The invention discloses a battery system and an electric vehicle having the same. The battery system comprises a mounting shell, a battery module, a heat exchange device and an elastic piece. A mounting cavity is formed in the mounting shell; the elastic piece is arranged between the heat exchange device and the first wall surface of the mounting cavity and/or between the battery module and the second wall surface of the mounting cavity, is in contact with the heat exchange device and the mounting cavity and is in a compressed state. The battery backup unit of the battery module comprises: a plurality of batteries, wherein each battery comprises a body and positive and negative tabs, and the center lines of the positive and negative tabs are positioned between the first end surface of thebody and the length center line; a positive busbar, wherein the positive busbar body of the positive busbar is positioned between the center line of the positive tab and the second end surface; and anegative busbar, wherein the negativebusbar body of the negative busbar is located between the center line of the negative tab and the second end surface. The battery system has the advantages of being high in energy density, large in electric quantity, high in heat transfer efficiency, stable in performance, long in service life, high in safety and the like.

    本发明公开了一种电池系统和具有该电池系统的电动车辆。所述电池系统包括安装壳、电池模组、换热装置和弹性件。安装壳内具有安装腔;弹性件设在换热装置与安装腔的第一壁面之间和/或设在电池模组与安装腔的第二壁面之间且与它们接触,弹性件处于压缩状态。电池模组的电池模块包括多个电池,每个电池包括本体和正负极耳,正负极耳的中心线位于本体的第一端面与长度中心线之间;正极汇流排,正极汇流排的正极排体位于正极耳的中心线与第二端面之间;和负极汇流排,负极汇流排的负极排体位于负极耳的中心线与第二端面之间。根据本发明实施例的电池系统具有能量密度高、电量大、传热效率高、性能稳定、使用寿命长、安全性高等优点。
