Embodiment 1

[0057] like Figure 1 to Figure 14 As shown, this embodiment provides an integrated electric air compressor, including a motor 1, a motor controller 2 and a compressor assembly 3, wherein the motor 1 and the motor controller 2 form a motor drive system, and the motor 1 is a compressor The assembly 3 provides power, and the motor 1 includes a housing 11 with a first liquid cooling channel 113 having a first liquid inlet 111 and a first liquid outlet 112, a stator assembly 12, a rotor assembly 13, a front end cover 14 and a rear end cover 15. The stator assembly 12 and the rotor assembly 13 are installed in the casing 11, the rotor assembly 13 includes a rotating shaft 131, and the end of the rotating shaft 131 protrudes from the front end cover to form a shaft extension end 1311;

[0058] The motor controller 2 is used to control the operation of the motor, including a drive module 22, a control circuit board 23, a capacitor module 24, and a second liquid cooling channel 213 wi...

Embodiment 2

[0076] like Figure 15 As shown, a fuel cell air intake system of the present invention includes an air filter, a muffler, an integrated electric air compressor, an air cooler and a humidifier, and the external cold air passes through the filter, the muffler, the integrated electric air Compressed air is supplied to the fuel cell stack after the compressor, air cooler and humidifier. like Figure 16 As shown, the self-starting integrated air compressor adopts the integrated electric air compressor described in Embodiment 1, which also includes a low-voltage power supply, and the low-voltage power supply passes through the DC-DC converter 4 installed in the box. Converting to high voltage provides the motor drive system with working energy in the start-up phase.

[0077] like Figure 17 As shown, the DC-DC converter is connected with a control switch 200. When the fuel cell system reaches the normal operating voltage, the DC-DC converter 4 is automatically disconnected throu...

Abstract

The invention discloses an integrated electric air compressor and a fuel cell air intake system using the same. The start-up integrated electric air compressor integrates a compressor assembly, a motor, a motor controller and a DC-DC converter , the DC-DC converter is set in the box of the motor controller, the motor controller is connected to the rear end cover of the motor, and the compressor assembly is mechanically connected with the motor, so that the air compressor has a self-starting function, reducing The use of connectors and pipelines, high degree of integration and modularization, compact size and easy installation, reduce system complexity and manufacturing costs, reduce the number of parts, reduce the impact of exposed pipelines on the system, reduce system assembly complexity, and reduce electromagnetic interference .

Description

Technical field: [0001] The invention relates to an integrated electric air compressor, in particular to a fuel cell air intake system in an electric vehicle. Background technique: [0002] The fuel cell system uses the electrochemical reaction between the hydrogen stored in the gas cylinder and the oxygen from the air to generate electrical energy, which provides a power source for electrical equipment, generally including a fuel cell stack and a fuel cell air intake system. The air intake system of the fuel cell includes an air compressor, an air filter, a muffler and a humidifier, wherein the air compressor is used to compress air and provide the compressed air to the battery stack; the air filter is used to purify the air and block the The dust and other impurities enter the intake system; the muffler eliminates the noise caused by the rapid flow of air; and the humidifier uses the moisture generated in the battery stack to humidify the compressed air. [0003] The air ...
