I'm not crazy, the attack has begun.
Sorry, I forgot people install imaginary charge points that cost £0!Look this is patent nonsense. We have a hypothetical cost of an OBC which D insists is thousands but is probably 100s.
There is a supposed huge cost to write software etc: this is a fixed cost whether OBC fitted or not so cost saving is NIL.
YOUR numbers are made up.
... Look, I am saying 'no effective cost change', what is YOUR argument for saying one is more expensive than the other?
The cost saving is NOT the box, I am suggesting those cost changes are flat neutral. The savings are;
- no AC outlet required
- no carting around dead weight that some people won't use (= CO2 saving too)
