Question:
Due to pulse charging (e.g. 2 seconds “in” and 6 seconds “out”) used in many cases, the following
question has arisen. If the mains falls for more than, e.g. 10 minutes, a continuous charging period of
about 20 h will start. During this 20 h period the temperature in the battery compartment may rise to about
10°C higher than during the pulse charging (near 50°C). Shall the temperature during the pulse charging
be regarded as the continuous ambient temperature?
6 p! p9 c4 \# PDecision:
" G0 O( D! J" R% hThe Secretary informed that the Lumex ELP had considered this item at its meeting and confirmed that
the maximum temperature limit of 50°C is applied for the continuous overcharge period only.
