Along with the development of society, electric motor car etc. other need battery to provide the utility use of power more and more universal, and their common feature is to rely on battery that electric power and power are provided.In use, we often use daytime, the charging in night.At present, all there is a common defective in the charger that generally adopts on the market, can't grasp the charging interval, causes undercharge or overcharges.After this type of charger is full of electricity to battery, if in time do not pull out charging plug, produce the drawback of following three aspects: 1) cause fire incident easily.Charger is full of electric continued work; Because mass defect or aging, the long-time electric capacity of crossing is prone to heating, the initiation fire in evening that is being difficult for discovering like the electric elements of the inside; Caused immeasurable loss for the people's the security of the lives and property, this type of accident is appeared in the newspapers repeatly.2) waste power supply.Battery is full of the input and output side power supply that in time breaks of failing behind the electricity, and charger continues with the trickle form to have unnecessary electrical source consumption virtually to battery charge.3) shorten battery life.At present, electric motor car etc. generally adopt the lead-acid battery group, and for a long time charging causes and overcharges, and makes battery heating, bulge, dehydration etc. occur, finally cause battery to shorten useful life.Above drawback is that the establishment safety, the economic energy-conservation society that are advocated with country are contrary.

The utility model content

The utility model provides a kind of electronic control circuit in order to overcome the deficiency of prior art, realizes the break complete automatically outage safe energy saving device of charger of energy-saving safe of charger input and output side of automatic time delay.

The technical scheme that the utility model solves above technical problem is:

The complete automatically outage safe energy saving device of charger is made up of self-lock switch, delay control circuit and charger.
