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?

  • Andy,

    Electric traction (using batteries or hydrogen as the transfer medium or direct connection to overhead conductors) offers benefits in urban areas where there is significant slow and stop/start movement. Energy can be recovered by regenerative breaking and engine idling losses are removed. There is also an air quality improvement, although with modern engines the emmisions are really very low. If fossil fuels are burnt in a large power station it is easire to contol the combustion and emisions. For long haul where transmission losses are more significant diesel can be a good option as more optimal loading of the engine is possible.
