For battery voltage tracking for optimum charging voltage.
The service life of batteries is specified at a temperature of 20°C. Temperatures above 20°C on the batteries lead to a drastic reduction in battery life.
The temperature sensor, which can be connected to the AKKUTEC at IO-1 terminals 1 and 2, automatically adjusts the charging voltage according to the ambient temperature. An overtemperature at the batteries is displayed and reported.
