportation options.

The Surge of Fast Charging in the U.S.

Fast charging technology has revolutionized the EV charging landscape, making electric vehicles more practical and convenient for a broader range of users. With the ability to recharge 60 to 80-miles worth of driving in well under 20 minutes, fast-charging stations are becoming increasingly common.

In 2019 alone, over 130,000 fast-charging stations were installed globally, and this number is expected to nearly double by 2025, reaching nearly 227,000 stations. This surge in fast-charging infrastructure not only addresses the need for quicker charging times but also contributes to the integration of EV charging into various societal environments.

Key Information

• From 17,000 electric cars on roads worldwide in 2010 to 7.2 million in 2019, there’s been a 42,000% increase in electric vehicles
• Newer direct-current, fast-charging technology allows for recharging 60 to 80-miles worth of driving in under 20 minutesInitiatives include state and federal tax credits for EV charging stations and corporations like General Motors committing to building nationwide EV charging networks
• The Hummer EV offers two battery sizes: a standard 20-module pack and an optional 24-module pack. The larger pack is said to provide up to 381 miles of range per charge
• Opting for the Extreme Off-Road package can reduce the estimated range, as it adds features like beadlock-capable 35-inch mud-terrain tires and extra underbody armor

The Other Fast-Charging EVs

Lucid Motors is engaging in a fierce competition with GMC over who can offer the highest charging power for their electric vehicles. The battleground is set around the maximum charging speed, a crucial factor for EV buyers looking for quick replenishment of their vehicle’s battery.

Lucid Air Is The Highest Voltage EV On Sale

Lucid Motors, with its flagship model, the Lucid Air, boasts the highest-voltage EV currently on sale in the US. The Lucid Air runs at over 900 volts, enabling impressive charging speeds of up to 300 kW in its top Grand Touring and Sapphire trims. This translates to gaining up to 200 miles of range in just 12 minutes, making it a compelling option for those seeking fast charging capabilities.

Other Fast Charging EVs

Chevrolet Silverado EV Matches The Hummer EV’s Charging Speed

On the other hand, Chevrolet’s Silverado EV, which is owned by General Motors, is not far behind. Like the Lucid Air, the Silverado EV utilizes a unique battery pack configuration, with two separate 400-volt packs. Through innovative engineering, Chevrolet manages to double the voltage during charging, reaching a maximum charging speed of 350 kW. This allows the Silverado EV to add up to 100 miles of range in as little as 10 minutes, matching the performance of the GMC Hummer EV.

GMC Hummer EV vs. Chevrolet Silverado EV vs. Lucid Air

The Hummer EV, with its DC fast charging capacity of 350 kW, stands among the top-tier electric vehicles for rapid charging capabilities. Its speed matches that of the Silverado EV, another model utilizing the Ultium lithium-ion battery, which suggests a parity in the fast-charging infrastructure provided by their shared technology. Despite the Silverado EV’s potentially larger gross battery capacity (“over 200 kWh” compared to Hummer’s 210 kWh), both vehicles promise robust charging rates.

In comparison, the Lucid Air Sapphire offers a slightly lower DC fast charging capacity at 300 kW. However, the Lucid compensates for this with a significantly higher MPGe (105 MPGe vs. Hummer’s 53 MPGe) and lower energy consumption (32 kWh/100 miles vs. Hummer’s 63 kWh/100 miles), which also contributes to its longer estimated range of 427 miles.

While the Hummer EV excels in charging power, its efficiency is noticeably lower than the Lucid Air Sapphire. This is partly due to its considerable weight (9,039 pounds), which likely contributes to its higher energy consumption and lower overall range (314 miles). Therefore, while the Hummer EV and Silverado EV offer some of the fastest charging speeds available, the Lucid Air Sapphire remains competitive due to its superior efficiency and range, despite a slightly lower fast charging capability.
