Patent ID: 8728642

Claim:
An energy storage system, comprising: an energy storage module having a potential difference of at least 300 volts adapted to supply electrical energy to a hybrid vehicle, the energy storage module including a primary enclosure; a battery array located within the primary enclosure, the battery array having a plurality of battery cells; a high-voltage junction box mounted to the primary enclosure, the high-voltage junction box including at least one internal terminal electrically connected to the battery array by a plurality of internal high-voltage conductors, the high-voltage junction box also having at least one external terminal configured to electrically connect to at least one external high-voltage conductor; and a plug-in bussed electrical center formed of electrically insulative material and mounted in the high-voltage junction box, the plug-in bussed electrical center also having: one or more high-voltage contactors; at least one internal terminal connector rigidly extending away from the plug-in bussed electrical center and configured to electrically connect to the corresponding at least one internal terminal in the high-voltage junction box; and at least one external terminal connector rigidly extending away from the plug-in bussed electrical center and configured to electrically connect to the corresponding at least one external terminal in the high-voltage junction box; wherein the plug-in bussed electrical center is configured to electrically connect one or more of the internal terminal connectors with one or more of the external terminal connectors using the one or more high-voltage contactors.
