The invention discloses a battery system and an electric vehicle having the same. The battery system comprises a mounting shell and a plurality of battery modules. The mounting shell comprises: a chassis; a cover plate; a mounting column; and a sealing piece which comprises a sealing part arranged on the mounting column, a connecting part connected with the sealing part and the mounting column, wherein the sealing part is in seal contact with the cover plate or the chassis or in seal contact with the mounting column and the second wall surface. The battery backup unit of each 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 the body 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 a negative busbar, wherein the negative busbar body of the negative busbar is located between the center line of the negative tab and the second end surface. The battery system has higher energy density and electric quantity under the condition that the sealing performance and the mounting strength are ensured.

    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和多个电池模组。所述安装壳包括底盘;盖板;安装柱;以及密封件,密封件包括:密封部,密封部设在安装柱上;和连接部,连接部与密封部和安装柱相连,密封部与盖板或底盘密封接触和/或安装柱与第二壁面密封接触。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。电池系统在确保密封性能和安装强度的情况下,具有更高的能量密度和电量。
