<p>PURPOSE: A battery pack is provided to improve heat-radiating performance, to reduce a temperature difference between cells, and to prevent deterioration of a battery cell by cooling heat generated from electronic components in a junction box by arranging a heat-sink structure in the junction box. CONSTITUTION: A battery pack(100) comprises a battery module(110) with a plurality of unidirectionally-aligned battery cells, a housing accepting at least one of the battery cells, and in which a flow path of the coolant is formed, and a junction box arranged on a specific site nearby the battery module, and having a through-hole(127) arranged to be parallel with the flow path. The housing comprises at least one inlet(137), and at least one outlet which are flow channel of the coolant.</p> |
