IBM, Honda, and PG&E partner on smarter charging for EVs; utilities to communicate charging instructions directly based on grid conditions
12 April 2012
IBM has teamed with American Honda Motor Co., Inc. and Pacific Gas and Electric Company (PG&E) on a new pilot project that will allow communication between electric vehicles (EVs) and the power grid. This project will demonstrate and test an electric vehicle’s ability to receive and respond to charge instructions based on the grid condition and the vehicle’s battery state.
This demonstration combines grid and vehicle data to create an individualized charging plan for Honda’s Fit EV battery electric vehicles (BEV), using IBM’s cloud based software platform. By utilizing the existing in-vehicle communications system in the Honda Fit EV, the electric vehicle can interact with utilities and the grid, creating a direct channel for sending and receiving usage information that could improve local grid management.
Once plugged into a charge post, the Honda Fit EV initiates a charge request via the vehicles telematics system. This request is sent to IBM’s Electric Vehicle Enablement Platform where vehicle data such as battery state and grid data received from PG&E, is combined to create an optimized charge schedule, which is then communicated back to the vehicle in seconds. Using this aggregated data, the vehicle has the intelligence to charge to the level that is needed while factoring any current grid constraints.
Using real time and simulated data, the system will test and demonstrate the ability to alter, as well as adapt charging patterns based on grid conditions. This smart charging capability will enable energy providers to manage the power used by EVs during peak times by instructing vehicles to delay or adjust charging if required.
Additionally, the IBM EV platform can collate historical EV charging data and create a profile that can be used to forecast the location and duration of EV charge loads. For example, the program can determine how many EVs are plugged in one neighborhood and the time it will take for each to reach a full charge. This level of insight will allow utilities to optimize grid operations and help reduce the chance of outages.
By communicating information directly to the vehicle, this project has the potential to significantly improve driver services. For example, the IBM’s cloud based platform could provide charge post location information and availability directly to the EV, using the telematics and Satellite-Linked Navigation to guide the driver to the most convenient place to charge.
This project along with the recently announced EKZ Smartphone Application (app) pilot will help engage consumers and encourage more drivers to “plug in.” The smartphone app shows the vehicles battery level, range of travel distance, vehicle location, and current energy costs in real time. This technology coupled with the ability to communicate directly with charging stations via a GPS system, will offer consumers a “connected” driving experience.
In addition to the two pilot projects, IBM is currently a member of the EcoGrid EU consortium, a group focused on developing an energy grid that uses at least 50% of renewable energy sources, such as wind power, solar energy and biogas.
