Why are all these electric or hybrid vehicles carrying charging cables around ?
Isn't that an inefficient use of the worlds resources ? All that copper and plastic.
Surely the cable should be part of the charging station.
My understanding is that the charging stations have their own cables. You might carry a cable with you in the car if you wanted to be able to plug in to a random 3-pin plug somewhere.
Scott.
Not so. Public 7.4 and 22kW chargers normally require you to plug in a cable, it is only the higher powered 50kW CSS, etc. chargers that have a built in cable.
For the lower powered chargers It undoubtedly dates back to when there were several plug types in use so you couldn’t charge if they attached a cable with a ‘type 2’ plug if your car required a ‘type 1’. The higher powered ones never had that problem, and there is also the issue of needing a very beefy cable if you are dumping 50kW or more into your car.
However although the mix of socket types is mostly academic these days as the EU required all new cars to have a ‘type 2’ socket, now those lower powered chargers are expected to be in the ‘untethered’ style rather than ‘tethered’ I doubt they will change.
So not only do most people have to carry around a cable to plug into a 7.4 / 22 kW charger, they might also carry a three pin ‘granny’ cable, although with the bigger batteries in BEVs some manufacturers of those cars no longer supply them with the car but if you want one you need to buy one. The logic being the bigger battery means there is less of a range issue, and if you wanted to charge a 50kWh or larger battery with a three pin plug it would take forever and might be dangerous delivering a constant 3kW through a normal plug for 24 hours or more.
