EVSE questions

A major player in the EVSE market has kindly consented to provide some technical training for the electrical installation tutors at a training centre where I often tutor part-time. I imagine it is not entirely motivated by altruistic considerations but at least it gives an opportunity for the tutors and myself to get some kind of grasp on the various products on offer and where this particular manufacturer sees the direction of travel for EVSE. I am already aware that the company is moving away from products that rely on the installation of earth electrodes in PME situations and are placing considerable focus on load management. Is there any particular question that you would ask them given the opportunity?

  • I have been looking at your graph carefully, as well as the error band figure. Presumably, the line shown is a least-squares regression, this should show the statistical significance as well, which is low. In other words, one cannot make any predictions about any future temperature. NASA talks about the actual ice cover each year and it varies hugely, again it is not possible to predict what will happen. Generally, this is called weather.
