I'm curious to hear how your comparison goes. In general a circuit diagram of a charging circuit is a couple of resistors, some capacitors and a few transistors to control the flow. But each of those pieces have some level of "loss". Typically, the more current, the more loss.
In my mind, the Tesla circuit is faster because it's going to jam more current into the circuit. This will definitely be faster, but it will consume a little more power.
So, if you can keep track of Cost, KWH and time taken, it'd be very interesting.
Does Tesla provide any information on what they do with their spent batteries? I've Googled a couple of times, but not found any info that satisfies. I was wondering if you, as an insider, know where the elephant graveyard is?
I'm trying to figure out if the discrepancy between the advertised per kWh price on these public chargers isn't being advertised correctly or if it's actually energy loss. I'm kind of leaning towards the former but won't know for sure until I can do a full charge.
Tesla has said that they'll recycle close to 100% of the materials from spent batteries to make new battery cells. I think they haven't had a chance to implement this yet because most of the battery packs they've made are still in use. I think are actively planning the recycling program now though to get ahead of the day when the packs are dead. I'd love to see a replaceable battery cartridge that could just quickly slide in and out.
If the electric car industry could standardize, swappable battery packs could replace gas at "Fueling Stations". Lots of changes would be required, but it is definitely possible..--- just like Propane tanks.
