Commercial vehicle having a temperature-regulating system

Abstract

The invention relates to a commercial vehicle, in particular a battery-electrically driven trailer for coupling to a semitrailer tractor, having a system (10) for regulating the temperature of the power electronics in battery-electrically driven trailers, comprising an HV battery unit (20), an electrical drive unit (7) driven by the electrical energy of the HV battery unit (20), and a control unit (30), wherein the system (10) has at least one heat exchanger (2) and at least one coolant pump (3), characterised in that the system (10) has at least one cooling circuit (9) of a coolant for controlling the temperature of the HV battery unit (20), the electric drive unit (7), and the control unit (30), wherein the cooling circuit (9) selectively cools or heats the HV battery unit (20), the electric drive unit (7), and the control unit (30) depending on an operating temperature of the components to be temperature-controlled and an ambient temperature of the system (10).
