Electrical distribution
Transitioning to EVs means reducing the supply-chain flow of conventional fuels and increasing the utilization of the existing electricity infrastructure.
Level 1 charging is not likely a problem for most electrical distribution systems as it is similar to adding a baseboard heater to a standard electrical outlet.
Level 2 charging pushes a typical 100 amp 120/240 residential electrical service to the limit and would require management with other high power demand devices such as stoves and clothes dryers. A single EV is the best a 100 amp residence could support.
The loading created by every distribution customers’ use of a level 2 charger on a daily basis would likely create a substantial load on the distribution system and prematurely age the transformers. It may require upgrading of the distribution transformer capacity. The Local Distribution Companies would need to review their standards for suitability.
Level 3 charging is likely to trigger infrastructure upgrades. Part of the cost would lie with the customer (meter side) and part would be the responsibility of the distribution company.
Cost impact can be minimized by managing charger energy consumption in a way that avoids overloads and triggering capacity upgrades.
Roadways
When you think about electric vehicles it is unlikely you would imagine that their increased use would impact our roadways – but they will…
Gasoline taxes are used to help fund roadways. As we reduce our fuel consumption, there will be less revenue available to maintain our roads.
We should expect some new form of taxation on EVs when their use begins to impact tax revenues.
For now… enjoy the ride!
