Abstract
The monitor is a circuit including an integrator for storing a state-of-charge measurement and a charge signal channel and a separate discharge signal channel both arranged for connection to receive a battery terminal voltage signal. The charge signal channel is operable in response to a battery terminal voltage signal above a charge threshold function voltage to produce a charge output signal to change the integrated measurement in the integrator in a first direction to indicate an increased charge. The discharge signal channel is operable in response to a battery terminal voltage signal below a discharge threshold function voltage to produce a discharge output signal to change the integrated measurement in the integrator in a second direction to indicate a decreased charge. Both the charge and discharge threshold function voltages are functions of the stored integrator state-of-charge measurement.
