Embodiment 1

[0026] According to an embodiment of the present invention, an embodiment of a control method of a motor cooling system is provided. It should be noted that the steps shown in the flow charts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0027] figure 1 is a flowchart of a control method of a motor cooling system according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0028] Step S102, detecting the temperature of the motor and the temperature of the motor controller.

[0029] In the above steps, it can be detected by the temperature sensor installed inside the motor and inside the motor controller. After the temperature sensor inside the motor detects the temper...

Embodiment 2

[0081] According to an embodiment of the present invention, an embodiment of a control device for a motor cooling system is provided, image 3 is a schematic diagram of a control device of a motor cooling system according to an embodiment of the present invention, such as image 3 As shown, the device includes:

[0082] The detection module 30 is used for detecting the temperature of the motor and the temperature of the motor controller.

[0083] In the above device, it can be detected by the temperature sensor installed inside the motor and inside the motor controller. After the temperature sensor inside the motor detects the temperature of the motor, it can transmit the temperature of the motor to the motor controller, and then controlled by the motor. Together, the controller transmits the motor temperature and the motor controller temperature to the controller of the motor cooling system.

[0084] The first speed regulation module 32 is used to control the speed of the c...

Embodiment 3

[0099] According to an embodiment of the present invention, an embodiment of a motor cooling system is provided, Figure 4 is a structural diagram of a motor cooling system according to an embodiment of the present invention, such as Figure 4 As shown, the system includes:

[0100] The temperature sensor 40 is used to detect the temperature of the motor and the temperature of the motor controller.

[0101] The controller 42 is connected with the temperature sensor, and is used to adjust the speed of the cooling water pump when the temperature of the motor and the temperature of the motor controller meet the first preset condition; when the temperature of the motor and the temperature of the motor controller meet the second preset condition In the case of certain conditions, the speed control of the cooling fan is carried out.

[0102] What needs to be explained here is that the cooling control of the motor in the prior art usually adopts the open / pipe mode, that is, a tempe...

Abstract

The invention discloses a motor cooling system, a control method, a device and an electric vehicle. The control method comprises the step that the motor temperature and the motor controller temperature are detected; speed adjusting control is conducted on a cooling water pump when the motor temperature and the motor controller temperature meet the first preset condition; and speed adjusting control is conducted on a heat dissipation fan when the motor temperature and the motor controller temperature meet the second preset condition. According to the control method, the technical problem of large energy consumption of a motor cooling system of an electric vehicle in the prior art is solved.

Description

technical field [0001] The invention relates to the field of electromechanical control, in particular to a motor cooling system, a control method, a device and an electric vehicle. Background technique [0002] The motor is the main driving component of new energy vehicles (such as electric vehicles). Only by ensuring the normal operation of the drive motor system can the safe driving of the vehicle be guaranteed. Since the temperature of the motor and the motor controller will gradually increase during the working process, when the temperature exceeds a certain threshold, the motor system cannot work normally, so the motor system must be equipped with a cooling system. Only the normal operation of the cooling system can ensure the stable operation of the motor system. [0003] In the cooling control strategy of the existing electric vehicle driving motor, the "on / off" control method is mostly adopted, that is, when the temperature of the driving motor exceeds a certain tem...
