If copper thieves are stealing charging cables, the solution is dead simple...
Keep the cables on the car side, not the charger side. Provide an outlet on the charger, driver supplies their own cable.
This could work, but it would be extremely wasteful. Instead of one cable serving dozens of cars per day you'd have dozens of cables, one for each car, used only once that same day
Each driver carrying their own cable wouldn't have to worry about the quality of the cable on the charger.
Pretty sure Europe does this already.
If they were compatible with the charger they use at home, it wouldn't be nearly as wasteful as they'll need one there anyway
Nah, make the cable retractable, and only release it after a payment method has been approved. Also post security or put charging stations near police departments.
I can tell when someone hasn't used a DEF pump for diesel vehicles. The hose not retracting on DEF pumps happen pretty often. They also try to retract while pumping making filling DEF a 2 hands required operation.
I hope that whoever designed DEF pumps will step barefoot on a lego block daily.
It would need to be a better design than that! Even a hanging loop behind a door would be better than that.
The level 2 charge point chargers that are retractable I've seen twisted and turned into knots. Sometimes the retractor on those are broken and the car parked in the neighboring stall parked on top of the cable I wanted to use.
As EV adoption increases, the amount of asshole and indifferent behavior is also increasing. Any design with moving parts will need to take that into account
That would work for Level 2 charging, but Level 3 DC fast charging requires a recirculating liquid cooling jacket inside the cable close to the conductor to allow the high current fast charging.
I mean, it looks do-able, you just need something like this with a plug on both ends:
https://www.evchargesolutions.com/replacement-cable-and-connector-DC-fast-charger-p/rpe-ev150p-20.htm
"150 max amp @ 600 volt DC"
Those are the older style cables that aren't liquid cooled.
Cost would be a big issue too. You see that replacement cable is listed at $575 as is. It would be even more for the double ended version (and I'm not sure two connectors is allowed in the CCS 2 spec).
The car already has water cooling anyway. But the cable could also just be not hanging around freely.
Car cooling cools the car, not the cable. If you're removing the cooling requirement from the cable you either burn up the cable or downrate the charging session to be significantly slower.
Where are you proposing the cable go if not hanging/attached to the charger?
The cable is with the car in this proposed case, why should the existing cooling not be able to cool it?
I'm the other case, of course it is connected to the charger. Just not freely dangling around outside for everyone to grab it. The same way the hoses of a fuel station mostly stay in the pump. Now just add a little bit more protection to this existing system and boom done.
