As she drives her electric vehicle to her mother’s house, Monique’s battery gauge indicates that it’s time to reenergize. Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). This battery, though, uses a completely new kind of fluid, called a nanoelectrofuel.

Volkswagen marked its serious entry into the battery-electric vehicle market with the introduction in Frankfurt of its first two series production EVs: the e-up! The electric motor’s power is transferred to the front wheels via a single-speed gearbox. Volkswagen itself developed all of the components, including the battery.

After debuting the first solar air battery—a photo-assisted charging Li-O 2 battery—last fall ( earlier post ), researchers at The Ohio State University led by Professor Yiying Wu have now developed a new system combining a solar cell and a battery into a single device.

As one point of comparison, customers bought 54,451 Nissan LEAFs EVs in fiscal year 2017—a 15% increase from 47,423 a year earlier. Contracts with the battery suppliers have been signed. The power electronics are effectively a link that controls the flow of high-voltage energy between the motor and the battery.

Fuel Cell Electric Vehicles (FCEV) are similar to BEVs in that they have an electric-only powertrain, but they store energy differently. FCEVs store hydrogen gas in a tank rather than charging a battery. The fuel cell’s electricity then powers an electric motor, which drives the vehicle like a BEV. Conclusion.

This renewable production capacity is increasingly important to ensure the existing power grid can accept more renewable sources. Myth #2: Hydrogen gas is dangerous to store and use. Of course, this also has the merit of producing so-called “green hydrogen”. Myth #5: FCEVs don’t have enough energy for long journeys.
