Ford unveils C-MAX Solar Energi concept; “plug-in” hybrid not dependent on electric grid can fully recharge from sun

Green Car Congress

Ford’s C-MAX Solar Energi concept combines a rooftop solar panel with an off-board solar concentrator—essentially an inexpensive Fresnel lens canopy. Ford C-MAX Energi gets a combined EPA-estimated 108 MPGe city and 92 MPGe highway, for a combined 100 MPGe. Ford C-MAX Solar Energi Concept. Click to enlarge.

Why is maintaining 80% battery power the best choice for EVs? | EV Basics

Setec Powerr

Why is 80% battery capacity the optimal choice? Instead of batteries taking in energy at a constant, predictable rate, the rate changes based on myriad variables, though most notably the battery’s state of charge. The fuller the battery is, the slower it absorbs energy. Charging is not linear.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Lead author Aniruddh Mohan and colleagues wanted to develop a method that evaluated the life-cycle costs and benefits for two battery-powered ridesource fleets and a gasoline-powered one. The analysis indicated that electrified fleets had 40-45% lower greenhouse gas costs per trip compared to the gasoline-powered version.

Tech: How do Hybrid & Plug-in Hybrid Batteries Recharge? Do I Need to Plug a Hybrid In?

Clean Fleet Report

Regular Hybrids Regular hybrids recharge their onboard nickel-metal hydride or lithium-ion battery packs by reclaiming energy through a process called regenerative braking. In addition, when in the generator mode, the internal combustion (usually gas) engine charges the battery pack. Do I Need to Plug a Hybrid In?
