Battery pack having stable measuring unit
First Claim
1. A battery pack comprising:
- a battery module comprising;
(a) a battery cell stack having a plurality of series-connected battery cells or unit modules which are stacked in a lateral direction with each battery cell or unit module oriented upright, the battery cell stack being provided at the front thereof with bus bars for connecting electrode terminals of the battery cells to external input and output terminals;
(b) voltage measuring members provided at ends thereof with connection terminals that are electrically connected to electrode terminal connection parts of the battery cells located at the front and rear of the battery cell stack to measure voltages of the battery cells or the unit modules;
(c) an upper case that covers the top of the battery cell stack and parts of the front and rear of the battery cell stack, the upper case being provided with mounting parts for inserting and mounting the voltage measuring members therein, wherein the mounting parts are formed respectively at a front upper part and a rear upper part of the upper case such that the mounting parts are upwardly open; and
(d) a lower case coupled to the upper case while covering the bottom of the battery cell stack and parts of the front and rear of the battery cell stack, the lower case being provided at the front thereof with external input and output terminals;
a voltage measuring member that measures voltage at an electrode terminal connection part of the battery cells or the unit modules;
a voltage measuring circuit that connects the voltage measuring member to a Battery Management System (BMS);
a temperature measuring member that measures temperature of the battery cells or the unit modules, wherein the temperature measuring member is mounted between the battery cells or the unit modules;
a temperature measuring circuit that connects the temperature measuring member to the BMS, the temperature measuring circuit being separated from the voltage measuring circuit, wherein the temperature measuring circuit is spatially separated from the voltage measuring circuit; and
the BMS electrically connected to the voltage measuring member to control operation of the battery module.
