New study finds V2G discharging harmful to EV batteries

Vehicle-to-grid (V2G) technology is seen as a potentially valuable resource for balancing electrical grids and facilitating the use of renewable energy. However, a new study by a team at the University of Hawaii suggests that the additional cycling to discharge vehicle batteries to the grid is detrimental to battery performance. In “Durability and reliability of… Read more »

Danish Parker project developing V2G standards

A Danish-led consortium aims to advance the technology of EV grid integration. Partners in the Parker project include automakers Nissan, Mitsubishi and PSA, as well as the Technical University of Denmark and several electric utilities. EVs can theoretically help to stabilize the electrical grid by charging their batteries when there is surplus power, and returning… Read more »

Study: Consumers want optimized charging, renewables, V2G

A national survey of consumer attitudes towards plug-in vehicles suggests that people would prefer control to convenience in many charging scenarios, and that most want to be able to choose renewable energy. For “Consumer Preferences for the Charging of Plug-In Electric Vehicles,” researchers Brandon Schoettle and Michael Sivak of the University of Michigan Transportation Research… Read more »

Is V2T (vehicle-to-train) the next energy storage technology?

The EV of the future will be just one component of an integrated transportation/energy ecosystem that includes private cars, public transport, renewable energy sources and stationary storage. Could trains and cars, both powered by electricity, share not only passengers, but also energy? The idea may not be as outlandish as it seems. Hybrid and electric… Read more »

EVgo partners with UC San Diego on vehicle-to-grid projects

Charging network operator NRG EVgo is leading two pilot projects at the University of California San Diego to study the potential of vehicle-to-grid (V2G) technology. In the first project, EVgo has built a site to assess how owners of DC fast charging sites can use solar generation, battery storage and control systems to mitigate expensive… Read more »

Center for Sustainable Energy to develop platform for integrating EV charging with the grid

The California Energy Commission has awarded a $1.5-million grant to the Center for Sustainable Energy (CSE) to develop a platform for integrating EV charging with utility-scale energy systems. CSE will work with charging network operator KnGrid to create a standardized data platform using the ISO/IEC 15118 standard. “By leveraging an international standard for how EVs… Read more »

Nissan and Endesa partner to develop mass-market V2G system.

Nissan and Endesa have agreed to work together to develop a mass-market vehicle-to-grid (V2G) system. The two companies plan to introduce V2G services in the European market and to explore the use of second-life EV batteries for stationary applications. “Every Nissan electric vehicle battery contains a power storage capability that will prove useful in contributing… Read more »

San Diego utility integrates EVs into California’s wholesale energy market.

San Diego Gas & Electric (SDG&E) has launched a pilot vehicle-to-grid project under which it will bid a group of energy storage systems and EV fleets as one resource directly into the California Independent System Operator’s (CAISO) energy markets. Utilities use storage resources like this to address short-term imbalances in electricity supply caused by such… Read more »

PG&E and BMW team up to test V2G services

Pacific Gas and Electric Company (PG&E) and BMW are working together to test the ability of EV batteries to provide services to the electrical grid. PG&E selected BMW after a competitive solicitation to manage a minimum of 100 kilowatts of electric demand on PG&E’s system, as other large industrial and commercial customers do today as… Read more »

Automakers and utilities develop cloud-based platform for vehicles to communicate with power grids

Eight of the top global automakers are collaborating with the Electric Power Research Institute, 15 utility companies and Sumitomo Electric to develop a two-way communication platform that would allow plug-in vehicles from all participating manufacturers to communicate with power grids via the cloud. The new technology, which was demonstrated this week, enables utilities to send… Read more »
