Battery state of charge indicator |
摘要 |
A state-of-charge indicator system monitors the battery current and voltage during operation of a lift truck. Selected current and voltage samples are used to calculate the internal battery resistance and this is employed to calculate a "dynamic" battery voltage. This dynamic battery voltage is used as input to a stored look-up table which provides a battery state-of-charge value.
