Integrated three-in-one control device for hydrogen fuel logistics vehicle

Abstract

The invention provides an integrated three-in-one control device for a hydrogen fuel logistics vehicle. The integrated three-in-one control device comprises a control panel and a power panel; a steering motor controller, an electric pile air compression motor controller and a brake air compression motor controller are integrated on the control panel; the low-voltage output end of the steering motor controller and the low-voltage output end of the brake air compression motor controller are connected with the first CAN communication network. The second CAN communication network is a vehicle fuelcell network, and the low-voltage output end of the pile air compression motor controller is connected with the second CAN communication network; the high-voltage input end of the steering motor controller, the high-voltage input end of the galvanic pile air compression motor controller and the high-voltage input end of the brake air compression motor controller are all connected with the power board. The power board is provided with an IGBT power element and a relay which are electrically connected with the steering motor, the galvanic pile air compression motor and the brake air compressionmotor respectively. The control device has the beneficial effects that the size of the controller is effectively reduced, and the product cost is reduced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an integrated three-in-one control device for a hydrogen fuel logistics vehicle. Background technique [0002] As hydrogen fuel cell logistics vehicles gradually begin to be applied and produced on a large scale, how to design a system integration solution suitable for hydrogen fuel cell logistics vehicles has become the main research direction of all OEMs and parts factories. [0003] Since the hydrogen fuel cell system of the hydrogen fuel cell logistics vehicle using high-voltage steering motor and air pressure brake needs to carry an air compressor, the hydrogen fuel cell logistics vehicle carries three controllers, which are the stack air compressor motor controller , Brake air compression motor controller and steering motor controller, if these controllers are arranged separately, not only the volume is large, occupying the layout space of the whole vehicle, but...
