Embodiment
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention easy to understand, with reference to Embodiment, the present invention is further explained.
Referring to Fig. 1~Fig. 5, a kind of solar energy hybrid-driven miniature electric vapour with string type MPPT of the present invention Car, including electric power supply control system.Electric power supply control system includes solar energy bimodulus power supply (solar battery group and storage battery), string formation Formula MPPT controller, energy-storage system, accessory power supply, motor controller, controller power source and motor.Solar battery group and Storage battery is electrically connected with MPPT controller, and MPPT controller is connected by energy-storage system and accessory power supply with motor controller. Controller power source is connected with motor controller, and motor controller is connected with motor.
Solar array is the energy conversion elements in whole system, it according to conditions such as light intensity and temperature, with The external output power of certain output characteristics, there is provided the source of energy.Meanwhile MPPT controller can also fill energy-storage system Electric control, limits its charging current and voltage.Motor controller is used for drive motor and control motor speed torque Deng, while play the role of being controlled energy storage system discharges.
Can be in the maximum functional point of input terminal real-time tracing solar battery group, defeated using string type MPPT controller Go out side controller to be converted by buck according to external circuit situation, make to realize that operating point matches between multimode, so as to fulfill The at utmost output of solar battery array power, then this compound unit is subjected to series and parallel and is connect, it is possible to form a height The photovoltaic power generation array of efficiency.Wherein outside using string type MPPT controller, also match somebody with somebody for each solar cell module A standby miniature DC/DC power converter, to change output characteristics, makes it always work on maximum power point.This sun Energy automobile is than the transformation efficiency higher to luminous energy of general solar telephone, and output characteristics stabilization, cruising ability is stronger, charging side Formula is various, reduces the dependence to weather, and small, and urban transportation is further alleviated in the case where saving energy consumption The situation of congestion.
MPPT controller includes four kinds of operating modes, is respectively bypass mode (STB), direct mode operation (PM), boost mode (Boost) and decompression mode (Buck).In initial phase, STB patterns are initially entered, solar module is equivalent to open circuit shape State, wait for a period of time t in such a modeTSBAttempt to enter operating mode afterwards.Start to follow the trail of MPP, tracking detects output after stablizing Performance number Pmmp, judge whether to exceed set power threshold value PstartminIt is if ineligible, then it represents that illumination it is too weak or Person's component operation fails, then reenters STB patterns.
When starting to work from original state, switching of the STB patterns to Buck patterns is carried out first.Each solar battery group Part is connected with a miniature DC/DC power converter respectively, by controlling miniature DC/DC power converters, makes input side voltage VinProgressively reduce since open-circuit voltage values, input side power increases therewith, and the operating point of system is drawn close to MPP.With input Side voltage VinReduce, outlet side voltage VoutIt is stepped up, if voltage V is surveyed in inputinWith outlet side voltage VoutWhen equal, it is System is still not up to MPP points, then carries out the switching from Buck patterns to Boost patterns, further reduces input voltage and increases at the same time Input power, until reaching MPP points.When system reaches MPP points, if input voltage VmppWith output voltage VoutMeet | Vout- Vmpp| ＜ 0.02VmppRelation when, illustrate that the control effect of DC/DC at this time is very little, system can be directly by solar-electricity Pond component is connected with output terminal, can reduce loss on the contrary, improve efficiency.At this time, system will actively be transferred to PM patterns.
When system steady operation, if there is one of two things, MPPT processes will be restarted：(1) system is steady Surely the time to work or the time in the work of PM patterns have exceeded the time of setting.When steady operation of uniting is sufficiently long Between, or in PM patterns worked more than the regular hour.These time intervals can be set, and main purpose is to keep away Exempt from illumination or load it is slowly varying and make system deviate maximum power point.(2) the output power change △ P of system, which have exceeded, sets Definite value △ Pset.I.e. the output power of system changes more than a threshold value △ P.The limit value can be set, main purpose be in order to Adapt to the unexpected or quick change of illumination or load and cause the deviation of system best operating point.Wherein △ PsetIt is to preset One value, for the output power changing value △ P of system contrast.
