to be a problem. The power grid has dealt with people building more houses, and putting in electric powered devices - most recently air conditioners - for it's whole existence. They will be able to cope.
t a useful rate takes as much CONTINUOUS power as the heat coils in my furn ace which only runs sporadically on the coldest winter nights. That's the p oint. One night the four homes on a common transformer may not charge at al l. Another night they may all four be charging eight cars. This may not hap pen often, but the system has to be able to supply those extra kW compared to the loads they used to supply. In some neighborhoods this will require u pgrades of the local distribution. Otherwise no other part of the grid will be remotely stressed.
the supply would be able to the worst case. But provided that the cars are charged by some reasonable time in the morning they don't need to all charg e at the full rate.
can be done in a perfect future, but it is a long road with many hurdles t o get something agreed on that is effective and takes into account all part y's interest. This is exactly what I would propose rather than have the el ectric companies go to the oversight boards and impose a universal fee for expanding the local distribution and I have talked about this here. I just don't think it will happen without lots of vocal users. The power compani es have a vested interest in adding all manner of capital if it can be done at other's expense.
nuclear generators in Virginia and got the legislature to allow them to bil l the consumers for the half billion it cost. They may or may not ever bui ld the plants. So why did "we" get the bill?
st effective when at operating temperature. EV owners charge their cars so they finish and are still warm when they are ready to leave on cold mornin gs. This is at odds with minimizing overlap of charging and heating.
ome agreement on protocols can be centrally controlled.
customer to use the capability and have very little inconvenience.
ses is not so much of my total bill. There's also the fact that the billin g is set for the generating peaks which is not the same as the residential distribution peaks.
and do more in other countries. Our local company PG&E just adds a small c ontroller into the heating controller in return for a lower rate.
nd off independently so are already scattered across time. The only thing they can do that would be effective is to cut back on your overall heating energy usage during the cold spells which means your home is not warm. The y tried that in Maryland and then gave it up. I'm sure the consumers paid the bill for that too, just not up front. They have a special "fee" in Mar yland for those sorts of programs. I got freebies a couple of times from t hem.
s not so simple as putting boards in the cars. There are numerous safety i ssues involved in addition to various regulatory issues. Try connecting a solar generation capability that isn't 100% hard wired. It won't be appnot roved for you to throw the switch. not
ace they will never consider burning them up with this sort of plan.
One idea _I have not seen discussed is putting some solar cells on the car roofs. That could either extend the range of the car or reduce the amount of batteries needed.
