A road construction machine in the form of a road paver or a feeder vehicle for conveying paving material to a road paver, the road construction machine being self-propelled and having a primary drive source, a hopper, at least one working unit and at least one electric consumer for heating the working unit, the road construction machine having an energy supply system with at least one electrical energy storage which can be charged by means of electric current generated outside the road construction machine and is present on the road construction machine as an internal power source for direct current supply to the electric consumer. Furthermore, the disclosure relates to the use of such an energy storage for direct current supply to an electric consumer of a road construction machine.
A road construction machine in the form of a road paver or a feeder vehicle for conveying paving material to a road paver, the road construction machine being self-propelled and comprising a primary drive source, a hopper, at least one working unit and at least one electric consumer arranged and configured to heat the working unit, wherein the road construction machine comprises an energy supply system with at least one electrical energy storage which can be charged by means of electric current generated outside the road construction machine and which is present on the road construction machine as an internal power source for direct current supply to the at least one electric consumer and wherein the road construction machine comprises a pump transfer gearbox and hydraulic pumps connected thereto, the electrical energy storage being configured for supplying power to the at least one electric consumer independently of the operation of the pump transfer gearbox.
A road construction machine in the form of a road paver or a feeder vehicle for conveying paving material to a road paver, the road construction machine being self-propelled and comprising a primary drive source, a hopper, at least one working unit and at least one electric consumer arranged and configured to heat the working unit, wherein the road construction machine comprises an energy supply system with at least one electrical energy storage which can be charged by electric current generated outside the road construction machine, wherein the at least one electrical energy storage is present on the road construction machine as an internal power source for direct current supply to the at least one electric consumer and wherein the at least one electrical energy storage comprises a battery, the battery being located in an area of the at least one electric consumer within a heat-insulating housing.
