Ford has filed a patent for a roof-mounted backup EV battery system that could give electric vehicles extra range while off the grid. The idea is still early, but it shows how automakers are getting creative in the electric era.
Challenges
There are a few challenges that Ford would need to overcome to make this system practical.
- First, the battery must be lightweight enough to be easily removable and heavy enough to provide a significant range boost.
- Second, the vehicle’s roof would need to be reinforced to support the weight of the battery. Finally, the system would need to be affordable, as it would likely be an aftermarket accessory.
Overall, the idea of a roof-mounted backup EV battery system is intriguing, but it remains to be seen whether it will ever be a practical reality.
Here are some of the pros and cons of this system:
Pros:
- Will provide a significant range boost for electric vehicles
- To be used in remote areas where there are no charging stations
- Could be removed and stored when not needed
Cons:
- Will be heavy and could affect the handling of the vehicle
- Expensive
- Would require the roof of the vehicle to be reinforced
Given these practical challenges, some users have suggested alternative solutions. One idea is to explore the development of solar modules that can be integrated into the roof of vehicles. This approach as demonstrated by ABT’s work with the VW ID. Buzz would provide a more practical way to generate different ranges while off the grid without heavy rooftop batteries.
Benefits of a roof-mounted backup EV battery:
- Increased range: A roof-mounted backup battery could provide a significant range boost for electric vehicles, allowing them to travel further without recharge. This could be especially helpful for people living in rural areas or frequently travelling long distances.
- Flexibility: A roof-mounted backup battery could be removed when not needed, making it more practical for people living in areas with limited charging options. For example, if you only need the extra range for a long road trip, you could remove the battery and store it in your garage when you get home.
- Customization: The battery could be modular, so it could be customized to fit the needs of different vehicles. For example, a truck owner might want a larger battery than a car owner.
Conclusion
In summary, while Ford’s roof-mounted backup EV battery system may seem attractive, some significant practical considerations and challenges must be addressed before it becomes a viable and safe option for electric vehicle owners.
