That’s expensive, especially on top of a new EV purchase and charger install. How do you avoid a tragedy of the commons without mandating batteries on every new charger installation?
- Retric 5y agoAn EV driving 15k miles per year only averages ~500w of electricity 24/7. The infrastructure is therefore relatively cheap. So at scale a 1GWh battery pack can charge ~100,000 cars at any time of the day. But, assuming PV adoption continues electricity prices will be lower in the day so most people will end up charging at the office.
- letitbeirie 5y agoTwo things: > averages They average 500W but that's a lot of 0W mixed in with a little bit of 10,000W. If everyone decides they want their 10,000W at the same time it's not going to work out. > a 1 GWh battery pack Some day soon. For now though that's about the total installed capacity for the entire USA [0]. [0] https://www.eia.gov/todayinenergy/detail.php?id=40072 https://www.eia.gov/todayinenergy/detail.php?id=40072
