<p>Automated charging systems for vehicles having rechargeable batteries are in common use today. Such systems typically have exposed contacts or the need for additional circuitry to move the contacts. The subject system includes circuitry which allows the charge receiving member (130) to be only connected to the battery (110) during charging. The charging system (100) produces a charging signal in response to a low battery. A microprocessor (240) receives the charging signal and responsively produces a 'pulse' signal. A second transistor switch (345) receives the 'pulse' signal and responsively energizes a charging contactor coil (305). In response to the charging contactor coil being energized, contacts (200a, 200b, 300a, 300b) controllably block power from the battery (110) to the motor (115) and pass power from the receiving member (130) to the battery (110).</p> |
