Daimler & enercity storing new replacement EV batteries in working 15 MWh grid storage system; “living storage”
February 02, 2016
Daimler AG, with its wholly owned subsidiary ACCUMOTIVE, and enercity (Stadtwerke Hannover AG) will begin construction of a new stationary energy storage system (ESS) this year; the facility also functions as a spare parts storage facility for electromotive battery systems.
Around 3,000 new battery packs, destined for the current smart electric drive vehicle fleet, are being pooled to create the ESS at the enercity site in Herrenhausen. With a storage capacity totalling 15 MWh, the installation is one of the largest in Europe. After completion, the energy storage facility will be marketed on the German primary balancing energy market. The storage facility is already the third major project for Daimler AG in this business sector.
Nissan and ENEL announce V2G system, launch smart grid trials in Europe
December 08, 2015
At the 21st UN Conference on Climate Change (COP21) in Paris this week, Nissan announced the development of a Vehicle-to-Grid (V2G) system which will allow drivers to operate as individual energy hubs with the ability to store, use or return electricity to the grid.
Nissan will commence Smart Grid trials in partnership with multinational energy manufacturer and distributor, ENEL. In March, Nissan and Endesa, an Enel Group subsidiary, had signed an agreement at the Geneva International Motor Show pledging to work together to deliver a mass-market V2G system and an innovative business model designed to leverage this technology.

Daimler and partners deploying world’s largest 2nd-life EV battery storage unit for grid support
November 04, 2015
The world’s largest 2nd-life battery storage unit will soon go into operation in the Westphalian town of Lünen. A joint venture between Daimler AG, The Mobility House AG and GETEC, it will be operated from the beginning of next year at the site of REMONDIS SE and marketed in the German electricity balancing sector. The stationary storage unit, with a total capacity of 13 MWh, uses second-life battery systems from the second generation of smart electric drive vehicles.
Under the banner of “E-Mobility thought to the end,” Daimler, The Mobility House, GETEC and REMONDIS are mapping out the entire battery value creation and recycling chain with their project in Lünen. The process demonstrably improves the overall environmental performance of electric vehicles, thereby helping to make e-mobility more economically efficient.
New EU/US lab for interoperability of e-vehicles and smart grids
October 29, 2015
Following the Transatlantic Economic Council’s decision to promote electric vehicles and smart grid interoperability, on 29 October the European Commission inaugurated the European Interoperability Centre, a laboratory operated by the JRC.
Together with its partner facility in the US Department of Energy’s Argonne National Laboratory, the new lab will ensure that the next generation of electric cars and smart grids are fully interoperable, based on harmonized standards, technology validation and testing methods. This is an important step towards creating “a single language” for all components.
Oak Ridge AMIE demo integrates 3D-printed building, natural gas hybrid with bi-directional wireless power transfer
September 24, 2015
A research demonstration unveiled at the Department of Energy’s Oak Ridge National Laboratory (DOE ORNL) combines clean energy technologies into a 3D-printed building and a 3D-printed natural gas-powered hybrid vehicle to showcase a new approach to energy use, storage and consumption. The Additive Manufacturing Integrated Energy (AMIE) demonstration, displayed at DOE’s Office of Energy Efficiency and Renewable Energy Industry Day event, is a model for energy-efficient systems that link buildings, vehicles and the grid.
An ORNL team worked with industrial partners to manufacture and connect a natural-gas-powered hybrid electric vehicle with a solar-powered building to create an integrated energy system. Power can flow in either direction between the vehicle and building through a lab-developed wireless technology. The approach allows the car to provide supplemental power to the 210-square-foot building when the sun is not shining.
BMW launches BMW i ChargeForward pilot in SF Bay Area
August 04, 2015
The BMW Group Technology Office, together with Pacific Gas and Electric Company (PG&E), have launched an 18-month pilot of the BMW i ChargeForward Program in the San Francisco Bay Area. The program is now issuing calls to participating BMW i3 drivers in the Bay Area to request the interruption of the charging of their EVs for one hour.
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. The study has two parts: (1) a managed charge pilot program involving BMW i3 owners; and (2) a battery second-life energy storage system.
Audi e-gas plant qualified to participate in balancing market to stabilize grid
July 15, 2015
The Audi e-gas plant in the city of Werlte in Lower Saxony (earlier post) produces CO2 neutral-fuel (synthetic methane from water, renewable electricity and CO2); it now also contributes toward stabilizing the public power grid. After successfully completing a test sequence, the plant is now qualified for participating in the electricity balancing market.
