Abstract: |
A device for monitoring single plate voltage of vehicle fuel cell is featured as connecting input end of optical couple gating communication circuit to each single plate of fuel cell in sequence, connecting output end to isolation circuit input end, inputting signal to monolithic computer through absolute value circuit after isolation treatment, controlling four I / O pin signals by said computer and using hardware interlocking circuit to ensure uniqueness of gating channel, carrying out communication with external main controller by monolithic computer through CAN communication circuit. |
