IBM, Honda and Pacific Gas and Electric Company Team Up For A Smart Grid
The idea of smart grid and intelligent two-way communication between electric cars and the power grid is not new. Tom Gage at AC Propulsion, the company that sowed the seeds for what was to eventually become the Tesla Roadster, has had a working version of what the company calls V2G, Vehicle to Grid. What the company’s V2G does is offer a technology that makes clean and efficient electric-powered transportation possible by allowing electric vehicles to power and be powered by the grid. AC Propulsion's electric vehicles have the energy source capable of producing the 50 Hz or 60 Hz AC electricity that powers our homes and offices using their tzero™ drive system.
IBM, Honda & PG&E. The pilot project will help demonstrate and test how an EV’s ability to receive, send information and respond to charge instructions based on the grid current condition can be done in the most efficient way. According to the vehicle’s battery state, the EV will be able to communicate with the utility it is related to and calculate when to charge, how much and for how long. Utilities stand the gain the most from it. With a serious need to understand and catch an insight as to the charging patterns form the coming EV energy use, energy providers need to develop ways to effectively manage charging during peak hours and ideally, offer incentive for consumer programs that encourage electric vehicle adoption.
With an expected 2.9 million worldwide EVs by 2017, EV and plug-in vehicles, PHEV will challenge the state of our current power grid. Indeed, the power grid is the weakest point in the EV experience chain and hasn’t been actively upgraded to handled intelligent two-way communication. Think of it at telephone switching central office before the Internet. Once the internet was active, the communication network became a smart multi-way media. The same needs to happen for utilities. By adding another much needed layer of energy transportation agility to the EV charging process, this will help make the charging experience seamless for consumers no matter where they are. It also doubles as an important incentive, that of ensuring our electricity source and transportations system is reliable and that its infrastructure is stable and secure.
