It's one thing to install a charger in a two-car garage. Installing charging capacity for 20, or 50, or 100 cars is something else. I'm not sure how most existing apartment buildings could handle all of their tenants charging their cars at night at the same time. I'm not even clear on how much strain that would put on the electrical grid.
How much more power would we need to produce to handle the demand if everyone had electric cars instead of gas cars? That power consumption would be added on top of all the power consumption we currently have.
- theshrike79 6y agoWe already do this in Finland. Pretty much every single private parking spot in an apartment building will have a 8A plug for block heaters and cabin heaters (1,5-2,5kW load). They all trigger around 6 in the morning so the car is nice and warm for the 7:30 commute. Nothing melts, nothing breaks or starts smoking. And even then people are panicking about EVs charging from 2100-0600 overnight. NOW they think everything will melt, break and be on fire.
- castratikron 6y agoSeems like this could be solved if the chargers were networked and programmed with a set group charge limit. If you are a charger, and you're the only charger actively charging, you get 100% of the limit; two chargers get 50% of the limit; three chargers get 33% of the limit, etc.
