Abstract

Systems of an electrical vehicle and the operations thereof are provided. Inflow current occurs when components of differing voltage are connected absent mitigating components. Batteries and other components may be damaged by unrestrained inflow current. By performing a pre-charge, a battery line is gradually brought up to the voltage source potential. Additionally, by determining the observed voltage, while a lesser voltage is applied, to a connected component, a determination may be made if charging should or should not continue. If the observed voltage is less than that applied, a problem may be present and charging discontinued. As a result, high-voltage current that may be inadvertently exposed may be curtailed.
