Description

Technical Field

[0001] This utility model relates to the field of high-voltage insulation testing technology for battery stacks, and in particular to a fully automated high-voltage insulation testing device for fuel cell stacks. Background Technology

[0002] A fuel cell stack is an integrated system composed of multiple fuel cell units. It directly converts the chemical energy of fuel (such as hydrogen) into electrical energy through electrochemical reactions. It is characterized by high efficiency, cleanliness, and modularity, and is widely used in transportation, power generation and other fields.

[0003] Battery stacks operate under high voltage (such as hundreds of volts to thousands of volts). If the insulation fails, the casing or connecting parts may become live, causing electric shock to the operator. Insulation breakdown may lead to short circuit, causing local overheating or even thermal runaway (such as thermal runaway in lithium batteries), ultimately leading to fire or explosion. Therefore, it is necessary to test them before they leave the factory.

[0004] Existing testing equipment relies heavily on manual operation, has a low degree of automation, and has high labor costs. In case of accidents, it can easily lead to worker injuries and loss of life and property.

[0005] Therefore, this application provides a fully automated high-voltage insulation testing device for fuel cell stacks to overcome the deficiencies of the prior art. Utility Model Content
