Description
Technical field
The present invention is a kind of blending together (hybrid) electric supply installation and method for managing power supply thereof.
Background technology
In recent years on battery powered research field, except in the past to battery request want can volume little, power-on time for a long time, the adding of environmental consciousness makes that the trend of battery not only wants can volume little, power-on time is of a specified duration, more want to reuse and can not work the mischief to environment, therefore the battery of many emerging kinds also arises at the historic moment, and for example solar cell and fuel cell are exactly wherein a part of.Yet how restricted this class battery is in the use.For example the electric energy of fuel cell produces and need produce electromotive force and supply enough electric currents via inner chemical reaction, thus the electrical parameter of its output (as voltage, electric current, power or the like) to be subjected to the various factors influence of internal oxidation reduction reaction very big.In addition, when fuel cell was exported at high power, it is not good that the chemical energy in the fuel cell converts the efficient of electric energy to, and the time of using for fuel cell has significantly influence.Therefore singly be that to utilize fuel cell be very impracticable on efficient as the power supply source, institute is so that blend together electric supply installation with other power supply source of arranging in pairs or groups to become one, improves original single not good result of usefulness when exporting for high power with fuel cell.

REF, see through an operational amplifier 16 and transmit voltage to one control unit 15.This control unit 15 is sent a control signal 17 to this dc power converter 12 according to the voltage that is transmitted by operational amplifier 16, regulates the output voltage V of this dc power converter 12
OutYet, if the peak power output of fuel cell 11 has been not enough to deal with the demand that dc power converter 12 provides load 14, or during fuel cell 11 own fuel capacity deficiencies (in other words promptly being the capacitance deficiency), the capital makes the output voltage of fuel cell 11 continue to descend, and can't normally use up to fuel cell.In order to prevent such situation, fuel cell 11 must be able to satisfy under the various situations, its peak power output can both exceed the demand of dc power converter 12, in other words must just can make fuel cell 11 reach such demand with higher cost, weight and space, and this can light-weighted demand run in the opposite direction to battery with us.

REFProduce the signal of FEEDBACK CONTROL, adjust the number that 22 pairs of fuel cells 21 of dc power converter draw electric energy, can reach certain effect to the lifting of the energy conversion efficiency of fuel cell 21, also can avoid taking place fuel cell 21 situation that can't normally use takes place.Fuel cell 21 operating periods meeting cause the change of electrode potential because of the variations in temperature of change of the concentration of fuel or battery itself, influence the electric current output of fuel cell 21, but within the specific limits can be via the control of feedback mechanism and secondary cell 23, control dc power converter 22 is drawn the size of electric current, keeps the voltage output of fuel cell 21.Though the difference of the demand power of power output that feedback mechanism and secondary cell 23 can the fuel metering batteries and load 24 within the specific limits, but when secondary cell 23 fills full or secondary cell 23 when having reached discharge cut-off voltage, secondary cell 23 just loses the function of adjusting, more may therefore cause the damage of secondary cell 23.

CONTROLSend in the power supply changeover device 33.Power supply changeover device 33 is a boost type DC power supply changeover device (boost-type DC-DC power converter), be a MAXIM wafer (wafer number MAX 1701) in this example, this wafer constitutes our visible dc power converter 34 with other element again.When secondary cell 36 fills when full, if continuing power outputs, fuel cell 31 gives secondary cell 36, then may cause the damage of secondary cell 36, so U.S. Pat 6590370 provides a protective circuit 35, in order to protection secondary cell 36.Protective circuit 35 is an electric current shunting regulating circuit (shunt voltage regulator); when the voltage of secondary cell 36 has arrived charging cut-ff voltage (the expression secondary cell has filled full); the voltage of fuel cell 31 outputs this moment only has few part can be sent to secondary cell 36, and (secondary cell is not to stop charging filling when satisfying; but with atomic low current charge); all the other all are sent to protective circuit 35, and unnecessary electric energy can convert heat energy to and disappear in protective circuit 35.So just can avoid secondary cell 36 to damage and can improve again the service efficiency of fuel cell 31.Though solved the problem that secondary cell 36 damages in such event, not only wasted the fuel of fuel cell 31 but also more may cause the burden of system's heat management by the method that unnecessary electric energy transferred to thermal energy consumption.On the other hand, if load 37 continues to keep high power requirements, force secondary cell 36 necessary continuous outputs, also may make secondary cell 36 electric weight exhaust, voltage arrives discharge cut-off voltage, and the situation of power supply failure (power failure) takes place.
Though above-mentioned prior art provides the method for managing power supply that blendes together electric supply installation, but still have fuel cell service efficiency situation unclear and waste fuel cell electric energy to take place, therefore how to take into account the service efficiency of fuel cell and secondary cell, making the power management effect of composite set better then is main purpose of the present invention.
