Reported in Autocar. Is this the answer?
This week I heard about a new portable charging station called an EV Rescue. In effect it’s a big, smart battery that rolls on wheels like an airport suitcase, made by a firm recently bought by Chargemaster, the UK’s biggest maker of charging stations.It is meant for big fleet owners or breakdown organisations, in fact the RAC is just beginning service trials with it. If your electric car conks (and you’re a member of the RAC) a nice man will plug this thing in and give you approximately a mile of charge for every minute. Special electronics plot the distance to your nearest dealer or charging point: a five-minute “tickle” may be all that’s needed to get you back on the road.
Now all we need is for these things to become miniaturised, and be portable in a boot like a gallon of gas, and for the stranded electric car owner, Bob will become your uncle.
