It's too bad you couldn't just hitch a secondary external battery pack to a mini-trailer hitched to the car for long distances. Roll into a station, unhitch the pack, swap for charged one, go on your way maybe 15 min later.
I know there are proposals for swappable internal packs, with automatic swap machinery at the station, but a trailer hitch and external plug requires a lower capital investment, and is much less intrusive to the vehicle design.
- pmjordan 13y agoI thought the whole problem with "just add more batteries" is that you drive up mass and thus reduce power efficiency, thus leading to a cycle of diminishing returns? I don't know how far along that curve a Tesla Model S is though.
