I am trying to find out which is cheaper for a long run, public charging points of petrol? I go online to find out and cannot. Anyone help?

It will depend on what you pay for electricity and petrol which varies across the country, and also changes with time.

I did the calculation a year ago when motorway electricity prices were an extraordinary 83 pence per kWh, which made the electric fuel cost equivalent to petrol. Given that I run an electric car solely for economic reasons I refuse to pay those prices and only charge at home with electricity costing 16 pence per kWh, a fifth of the motorway cost.

Thanks. 

As a newly to hybrid, do I need to carry the charging cable so I can charge the vehicle at a motorway station? Or are the connections the same for all makes of vehicles?

 

 

If your car has a CCS connector you can charge almost anywhere, because CCS has become the dominant charge point connection, invariably with a tethered cable. Type 2 is nearly extinct, while Chaedemo is not far behind.

I dunno what type my connector is. See pic.

That is a type 2. You will be lucky to find a working type 2 charge point in my part of the world, and if you do you will often need your own cable.

Having said that, a picture of the charging port of your car would be more helpful because it may be a CCS (combined charging system) having the 7 pin AC connection you showed plus beneath it a separate 2 pin connection for DC. The point being that CCS allows AC charging at home and DC charging in public. 

My mistake. The pic of the cable is for charging using a 3 pin home socket.

2 pics, one of the car charging port of on car and one of charging cable for industrial power outlets.

The car port is type 2 only. Good luck finding a working public charge point, and definitely take your own cable.
