Description

Ultracapacitor charging device
Technical field
The present invention relates to battery charger, be specially ultracapacitor charging device.
Background technology
Ultracapacitor is a kind of Novel energy storage apparatus that eighties of last century grows up the seventies, is again gold electric capacity, farad capacitor.There is not chemical reaction in its thermal energy storage process, only need carry out energy storage by polarized electrolytic matter, therefore this thermal energy storage process is reversible, can carry out the cycle charging up to 100,000 times.The advantages such as the power density of ultracapacitor is 100 times of chemical cell, has extra long life, safe and reliable, environmental protection, non-maintaining, can carry out quick charge to it, only need just can be full of for several seconds to several minutes.Be widely used in now the fields such as various electronic equipment, regenerative resource, electric automobile, input, military weapon.
The charging modes of ultracapacitor mainly contains: the charging of constant current charge, constant voltage charge, invariable power, pulse current charge, constant-current constant-voltage charging.Constant-current constant-voltage charging refers to and first carries out constant current charge, and the voltage at battery two ends constantly rises, and when rising to voltage predetermined value, just carries out constant voltage charge, and this process electric current reduces gradually, when electric current close to 0 time, charging complete.Constant voltage constant current charging can carry out quick, high efficiency charging to ultracapacitor.In-40 DEG C of-70 DEG C of temperature ranges, the performance of ultracapacitor is more stable, and when temperature exceedes this scope, the performance of ultracapacitor is sharply deteriorated.Be necessary so carry out monitoring to temperature in ultracapacitor charge and discharge process.
Existing ultracapacitor charging device is due to fault of construction, and performance is relatively poor, and structure is more complicated, inconvenient operation, particularly can not carry out effective monitoring to temperature.
Summary of the invention
The present invention solves existing ultracapacitor charging device poor-performing, complex structure, inconvenient operation and can not carry out the problems such as effective monitoring to temperature, provides a kind of ultracapacitor charging device.
The present invention adopts following technical scheme to realize: ultracapacitor charging device, comprise casing and internal circuit, described casing is provided with LCD touch screen, casing is also provided with ultracapacitor draw-in groove, the end face of draw-in groove is provided with positive and negative electrode, the bottom surface of draw-in groove is provided with temperature sensor, and the bottom of draw-in groove is provided with cooling fan or circulating cooling water jacket, internal circuit comprises charging circuit and charging control circuit, charging circuit comprises the IGBT inverter, transformer, rectification circuit and the filter circuit that connect successively, two outputs of filter circuit are connected with the positive and negative electrode of draw-in groove end face respectively, and charging circuit also comprises charging voltage sensor and charging current sensor, the IR2235 control chip that charging control circuit comprises dsp chip and is connected with dsp chip, the output of IR2235 control chip is connected with the IGBT control end of the inverter in charging circuit, charging voltage sensor in charging circuit, the temperature sensor of charging current sensor and draw-in groove bottom surface is connected with the input of dsp chip, LCD touch screen on casing is connected with dsp chip, the output of dsp chip is connected with cooling fan or circulating cooling water jacket, and (whether the cooling water circulation namely in the switch of cooling fan or circulating cooling water jacket is controlled by the output of dsp chip.How output as dsp chip finally realizes the operating state of controlled cooling model fan and circulating cooling water jacket, is the known routine techniquess of one of ordinary skill in the art).
Operation principle of the present invention: the ultracapacitor that need charge to be stuck in the draw-in groove on casing and to dock with positive and negative electrode.User arranges the preset voltage V of constant voltage charge by LCD touch screen regwith the electric current I of complete charge offand design temperature T reg.DC source inputs, and through IGBT inverter, obtains alternating current, then charges to super capacitance cell group through transformer and current rectifying and wave filtering circuit.In charging process, constantly the voltage in charging circuit, electric current are monitored by voltage, current sensor, and feed back in dsp chip, voltage, current value and default V that dsp chip will obtain reg, I off, compare, according to the ratio control IR2235 control chip of its difference, the PWM ripple that output duty cycle is different, thus inverter is regulated and controled, control voltage, the electric current in charging circuit, realize the constant-current constant-voltage charging to ultracapacitor.The temperature obtained by temperature sensor compares with preset temperature, when actual temperature is higher than set point, controls refrigerating plant by DSP, realizes the control to supercapacitor temperature.The electric current detected, voltage, temperature value are shown by LCD touch screen simultaneously.As can be seen from the above-mentioned course of work, the software involved by dsp chip is that one of ordinary skill in the art easily realize.
The present invention realizes setting and the Presentation Function of parameter by LCD touch screen, and by voltage sensor, current sensor, temperature sensor is to the voltage of charging circuit, the temperature of electric current and ultracapacitor carries out Real-Time Monitoring, the parameter information detected as feedback signal through DSP process, export the pwm signal of different duty to the voltage in charging circuit, electric current controls, regulated the temperature of ultracapacitor by refrigerating plant simultaneously, achieve the function of the constant current constant voltage charge and discharge control of temperature-controllable, possess functional, structure is simple, man-machine interface is good, the advantage such as easy to operate.
