Abstract

An apparatus and method for controlling the measurement of cell voltage of a fuel cell, the apparatus comprising: terminals connected between serially connected cells of a fuel cell; first resistors connected in series to the terminals; capacitors connected in parallel respectively Between a first resistor to store a voltage; a switch, connected to the first resistor to switch to a closed or open state; a second resistor, connected in series between the lowest cell in the battery and the semiconductor GND to provide a a path along which current flows when reverse voltage is generated in the battery; a diode connected in parallel to the second resistor to provide a path along which current flows when reverse voltage is not generated in the battery; and a controller configured to respond to the battery voltage The measurement or open wire diagnostic mode changes the state of each switch and performs battery voltage measurements and open wire diagnostics.

Description

[0001] Citations for Relevant Applications [0002] This application claims priority to Korean Patent Application No. 10-2018-0172750 filed in the Korean Intellectual Property Office on December 28, 2018, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments of the present disclosure relate to a method of controlling measurement of a cell voltage of a fuel cell and an apparatus for performing the same, and more particularly, to a method in which reverse voltage can be limited in the following manner when reverse voltage is generated in a fuel cell current to prevent burnout of the fuel cell voltage measurement semiconductor attributable to reverse voltage, i.e. allowing reverse current to flow through the fuel cell voltage measurement semiconductor's resistors rather than the pins that control the fuel cell voltage measurement Method and apparatus for performing the same. Background technique [0004] In general, a fuel cell...
