Description
Technical field
The present invention relates to the solar domestic energy resource system that illumination and electric power are provided for consumer.Specifically, the system
The consumer for being designed to power without national grid or intermittently accessing in the area that national grid is powered.
Background technology
It is estimated that can not obtain electric power more than 1,600,000,000 people, in this case, illumination deficiency has very big to quality of life
Influence.For most developing countries, only light source is burn wood, excrement, candle or kerosene, this be it is harmful and
Unsustainable.In order to overcome this problem, many off-network rural areas can use solar energy home system (SHS) now.
Typical SHS is made up of photovoltaic (PV) panel, battery, charge controller and some loads (equipment).Battery storage is received by panel
The energy of collection, charge controller prevents battery from overcharging, and it (is typically one or more lamps, mobile phone charging to load
Ability and such as midget receiver, television set, tablet personal computer, other consumer electronics of notebook computer or similar products
Some combination) electric power is obtained from system.These systems are for example described in the following documents：SIMbaLink：
Towards a Sustainable and Feasible Solar Rural Electrification System；Nahana
Schelling et al.；Proceedings of the International Conference on Communication
Technologies and Development(ICTD)；London,UK,December 2010.
It is by pay-as-you-go (PAYG) or progressively buying pattern offer that many SHS, which are installed, because consumer can not be direct
Purchase of equipment, but nominal amount is paid for the unit, their uses to the unit are then paid with small increment, generally
It is that they buy the half of the cost of kerosene on an equal basis.The various mechanism for being collected money can be used, for example, are passed through
Mobile phone described in US2013212005.
The problem to be solved in the present invention
One of SHS subject matter is that available horsepower is not always sufficient to provide the abundant profit to all devices in system
With.This is probably that PAYG credit lines will may be used up because over time, battery electric quantity is not enough, or because
Some dates are cloudy, and solar panel can not think that night prepares by battery is fully charged.In these cases, usual SHS will
Operation is discharged up to battery, is then shut off.However, from the perspective of terminal user, and the equipment of not all status all
It is identical.May be more important than the phone charging of extra a few minutes for example, obtaining a small amount of light.Accordingly it is highly desirable to have
There is some form of electrical management to predict typical illumination and electricity needs and distribute energy resource so that equipment can be
Operated in usage time interval needed for it.However, in order to optimize the mode of battery charging and the mode of consumed energy, being desired based on
History is charged and the estimation of use pattern is charged and discharged strategy to adjust.
The content of the invention
Inventor develop a kind of use SHS component come with the time passage monitor consumer's use pattern and by its with
The system that one or more feature modes match, the feature mode can be represented with template form or other modes.SHS
From parameter (such as panel voltage, panel currents, battery charge, cell voltage and the electric discharge electricity of its available various output
Stream) carry out inferential information.Time, weather condition, the time in 1 year and the history that the information is used in estimating one day can use sunlight
Level, with the pattern of the available charging current of the dynamic estimation system and can energy.Then use the information to change battery
Charging modes.For example, under conditions of sunlight extension is expected, reducing charge rate, so that battery life is maximized.So
And, in the case where expected sunlight will only can use (this normally results in the not enough electric charge of battery receptacle) in a short time, increase is filled
Electric speed is so that the energy maximization of storage.
Similarly, the historical current consumption to output is monitored, and the system uses the information to estimate possible use
Situation-differentiation principal light source (generally at night with morning open the long period), bedroom light (generally at night with morning open compared with
Short time) and exterior light (generally being opened in whole evening).The information is used to provide performance objective for system together with usage amount,
I.e. preferable typical use.
The system is made on system operatio using estimation that pair can be with rechargeable energy and the idealised typical purposes
Determine.In the case of the electricity needed for available power is less than ideal operation, the system is known exemplary requirement profile using it
Which know to select to place distribution electric power.If for example, being illuminated daily usually using 6 hours, the system will select to adjust
Luminous intensity is to be kept for this duration, rather than offer total power is illuminated within a short period of time.Similarly, the system will be to electric power
Route selected, for example accessory device or phone charging relative to illuminating power.
In a similar way, if the system is the pay-as-you-go SHS using charge according to energy, when utilisable energy volume
When degree is less than in preset time section to the amount needed for all output power supplies, the system can adjust the electric power output of system, with
Just compared to TV etc. more free building layout service, the basic service that priority treatment is such as illuminated etc.It will be understood that, with
On refer to that money is charged to the reference of " charge " in pay-as-you-go SHS context.Reference to " utilisable energy amount " is
Refer to the money remaining sum of the user associated with SHS.

