Abstract

An illustrative embodiment of a cable joint integrity detection system for an electric vehicle includes an electric vehicle power conversion module; a fastener joint on the power conversion module; a vehicle accessory electrically engaged with the power conversion module at the fastener joint. a wire connector; a current sensor electrically engaged with the fastener connector; and a controller engaged with the current sensor, the current sensor transmitting a sensor signal to the controller to ensure connection integrity between the fastener connector and the vehicle wiring connector . A cable joint integrity detection method is also disclosed together.

Description

technical field [0001] The illustrative embodiments of the invention are generally directed to electric vehicles (EVs). More specifically, the illustrative embodiments of the present invention relate to a cable splice integrity detection system and method for detecting the integrity of a B+ terminal connector between a DC / DC (direct current / direct current) power conversion module and a B+ cable in an EV . Background technique [0002] In a hybrid or fully electric vehicle, a DC / DC power conversion module can perform the function of an alternator. The B+ cable can be used to connect the DC / DC power conversion module to the vehicle's 12V wiring connection. The B+ cable can be connected to the DC / DC power conversion module with a fastener connector (bolt and nut). However, cross-threading can compromise the integrity of the fastener joint. An insulating boot or plastic cover may be placed over the fastener joint to prevent accidental grounding. [0003] Due to the high cur...
