Flat-towing electric vehicles (EVs) poses unique challenges compared to traditional internal-combustion vehicles. Automakers are developing innovative methods to address these issues, ensuring safer and more efficient towing processes. Stellantis has proposed a patent that utilizes a high-voltage bus to reduce motor torque in EVs with permanent-magnet synchronous motors. This allows the wheels to rotate more freely without damaging components. Meanwhile, Rivian's approach involves software disconnection of rear motors while maintaining torque on front wheels. Ford’s earlier patent suggests selective charging during towing, which could also assist the tow vehicle in challenging terrains. These advancements aim to enhance convenience for RV owners and improve recovery options for stranded EVs.

Stellantis' High-Voltage Bus Solution for Enhanced Towing

The automotive industry is addressing the complexities of flat-towing electric vehicles through advanced engineering solutions. One notable example comes from Stellantis, which has introduced an innovative method to facilitate this process. By employing a high-voltage bus system, Stellantis aims to induce field weakening in the motors of EVs equipped with permanent-magnet synchronous motors. This reduces the torque, allowing the wheels to spin more freely while isolating them from the battery pack. This solution simplifies the towing procedure and minimizes potential damage to mechanical parts.

This patented idea represents a significant advancement in EV technology. Traditionally, internal-combustion vehicles can be easily flat-towed by shifting into neutral or disconnecting the prop shaft. However, EVs present a different challenge due to their complex motor-wheel coupling. Stellantis’ method offers a practical alternative, making it easier for drivers to tow their EVs without risking component failure. The high-voltage bus system ensures that the motor remains operational but operates at a reduced torque level, providing a safer and more reliable towing experience. Additionally, this innovation could benefit RV owners who frequently need to tow vehicles, enhancing overall convenience and safety on the road.

Software-Driven Innovations in EV Towing

Rivian and Ford have each contributed unique approaches to improving the flat-towing capabilities of electric vehicles. Rivian’s patent focuses on using software to manage motor disconnection during towing. Specifically, the rear motors are disconnected while torque is applied to the front wheels, preventing the vehicle from rolling out of sync with the tow vehicle. This software-driven solution provides precise control over the vehicle’s movement, ensuring smoother and safer towing operations.

Ford’s earlier patent takes this concept further by introducing the possibility of selective charging during towing. This not only keeps the EV’s battery charged but also enables the vehicle to assist the tow vehicle in difficult terrains, such as uphill climbs. Such innovations open up new possibilities for enhancing the utility and efficiency of electric vehicles. For instance, startups like Pebble and Lightship have already integrated similar features into travel trailers. These advancements underscore the importance of continuous innovation in the automotive industry, particularly for applications that were previously overlooked. Ultimately, these solutions could make flat-towing more accessible and beneficial for a wider range of users, including RV enthusiasts and those needing to recover stranded EVs.

The recent decision by President Donald Trump to halt all new funding under the National Electric Vehicle Infrastructure (NEVI) Formula Program has sparked significant debate. Established by the 2021 bipartisan infrastructure law, this program was designed to allocate $5 billion in federal funds to states for the construction of 500,000 electric vehicle charging stations by 2030. Pennsylvania, for instance, had been allocated $171.5 million over five years to develop a strategic network of charging stations. The suspension of these funds not only jeopardizes the expansion of EV infrastructure but also raises concerns about the competitive landscape of the industry. Critics argue that this move could benefit established companies like Tesla at the expense of smaller firms and consumers.

The NEVI program was intended to empower states to shape their own future by building reliable electric vehicle infrastructure. In Pennsylvania, the allocation of funds aimed to enhance valuable roadways with dependable charging stations, attracting visitors and residents alike. Lawmakers from both parties welcomed the initial funding, encouraging applications for the program. However, the sudden stop order has cast doubt on the administration's commitment to clean energy initiatives. Many see this as a reflection of Trump's well-documented preference for traditional energy sources like oil and gas.

Some observers fear that halting new EV charging station growth serves another agenda: reducing competition for Tesla and its CEO, Elon Musk. Without the NEVI program, numerous companies across the country are being denied crucial seed funding to establish themselves, create local jobs, and participate in market competition. This loss could tilt the playing field further in Tesla's favor. Musk himself acknowledged this, tweeting that ending subsidies "will only help Tesla."

The consequences extend beyond corporate interests. Consumers who stand to benefit from a broader, more accessible EV infrastructure network will also be affected. Tesla's Supercharger network already dominates the market, requiring other automakers and electric companies to either partner with Tesla or build their own networks. Cutting off these networks is seen as an unfair development. Musk's control over key sectors like EV infrastructure, space exploration, and communications positions him to align federal policies with his business interests, potentially disrupting the principles of competition and opportunity.

The NEVI program once offered opportunities for local companies like Wawa and Sheetz to compete alongside Tesla. While Tesla's head start ensures its survival, the same cannot be said for emerging players. As the ladder of opportunity is pulled up, it becomes clear that capitalizing on loss is a strategy favored by billionaires and their corporations. The suspension of the NEVI program underscores the need for balanced policies that foster innovation and fair competition in the evolving electric vehicle market.
