EV Charging at Home - should it be banned?
- Mar 31, 2022 10:41 am GMT
When one looks at the number of vehicles in the EU and the US there are too many for the distribution grid to support in many areas.
In many cases the distribution circuits will be 200-400 percent loaded based on current charging behavior.
1) Socialize the cost of charging at home, even though that is social unjust right now?
2) Require an off-grid DC solar PV system, and battery and only allow charging from that system?
3) Allow the distribution grid to overload and burn out?
4) Raise rates for EV charging to cover the cost of the upgrades directly without subsidy from any other use?
5) Regulate charging times and amounts via direct load control?
6) Ban all EV charging at home?
Unfortunately we need to pick a couple of these options. If we do nothing that we have picked option 3.
How do we deal with this load growth, understanding that much of the distribution infrastructure is at or beyond the design capacity already based on 24,000 real distribution circuits worth of data.
