Abstract

The invention relates to a multimode starting system of a fuel cell power supply, comprising a controller connected by a line, a starting storage battery, a charger, an electrifying switch K1, a two-way relay K2, a variable voltage power supply, a diode D1, an external starting high voltage interface, an external starting low voltage interface and an external charging interface. By applying the system, multimode charging on the starting storage battery in the fuel cell power supply can be realized, and another storage battery starting system can be externally connected under the condition that the electric quantity of the starting storage battery is not enough to start the fuel cell power system. The system in the invention has the characteristics of low implementation cost, simple structure, and high safety and reliability, and is easy to operate.

Description

A multi-mode start-up system for fuel cell power technical field The present invention relates to the technical field of fuel cells, in particular to the start-up technology of a fuel cell power generation system. Background technique The fuel cell power generation system is divided into two forms: external start and self-start. Among them, the self-starting fuel cell power generation system is disclosed in patents ZL200920203954.7 and ZL200920016349.9, and the starting battery mostly adopts lead-acid battery or lithium battery as the starting battery. As chemical batteries, lead-acid batteries and lithium batteries have the problem of self-discharge during storage. If the self-starting fuel cell power generation system is not used for a long time, the lead-acid battery or lithium battery as the starting battery is likely to cause its own residual power to be too low due to self-discharge, which is not enough to start the fuel cell power generation system and cannot run. ...
