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.
