Determining battery temperature, especially vehicle battery acid temperature, involves estimating battery temperature from measurements correlated with battery temperature values at defined times

摘要

The method involves measuring a temperature correlated with the battery temperature using a sensor (16,17) and estimating the battery temperature from the measurement values at definable times. The further temperature is the temperature of a device arranged in the immediate vicinity of the battery (11) and the operating state of the device is taken into account.
