Abstract
A charge circuit interrupt device comprises a ground fault interrupt module, a current generation module and a current injection module. The ground fault interrupt module disconnects a load from a charging source when a current imbalance exceeds a threshold. The current generation module generates a balancing current based on the current imbalance. The current injection module inputs the balancing current into the charging source to oppose the current imbalance. The charge circuit interrupt device may further include an input balance disable control module that disables the current generation module from generating the balancing current when the current imbalance exceeds the threshold, and a current isolation module that isolates the charging source and the ground fault interrupt module, the current generation module and the current injection module.
