<p>The present invention relates to an intelligent battery charging device. According to a preferred embodiment, there is a battery charging device comprising a power converting part for converting the magnitude of a voltage and the amount of a current from a commercial power supply and thereby charging a battery, a voltage detecting part and a current detecting part that are electrically connected to an electric line between the power converting part and the battery so as to detect a charge voltage and a charge current that are provided to the battery, and a power controller for controlling the power converting part such that the charge voltage and the charge current detected by the voltage detecting part and the current detecting part assume constant voltage and current values, wherein the battery charging device comprises: a data storage part for storing battery characteristics data broken down by product code, said data relating to charge mode, rated capacity, rated voltage, allowable temperature, maximum current and minimum current that are needed according to the type of battery and the manufacturer; (Here, the charge code is a method of charging the battery, and is divided into constant-voltage mode, constant-current mode, voltage-current mode, pulse current mode, and floating charge mode.) a user input part for receiving and transmitting a predetermined product code recorded on the battery; a data retrieving part for retrieving the battery product code received from the user input part from the data storage part, thereby extracting battery characteristics data about the same product code; and a charge condition determining part for determining a command voltage and a command current for the battery charge in accordance with the battery characteristics data extracted from the data retrieving part, so as to transmit same to the power controller.</p> |
