Integrated FCU system for fuel cell car

Abstract

The invention discloses an integrated FCU system for a fuel cell car, and relates to the technical field of fuel cell cars. The integrated FCU system specifically comprises a control board and a powerboard, the control board comprises an FCU module, a boost DCDC module, an HCU module and a thermal management system module, the control board is electrically connected with a monitoring and circuitunit through wires, the power board is connected with the monitoring and circuit unit through wires, the power board comprises an IGBT power component and a water pump relay, and two sets of wires ofthe IGBT power component are connected with a throttle valve and a hydrogen cylinder valve in an outputting mode correspondingly. According to the integrated FCU system for the fuel cell car, a four-in-one control system integrating a fuel cell FCU, a boost DCDC, a hydrogen supplying system HCU and a thermal management system is achieved, a power domain controller is highly integrated, thus wiringharness loops are effectively reduced, the contribution rate for the lightweight of wire harnesses is very high, ECU parts of the whole car are also reduced, the production, design and management costs of a power system are lowered, and the integrated FCU system can be applied to hydrogen fuel cell cars.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicles, in particular to an integrated FCU system for fuel cell vehicles. Background technique [0002] Fuel cell vehicles are also electric vehicles, except that the "battery" is a hydrogen-oxygen hybrid fuel cell. Compared with ordinary chemical batteries, fuel cells can supplement fuel, usually hydrogen. The performance is directly related, and the controller is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the vehicle motor. [0003] With the development of fuel cell vehicles and the wide application of network technology in automobiles, as the requirements of automobiles for lightweight, the electrical architecture continues to evolve and develop, and a high degree of integration is bound to become a trend. [0004] The existing fuel cell vehicle control system has insufficient integration, incomplete functi...

AI Technical Summary

Problems solved by technology

[0004] The existing fuel cell vehicle control system has insufficient integration, incomplete functions, intricate wiring harness circuits, relatively low light weight, more and more complex ECU parts in the vehicle, and high cost of production design and management of the power system.
