Abstract
A battery pack cooling and charging device includes a charging module for a battery pack, a cooling fan, a power source module and a cooling fan control module. The cooling fan control module is capable of controlling the cooling fan for cooling and is connected with the cooling fan. During the charging operation, a rotational speed of the cooling fan for cooling the battery pack and a charging module is changed by detecting parameters such as fan operation time, a battery pack internal resistance, a charging module temperature, and a battery pack voltage. The rotational speed of the cooling fan is reasonably adjusted, thus noise of the cooling fan is reduced and energy consumption is reduced according to different phases of the charging process by regarding one parameter or combinations of parameters as conditions for changing the rotational speed of the fan.
