Abstract
The utility model discloses an intelligent charger which comprises a transformer, a contactor, a rectifier, a fuse and a control board. The transformer is provided with an auxiliary magnetic circuit, electric energy of the control board is provided by a battery, input of the charger can be connected to a power grid all the time without manual power cut, voltage and current are intelligently controlled by embedded software full-automatically. The problems that like products fail to effectively control current, the transformer is small in inductive resistance, and voltage of a storage battery cannot be automatically controlled are solved by the use of the intelligent charger.
Description
Technical field
The utility model relates to a kind of charger, relates in particular to a kind of intelligent charging machine.
Background technology
Domestic current charger technology is ripe gradually, but more or less all can there be following problem: first, can not effectively control electric current in the charging process, the induction reactance of transformer is less, in the starting stage of charging, i.e. in the lower stage of cell voltage, electric current can be very large, can affect battery life on the one hand, can make on the other hand transformer temperature too high; The second, can not automatically control and analyze battery tension, be full of and can not end charging behind the electricity; The 3rd, current waveform does not reach spike, and battery electrolyte mixes inhomogeneous, and the substrate in the battery can not devulcanization.Therefore, avoid simultaneously occurring above three defectives, must come Limited Current with another kind of impedance, also will choose suitable rectifier stack and capacitance values, and control circuit board is done some improvement.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of degree of intelligence high, effectively control the charger of charging current, satisfy the purpose that improves charging process fail safe and service lifetime of accumulator.
For finishing above-mentioned purpose, the technical solution adopted in the utility model is: charger adopts magnetic circuit-divided transformer, namely laterally adds a slice silicon steel sheet in the three-phase transformer three-limb core, to increase leakage field, increase inductance, the large I of transformer output voltage and leakage field is obtained by the Ansoft simulation software; The electric energy of control circuit board is provided by battery, and the input of charger can be connected on the electrical network always, need not artificial cut-out, and whole charging process voltage and current adopts the embedded software Based Intelligent Control, automatically finishes; Choose suitable rectifier stack and capacitance values, can make current waveform produce spike, add suitable control strategy, battery electrolyte is mixed, and can make the substrate devulcanization in the battery.
The beneficial effects of the utility model: charger has overcurrent protection, overvoltage protection, under voltage protection, short-circuit protection, open-phase protection has very strong voltage adaptation ability, by efficient charging, make charge capacity the most reasonable, prolonging service life of battery is compared with high-frequency charger, and the life-span is long, reliable operation, failure rate is low; Adopt LCDs, detailed charger, storage battery information display function are arranged, interface quality is high, and LCD literal clear display is diagnosed and safeguarded that fault is timely, fully automatic operation.
Description of drawings
Below in conjunction with embodiment the present invention is described in detail.
Fig. 1 is the structure chart of intelligent charging machine;
Among the figure: 1, fuse, 2, control board, 3, transformer, 4, contactor, 5, rectifier bridge.
Embodiment
As shown in Figure 1, intelligent charging machine comprises 1, fuse, 2, control board, 3, transformer, 4, contactor, 5, rectifier bridge; Transformer 3 adopts magnetic circuit-divided transformer, namely laterally adds a slice silicon steel sheet in the three-phase transformer three-limb core, to increase leakage field, increases inductance, and the large I of transformer output voltage and leakage field is obtained by the Ansoft simulation software.
The electric energy of control board 2 is provided by battery, and the input of charger can be connected on the electrical network always, need not artificial cut-out.When needing charging, directly battery is connected plug.Charging process is automatically finished.Charge after the beginning, computer system monitors charging process, if charge 10 minutes, battery cell voltage is lower than 1.5V, or the 1 hour battery tension that charges is lower than 2.0V, charging meeting interruption, LED indicator light indication storage battery mistake.Reach battery rating and do not reach the venting point voltage if be filled with electric weight, charger can be given the indication that makes mistake.Charging process continues, but calculates according to battery rating.After charging arrived 80%, the 80%LED indicator light can be lighted very soon.For accumulators provides the optimal charge electric weight, circuit board can be adjusted charging coefficient and charging interval automatically according to depth of discharge.When arriving the venting point, 96% electric weight has been filled with storage battery.The residue charge capacity can calculate automatically according to the charging coefficient of selecting.The shortest charging interval is 60 minutes.The charger control system can monitor charging process, calculates total charge capacity, and charging process is stopped in good time.After storage battery was full of electricity fully, charger can stop charging automatically.100% indicator light is lighted, and LCD shows " charge end ". and after charging finished, charger can increase the charging of 3 multiple pulses in addition, and electrolyte is well mixed.After charging finished, if storage battery still keeps being connected with charger, charger can provide maintenance charging and equalizing charge by accumulators.
Choose suitable rectifier stack and capacitance values, can make current waveform produce spike, add suitable control strategy, for example charging normal the end, adopt the pulse current charge of high low current, battery electrolyte is mixed, and can make the substrate devulcanization in the battery.
