Mitsubishi Motors, NewMotion, Nuvve in vehicle-to-grid pilot in Netherlands with Outlander PHEV

Mitsubishi Motors Corporation (MMC) has launched a Vehicle-to-Grid (V2G) pilot, with the first charge point already being utilized with Mitsubishi Outlander PHEV’s in-vehicle storage batteries. Using V2G-technology, peak demand on the electricity grid can be better balanced, by allowing electric vehicles to not just take power from the grid, but also return it to the network and expect to introduce a new potential earnings model for electric drivers.

MMC is partnering forces with NewMotion, one of Europe’s largest providers of smart charging solutions for electric driving; grid operator TenneT in Netherlands; and Nuvve, a leader in V2G technology and grid service deployments. (University of Delaware Professor Willett Kempton, the pioneer of the grid-integrated vehicle concept, is Nuvve’s CTO.)

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

October 10, 2017

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. As reported in a paper in Nature Energy, the Stanford team achieved four-sodium storage in a Na2C6O6 electrode with a reversible capacity of 484 mAh g−1, an energy density of 726 Wh kg−1cathode, an energy efficiency above 87% and a good cycle retention.

Chemical engineer Zhenan Bao and her faculty collaborators, materials scientists Yi Cui and William Chueh, aren’t the first researchers to design a sodium-ion battery; however, they believe their approach has the price and performance characteristics to create a sodium-ion battery costing less than 80$% of a lithium ion battery with the same storage capacity.

OpenLV project proposes opening up local electricity usage data to improve EV charging

A new initiative in the UK is proposing opening up data from local electricity substations to provide network operators with much-needed information about levels of capacity for charging EVs on local electricity networks.

Currently, asserts the OpenLV project, electricity network operators don’t have enough information about how much spare capacity there is on local electricity networks. This makes it difficult to know whether a cluster of EVs charging at peak times will push the demand over the limit. The OpenLV project will, for the first time, open up data from local substations, so that Distribution Network Operators (DNOs), as well as third parties such as businesses and academia, will have more information about whether networks can cope with rising EV numbers.

Hyundai Mobis develops on-board bi-directional charger for V2G applications

August 16, 2017

Hyundai Mobis has developed an on-board, bi-directional charger for plug-in vehicles. The bi-directional onboard charger (OBC) allows the vehicle to supply electricity in its battery to the grid.

The power supplied by the vehicle can also be used as emergency power in homes. If more than enough power is supplied, it is possible to prevent a large power outage. In Korea, the amount of industrial damage caused by power outages is estimated to be 650 billion won (US$570 million) per year.

Groupe PSA and partners launch GridMotion; reducing electric vehicle usage cost with smart charging

May 12, 2017

Groupe PSA, Direct Energie, Enel, Nuvve, Proxiserve and the Technical University of Denmark have launched the GridMotion project with the aim of evaluating possible savings achieved by real-life electric vehicle (EV) users through the implementation of smart charging and discharging strategies for EVs.

An electric vehicle driver’s electricity bill could be reduced, with no impact on transportation use, by shifting charging times from periods when electricity prices are higher to periods when electricity prices are lower. Even further savings could be achieved by providing grid balancing services through a Vehicle to Grid (V2G) system. The 2-year GridMotion demo project will evaluate the savings EV users could achieve under real-life conditions with the implementation of smart charging and discharging.
