The conventional charge point seems to cost many thousands per unit.
As you know, you only need an RCCD protected supply for it to be safe so why the crazy cost.
They are very nice with their swipe card systems etc. but no use for high volume roll out which EV's need until battery technology can achieve the range to match or hopefully exceed ICE's.
In my quest to get a large amount of charge points rolled out I have found several reasons behind commercial produced points and their costs, at the end of the day they are all valid.
You cant just stick a 13A or any power outlet on the highway without it going through a lot of approval channels, certification and testing before you can go anywhere near the highway with your charge point.
Next you need to make them muppet proof, while you an I understand RCD's and other such things many folk just dont understand them.
Also you need to meter the supply, while giving free electric is all well and good while numbers are low do you think folks are going to be too keen to give way upwards of £800 of electric a year (based on a 20kwh load per day for a year at a price of around 12p a unit ) if the charge point gets used a lot.
How do you stop any Tom Dick or Harry using the point to supply say their motorhome, hedge cutter, boil a kettle for a cuppa, or just plug a lead in and run it striaght into their house (its been done with streetlights
How do you go about making sure you charge the right people for the power/parking etc when they use the point, thus the requirement to have a fob based system with a secure access to the power.
Would you be happy to have anyone just plug in to your home and suck up that sort of power, could you afford it ?
You can'nt just bung power points up willy nilly in the street with no thought to how the end user can pay for the power or the safety of the user or other members of the public I'm afraid
Obviousely charge points that are on private ground need little of the above and the owners are very generous allowing us to plug in but I have to wonder long they will survive once the points start to get used considerabley and the owners find their electricity use start to increase beyond the levels of their orginal generosity
