Abstract

The invention provides a fuel cell power system for a forklift. The fuel cell power system for the forklift comprises a casing (90), a fuel cell system (100) arranged in the casing (90), a direct current to direct current (DCDC) conversion unit (2), a contactor (3), an energy storing device (4) and a controller (7). The fuel cell power system for the forklift further comprises a power output end (5) arranged outside the casing (90) and an operation control unit (6) arranged in the casing (90), the contactor (3) is a normally open type large current contactor, the DCDC conversion unit (2) comprises a DCDC converter (21) and a high power diode (22), and the DCDC converter (21) and the high power diode (22) are connected. The fuel cell power system for the forklift is compact in structure, can be installed, overhauled and maintained conveniently, can be used for placing the energy storing device with higher capacity, enables the energy storing device to be in a long-range charge-discharge state, and prolongs service life of the energy storing device and the time for being shelved.

Description

technical field [0001] The invention relates to a fuel cell system, in particular to a fuel cell power supply system for a forklift. Background technique [0002] When designing a fuel cell system for a forklift, in order to directly replace the existing lead-acid battery to avoid the modification of the forklift, all the components had to be concentrated in a rectangular cavity. The fuel cell system for forklifts needs to include controllers, energy storage devices, DCDC converters, contactors, fuel cell systems, hydrogen filling valves, hydrogen bottles, hydrogen supply systems, etc. To achieve the same weight as the lead-acid battery, the system also needs to place a counterweight. The components required for the entire system are integrated in a small space, resulting in no space between components. This will cause installation and disassembly to be very troublesome. Even when disassembling parts, other parts have to be disassembled. [0003] There are many weak poin...
