NEW ENERGY AUTOMOBILE, DRIVING MOTOR OIL COOLING SYSTEM, AND CONTROL METHOD

WIPO Patent Application WO/2022/016745

A1

A new energy automobile, a driving motor oil cooling system, and a control method. The driving motor oil cooling system comprises a front-end cover (1) and a base (8). The front end cover (1) is provided with an oil inlet (11) and an oil outlet (12); an internal circulation space is provided with a temperature measuring element for measuring temperature of a stator and a winding, a speed measuring device for measuring a rotational speed of a driving motor, at least two flow guiding tubes (7) for guiding cooling oil to a component to be cooled, an adjusting device for adjusting the flow rate of the cooling oil entering the flow guiding tubes (7), and a controller (6). In the driving motor oil cooling system, different working conditions of the motor may be determined according to temperature data and rotational speed data, the flow rate of the cooling oil flowing through different flow guiding tubes (7) can be reasonably distributed according to actual conditions of the different working conditions, thereby implementing optimal oil capacity control under an optimal cooling effect, and reducing energy consumption; moreover, different parts of the motor are cooled in a targeted manner, thus improving the cooling effect.
