1. An air-conditioning system for air-conditioning an electrified motor vehicle which has an interior and a high-voltage accumulator, the air-conditioning system comprising:
an air-conditioning installation; and
an electronic control unit,
wherein the air-conditioning installation is configured to air-condition both the interior and the high-voltage accumulator, and
wherein the control unit has a preconditioning module that implements a preconditioning mode during charging of the parked vehicle before a journey begins, wherein in the precondition mode:
(a) the control unit is configured to predict at least; the length of the route and an outside temperature over the length of the route, and
(b) the high-voltage accumulator is operated as:
(i) a heat accumulator when the predicted outside temperature over the length of the route is lower than the heating threshold target temperature required by the high-voltage accumulator, and
(ii) a cold accumulator when the predicted outside temperature over the length of the route is greater than the heating threshold target temperature required by the high-voltage accumulator.
