Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] The charging device of the present invention can change the speed of the cooling fan for the battery pack and the charging module by detecting parameters such as the running time of the fan, the internal resistance of the battery pack, the temperature of the charging module, and the voltage of the battery pack during the charging process of the battery pack. Or a combination of multiple parameters is used as the change condition of the fan speed, according to different stages of the charging process, the speed of the cooling fan is reasonably adjusted, the noise of the fan is reduced, and the energy consumption of the fan is reduced.

[0041] Such as figure 1As shown, the cooling and charging device for the battery pack includes a charging module for the battery pack, a cooling fan for cooling the charging module and the battery pack, a power supply module for t...

Abstract

The invention discloses a cooling and charging device and method for a battery pack, comprising a charging module for charging the battery pack, a cooling fan, a power supply module, and a cooling fan control module. The cooling fan control module is used to control the cooling of the cooling fan, and is connected with The cooling fan is connected. In the charging process, the present invention can change the speed of the cooling fan for the battery pack and the charging module by detecting parameters such as the running time of the cooling fan, the internal resistance of the battery pack, the temperature of the charging module, and the voltage of the battery pack. The combination of parameters is used as the change condition of the speed, and according to the different stages of the charging process, the speed of the cooling device can be adjusted reasonably, the noise can be reduced, and the energy consumption can be reduced, which has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of control circuits, in particular to a cooling and charging device and method for a battery pack. Background technique [0002] For the charging of battery packs, there are many restrictive factors, and the most important factor is temperature. In order to shorten the waiting time between battery pack discharge and charging, the traditional charging device for battery packs, in order to ensure that the battery pack in the charging device or The charging module is at a suitable working temperature, and fans are often used to cool down. For some high-power battery packs, due to the high heat generation, high-power fans need to be used to generate relatively large noise. Studies have shown that when the battery pack is charging Appropriate temperature can shorten the charging time of the battery pack, and the speed of the existing high-power fan provided with the charging device is fixed during the charging pr...
