    • Disclosed herein is a battery pack having a plurality of battery cells or unit modules ('unit cells'), which can be charged and discharged, mounted in a pack case, wherein the unit cells are stacked in a direction (a Z direction) in which the unit cells are sequentially stacked in parallel to a ground in a state in which a spacing distance for coolant flow is provided between the respective unit cells to constitute a battery module, two or more battery modules are arranged in a horizontal direction (an X direction) on the plane with respect to a coolant introduction direction in which a coolant is introduced through a coolant inlet port in a state in which flow of the coolant between the battery modules is restrained to constitute a battery module group, the pack case is provided with a flow space ('a coolant introduction part') extending from the coolant inlet port to the battery module group and another flow space ('a coolant discharge past') extending from the battery modules group to a coolant outlet port, and a coolant flow channel defined between the coolant introduction part and the coolant discharge part is configured to have a structure in which the coolant, introduced through the coolant introduction part, cools the battery modules while passing through the specific battery modules in a vertical direction (a Y direction) on the plane and is discharged through the coolant discharge part.
    • 这里公开了一种电池组,其具有可以被充放电的多个电池单元或单元模块(“单元电池”),其安装在包装盒中,其中,单元电池沿(Z方向)方向 其中单元电池在各个单元电池之间设置有用于冷却剂流动的间隔距离的状态下平行于地面顺序地堆叠以构成电池模块,两个或更多个电池模块沿水平方向(X 方向)相对于在电池模块之间的冷却剂的流动被限制以构成电池模块组的状态下通过冷却剂入口引入冷却剂的冷却剂引入方向,提供包装盒 具有从冷却剂入口端口延伸到电池模块组的流动空间(“冷却剂引入部分”)和从电池模块组延伸的另一个流动空间(“冷却剂排放过去”) 限定在冷却剂引入部和冷却剂排出部之间的冷却剂流动通道被构造成具有其中通过冷却剂引入部引入的冷却剂在通过特定电池的同时冷却电池模块的结构 模块在平面上沿垂直方向(Y方向),并通过冷却剂排出部排出。
