Abstract
The utility model relates to an automatic charger that belongs to the technical field of electronics. An accumulator Vc outputs direct current voltage that is compared with a set magnitude of voltage, and deviation signals are obtained through an electrical bridge, while an amplifying circuit amplifies the deviation signals. A switching circuit of two position control is applied to execute deviation signals and control a relay to work or not, and the relay controls the accumulator to be charged or not. The automatic charger can keep a standby power under a set voltage frequently without manual control of charge.
Description
The utility model belongs to electronic technology field, relates to a kind of automatic electrical energy storage device.
General using electricity system, particularly weak electricity system are if want to remain uninterrupted electricity consumption, except that normal mains supply, also dispose storage battery as stand-by power supply, storage battery does not enter operating state generally speaking, only when grid power blackout, storage battery is just to using electricity system output electric energy, and no matter whether storage battery use, and all should regularly charge, also then, storage battery is discharge automatically, can't power to using electricity system.
The purpose of this utility model provides a kind of device that just charges automatically according to battery tension.
The utility model know-why is as follows:
By storage battery V
CWhether output dc voltage and setting voltage value relatively obtain deviation signal by electric bridge, through amplifying circuit deviation signal are amplified, and by work by-pass cock circuit, carry out deviation signal, and whether control relay moves, charged by relay control storage battery.
