Battery charging method and apparatus |
摘要 |
A battery charger employing the gassing point of a lead-acid battery to determine the end of charge time and voltage. A charging level sensor takes two voltage samples of a predetermined time period to determine the change in voltage rate. If the change in voltage rate exceeds a predetermined amount the batteries are considered to be gassing. The batteries are further charged for a predetermined amount of time after the gassing phase has been entered. The invention provides a load management control function to provide a safe DC charge voltage when a hall effect sensor senses a DC load. The charger is cut off if a house load is used while the battery is being charged. The charging circuit achieves different end of charge voltages depending on a user selected battery type. The battery charger is a constant voltage temperature compensated current limited charger.
