20080203975 | Integrated Circuit and Method for Preserving Vehicle's Battery Charge and Protecting Trailer Load - A method and integrated circuit for preserving a battery's charge and protecting electrical devices is disclosed. A maximum and a minimum battery voltage value at the output port are stored in a memory. A steady state battery voltage at the output port is measured and stored in the memory. A processor compares the measured steady battery voltage value to the maximum and the minimum battery voltage values. If the measured steady state battery voltage value is greater than the maximum battery voltage value, an over voltage state is reported by the processor. If the measured steady state battery voltage value is less than the minimum battery voltage value, a low battery voltage state is reported by the processor. | 08-28-2008 |

20080252264 | Battery Charger for Preventing Charging Currents from Overshooting During Mode Transition and Method Thereof - A battery charger for charging a battery through controlling a charging regulation circuit is provided. The battery charger includes a constant voltage mode controller, a current sensing unit, and a reference voltage generator. The constant voltage mode controller is for comparing a battery voltage of the battery with a first reference voltage to generate a regulation signal, and utilizing the regulation signal to control the charging regulation circuit to regulate a charging current applied to the battery. The current sensing unit is for monitoring the charging current to generate an error signal. The reference voltage generator is for setting the first reference voltage according to the error signal. By adding a voltage generator to the battery charger, the overshoot charging current will be reduced and the mode transition will become smooth. | 10-16-2008 |
