Abstract
The utility model discloses a control device for low-voltage power-off protection, which is composed of a power input line, a power output line, a resistor, a silicon controlled rectifier, a power switch, a fuse and a storage battery. The control device is characterized in that: one end of the resistor is connected with a collecting electrode of the silicon controlled rectifier, and the other end of the resistor is connected with a trigger end of the silicon controlled rectifier; a line is led out of the collecting electrode of the silicon controlled rectifier to be used as the power input line, and a line is led out of a discharge electrode of the silicon controlled rectifier to be used as the power output line; the power output line is connected with the power switch; the power input line is connected with the fuse; and the other end of the fuse is connected with the storage battery. When the rectifier can not charge or can slightly charge, the discharging electric energy of the storage battery is greater than the charging electric energy of the storage battery, and the voltage of the storage battery drops gradually; and when the voltage of the storage battery is lower than 10V, the trigger voltage of the silicon controlled rectifier can not reach the working voltage of the silicon controlled rectifier, so that the silicon controlled rectifier is cut off and the electric energy of the storage battery can not pass, thereby realizing the function of automatically closing the output of the storage battery when the voltage of the storage battery is lower than 10V.
Description
Technical field
The present invention relates to a kind of vehicle battery apparatus for protecting power supply, is a kind of low-voltage power-off protection control device that is used for concretely.
Background technology
Storage battery is as the storage container of car load power supply supply, and the electric energy of storage battery needs replenish by rectifier, maybe can not charge and will cause battery overdischarge when rectifier charging is less than normal, and battery overdischarge will have a strong impact on the useful life of storage battery.
Summary of the invention
The object of the present invention is to provide a kind of low-voltage power-off protection control device that is used for, make the useful life that under the normal operating position that guarantees storage battery, also can effectively prolong storage battery.
The present invention realizes with following technical scheme: this a kind of low-voltage power-off protection control device that is used for is made up of power input line, power supply output line, resistor, controllable silicon, mains switch, fuse, storage battery.It is characterized in that: resistor one end is connected with the silicon controlled collector electrode; The other end is connected with the silicon controlled trigger end; The silicon controlled collector electrode is drawn a line as power input line, and the silicon controlled discharge electrode is drawn a line as power supply output line, and power supply output line is connected with mains switch; Power input line is connected with fuse, and the fuse other end is connected with storage battery.When rectifier can not charge or charge when less than normal; The discharge electric energy of storage battery is greater than rechargeable electrical energy, and the voltage of storage battery descends gradually, when the voltage of storage battery is lower than 10V; The silicon controlled trigger voltage does not reach the silicon controlled operating voltage; Controllable silicon ends, and the electric energy of storage battery can not pass through, and has realized closing automatically when battery tension is lower than 10V the function of storage battery output.
The invention has the beneficial effects as follows: effectively prevent battery overdischarge, prolong the useful life of storage battery.
