The invention relates to a truck mixer (1) comprising a chassis (2) and an arrangement (3), wherein the chassis (2) has at least one drive axle (5) driven by a chassis drive (4) for the travelling forward movement of the truck mixer (1), and wherein the arrangement (3) has a mixer drum (7) rotationally driven by a drum drive (6). The object of the invention is to provide an improved truck mixer which allows for a significant reduction or prevention of waste gases during the travelling of the truck mixer and when filling and emptying the mixer drum. According to the invention, the chassis drive (4) and the drum drive (6) are electrical drives, wherein a high-voltage battery (8) of the truck mixer (1) is designed to supply both the chassis drive (4) and the drum drive (6) with electrical energy, wherein the truck mixer (1) has a low-voltage battery (9) associated with the arrangement (3), which is provided to supply auxiliary consumers (14, 15, 16, 17, 18, 19, 20, 21, 22) of the arrangement (3) with electrical energy, wherein the truck mixer (1) has a DC/DC voltage converter (10) which is connected to the high-voltage battery (8) on the input side and to the low-voltage battery (9) and the auxiliary consumers (14, 15, 16, 17, 18, 19, 20, 21, 22) on the output side, and which is designed to charge the low-voltage battery (9) with electrical energy from the high-voltage battery (8).
