What Is Bidirectional Charging? Understanding the Benefits for Both Drivers and Businesses

EV Connect

These exciting new capabilities are catching the eye of automakers and EV charging manufacturers, and many have already made this type of charging available to consumers or plan to do so in the near future. This conversion can happen within the charger or in the vehicle, depending on which device is equipped with a converter.

DOE to Award Up to $27M in Phase III Small Business Awards; Algae Processing, Fuel Cells, Improved Materials for Motors, Synthetic Fuels Among Areas of Interest

Green Car Congress

Additionally, few of current harvesting and dewatering technologies available today are amenable to scaling for larger production scenarios of 1,000 acre or larger algal farms. Algae cultures tend to be relatively dilute, and the energy requirement to remove water from the cultures can be a significant portion of the energy balance.

How to improve EV traction motor efficiency

Charged EVs

The vast majority of losses in an ICE vehicle occur in the conversion of chemical energy to mechanical—the so-called Carnot Efficiency—which might approach 40% in the best of cases. The CVT4EV is a continuously variable transmission with a pushbelt that Bosch says can increase the efficiency of light commercial EVs by more than 4 percent.
