Detection system for diagnosing voltage of fuel cell

Abstract

The invention discloses a detection system for diagnosing voltage of a fuel cell. The detection system is characterized by comprising a first battery pack, a second battery pack, a battery pack information acquisition module, a monitoring microcontroller module, a battery pack switching module, a voice module, an LED (Light-emitting Diode) indicator lamp, a wireless communication module and a mobile terminal, wherein the first battery pack, the second battery pack, the battery pack information acquisition module, the battery pack switching module, the voice module and the LED indicator lamp are separately connected with the monitoring microcontroller module, the battery pack information acquisition module is mounted on the first battery pack and the second battery pack, and the monitoringmicrocontroller module is in communication with the mobile terminal through the wireless communication module. According to the detection system, through detecting whether the cell is subjected to short circuiting and overheating a supercapacitor or power cell is overcharged or not, the self-detection capability of the cell is improved, and the coefficient of safety of use is increased.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a detection system for diagnosing the voltage of a fuel cell. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure.
