摘要： The apparatus includes a battery charger having a pair of input terminals adapted to be connected to an AC source of potential and a pair of output terminals adapted to be connected to the respective terminals of a battery. A rectifier converts the AC energy to DC. A series connected SCR is operable to connect the source with the battery when the battery potential is below a predetermined value. A reactance is provided to lower the source potential and to obtain substantially constant current for charging purposes. A shunt connected SCR is provided to limit the potential applied to the series SCR when the battery is charged to protect the battery and the series connected SCR. The apparatus further includes a discharger which is operable to disconnect a load from the battery when the battery potential drops to a preselected value, thereby to protect the battery from completely discharging.
