A test system for a battery pack, the battery pack having at least first and second battery modules, comprising: a high voltage service disconnect assembly having a housing including a stationary housing and a removable housing configured to be removable from the stationary housing, first and second conductive pins (160, 162), and an electrically-actuated switch; the removable housing being configured to secure the first and second conductive pins (160, 162) therein, the electrically-actuated switch being electrically coupled in series between the first and second conductive pins (160, 162), the electrically-actuated switch being disposed in the removable housing, the first conductive pin being electrically coupled to a voltage terminal of the first battery module when the removable housing is disposed in the stationary housing; the first conductive pin being electrically decoupled from the voltage terminal of the first battery module when the removable housing is removed from the stationary housing; the second conductive pin being electrically coupled to a voltage terminal of the second battery module when the removable housing is disposed in the stationary housing; the second conductive pin being electrically decoupled from the voltage terminal of the second battery module when the removable housing is removed from the stationary housing; a microprocessor operably coupled to the electrically-actuated switch and a sensor (90, 100, 110, 120), the microprocessor configured to generate a first signal to induce the electrically-actuated switch to have a closed operational position to electrically couple the first battery module to the second battery module; the sensor (90, 100, 110, 120) configured to generate a second signal associated with the battery pack; and the microprocessor configured to stop generating the first signal to induce the electrically-actuated switch to have an open operational position to electrically decouple the first battery module from the second battery module when the second signal is greater than a threshold level. a high voltage service disconnect assembly having a housing including a stationary housing and a removable housing configured to be removable from the stationary housing, first and second conductive pins (160, 162), and an electrically-actuated switch; the removable housing being configured to secure the first and second conductive pins (160, 162) therein, the electrically-actuated switch being electrically coupled in series between the first and second conductive pins (160, 162), the electrically-actuated switch being disposed in the removable housing, the first conductive pin being electrically coupled to a voltage terminal of the first battery module when the removable housing is disposed in the stationary housing; the first conductive pin being electrically decoupled from the voltage terminal of the first battery module when the removable housing is removed from the stationary housing; the second conductive pin being electrically coupled to a voltage terminal of the second battery module when the removable housing is disposed in the stationary housing; the second conductive pin being electrically decoupled from the voltage terminal of the second battery module when the removable housing is removed from the stationary housing; a microprocessor operably coupled to the electrically-actuated switch and a sensor (90, 100, 110, 120), the microprocessor configured to generate a first signal to induce the electrically-actuated switch to have a closed operational position to electrically couple the first battery module to the second battery module; the sensor (90, 100, 110, 120) configured to generate a second signal associated with the battery pack; and the microprocessor configured to stop generating the first signal to induce the electrically-actuated switch to have an open operational position to electrically decouple the first battery module from the second battery module when the second signal is greater than a threshold level.
