SMART VEHICLE RESCUE BATTERY APPARATUS

摘要

A smart vehicle rescue battery apparatus includes a battery unit, a first switch unit, a second switch unit, a third switch unit, a fourth switch unit, a control unit and a voltage polarity detection unit. The first switch unit and the fourth switch unit are turned on, when the connection between the first switch unit and the third switch unit is judged to be a positive pole and when the connection between the second switch unit and the fourth switch unit is judged to be a negative pole. The second switch unit and the third switch unit are turned on when the connection between the first switch unit and the third switch unit is judged to be the negative pole and when the connection between the second switch unit and the fourth switch unit is judged to be the positive pole.
