Abstract
The utility model relates to a charger for an automobile storage battery. The secondary winding of the transformer E is provided with a voltage adjustment joint B. An output terminal is connected with a rectifying diode D< 1 > and an ammeter 1 in series. The output terminal is also connected an ammeter 2 in parallel. The input terminal of the transformer is connected with a current indication part in parallel, and the current indication part is composed of a resistor R, a light emitting diode D< 3 > and a diode D< 2 >. The utility model has the advantages of small volume and light weight and can be carried in an automobile. The charger for an automobile storage battery can be used after being switched on 220-volt alternating current. The charger for an automobile storage battery can also be charged in an automobile without needing to unload the battery. An automobile can be started without breaking power source. Starting current and starting torque can be enlarges and charging time is shorten so that charging efficiency is improved.
Description
The utility model relates to a kind of charger, particularly is suitable for the charger of automobile storage battery.
Because of automobile Fraquent start, storage period are long, storage battery is of low quality or reduce because of reasons such as generator failure all can cause the voltage of storage battery, make automobile be difficult to start and maybe can not start.The automobile storage battery charger that present driver uses is to adopt the charging of full-wave rectification adjustment type, and the volume of this charger is bigger, and price is higher, operating performance is loaded down with trivial details, often want the manual adjustments secondary voltage,, increased management workload to obtain more stable charging current.Another shortcoming of this class charger be when charging current little when a certain numerical value, charging effect then can reduce greatly.Used charger needs storage battery is uncarted just and can be carried out when charging, wastes time and energy, and labour intensity is bigger.
The purpose of this utility model is exactly in order to overcome said deficiency in the above-mentioned background technology, propose a kind of simple in structure, in light weight, charging current stable, easy and simple to handle, both can carry the automobile storage battery charger that can charge onboard again with car.
The technical solution that realizes above-mentioned purpose is such: be provided with a power transformer in the enclosure, be in series with rectifier diode and ammeter on the secondary coil of this transformer, have a voltage on the secondary coil and adjust joint.Be in series with switch and insurance on the primary coil of transformer, resistance and light-emitting diode and diode are connected in parallel on the input of primary coil.Adjust the secondary coil output voltmeter in parallel that joint is drawn by voltage.
Fig. 1: circuit theory diagrams of the present utility model.
Fig. 2: profile schematic diagram of the present utility model.
As shown in Figure 1 and Figure 2, have a power transformer E in the shell 3, the secondary coil of this transformer E is provided with a voltage and adjusts joint B.Series connection one rectifier diode D on the secondary coil output of drawing by voltage adjustment joint B
1With ammeter 1, a voltmeter 2 in parallel on this output.On the primary coil of transformer E, be in series with K switch and insurance A, also parallel resistance R, light-emitting diode D on two inputs
3With diode D
2The power supply indicating section that constitutes.
The operation principle of this charger: give 220 volts of alternating currents of primary coil input of transformer E, after the transformer transformation, obtain required output voltage, again through diode D
1Halfwave rectifier obtains pulsed dc voltage, is connected on the storage battery to be filled and can charges by positive-negative polarity with the output that is made of voltage adjustment joint B.The voltage of charger is by voltmeter 2 indications.It is the preceding calibration voltage contact that dispatches from the factory that voltage is adjusted joint B.
Use this charger also not need storage battery is uncarted, and this charger is put on the car, it is promptly chargeable to be communicated with 220 volts of AC power, and the charging formality is simplified greatly.When being charged to a certain degree, deenergization just can directly not start up the car.Because this charger has equaled on original storage battery in parallel again storage battery has increased power resources, has strengthened starting current and starting torque, has shortened the charging interval, has improved charge efficiency.Because this charger volume is less, it can also be fixedly mounted on a certain locus on the automobile, for the operation of charging is provided convenience greatly.
The utility model has overcome existing deficiency in the background technology, simple in structure, volume is little, in light weight, can carry with car, make full use of the current impulse performance that halfwave rectifier produces, the storage battery of mains voltage variations amplitude big (as the high and low peak of the electricity consumption phase) and different power shortage degree has been improved the relative stability of charging current greatly, even hour also do not influence charge efficiency in charging current.Can charge onboard simultaneously, add great start-up current and starting torque, shorten the charging interval.
