The EV Transition Explained: Can the Grid Cope?

Cars That Think

There have been vigorous debates pro and con in the United States and elsewhere over whether electric grids can support EVs at scale. Residents can access about 1,000 charging ports spread over 277 public charging stations , with another 3,500 or so charging ports located at residences. The answer is a nuanced “perhaps.”

Xcel Terms First Phase of Sodium-Sulfur Battery Wind Energy Storage Test Project Successful

Green Car Congress

Xcel Energy has released the preliminary results from its wind-to-battery (W2B) storage project in Minnesota, and termed the technology successful. In October 2008, Xcel began testing a one-megawatt sodium-sulfur (NaS) battery ( earlier post ) to demonstrate its ability to store wind energy and move it to the electricity grid when needed.

Profile: Li-ion Provider Compact Power, Inc. Focusing on the Automotive and Vehicle Markets

Green Car Congress

In Li-ion batteries, Li ions (Li + ) leave the cathode during charging and move through the electrolyte and separator to intercalate into the anode. As the technology gets fixed, the anode is more of an issue related to fast charge. Generic Li-ion cell and various component technologies. The reverse happens on discharge.

Comprehensive modeling study finds electric drive vehicle deployment has little observed effect on US system-wide emissions

Green Car Congress

There are three reasons for this lack of observed effect, they concluded: (1) at present the overall share of emissions from the LDV sector is only 20% of US CO 2 emissions; (2) EDV charging can still produce comparable emissions to conventional vehicles depending on the grid mix; and (3) the effect of other sectors on emissions is significant.
