Abstract

The power transmission apparatus may include a battery, a motor generator that is switchable between a driving state and a power generation state, at least a load, an inverter to switch the motor generator to any of the driving state and the power generation state, a charging state detecting means to detect a charged amount C of the battery, an absorbing horsepower detecting means to detect the absorbing horsepower Lp of the load, and a control device to switch the motor generator to any of the power generation state and the driving state by means of the inverter, based on the absorbing horsepower Lp detected by the absorbing horsepower detecting means and the charged amount C of the battery that is detected by the charging state detecting means.
