An input surge voltage protection circuit for an on-board charging system in an electric vehicle EV, when the EV is plugged-in for charging from the utility grid, comprises first and second thermal fuses 201, 202 and first, second, third and fourth Surge Protection Devices (SPD) 203-206. The first thermal fuse is connected in series in an L line; the second thermal fuse connected in series in a N (neutral) line; the first Surge Protection Device connected between the L line and the N line; the second SPD connected to the L line; the third SPD connected to the N line; and the fourth SPD connected to a midpoint of the second SPD and the third SPD and an E (earth) line. The first, second and third SPDs may be Metal Oxide Varistors (MOV). The fourth SPD may be a Gas Discharge Tube (GDT).
