The digitial controller is made of DSP+FPGA devices, and the core important document of this system device, this core are constituted with this
Component completes embedded internal network and couples with data/address bus, and is realized by network system and coupled with external system.
Digitial controller extracts data to BMS battery management systems, the data that circle collection each time obtains is compared analysis, really
Single battery to be processed needed for fixed：It is essentially two single batteries with peak capacity and lowest capacity, two lists
The selecting object that body battery will be disposed as this, by calculating the energy number for also obtaining and needing to shift.Digitial controller according to
This information determines the initial capacity quantity of transfer energy and terminates capacity quantity, according to this quantity, completes to convert inversion
The control of device, to obtain suitable initial capacity.Control matrix by the Multi-position switch that is coupled, send out determined by specifically open
Off position.One energy transfer process can be completed within the period of Millisecond, completes the measured value after energy transfer, passes through
BMS battery management systems are corrected again.Therefore system can enter the cycle of next round, carry out down in cycles
It goes, until all single battery energy are obtained new balance.
Dynamic lithium battery group is by B1~Bn-1Battery, the battery pack of composition is that this system needs the object that balances, and n's takes
Value is to depend on the processing capacity of battery management system chip, and in present embodiment, the chip of BMS battery management systems parses energy
Power is 12, therefore takes n=13.It is noted that this system can be balanced pipe to the cell numbers such as 12,24,36,48
Reason, with the update of chip, quantity is can to change.
BMS battery management systems are completed to acquire the data of 12 batteries, acquisition parameter is by front and back 13 connection lines
The voltage and current of single battery, by the electricity for calculating obtained single battery.The parameter that the present apparatus is obtained passes through inside
Network completes the data transmission to digitial controller, and analysis is compared to these parameters by digitial controller, makes corresponding
Operation processing.
Digitial controller determines this week interim required energy transfer target completed after completing data analysis,
In present embodiment, it is assumed that system needs after comparative analysis by lithium battery B2Excess energy be transferred to lithium battery B5In
It goes, realizes the energy balance of epicycle.Digitial controller controls matrix completion pair then according to set sequential by Multi-position switch
Battery cell switch K2, K3 and K5, the operation of K6 are open-minded.In order to obtain correct polarity of voltage, when coordinating above-mentioned action, also
It needs to control matrix majorization polarity switch by Multi-position switch to be assisted.
Complex equilibrium process, the following (note of sequential of this operation：Unmentioned switch is in off state)：
1., polarity switch KJ2+, KJ1- be closed：To take lithium battery B2On energy obtain correct polarity of voltage and (protect
It holds).
2., single battery switch K2, K3 be closed：Open lithium battery B2Connection, at this point, energy is passed by inversion converter
It is handed to super lithium capacitance, disconnects all switches after the completion.
3., single battery switch K5, K6 be closed：Open lithium battery B5Connection (holding).
4., polarity switch KJ1+, KJ2- be closed：To give lithium battery B5It uploads delivery of energy amount and obtains correct polarity of voltage.
Above four make and break process are to complete the one-to-one energy transmission of battery, and such action will in cycles, directly
Until all batteries are in equilibrium state.The above process is the operating process of Multi-position switch control matrix.
Inversion converter uses DC/DC processing units, completes to take out the energy of 12 batteries into required part, be sent to
Super lithium capacitance, the voltage class after transmission, the energy of transmission are provided by digitial controller.
Super lithium capacitance is the carrier for transmitting energy, and due to there is super lithium capacitance, external behavior has super electricity
Hold the double characteristic with dynamic lithium battery, existing power characteristic, and the energy transfer properties of dynamic lithium battery can be met, therefore,
Relaying utensil using this electrical installation as energy transmission has stability good, electrical characteristic parameter matching, control switch letter
The advantages such as clean.
In order to enable the first busbar and the satisfactory positive-negative polarity of the second busbar, completed by 4 polarity reversing switches
To the correct switch of polarity of voltage, to ensure in all lithium battery monomers with super lithium capacitance when coupling, corresponding pole
Property is not missed accurately.From fig. 1, it can be seen that the polarity of voltage of the first busbar can according to KJ1+, KJ2+, KJ1-, KJ2- it is different
Unicom combination is changed, and polarity will be reversed each other with the second busbar institute, this purpose is to realize battery cell (B1~B12),
It is correct with the polarity of voltage of super lithium capacitance.Similarly the polarity of voltage of the second busbar can also according to KJ1+, KJ2+, KJ1-,
Unicom combinations different KJ2- are changed.
Battery cell switch uses the direct articulated electronic switch of FATMOS compositions, and simple in structure, manipulation is easy,
It is big (200A) to control electric current, by selecting voltage, controlled electric current can be met, the manipulation of matrix is controlled in Multi-position switch
Under, sequence is controlled by digitial controller algorithm, realizes circulate operation in sequence, until all energy contents of battery are put down
Weighing apparatus.
Entire control system in operation, will be divided into the following steps：
The first step is continuously dynamically tested lithium battery group by BMS completions, after digitial controller obtains these parameters, is obtained
It takes the capacity of the corresponding single battery of ceiling voltage and selects the single battery of the low capacity to match.
Second step, according to selected pairing battery, digitial controller will provide the opposite switch in requisition for closure, in addition to
These are needed other than closure switch, remaining all switch is in off-state (high-impedance state being not turned on).
Third walks, and the switch conduction sequential arranged according to the present apparatus completes the conversion of energy.
4th step, after completing this action, digitial controller is by the new appearance that is obtained of acquisition BMS battery management systems again
Measure data, voltage data.
The mode of above-mentioned energy transmission is referred to as " active energy transmission " balanced way, its advantage is that, substantially without increasing
Add additional supplement energy, the balance of energy is can be achieved in limited range, since the instantaneous power of super lithium capacitance is opposite
Much larger with lithium battery, therefore, entire transmittance process will be completed in very short moment, when once balance is completed, and can be with
It is last until the battery of all administrations is fully completed equilibrium into a new wheel balance.
The present apparatus is to have been directed to the characteristic of dynamic lithium battery, makes full use of the energy transfer properties of lithium battery, use super
Carrier of the lithium capacitance as energy transfer, but because super lithium capacitance has had both the energy of the high-power moment transfer energy of super capacitor
Power, while having the characteristics that the long-life has extended cycle life, it is quick as the carrier of energy that super lithium capacitance is utilized in the present apparatus
Carry out dynamic power transmission.
Also have the advantage that voltage value can float, and adopt as equilibrium energy carrier using " super lithium capacitance "
After floating equalizing voltage, the switch that control is connected just becomes very simple and direct, and only need to complete simple break-make can reach
Required purpose (in the present invention, using single FATMOS devices), this for numerous number of switches in the present invention,
System will become simple and reliable.
