1results about How to "Reasonable speed" patented technology

This application provides a charging device, a charging cloud platform, and a charging system. The charging device includes a temperature controller and a temperature sensor. The temperature sensor detects the temperature of the charging device, and the temperature controller adjusts the temperature of the charging device. The charging device is used to: transmit temperature control data during the output of DC power, including the temperature from the temperature sensor and the corresponding rotational speed of the temperature controller; receive an empirical temperature control curve, which is a curve showing the relationship between the temperature of the charging device and the rotational speed of the temperature controller. The empirical temperature control curve is fitted based on temperature control data from at least two charging devices, including the charging device itself and other charging devices besides the charging device; and control the rotational speed of the temperature controller based on the empirical temperature control curve and the temperature from the temperature sensor. The solution provided in this application can reduce the R&D investment in temperature control characteristics, thereby reducing economic and labor costs.
