Ford Files Patent for a Roof-Carried Spare EV Battery


  • Ford lately filed a patent for an backup battery pack that EV house owners can carry alongside so they do not have to fret a lot about vary.
  • The battery, proven housed on the roof of the automotive, incorporates battery modules, a backup battery meeting, and a connection port to maximise ease.
  • The patent photographs use a Ford Bronco because the demo automotive. Might an electrical Bronco be nearer than we predict? Both manner, this invention might be not coming quickly.

There are two issues we all know to be true in regards to the EV market: Automakers need to promote the adoption of electrical automobiles, and customers are nervous about vary. Now, as first reported by Electrek, Ford has utilized for an progressive patent for a backup battery pack that may journey on the roof of the automobile. This patent seems like a novel solution to deal with the vary nervousness and charging considerations that individuals usually affiliate with EVs, particularly on prolonged journeys. One suggestion within the patent software is that these battery packs may very well be “rented or leased previous to an off-roading journey, for instance.”

The patent outlines a mechanism designed to supply extra energy and vary to EVs when the first battery is depleted. It is a modular system that is supposed to be appropriate throughout completely different EV fashions and, no less than based on the outline, easy to keep and improve. The models are stacked to supply probably the most capability.

Past the truth that a roof-mounted battery pack is sitting on high of the automobile in these drawings, it is attention-grabbing that the automobile used resembles the Ford Bronco. We surprise if it is a trace that an EV model of Ford’s big-selling Bronco is coming quickly.

So Many Questions

However we, like others, have questions, principally: How does Ford plan on reinforcing the roof to deal with the load? A rack cannot do it alone. And the way does the battery stand up there (and down once more)? EV battery packs’ weight can vary into the hundreds of kilos.

The patent software explains that the battery is detachable, which leads us to consider this roof-mounted pack will not have the capability of the massive packs automakers use to energy their EVs. This ought to make sure the pack weighs only a couple hundred kilos—a sum most roof racks are able to holding. For example, the unique Prius plug-in hybrid’s 4.4-kWh battery hit the scales at a manufacturer-claimed 176 kilos.

That does not imply it’s going to be straightforward to hoist a battery pack in your EV or PHEV’s roof. Anybody who’s ever used a roof-mounted cargo service can inform you that you simply’d doubtless want no less than one different individual to help with this job.

Assuming our hunch is appropriate, then we predict the potential product this patent hints at will serve the equal goal of a fuel automotive’s reserve tank. That mentioned, given the additional weight and damaging results on aerodynamics the extra pack can have on an EV, it is attainable this idea really worsens an EV’s vary, significantly at freeway pace.

At decrease speeds, although, similar to in off-road environments, this roof-mounted battery pack could provide the little bit of additional juice wanted to get again to the trailhead. Including a set of photo voltaic panels may make this idea even higher, as they’d permit the roof-mounted pack to—slowly—replenish itself, too.

It appears evident that this invention just isn’t going to grow to be a actuality anytime within the close to future. It have to be a placeholder for a future time when Ford has the fitting electrical off-road automobile to make use of it with—and, extra necessary, when battery expertise has superior sufficiently that the load just isn’t a difficulty anymore.
