The invention relates to an electric vehicle, in particular a construction machine, comprising a battery system (10) which has a high-energy battery (12) having at least one high-energy cell and a high-performance battery (14) having at least one high-performance cell, a first load strand (41), which has at least one actuating motor (31) for driving at least one actuating element of the electric vehicle, a second load strand (42), which has at least one traction motor (32) for driving at least one traction element of the electric vehicle, and a switching unit (60) which can be controlled in such a way that the high-performance battery (14) is connected electrically to the second load strand (42), that the high-performance battery (14) is connected electrically to the first load strand (41), and that the high-energy battery (12) is connected electrically to the first load strand (41). The invention also relates to a method for operating an electric vehicle according to the invention, wherein the high-energy battery (12) is separated electrically from the first load strand (41) as long as a temperature of the high-energy battery (12) remains below a specified limit value.
