摘要

A charging network is described having a series pass element for delivering charging current to a battery, means for sensing the state of charge of the battery, and control circuitry for regulating battery charging. A non-linear voltage reference element operatively associated with the control circuitry enables the battery to be charged to a predetermined relatively high voltage cut-off level at which time positive latch-out of charging occurs. Charging is reinitiated only after the battery voltage level has dropped to a predetermined level below the initial charge cut-off level. This hysteresis effect (loop width) may be selectively controlled.
