Newly Built Californian Homes Should Be Electric Vehicle Ready

Adapting an old house to accommodate wiring that can handle the 240v/40 A needed to recharge an electric vehicle might discourage people from taking the big step. That’s why new homes should now be built taking this into consideration.

Palo Alto has already ruled that new houses will be pre-wired for EV charging and now it’s time for California to handle the same issue.

According to The Long Tail Pipe, the California building Code (CBC2016) appears to require electric vehicle charging infrastructure in newly erected parking lots and houses. The documents are not specifying charging station installations, but the conduit and electrical system calculations required to sustain such a device.

The change won’t be as costly as it sounds, for a regular house the extra funding needed for the extra wiring being set at about $50. Which is a lot less expensive than when you already have a house and you’ll need to drill new holes and trenches for bigger cables to run through.

The study also shows that California will need over 1 million charging stations by 2025 in single- and multi-family dwellings if the whole electric vehicle trend catches on. This means local transformers will need to be upgraded too, because the more powerful the charging circuits, the more quickly will local transformers run out of capacity.

Just imagine how much the electricity demand will raise in the evening, when most people return from work and will have to recharge their EVs for tomorrow, watch TV, use electric boilers and such.
