Title:
エネルギ蓄積器のセルスタックのセルの個別セル電圧の測定のための装置及び方法
Document Type and Number:
Japanese Patent JP4171049
Kind Code:
B2
Abstract:
In parallel with each cell, two diodes are connected in series. The connections of a switch (UM) are connected via respective capacitors to the connection points of the diodes associated with each cell. A reference circuit (REF) comprises two series-connected diodes. A differential amplifier (Diff1) has is non-inverting input connected to the output of the switch, and the inverting input connected to the connection point of the series-connected diodes of the reference circuit. A rectifier (GLR) and controlled AC source (I1) are also provided. An independent claim is included for a method of operating the measuring device.