The main circuit of MPPT controller includes first switch pipe Q1, second switch pipe Q2, the 3rd switching tube Q3, the 4th switch Pipe Q4, the 5th switching tube Q5, the 6th switching tube Q6 and inductance L.The drain electrode of first switch pipe Q1 is connected with the cathode of input terminal, the The source electrode of one switching tube Q1 is connected with the drain electrode of second switch pipe Q2 and one end of inductance L respectively.The source of second switch pipe Q2 Pole is connected with the anode of input terminal, and the drain electrode of the 3rd switching tube Q3 is connected with the cathode of output terminal.The source electrode of 3rd switching tube Q3 The other end of drain electrode and inductance L with the 4th switching tube Q4 is connected.The source electrode of 4th switching tube Q4 and the anode phase of output terminal Even；The source electrode of 5th switching tube Q5 is connected with the drain electrode of the 6th switching tube Q6.The drain electrode of 5th switching tube Q5 and input terminal are just Extremely it is connected, the source electrode of the 6th switching tube Q6 is connected with the cathode of output terminal.
MPPT block coupled in series models：The system of N number of MPPT block coupled in series, the illumination condition suffered by each module are respectively S1、S2.......SN；Temperature conditionss are respectively T1、T2......TN；Output constant power Pm1、Pm2......PmN.The system can be seen Make the constant power source under the external conditions such as certain illumination, temperature, because operating point self-coordinating MPPT functions can ensure too Positive energy battery pack is always in maximum output power.
The main circuit drawing of the controller of MPPT is exactly a fairly simple DC/DC circuit, this circuit includes four kinds Operating mode：Including bypassing, leading directly to, boosting (Boost), being depressured four kinds of operating modes such as (Buck), cutting between operating mode The control flow that change of current journey may be referred to controller understands.The purpose of this circuit is exactly maximum by the output of some control means Power.The model can be regarded as the constant power source under the external conditions such as certain illumination, temperature, because operating point is self tuning MPPT functions are adjusted to ensure solar module always with maximum output power.Equivalent to one electricity of miniature DC/DC current transformers Pressure, power pack, it is equal to convert front and rear power.Therefore, discounting for loss, the power that controller is provided to load is just Will be essentially equal with the power that is obtained from solar module, this is actually also the original intention of actual MPPT controller design. It is to be based on this argument, the analysis to co-ordination mechanism between distributed generation system each unit module below.
Under conditions of the output power of all modules and load determine, following results are set up：
(1) total current of series arm is determined by the general power and loading condition of all modules；
(2) output end voltage of each module accounts for the ratio of the general power of all modules according to its output power and distributes automatically；
(3) when the output power increase (or reduce) of some module, the total current of series arm, which will increase, (or to be subtracted
It is small)；Correspondingly, the voltage at the module both ends will increase (or reduction), and the voltage at other module both ends
It will reduce (or increase).
Using these conclusions, the co-ordination process between each module of distributed photovoltaic system can be explained well, wrapped Include the adjusting process of module system during excision is linked into.Operating point self-coordinating MPPT controller module is shown The voltage and current of the characteristic of " power source ", i.e. port is there are restriction relation, but module only works as module in itself without solution is limited When accessing circuit, one of voltage or electric current are just subject to external constraint, can just determine unique solution；When circuit condition changes When, port voltage and electric current also change, but the power exported remains unchanged.
