Study Finds PHEV Li-ion Cells Show Little Capacity Fade Under Combined Driving and V2G Usage; Economic Model Suggests Incentives Will Be Required for Vehicle Owners to Participate in V2G

Green Car Congress

Rather, it is the integrated number of lithium ions that have been intercalated/de-intercalated into the electrodes, regardless of the DoD at which these events occur. It appears unlikely that these profits alone will provide sufficient incentive to the vehicle owner to use the battery pack for electricity storage and later off-vehicle use.

BMW launches BMW i ChargeForward pilot in SF Bay Area

Green Car Congress

Working with a group of nearly 100 BMW i3 drivers, selected from approximately 400 applicants, BMW i ChargeForward will demonstrate how intelligent management of electric vehicle charging can contribute to optimizing electric power grid efficiency while reducing total cost of electric vehicle ownership. Second-life.

However, in a companion paper assessing the economics of V2G for consumers, they also concluded that the maximum annual profit for a PHEV owner to engage in V2G (~$10-$120) would likely prove insufficient to encourage use of the battery pack for grid electricity storage and later off-vehicle use.

MIT researchers conclude fundamental changes in the US energy-innovation system are needed to meet challenges of climate change and energy supply

Green Car Congress

A three-year study by a team of researchers based at MIT has concluded that fundamental changes are needed in the US energy-innovation system. The study was carried out at the MIT Industrial Performance Center and involved faculty and students from nine MIT departments.

BMW i ChargeForward Program to demo contribution of intelligent EV charging to grid efficiency

Green Car Congress

At the Consumer Electronics Show in Las Vegas, BMW announced the BMW i ChargeForward Program—a pilot study to be undertaken by the BMW Group Technology Office, together with Pacific Gas & Electric Company (PG&E). Grid efficiency through managed charging, combined with a used EV battery “second-life” system.

Classification of potential electrical storage for stationary applications. In their study, Yang et al. High discharge rates or high current densities are important, although the state-of-charge (SOC) of the storage system typically will not move over a wide range. Credit: ACS, Yang et al.

How clean is EV battery manufacturing?

Electric Auto Association

This 2017 study has been used by anti-EV commentators to discredit the climate performance of EVs. When EV batteries degrade enough to be unsuitable for cars (about 70% capacity remaining), they are re-used for electricity storage.
