We wish to design a electric car battery charger for connection to single phase , 230VAC mains. Therefore the maximum input current that we are allowed to draw is 16 Amps. However, this must be fused. The fuse must be rated 16 Amps or less for use on single phase mains. The maximum input current has to be at least 10% less than the fuse rating to avoid false fuse tripping. Therefore, the maximum input current we are allowed is 14.4 Amps.
Therefore the maximum input power that we can design for is 230VAC * 14.4A = 3312W. With an efficiency of 90%, this means our charger output can be no more than 2.98kW , due to its connection to single phase mains. Do you agree?
