Abstract
A working machine having a dump body configured to carry material. The working machine includes an electric drive line including an electric traction machine powered by a battery pack or a fuel cell; a fuel supply system including a fuel tank configured to store gaseous or liquid fuel, the fuel supply system being separate and independent of the electric drive line; a catalytic heater configured to produce heated gases using the fuel from the fuel tank; a dump body heating system configured to receive the heated gases from the catalytic heater to heat the dump body. The working machine further includes a control system including processing circuitry configured to, in response to identifying a predefined condition, activate the catalytic heater by supplying fuel from the fuel tank.

A working machine having a dump body configured to carry material, the working machine comprising:
- an electric drive line comprising an electric traction machine powered by a battery pack or a fuel cell;
- a fuel supply system including a fuel tank configured to store gaseous or liquid fuel, the fuel supply system being separate and independent of the electric drive line;
- a catalytic heater configured to produce heated gases using the fuel from the fuel tank;
- a dump body heating system configured to receive the heated gases from the catalytic heater to heat the dump body;
- and
- a control system comprising processing circuitry configured to:
- determine a predefined condition associated with a risk of material adhering to the dump body;
- in response to identifying the predefined condition, activate the catalytic heater by supplying fuel from the fuel tank;
- and
- in response to identifying an absence of the predefined condition, deactivate the catalytic heater by ceasing the supply of fuel from the fuel tank.
