Description

A kind of non-dissipative equalizing control device
Technical field
A kind of non-dissipative equalizing control device, belongs to battery pack balancing control technology field.
Background technology
Miniature electric automobile is an important content of China's development new forms of energy strategy, during miniature electric automobile is increasingly becoming The requisite vehicles in short distance consumer's go off daily, the Main Bottleneck that at present restriction miniature electric automobile develops is Power battery technology and battery management technique.In recent years, the power battery technology for being applied to miniature electric automobile achieves rapidly to enter Step, such as the electric drive assembly technology of, metastable ferric phosphate lithium cell high using specific energy and significantly improves the lead-acid battery longevity Electric drive assembly technology of the capacitor type lead-acid battery of life etc., but the development of matched battery management technique delays relatively Slowly, trace it to its cause, be on the one hand because that the R ＆ D Level of battery management technique is not enough, be on the other hand then limited to miniature electric vapour The integral vehicle cost of car is required.
At present the battery management technique of miniature electric automobile relates generally to the balance charge/discharge administrative skill of battery pack, by energy The height of consumption type is divided into and damages equilibrium and non-dissipative equalizing, damages and balanced mainly crosses energy ezpenditure limiting electricity by certain The charging and discharging currents of the higher cell of voltage in the group of pond, realize its charging balance with the cell of low voltage, existing The usual way for having technology is the two ends series connection balanced discharge resistance and power switch in each cell, although the control of this mode System is simple, but wastes energy seriously, and because unnecessary energy is discharged in the form of heat energy, has one in closed battery case Fixed potential safety hazard, has gradually been eliminated and has used；Non-dissipative equalizing is to quickly grow a kind of cell balancing in recent years, mainly Principle is that by conversion equipment the part energy of high voltage cell is transmitted back to into battery circuit or low electricity is directly forwarded to In pressure cell, the energy-storage travelling wave tube used is mainly inductively or capacitively, and by repeated charge inductively or capacitively electricity is realized Each monomer battery voltage is in a basic balance in the group of pond, and this becomes the method generally adopted in prior art, also has partly grind in addition The person of studying carefully proposes the two-way non-dissipative equalizing control technology that a kind of utilization bidirectional, dc conversion module is realized.
During the utility model is realized, inventor has found at least there is problems with prior art：
1st, using inductively or capacitively, used as the intermediary element of each monomer energy transfer in battery pack, balancing speed is slow, for a long time Using portfolio effect is poor, precision is low；
2nd, using bidirectional, dc conversion module as each monomer energy transfer in battery pack intermediate module, high cost, difficulty With the popularization and application in miniature electric automobile.
Jing analyses find that the main cause of the problems referred to above occur is：
1st, need to be passed through between the adjacent cell of each two as the element of energy transmission using inductance or electric capacity Switching device is inductively or capacitively in parallel with one, opening and shut-off by controlling switch device, using inductively or capacitively realizing The transmission one by one of energy, due to being to transmit energy step by step, therefore balancing speed is slower；And because battery pack carries out for a long time multi cycle Discharge and recharge, especially during multiple deeper cavity discharge and recharge, the capacitive property difference between monomer will also become big, so as to speed-up capacitor or Inductance is aging, causes portfolio effect and precision worse and worse, causes the battery charging and discharging performance difference between each monomer of battery pack It is increasing；
2nd, using bidirectional, dc conversion module as each monomer energy transfer in battery pack intermediate module, i.e. each battery Monomer all connects connects again after a two-way DC/DC converter, because battery cell electric pressure is than relatively low, generally will Single battery, can be according to needing to carry out in a balanced way constant pressure or constant current charge-discharge control, this equalization methods used as low-pressure side Simultaneously all battery cells can be carried out with discharge and recharge, and the capacity situation for different battery cells controls charging and discharging currents, But it is because each single battery is required for a two-way DC/DC converter therefore relatively costly.
