Lots of players pulling in different directions, and on a global basis.
There is a private charging network......people plugging in at home but the "no off street parking" or "blocks of flats" problems need resolution.
a Public charging free for all....I hesitate to call it a network...although so far so good in Northumberland.
I am sure there is an expectation from the driving public that an electric vehicle charging network should retain some of the features of the petrol/diesel network they are familiar with including....
To be able to get and pay for on a PAYG basis, electricity from any supplier without having to join a club, or sign a contract.
To have a mandatory price/unit which is advertised boldly at the charging station so the driver has a choice whether to get their electricity from that station or go elsewhere.
To be able to recharge their vehicle at any and every public charging station throughout the UK with no regard for what kind of plug is fitted to their vehicle eg for an EV to satisfy construction and use regulations, and be sold in the UK, it must provide a means of recharging from the UK's charging network.
So all petrol and diesel vehicles have regulations re fuel tanks/filler necks etc to enable them to all use, without exception, every publicly available filling station in the UK. The pumps are also required to meet a specification for dispensing the fuel. Obvious really.
Is electricity that different? Specify the cable size and flow rate, or a range of cable sizes and flow rates which must be provided at every charging station receiving planning approval in the UK. Even specify AC "pumps" and DC "pumps".
Let the fancy "connector" bit be the problem of the vehicle manufacturer. If they want to have their own particular bespoke connector fine, but if it doesn't accept a standard dispensation of electricity from a standard UK charging point "pump", then they provide an adaptor so it does.
