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 %.
