First, in the US. Less than 0.5% of car trips are over 150 miles. 90% of light vehicle charging needs can be met with off peak charging each day. In the US 70% of households live in single family homes and charging at home is possible. L1 basically free, L2 $2000 or so.
Is fast charging important? Yes of course. Folks want 100% of the vehicle use cases covered.
How to install L2 at 30% of households living in apartments?
The cost is between $2599 to $10,000 per apartment. That is a long term investment so a 30 year loan covered by rent increase? Currently there is no real plan.
Using high speed charging for apartments could work. Place high speed ports 6 minutes from apartments and charge one week fuel need in 10 minutes, better 5 minutes. This is actually cheaper than L2 if 100% used. Apartments need to own their share, (coop?) so electric power rates are minimized.
Final point for apartments, L2. Charging costs can be lower with sw that charges based on need. Also limit charging to 50 miles max per day. If more is needed go to local high speed charger.
Grid batteries are getting cheaper so high speed charging grid infrastructure can be added making it cost effective to have high speed charging without expensive grid upgrades.
