BATTERY CHARGING AND RECOVERY REPRODUCING DEVICE PERFORMING AUTOMATIC CHARGING BY DETECTING BATTERY CONNECTION STATE OF BATTERY CHARGER AND RECOVERY REPRODUCING PLAYER AND SWITCHING POLARITY AUTOMATICALLY

摘要

PURPOSE: A battery charging and recovering apparatus is provided to normally operate by automatically switching an output polarity of the battery charging and recovering apparatus according to a connection state. CONSTITUTION: A main control unit(10) controls an output circuit according to various input and output conditions and states. An output reversible control unit(60) connects and blocks a battery(110). An output mode control unit(70) controls a circuit of an output unit according to a charging mode or a recovery reproducing mode. A battery connection state and display device(80) transmits a detection signal to detect a battery state to a microcontroller(11). A recovery reproducing pulse generating unit(90) generates a recovery reproducing pulse to the battery when the recovery reproducing mode is selected.
