BMW begins Phase 2 of ChargeForward Program with PG&E to study advanced electric vehicle charging; results from Phase 1
14 November 2016
In an effort to further understand and expand the possibilities of smart charging for electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs), BMW of North America announced a second phase of its BMW ChargeForward program. BMW i3, BMW i8 and iPerformance owners in the Greater San Francisco Bay Area who are Pacific Gas and Electric Company (PG&E) customers are invited to apply for participation in a 24-month program focused on managed EV and PHEV charging. Funding for this second phase was secured through a competitive bid for a California Energy Commission (CEC) grant.
Phase 1 of the program demonstrated the viability of creating grid value by optimizing smart charging of EVs. (Earlier post.) BMW developed innovative solutions that utilize the existing vehicle communication system both to create value for customers and to help optimize the electric grid through demand response, which improves grid reliability, lowers costs and helps the environment by incentivizing customers to reduce usage during periods of high peak demand.
BMW was the first to showcase this technology in a real-world application. Conducted with PG&E from July 2015 through December 2016, BMW enabled nearly 100 BMW i3 owners located in the San Francisco Bay Area to earn an incentive by offering flexibility in the time by which their vehicle was charged.
Building on the functionality tested in the first phase of the BMW ChargeForward initiative, the new phase will explore the ability to optimize charging events, whether the vehicle is charging at home or on the go.
The goal is to expand and to test new smart charging functionality to generate greater benefits to the grid (including optimizing across multiple charging events, shifting charging across grid locations, adjusting charging according to the level of renewables on the grid, and exploring the benefits of optimizing charging in response to a variety of grid signals) and to EV and PHEV drivers (by way of participation incentives).
As in the first phase of the pilot, BMW will ensure participant-drivers’ expressed mobility needs are always met, while using remaining flexibility to create grid value.
Phase One Findings. During the first phase of ChargeForward, PG&E sent signals to BMW requesting a load reduction on the grid of up to 100 kilowatts (kW). In response to these demand response signals, BMW selected vehicles for delayed charging (up to one hour delay per day), based on drivers’ communicated mobility needs.
Driver-participants could also choose to opt-out of participation as desired if they needed to begin charging their BMW i3 immediately. BMW supplemented the smart charging of these vehicles with a solar-powered battery system made from BMW Group second-life EV batteries to support the grid during these demand response events, as necessary. Results from the first phase of the pilot with the BMW i3 include:
Nearly 100 BMW PG&E customers in the Greater San Francisco Bay Area who own BMW i3 EVs participated in the pilot.
Satisfaction has been high with 92% of participants indicating they are very satisfied with the pilot and 86% indicating they would likely recommend it to family or friends.
A total of 192 demand response events took place between July 2015 and October 2016, with events scheduled through the end of 2016.
In 94% of the demand response events through October 2016, BMW successfully reached the full grid load reduction of 100 kW requested by PG&E.
By August 2016, more than 19,000 kilowatt-hours (kWh) were shifted as a result of ChargeForward events, avoiding costly and carbon-intensive electricity generation.
BMW ChargeForward pilot goals. Participants can earn up to $900 for participating in this 24-month pilot, with all participants receiving a $300 initial incentive soon after program launch. The total amount earned over the two years depends upon individual participation in charging events. Customers may also have the opportunity to earn additional incentives for participating in short-term charging tests, or sub-pilot projects, that may occur during the 24-month period.
Through BMW ConnectedDrive, which enables connectivity between cars, drivers and their surroundings, and a special BMW ChargeForward smartphone app, participating BMW drivers will be able to opt-out of any smart charging request, based on their driving preferences. If a customer does not opt-out, the vehicle charging can be shifted to meet the needs of the energy grid.
BMW seeks more than 250 BMW i3, BMW i8 and iPerformance drivers located in the Greater San Francisco Bay Area to participate in this pilot by completing an application at www.BMWChargeForward.com, starting today, November 14, 2016. Throughout the 24-month pilot, BMW will manage the at-home and on-the-go charging of selected BMW i3, BMW i8 and iPerformance vehicles, to optimize grid reliability and support renewable energy integration.
The first phase pilot employed BMW Group second-life vehicle batteries from the MINI E Field Trial to support on-the-road customer BMW i3 vehicles in order to advance the benefits of sustainable electric mobility. The second phase of BMW ChargeForward will incorporate a stationary home battery storage system for a limited number of homes, as part of its exploration of smart vehicle charging in the context of homes with diverse energy resources. As in the current pilot, these storage systems will include BMW second-life batteries, demonstrating BMW’s commitment to sustainability throughout the product lifecycle.
It seems obvious to me.
You need X kw by time Y.
Yow want to charge when electricity is cheap and avoid charging when it is expensive. This will vary on the sources of renewables (wind or solar) and whether max demand is based on air conditioning or cooking / heating.
Ideally, you could get people to charge when there is a lot of solar or wind and avoid it when demand is high. All this can be predicted out 24 or 48 hours.
Then it depends on the battery size. If you have a "1 day" battery, you can only look forward 1 day (like a Nissan Leaf), but if you have a larger battery, you could further optmise it by looking out to a second day. [ This would be particularly useful when the electricity comes from wind. ]
After that, all you can do is avoid charging at peak times.
You also need a way of rewarding people for "being good" and cooperating with the scheme (I suppose by giving them cheaper electricity.)
I wouldn't bother with V2G at this stage, just time charging.

sorry, X KwH by time Y.

More quick chargers, more renewable energy and V2G for all those cars sitting in parking lots.
