Temperature sense
Temperature Sense uses battery temperature data that is accurately measured directly at a battery terminal or on the battery body and provides it to the charger, the charger then uses this temperature data to dynamically compensate the charge voltage (decrease or increase) according to the specified temperature coefficient (X mV/°C).
The optimal charge voltage of a lead acid based battery varies inversely with battery temperature with the nominal charge voltage specified at 25°C; automatic temperature-based charge voltage compensation avoids the need for manual charge voltage setting adjustments in hot or cold environments.
For lithium batteries the optimal charge voltage remains constant under all normal operating temperatures, however lithium batteries can be permanently damaged if charged in cold conditions; in this case the temperature sense data can be used to automatically disable charging in cold conditions (typically <5°C).
