Abstract
A vehicle having an engine starter requires a huge amount of electric power so that when the remaining capacity of the battery is low, the engine starter cannot start the engine quickly. In order to maintain a minimum capacity of the battery necessary to start the engine quickly, an electric power supply apparatus is provided which includes a switching device for stopping a vehicle engine, a timer device for measuring elapsed time after engine stoppage, a capacity detector for detecting remaining capacity of a battery, vehicle equipment driven by the electric power from the battery, a switching member for turning off the power supplied from the battery to the vehicle equipment and a control device for controlling the switching member when the capacity of the battery is below a certain level and the timer device measures the elapsed time.
