Abstract

The invention discloses a fuel cell forklift hybrid power controlling system with the function of online monitoring, belonging to the technology of control of the fuel cell forklift. As the fuel cells and lithium cells of the existing fuel cell forklifts have difficulty in playing the best performances, the system provided by the invention uses the structural form where three energy sources of a fuel cell, an auxiliary lithium cell and a super capacitor are configured, uses the fuzzy control to implement energy management and uses the wireless transportation technology such as an embedded system technology, a GPS (global positioning system) technology, a CAN (controller area network) bus management technology and a CDMA (code division multiple access) technology to control and adjust the working performances of the fuel cell and the lithium cell, so as to achieve the best performances of the fuel cell and the lithium cell. The system provided by the invention has the functions of controlling the performances of the fuel cell, managing the energy output, managing the energy of the lithium cell, managing the outputs of multiple energies and wirelessly monitoring the running state of the fuel cell forklift. The system provided by the invention completely solves the problem that the original domestic hybrid power causes pollution.

Description

technical field [0001] The invention belongs to the control technology of a fuel cell forklift, in particular to a fuel cell forklift hybrid power control system with an online monitoring function. Background technique [0002] For existing fuel cell forklifts, it is difficult for fuel cells and lithium batteries to exert their best performance, and it is difficult to automatically recycle system energy, resulting in waste. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defects of existing fuel cell forklifts that the fuel cells and lithium batteries are difficult to exert their best performance, and provide a fuel cell forklift hybrid control system with online monitoring function. [0004] In order to achieve the above object, the fuel cell forklift hybrid control system with online monitoring function of the present invention includes: [0005] vehicle controller; [00...
