The gist is that the current state of our grids won’t withstand an influx of electric vehicles, EV and plug-in hybrids, PHEV. The grids need to be modernized at great cost, which has been left aside for decades. Grids need to become smart, meaning they need to tolerate workload balance and figure out where and when energy is to be distributed. This means modernizing transportation lines and software written to handle the loads.
V2G To The Rescue. We’ve written a bit about V2G and it’s impressive technology. Car makers as AC Propulsion and it’s eBox sport it. What does it do? It is when an EV and PHEV connection is made to allow electricity to flow from cars to power lines. EVs and PHEVs can put out over 10kW, the average draw of 10 houses, according to the University Of Delaware.
Technically speaking, V2G is strongly endorsed by the head of the Federal Energy Regulatory Commission, FERC and works like this; your EV or PHEV is plugged in and communicates to the utility, which tells it when it can charge and at what rate. This can be pre-programed by the user so that the recharging will only happen at low peak, with cheaper electricity. The best part of V2G is that it can reverse the flow of electricity back into the grid. This is especially important as it gives utilities extra electricity and the consumer some cash back, or other form of payment. The last technological point to this great technology is that instantaneously, EVs and PHEVs act as mini rolling substations where energy is stored and used when needed by the grids.
It’s technologies as these that will help revamp our aging grid infrastructure and allow for the use of EVs and PHEVs.
