Behold, The Cleanest EVs On The Road. Why Aren’t Banks Jumping On This?

CleanTechnica EVs

In a previous article series, I compared the lifetime emissions of various real EVs and PHEVs on the road, as well as several hypothetical EVs. I even compared power sources (renewables vs. dirtier grids) to see how that all stacks up.

Advanced Propulsion Centre UK publishes automotive power electronics value chain

Green Car Congress

A DC-DC converter on a BEV or PHEV decreases (steps-down) voltage from the high voltage battery, e.g., 400-800 V, to low voltages as needed by the vehicle’s auxiliary systems. An onboard charger (OBC) takes AC power from the electrical grid and converts it to DC for storage on the vehicle’s battery.

CMU study finds that HEVs and PHEVs with small battery packs offer more emissions and oil displacement benefits per dollar spent than large pack PHEVs and BEVs; policy implications

Green Car Congress

Strategies to promote adoption of hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) with small battery packs offer more social benefits (i.e., We find that, in the base case, plug-in vehicles (PHEVs and BEVs) may produce more damage on average than today’s HEVs. Michalek et al. are also substantial.
