In order to be able to supply the traction drive on the one hand and the working unit (210) on the other hand with the energy required in each case independently of one another in a purely electrically driven vehicle (200), in particular a self-travelling working machine (200), a fully electric drive unit (100) is provided which supplies both, with a planetary gear unit (1) which is driven by two separately controllable electric machines (E1, E2) and thus, considered on its own, acts as a summing gear.Because of an additional power output (NA1), which is coupled to one of the two E-machines (E1) and/or the corresponding drive input into the planetary gear (1) with a fixed transmission ratio, the working unit (210) can be supplied via this power output (NA1), while the speed of the traction drive is independently controlled via the differential speed between the sun gear (2) and the ring gear (3), which are driven by the two E-machines (E1, E2).The sum of the planetary gear and the power output (NA1) thus acts primarily as a power divider gear.
