Abstract
The invention relates to a storage battery voltage detecting and charging circuit for a solar street light, which is formed by connecting a storage battery, a metal oxide semiconductor (MOS) tube, two triodes, four resisters and two capacitors to achieve the effect of detecting storage battery voltage and charging the storage battery with solar power. The storage battery voltage detecting and charging circuit has the advantages that: a solar indicator lamp is switched on when a battery is charged by a photovoltaic panel, while the solar indicator lamp is switched off when the battery is not charged; and a storage battery indicator lamp twinkles when the storage battery voltage is too low, while the storage battery indicator lamp is switched on normally when the voltage is increased to a certain voltage by charging. The storage battery voltage detecting and charging circuit achieves the effects of functional automation and energy-saving and environment-protection.