The driving control system of the present invention：The electrical energy devices of electric automobile come from two kinds of solar-energy photo-voltaic cell and power supply Charging modes, solar panel produce electric current under irradiation by sunlight, are charged a battery by photovoltaic controller, then by storing Battery is to motor and other load supplyings.When solar panel produces electricl energy, after being connected with control device and energy storage device, Connected and loaded by the other end again, load is exactly the motor (driving device) of electric automobile.During general electric car operation, changed Solar energy load is directly taken by control device, and when stagnation of movement or sufficient sunlight, the electric energy of remainder is to storage Battery charges and stores, and when sunlight is insufficient, is powered to the load at the same time by solar-energy photo-voltaic cell and storage battery；Work as vapour Car slows down or during braking, should have " recyclability brake apparatus ", by electric flux by controller, engine is become motor, Storage battery is redirected back into be stored.Such complementary uninterrupted power supply technology, can improve and weather heavy dependence is lacked Fall into, improve the performance of solar telephone.
The present invention is left unused on daytime and the illumination preferable time can be generated electricity by solar panel, then leads to electric energy Cross photovoltaic controller to charge to ferric phosphate lithium cell group, lithium iron battery group produces electric current driving automobilism again.For long-distance trip The needs of row or prevention rainy weather, add extraneous charging interface in storage battery group.
Adversely affected to solve component output characteristics difference caused by whole photovoltaic generating system, improve the whole of system Body efficiency, most effective means are exactly to use distributed control mode, by being carried out respectively to assembly set as small as possible MPPT is controlled.Using string type MPPT controller can in the maximum functional point of input terminal real-time tracing solar battery group, Output end controller is converted according to external circuit situation by buck, makes to realize that operating point matches between multimode, so that real The at utmost output of existing solar battery array power.String type structure MPPT has three advantages：1. blocking diode need not be set, can Reduce the loss of array；2. each component has inverter, the extended capability and redundant ability of system are all stronger；3. need not be straight Flow busbar.But since traditional string type can not solve the problems, such as the property difference of various components inside branch, and the hot spot brought The problems such as more peak characters of power loss, power caused by phenomenon, shade, can not still solve, therefore will be each solar cell Component is all equipped with a miniature DC/DC power converter, to change output characteristics, it is always worked on maximum power point, This compound unit is carried out series and parallel again to connect, it is possible to form an efficient photovoltaic power generation array.
Solar panel uses non-crystalline silicon/crystal silicon laminated construction solar cell.Micro-crystalline silicon cell and amorphous silicon battery Compare, microcrystal silicon is not only with the low optical band gap similar to monocrystalline silicon, it can be achieved that high current density；Also there is the light of very little Attenuating effect is caused, stability test can be significantly improved.But the shortcomings that micro-crystalline silicon cell, is that it is indirect band-gap semiconductor, short The absorption coefficient of light of wave band is lower than non-crystalline silicon, therefore to realize that high short-circuit current density needs the absorber thickness more than 1 μm. Therefore, in view of the good short wave response characteristic of non-crystalline silicon and the good long-wave response characteristic of microcrystal silicon, common microcrystal silicon make bottom electricity Pond, forms amorphous silicon/microcrystalline silicon tandem structure, can increase substantially transfer efficiency.
The battery of electric automobile uses ferric phosphate lithium cell.Ferric phosphate lithium cell belongs to lithium rechargeable battery, main to use Be used as power battery, and its discharging efficiency is higher, and efficiency for charge-discharge can reach more than 90% in the case of multiplying power discharging, and plumbic acid Battery is about 80%.In the battery, the security of ferric phosphate lithium cell can reach also above other batteries, theoretical service life 7~8 years, actual life was about 3~5 years, and the ratio of performance to price is theoretically more than 4 times of lead-acid battery.
The present invention is that can accommodate the minicar of three to four people, is reduced as far as unnecessary space, such Miniature Car has lighter weight, and less energy intensive, this can also effectively improve the cruising ability of battery, and build is smaller than general-utility car Very much, this can a degree of situation for alleviating peak period congestion in road on and off duty in city.
The basic principles, main features and the advantages of the invention have been shown and described above.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its Equivalent thereof.
