Battery array safety covers for energy storage system

摘要

An energy storage system comprising at least one energy storage module adapted to supply electrical energy to a hybrid vehicle. The energy storage module comprises an enclosure and at least one battery array located within the enclosure. The battery array also includes a voltage sense board having a plurality of bus bars disposed therein. The bus bars connect a positive terminal of a first battery cell to a negative terminal of a second battery cell. The voltage sense board has missing final bus bars in designated locations of the voltage sense board to limit the exposed voltage to 50 volts during initial assembly. The final bus bars are installed last in conjunction with safety covers which have overlap portions to cover the installed final bus bars.

1. An energy storage system, comprising:
at least one energy storage module adapted to supply electrical energy to a hybrid vehicle, the energy storage module comprising:
a primary enclosure; andat least one battery array located within the primary enclosure; wherein the at least one battery array comprises:
a voltage sense board;a first subgroup of battery cells, the first subgroup including a first battery cell adjacent to a second battery cell;a second subgroup of battery cells, the second subgroup including a third battery cell;a plurality of bus bars disposed within the voltage sense board, a first bus bar of the plurality of bus bars connecting a positive terminal of the first battery cell to a negative terminal of the second battery cell;at least one final bus bar coupled to and extending away from a first insulative cover, the final bus bar connecting the negative terminal of the second battery cell to a positive terminal of the third battery cell;wherein the voltage of the first subgroup of battery cells and the voltage of the second subgroup of battery cells is not greater than 50 volts.