In the German electrical energy mix, the share of renewable energies is growing rapidly, reaching 33% in the first half of 2015. However, regional expansion of wind and photovoltaic generation plants leads to increasingly larger load fluctuations. It is therefore important to have flexibly available consumers such as the Audi e-gas plant to buffer load peaks and thereby stabilize energy grids.
CA Energy Commission awards CSE $1.5M for development of standards-based smart EV charging platform; first employment of ISO/IEC 15118
June 12, 2015
The California Energy Commission has awarded a $1.5 million grant to the Center for Sustainable Energy (CSE) to lead development of an advanced management platform for integrating electric vehicle (EV) charging with utility-scale energy systems. CSE will work closely with KnGrid, a leader in vehicle-grid communications, to create a standardized platform that optimizes charging benefits for both grid operators and vehicle owners. The result will be the first data platform to employ the international ISO/IEC 15118 standard for flexibly managing vehicle charging with data from the power grid.
The project team will develop and implement the first standards-based smart charging platform, termed a “demand clearing house” (DCH) in the international ISO/IEC 15118 protocol (entitled “Road vehicles - Vehicle to grid communication interface”), that will consolidate real-time grid profiles from local utilities and energy market pricing from the California Independent System Operator (CAISO) with simultaneous charging of grid-connected EVs.
Daimler enters stationary energy storage market with ACCUmotive battery systems; 500 kWh unit already on line for grid stabilization
May 29, 2015
Daimler is entering the commercial and residential stationary energy storage system (ESS) market with its wholly-owned subsidiary Deutsche ACCUmotive. The announcement comes four weeks after Tesla Motors announced its own entry into the ESS market with the home PowerWall Li-ion battery system (earlier post), although Daimler has been considering the move for several years.
Daimler’s first industrial-scale lithium-ion unit is already on the grid and is being operated by the partner companies The Mobility House AG and GETEC Energie AG. The 96-module ESS currently has a total capacity of more than 500 kWh; it will be increased step-by-step to 3000 kWh by the partners in the coming weeks. Daimler AG is planning to collaborate with EnBW AG for distribution to customers in Germany. Daimler is also aiming to enter into cooperation with other sales and distribution partners both in Germany and at international level.
LG Chem and Eguana partner on Li-ion residential energy storage system for North America
April 23, 2015
Eguana Technologies, a supplier of power control and conversion solutions for distributed energy storage systems and Li-ion manufacturer LG Chem have combined their technologies under a multi-year agreement to deliver a certified, fully integrated energy storage system (ESS) Eguana calls “AC Battery”. The modular system is targeted as a residential product, but also has the potential to be aggregated for small commercial and industrial (C&I) end-users.
Basic product capacity is 6.4 kWh. Eguana designed the package around LG Chem’s battery modules and supplies its Bi-Direx inverter and controls subassembly. The low voltage design enables high-capacity batteries to operate in lower power ratings needed for decentralized systems (i.e. residential rooftop solar). Eguana has also worked with Germany-based Sonnenbatterie on a similar ESS solution.
CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix
April 16, 2015
In a study focused on the PJM portion of the US electricity grid, researchers at Carnegie Mellon University (CMU) found that although charging electric vehicles at night (when electricity is cheap and wind power is typically more plentiful) could lower electricity costs, doing so also creates more air emissions, and that the health and environmental costs from these emissions outweigh the electricity cost savings. A paper describing the work is published in the ACS journal Environmental Science & Technology.
Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. The result of the analysis depends on the details of the region, notes CMU Professor Jeremy Michalek, corresponding author—i.e., other parts of the US and the world could be different. The question of electricity costs vs. health and environmental cost is important to ask everywhere, Michalek said.
SDG&E piloting integration of EVs and energy storage systems into CAISO energy markets for demand response services
February 24, 2015
In a pilot vehicle-to-grid project, San Diego Gas & Electric (SDG&E) is actively bidding a group of energy storage systems and electric vehicle fleets as one resource directly into the California Independent System Operator’s (CAISO) energy markets. These markets include those that address short-term imbalances in electricity supply caused by such things as intermittent renewable energy. This marks SDG&E as one of the first utilities to integrate EVs into California’s wholesale energy market.
The project currently aggregates stationary storage systems together with the charging demand of EV fleets at five separate locations throughout San Diego County. The assets are remotely controlled using software that both balances the participant’s charging needs, and identifies opportunities to provide demand response services at the grid level.
