How It Works: Tomorrow s Hybrid

A concept from Volvo the power inside the wheels for efficiency and extra mileage


A look inside the motor contained within wheel

The ReCharge, Volvo’s concept hybrid, could squeeze 160 from a gallon of gas by tossing out the transmission. It packs a small motor inside each so that no power is lost in the Here’s a look at the next of fuel-efficiency

How Wheel Motors Drive the Car

electric motors directly the wheels eliminates the transmission, typically wastes 10 to 20 percent of the energy. An interior disc . to the wheel bearings, contains a of independently controlled electromagnets . emit a magnetic field in to an electrical current. Around an outer ring contains magnets . Step on the accelerator, and a in the interior ring begins to switch the polarity of the electromagnets, or attracting the permanent magnets.

The faster the polarity changes, the the motor spins the wheels.

The is controlling four independent one spins even slightly the car could veer violently. The team’s next big hurdle is the software that maintains control. As for performance, the car will permanent all-wheel drive no gearbox standing between foot and the motors—in other it should go like a rocket.

Batteries power all four and the car’s electronics. Unlike plug-in hybrids, the ReCharge a lithium-polymer (rather than battery. This is not only uses sheets of plastic of a volatile electrolyte solution—but it powers the car for 60 miles before the kicks in to recharge it.

Small batteries have started to up in gadgets such as the iPhone, but gets its larger, experimental from an undisclosed manufacturer.

The engine charges the battery the car isn’t plugged in. The concept calls for either a 1.6-liter or turbodiesel engine, but since the doesn’t have to actually a drive shaft, a fuel or a second battery could do the job as well. It would kick in to the battery only after the was at 30 percent capacity, so the ReCharge travel 160 miles on a single of gas.

A charger feeds power to the when the car is plugged in at home. the ReCharge will be equipped an intelligent version that can sense strain in your electrical grid and either cut its power consumption or feed from its battery back the system.

Tires must be as as possible since the motor each wheel bigger.The uses specially designed tires with a soft, surface that also rolling resistance.