Embodiment
The present invention optimizes the charging and discharging of solar energy home system using adaptive technique.Figure 1 illustrates SHS
Typical Disposition.SHS can use known technology to build, for example, solar panel (1) can be by any of photovoltaic skill
Art (for example, monocrystalline silicon/polysilicon, III-V, non-crystalline silicon, film (CdTe, CIGS, dye sensitization, organic matter, nano particle))
To build.Equally, solar panel can be the solar panel of exploitation in the future.Rechargeable cell (2), which can be selected from, appoints
What existing or following battery types, such as sealed lead-acid, nickel metal hydride, and preferably LiFePO4 kind
Class.The system is the commonly provided from several watts to the dc power of several hectowatts, but preferably exists in 2.5W to 200W or more preferably
In the range of 2.5W to 50W.System controller (3) can use component known to the technical staff of circuit design field to carry out structure
Build.It is usually using microcontroller and desired function as described below can be realized to build with any amount of configuration.
In order to optimize charging, the system is generally by regularly making solar panel short circuit to measure short circuit current flow, to survey
Measure luminous intensity.By the way that electric current is related to timer internal, within the time of some days, the system can be with certain certainty
Determine the duration on night and daytime.Based on this, it can be estimated and season estimation in real time.Within one day, one
A little solar energy patterns are with characteristic, such as sunny, cloudy, intermittent sunlight.In some times of 1 year, these
Pattern is that with characteristic, such as morning is sunny, thunderstorm in afternoon.By the way that lamp light mode and the template of storage are compared,
The possible synoptic model of the system estimation.This comparison provides the estimation to the same day available expected light.Will expected light and charging
Required light is compared, and the charge rate of battery is adjusted, to minimize the transient current for inputting battery
The probability that optimization is charged to battery simultaneously, so that battery life is maximized.
Above-mentioned calculating can be locally executed in equipment, or be transferred back to remote server or computing device, described

Individual be such as compartment lamp (being used for a long time at night and morning), bedroom lamp (being used at night and) and external modulation the short time in the morning
(being switched on whole night).
Similarly, the system usually used total load current of measurement consumer based on daily.The information is used to create
Build targeted loads.
By measuring solar panel electric current, dusk can be estimated with certain accuracy.This likely corresponds to battery
Maximum charge point.Charge available is compared by the system with aimed charge, and if charge available is less than aimed charge,
Then the luminous intensity of lamp will be reduced using such as pulse width modulation so that meet light duration target, although brightness is relatively low.
Performance of the system based on record is adjusted.If being discontented with foot-eye although being adjusted to light output
Charging, then target charging will gradually increase, so that in the future days, light output percentage is further reduced.Similarly, such as
Fruit battery has the remaining residual charge when the sun starts to recharge battery, then reduces target charging.By this way, should
Adjust to be intended to satisfy that by the illumination duration target set by the use of consumer, but regardless of charging system self-adaption
How is the amount of sunlight of period.The process can be run within the time of one day, or be polymerize within the time of some days.If disappeared
The person of expense needs the unrestricted electric power time, then can also provide the option for surmounting adaptive behavior.
As it was previously stated, above-mentioned calculating can be locally executed in equipment, or be transferred back to remote location, described long-range

The operating voltage that is measured during system) measure luminous intensity.Especially, system controller can by make itself and battery and equipment electricity every
From measuring luminous intensity regularly measuring the open-circuit voltage of solar panel.By the way that curtage is measured and internal timing
Device is related, and within the time of some days, system controller can determine the duration on night and daytime with certain certainty
And the high noon on the same day.Based on this, it can also estimate dawn and the time at dusk, the local zone time on the same day and season.
System controller uses the information collected according to the demand current of each connection equipment and its to daytime or night
The knowledge of time, to determine for the possible daily use profile (be referred to here as use pattern or use profile) of each equipment.
For example, the use profile of equipment can be included in 24 hours one group of data that (or other times section) collects, including
The electric current obtained during the period by interval (for example, every 5 minutes) by equipment.In the negative of the SHS including one or more lamps
In the context of load, system controller can at least recognize the demand current of lamp, the typical time period amount during daytime using lamp
And the Typical duration of lamp is used at night.
System controller uses the charging current of (i) rechargeable battery and discharge current (this paper of rechargeable battery
Also referred to as total load current)；And/or the voltage of (ii) rechargeable battery, the level for estimating available battery power.
In embodiment, system controller is set up using the luminous intensity of measurement and the use profile of each equipment for the moment

Plate, which can be stored in, to be couple in the memory of system controller 3.Memory can be to system controller it is local (for example,
Either with system controllers package in identical unit on same PCB) or away from system controller (for example, cloud
Storage).
SHS can also include preventing the charge controller of battery overcharge.Charge controller is used from monitoring photovoltaic panel
Array (for example, open circuit) voltage or photovoltaic panel array (for example, short circuit) electric current or battery charge (that is, the charging of battery
Electric current and discharge current) or the collected information of certain combination of cell voltage or all these amounts change the charging side of battery
Formula.For example, many battery chemistries require batteries with constant current charge until cell voltage rises to predetermined voltage, afterwards
Battery should with generally with the predetermined voltage identical constant-potential charge, can be with or under conditions of with Gaoyang light level
Battery charging rate is reduced, so that battery life is maximized.In addition to the above-described effects, system controller can indicate charging control
Device processed stops charging to battery or increasing the charge rate of battery or reduces the charge rate of battery.Although charge controller can be with

As described above, system controller can be used from monitoring photovoltaic panel array voltage (for example, open-circuit voltage) or light
Certain of underlying surface plate array electric current (for example, short circuit current flow) or the two amounts combine collected information to distinguish daytime and night
Between, can also use it for estimation weather condition, the time in 1 year and history can use sunlight level, expected with dynamic estimation
Period (for example, one day or one week) in the pattern and possible amount of the available charging currents of SHS.Then this can be used
Information changes the charging modes of battery.For example, under conditions of sunlight extension is expected, reducing charge rate, so that electric
Pond lifetime.However, only will can use in a short time (this normally results in the not enough electric charge of battery receptacle) in expected sunlight
Situation (such as in rainy season) under, increase charge rate so that storage energy maximization.
It will be understood that, SHS can include the other elements not shown in figure, such as user interface and/or inverter.
