Keep up your EV’s solar panel rolled up in the trunk

Roll-up solar panel EV patent

Filed: January 31, 2017; Published: August 3, 2017

Patent says: “When the sheet-shaped solar battery is used to perform electric power generation, the sheet-shaped solar battery is taken out of the storing portion and then spread to effect photovoltaic power generation.”

What this might mean: You know those people who put a reflective sun shield in their window to try and keep the cabin cool while the car is parked? If you’re one of them, then you’ll love a new idea for solar power charging your electric vehicle from the Disco Corporation out of Japan. Basically, when you want to get some solar energy into your EV’s battery, you simply open the trunk, unroll a solar sheet, and put it in a sunny space with a cord connected to the car. As the patent says, since the sheet can be big, “compared with the case of mounting a solar panel on the roof or hood of the vehicle body, larger electric power can be obtained.” What’s most bizarre about this patent, though, is the idea that you might have the charging sheet dragging behind you as you go down the road. To wit: “the sheet-shaped solar battery is spread on the back side of the electric vehicle so as to come into contact with a road surface.” Maybe Disco should talk to Toyota about its sun-following nav system.

Ford wants to charge your EV … and your electric bike

Ford Electric Bike Charger

Filed: April 20, 2017; Published: August 3, 2017

Patent says: “The electric bicycle may be stowed in the electric vehicle, and the electric vehicle may charge the electric bicycle via a common charging interface. Moreover, the electric vehicle may include a system that has a processing device programmed to determine a state of charge of the vehicle battery and the bicycle battery. The processing device further estimates traveling ranges of a vehicle and a bicycle based on the states of charge. A navigation module may be programmed to generate a route to the destination based on the estimated traveling ranges of the vehicle and the bicycle.”

What this might mean: Storing your electric bike in your electric car, and having both charge at the same time when the EV is plugged in is a really cool idea. Ford has taken this one step further to have the nav system tell you, “hey, park here and bike the rest of the way because traffic is a bear,” is an even cooler idea. Letting the EV battery throw some electrons into the bike’s battery while you’re driving down the road, if need be, just puts the cherry on top.

Yokohama puts a little wind turbine inside your tire

Yokohama Energy Generating Tire

Filed: May 12, 2015; Published: August 3, 2017

Patent says: ” The power generation system comprises: a pneumatic tire; a wheel on which the pneumatic tire is mounted; and at least one generator wind turbine attached, in a cavity defined by the pneumatic tire and the wheel, to the pneumatic tire and/or the wheel.”

What this might mean: Just look at that patent image for a minute. While I assume that Yokohama isn’t actually going to put a miniature wind turbine – one shaped like the big ones you see in fields or on the water sometimes – into your tire, the image above is precious. Somehow, Yokohama thinks that it makes sense to try and capture some of the kinetic energy of the car moving down the road with a little turbine hidden in your tire. Yokohama is thinking about EVs with this concept, of course, saying that,  the energy from the turbine could go to a “rechargeable battery that stores electric power,” but the patent is frustratingly vague about how efficient or practical something like this could be. Then again, that’s kind of the point of a patent filing, to capture an idea for the future.

I think April Fools’ Day came late this year!

What are they thinking? The whole point of my electric assist bike is to be able to ride anywhere I want to go, without using the car.

IP with no I is just P.’d..destroy..1-2..generator wind turbine’S..e.ventually.

Looks like Yokohama didn’t get the memo about conservation of energy.

Rolled up solar panels is not a new idea. It is stupid to grant a patent just because no one has patented the idea of carrying it around in the trunk of your car. Patent laws do not require your patent to be useful, functional, or a unique idea, only that it has not been patented before. However, now that it has been granted, if you roll up a solar panel and carry it in your trunk, you will have to pay him royalties.
