5.19 Measurements of cell voltages or battery voltages shall be made using a single pole resistive-capacitive low pass filter with a –3 dB roll off frequency of 5 kH±0,5 kHz. To determine if the upper limit charging voltage has been exceeded, the peak value of the filtered voltage shall be measured with a tolerance of ±1 %.9 a$ V( N) ? U4 |5 H6 U m2 `

When measuring cell voltages or battery voltages, the peak value of any superimposed ripple exceeding 10 % of the average value shall be included. Transient voltages are ignored, such as a temporary increase of voltage, for example, after the battery is removed from the charging
