Abstract: A voltage control apparatus checks a battery voltage when an automotive generator gradually increases its output to be within a predetermined range after temporarily stopping the generator. Then, the battery voltage is picked up to calculate the charge rate. Further, a first charge rate and a first residual capacity of the battery is memorized when the engine is stopped. Periodically, a pseudo-open circuit voltage is checked when a charge/discharge current fits within a predetermined small range while the engine is not running, and a second charge rate calculated based on the checked pseudo-open circuit voltage. A second residual capacity is calculated using the first charge rate, the first residual capacity and the second charge rate.

Abstract: A circuit and method for charging a rechargeable cell is provided. The circuit includes a voltage regulator coupled serially between a power source and a rechargeable cell. The circuit further comprises a controller capable of both monitoring the power dissipation across the voltage regulator and altering the current flowing through the voltage regulator. When the power dissipation in the voltage regulator exceeds a predetermined threshold, the controller increases the current. Where the power source is a linear transformer, this increase of current will cause the transformer to become loaded. The loading causes the transformer output voltage to fall, thereby reducing the power dissipation in the voltage regulator below the predetermined threshold. If, however, the power dissipation does not fall below the predetermined threshold within a predetermined time following the increase of current, the controller will then reduce the current to a level low enough to cause the power dissipation in the voltage regulator to fall below the predetermined threshold. The circuit and method provide a way to rapidly charge batteries while ensuring that the voltage regulator is not subject to thermal compromise.
