ABSTRACT:
A lubricating oil heater apparatus for an electric motorcar enabling an efficient running in viewpoint of electric power consumption. The electric motorcar is run by driving force of an electric motor transmitted to wheels through a power transmission and has a charge condition detecting device for detecting the charge condition of a battery when the battery can be charged, an oil temperature detecting device for detecting temperature of a lubricating oil in the power transmission, a heating device for heating the lubricating oil in the power transmission, and a heating control device for controlling operation of the heating device. The heating control device operates the heating device when the charge condition detecting device detects a predetermined charge condition and the oil temperature detecting device detects an oil temperature below a predetermined value.
