Abstract

A computer system (100; 800) for performing a weld check in a traction voltage system (10), the computer system (10) comprising processing circuitry (102; 802) configured to: open a switch (22, 24) connected to the traction battery (20) and an electrical load (40) of the traction voltage system (10); measure a first voltage, V1, between the traction battery (20) and ground reference (30), the first voltage, V1, being measured at a battery side (10-1) of the traction voltage system (10) in relation to the switch (22, 24); measure a second voltage, V2, between the electrical load (40) and ground reference (30), the second voltage, V2, being measured at a load side (10-2) of the traction voltage system (10) in relation to the switch (22, 24); and compare the first and second voltages, V1, V2, to determine the presence of a weld in the switch (22, 24).
