The circuit can be automatically protected when the battery jar is charged, the anode and the cathode are reversely connected, and the short circuit happens to the output end of a charging power supply; and the circuit has the advantages of simplicity, safety, reliability, convenience and practicability, and is easy to popularize.
Description
Technical field:
The utility model relates to field of electric control, a kind of storage battery charging adjunct circuit, and positive-negative polarity connect anti-circuit when anti-storage battery charged.
Background technology:
People charge to storage battery with charger, often because of carelessness wrong positive-negative polarity, damage storage battery and charger, even lead to a disaster;
Summary of the invention:
The utility model purpose at the present situation of existing charger deficiency, provides the simple and reliable anti-positive-negative polarity of storage battery charging of a kind of circuit to connect anti-circuit, and to the storage battery charging, the wrong positive-negative polarity can not damage storage battery and charger, and is convenient, safety.
The present invention is achieved by the following technical solutions:
The anti-positive-negative polarity of a kind of storage battery charging connects anti-circuit, it is characterized in that, and by relay, control circuit, indicator light is formed.The positive pole of charge power supply connects the storage battery positive pole through the normally opened contact of relay; Charge power supply cathode output end one tunnel connects the storage battery positive pole, and another road connects the base stage of control triode Q1 through light-emitting diode D3, resistance R 1; The positive pole of charge power supply input separates through diode D1, after the filtering of capacitor C 1, and series resistor R3, relay coil J1, the collector electrode of connection triode Q1, the emitter of Q1 connects power cathode.
There is not the anti-positive-negative polarity of storage battery charging to connect between the charge power supply and storage battery of common charger of circnit NOT, insert this circuit, the positive pole of charge power supply connects the storage battery positive pole through the normally opened contact of relay, the electrode input end of charge power supply separates through diode D1, after the filtering of capacitor C 1, make the power supply of control circuit.When the positive-negative polarity of the output positive and negative charge of charge power supply and storage battery connect to the time, at this moment charge power supply goes back access failure, the cathode power supply of storage battery is by being connected on the joint of charge power supply cathode output end, light-emitting diode D3, resistance R 1, make the base stage of triode Q1 obtain conducting voltage, if at this moment charge power supply powers up, its power supply is by diode D1, resistance R 3, relay coil J1, to power cathode, because of the base stage of triode Q1 has had the voltage conducting of the conducting that storage battery sends here, relay gets electric and adhesive by triode Q1, output is connected, the charging beginning.
When the output positive and negative charge of charge power supply and the positive-negative polarity of storage battery connect inverse time, light-emitting diode D3 is by obstructed, not luminous, and triode Q1 ends, not adhesive of relay, protection charger and storage battery.If the storage battery that charger connect is in short-circuit condition, perhaps in charging process, the output short circuit, then light-emitting diode D3 does not have electric current to pass through, and triode Q1 ends, and relay is release condition, and the protection charger.
D4 is a light-emitting diode, makes charge power supply and connects indicator light, and D3 connects connecting indicator light for positive and negative poles of battery, it is right that charging output positive and negative terminal and positive and negative poles of battery connect, then D3 is luminous, and light-emitting diode D3 prevents that charge power supply polarity from connecing anti-prompting and interception.Resistance R 3 is appropriate with capacitor C 2 values, and relay is adhesive smoothly when starting, and can keep adhesive with less current again after the startup.After storage battery was full of, storage battery contact and charge power supply all should disconnect.
Beneficial effect: to the storage battery charging, the wrong positive-negative polarity is protected charger and storage battery automatically; Or the short circuit of charge power supply output, then protect charger; Circuit is simple, and is safe and reliable, convenient and practical, easily promotes.
Description of drawings:
Fig. 1 is the utility model pie graph.
Fig. 2 is the utility model circuit diagram.
Among Fig. 2,1. be the charge power supply input, 2. relay, 3. the charge power supply cathode output end promptly connects the storage battery positive terminal, 4. light-emitting diode D3,5. 6. control circuit is storage battery.Wherein: D1-2 is diode IN4007, and D3, D4 are that light-emitting diode is made indicator light, and Q is NPN type triode C2383, and C1-2 is an electrochemical capacitor, and R1-3 is a resistance, and J1 is a relay.
Embodiment:
The anti-positive-negative polarity of a kind of storage battery charging connects anti-circuit, it is characterized in that, as shown in Figure 2: by relay, control circuit, indicator light becomes; D1-2 is diode IN4007, and D3 connects indicator light for positive and negative poles of battery, and D4 is a charge power supply control circuit indicator light, and Q1 is NPN type triode C2383, and C1-2 is an electrochemical capacitor, and R1-3 is a resistance; According to the charge power requirement, selective relay J1.
The positive pole of charge power supply input connects the storage battery positive pole through the normally opened contact of relay, and the cathode power supply of storage battery is by being connected on the joint of charge power supply cathode output end, light-emitting diode D3, and resistance R 1 makes the base stage of triode Q1 obtain conducting voltage; When charge power supply powered up, its power supply was by diode D1, resistance R 3, relay coil J1 to power cathode, has had the voltage conducting of the conducting that storage battery sends here by triode Q1 because of the base stage of triode Q1, relay gets electric and adhesive, and output is connected, the charging beginning.
When the output positive and negative charge of charge power supply and the positive-negative polarity of storage battery connect inverse time, light-emitting diode D3 is by obstructed, not luminous, and triode Q1 ends, not adhesive of relay, protection charger and storage battery.If the storage battery that charger connect is in short-circuit condition, perhaps in charging process, the output short circuit, then light-emitting diode D3 does not have electric current to pass through, and triode Q1 ends, and relay is release condition, and the protection charger.After storage battery was full of, storage battery contact and charge power supply all should disconnect.
The anti-positive-negative polarity of storage battery charging connects anti-circuit, anti-wrong positive-negative polarity, anti-power output end short circuit, protection automatically; Circuit is simple, and is safe and reliable, convenient and practical, easily promotes.
