Problems solved by technology

Although the heat dissipation control logic of the charger using this cooling fan is relatively simple and the cost is low, but in the charging process, as long as one charging module in the charger is working, the cooling fan of the charger will run at full speed, causing unnecessary power loss, resulting in higher noise

Embodiment Construction

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] The heat source of the charger is mainly the heat generated by the charging module. The charger includes a cooling fan and several charging modules. The cooling fan is an EC fan. Usually, the EC fan is evenly distributed in the center of the charging module group. Each charging module corresponds to There are different position numbers, and a cooling fan is installed inside ea...

Abstract

The invention discloses a method and system for controlling the rotating speed of a cooling fan of a charger and the charger. The method comprises the following steps: acquiring the position number of a charging module in a working state, and obtaining the heating weight corresponding to the charging module in the working state according to the position number of the charging module in the working state; acquiring the rotating speed of the cooling fan in the charging module in the working state; acquiring the environment temperature of the charging module, and acquiring an environment temperature coefficient according to the environment temperature; acquiring the total output power of the charging module in the working state, and obtaining a total output power coefficient according to the total output power; and inputting the heating weight corresponding to the charging module in the working state, the rotating speed of the cooling fan in the charging module in the working state, the environment temperature coefficient and the total output power coefficient into an EC fan rotating speed percentage model to obtain the EC fan rotating speed percentage. According to the method and system, the optimal control of the rotating speed of an EC fan of a charger system can be achieved, and the optimal cooling of the charger system and the lowest system noise can be achieved.

Description

technical field [0001] The invention belongs to the technical field of chargers, and in particular relates to a method for controlling the speed of a cooling fan of a charger, a control system and a charger. Background technique [0002] At present, most of the cooling fans used in chargers on the market are non-adjustable centrifugal fans or axial flow fans. Although the heat dissipation control logic of the charger using this cooling fan is relatively simple and the cost is low, during the charging process, as long as one charging module in the charger is working, the cooling fan of the charger will run at full speed, causing unnecessary power loss, resulting in higher noise. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the present invention provides a cooling fan speed control method of a charger, a control system and a charger, which can achieve the best EC fan speed control of the charger system and achieve the best c...
