4.4 Impact of temperature on cell performance and available
capacity
When sizing and choosing a battery the variations in ambient temperature and their influence
on the cell performance have to be taken into consideration. Low ambient temperature
conditions reduce the cell performance. However, operations with higher temperatures are
similar to those at normal temperatures. Lomain next generation batteries offer improved
values especially at high temperature applications. The effects of low-temperature operation
increase with higher rates of discharge.
The values, which have to be taken into account, can be found in the following graph.
Lomain next generation batteries passed a long term temperature test at co50°C
surrounding temperature followed by a discharge test out of the float mode as indicated on
the chart below.
