PNNL study finds 2028 grid resource adequacy likely sufficient for high EV penetration; managed charging strategies can double adequacy

Green Car Congress

A new study of the impact of high EV adoption on the Western US power grid by a team from Pacific Northwest National Laboratory (PNNL) has found that 2028 grid resource adequacy—from generation through transmission—is likely to be sufficient for high EV penetration. Storage is used in California to meet the peaks set by EVs.

UCR researchers find commercial fast-charging damages EV batteries, propose new internal-resistance-based technique

Green Car Congress

Commercial fast-charging stations subject electric car batteries to high temperatures and high resistance that can cause them to crack, leak, and lose their storage capacity, according to researchers at the University of California, Riverside (UCR) in a new open-access study published in the journal Energy Storage.

UC Irvine study concludes intelligent PEV charging can minimize scale of stationary energy storage needed to meet renewable targets

Green Car Congress

A new study by a team at the University of California Irvine highlights the importance of intelligent plug-in vehicle (PEV) charging for minimizing the scale of infrastructure required to meet renewable utilization targets. However, with smart charging of PEVs, required power capacity drops to 16% and required energy capacity drops to 0.6%.
