BATTERY CHARGE DEVICE AND CONTROL METHOD THEREOF |
摘要 |
<p>A battery charge device and a control method. The battery charge device includes a charging circuit (211) for charging a battery (25) based on a value of a charging current on a charging current set terminal (ISET), a charging current control circuit (212) for gradually regulating the value of the charging current based on a value of an equivalent resistance, and a general purpose register circuit (2411). The value of the equivalent resistance is controlled by a value of an output of the general purpose register circuit (2411). The control method includes a step of setting the value of the output of the general purpose register circuit (2411) based on a maximal load capability of a charge power supply (23) and a charging current needed by the battery (25), and a step of gradually regulating a value of a charging current supplied to the battery (25) based on the value of the output of the general purpose register circuit (2411).</p> |
