A computer system (106) comprising processing circuitry (108) configured to: detect an isolation fault of an electrical energy storage system (102) comprising multiple electrical energy storage packs (104) connectable to a voltage bus (110) for providing power to an electric load (112); determine a subset (124) of at least one of electrical energy storage pack that can be disconnected from the voltage bus (110) without violating present power requirements for the electric load, wherein the following steps are repeated for each subset of at least one electrical energy storage pack until an isolation fault is detected in an electrical energy storage pack (104) of the electrical energy storage system (102), or until all subsets of at least one electrical energy storage pack have been tested: disconnect a present subset of at least one electrical energy storage pack from the voltage bus; perform isolation fault check on the disconnected subset of at least one electrical energy storage packs while the other subsets of at least one electrical energy storage pack remain connected to the voltage bus, and provide a control message indicating the outcome of the isolation fault test.
