Networks should look at the "
Freewire Boost" units that BP Pulse have started installing.
A 120kW chargepoint that only needs a 27kW connection due to having a 160kW onboard battery it can trickle charge between vends.
Yes, the superhub approach with dozens of chargers in one location but well away from motorway routes may at first seem like progress, but you have to ask what is needed by EV drivers and what makes a sustainable EV charging business model?
Multiple reliable charging facilities offering food and rest facilities directly off the motorways and major trunk routes is what people want and is needed to encourage EV use.
The business model must be based on maximising the use of each charger, and here, a provision which closely matches the need and can be expanded to match demand is more likely to be financially sustainable.
Also, making use of existing service areas as found at MSAs and other major service areas is clearly cheaper than reproviding these facilities on greenfield sites.
I suspect this is what government funding was meant to achieve and ecotricity got in early probably based on false promises and inaccurate financial modelling. I guess it would have looked odd for a government to throw money at the oil companies and also I expect the oil companies couldn't make the finances stack up at that time.
So what should happen now?
Dept of Transport need to model future EV traffic and work out where charging facilities will be needed over the next 20 years and then subsidies should only be given based on providing facilities on these sites. Every subsidy must be based on robust financial modelling which identifies how maintenance and refresh will be managed while still providing profits for investors.
Easy.
