An electric heating apparatus includes a power module, an electric heating unit, and a switching unit. The power module is adapted to be electrically connected to a battery for outputting electric energy. The electric heating unit includes multiple electric heating components electrically connected to the power module tor receiving and converting the electric energy into thermal energy. The switching unit is electrically connected between the power module and the electric heating unit, and is operable to control electrical connection between the power module and each of the electric heating components. Accordingly, the electric heating unit generates the thermal energy with a constant output power.
