As preferably, the model that described high accuracy integrated power supply managing chip adopts is AXP171.
Compared with prior art, the beneficial effects of the utility model are: basic overcharge except possessing, cross and put, the overcurrent, short-circuit protection, limitedly to greatest extent utilize available energy in the battery pack.The every economize on electricity core of battery pack is is all discharged and recharged fully, and portfolio effect is remarkable, limited prolongation battery pack useful life and suitable standing time; Equilibrium just can be opened when electric core consistency goes wrong and meet above-mentioned two conditions, and reducing equalizing circuit influences electric core.
Description of drawings
Fig. 1 is system construction drawing of the present utility model.
Embodiment
The technical solution of the utility model the utility model is further specified below in conjunction with accompanying drawing in order more to be expressly understood.
Novel high intelligent equalization baffle described in the utility model; comprise inspection center, control unit and balancing energy module; described inspection center is connected with the two-way communication of balancing energy module; described balancing energy module is connected with the control unit two-way communication; described inspection center adopts high accuracy integrated power supply managing chip; described control unit is made up of metal-oxide-semiconductor, and the model that described high accuracy integrated power supply managing chip adopts is AXP171.Inspection center also comprises auxiliary element, the built-in high-accuracy voltage detecting circuit of high accuracy integrated power supply managing chip (IC) overcharges, overdischarge, electric current excessive (overcurrent) during discharge, the peripheral circuit short circuit all can accurately detect, and drives corresponding electronic device action; There are input, output current and time of repose supervisory circuit in protection IC inside, and battery pack current and time of repose are precisely detected.Protection IC issues right instructions according to Monitoring Data, and order energy back module and corresponding device move; Auxiliary element is made up of resistance, electric capacity, renewable type fuse etc., and in whole testing process, the battery pack of the auxiliary element auxiliary protection IC core situation of respectively economizing on electricity is monitored; When the protection IC corresponding instruction of issue accurately at a high speed appears when unusual in battery pack electricity core; Moved rapidly by auxiliary element, battery pack is made corresponding protection.
Control unit is taken as the leading factor with metal-oxide-semiconductor, and electronic device cooperates to be formed, and MOS FET regard it as a special switch so long in electronic circuit.Battery pack is in carrying out the charge and discharge process, and the protection IC battery pack core that respectively economizes on electricity is monitored; When battery pack was normally moved, the rapid issuing command of protection IC was to metal-oxide-semiconductor, and the metal-oxide-semiconductor grid G can obtain a high level, then switch ways between the D.S; Electric current passes through between D.S, otherwise electric current can not pass through.
Traditional protection plate balanced way is to utilize resistance to consume energy latter stage in charging; Be all power resistors in parallel of the every economize on electricity core of battery pack, the electric core that at first reaches certain voltage carried out the balanced way that reduces charging current even do not have charging current.This balanced way time for balance is short, euqalizing current is less, DeGrain.
Equalizing system in the novel high intelligent equalization baffle adopts Based Intelligent Control, to the battery power discharge process and cross and put the protection back and carry out the syllogic action, is respectively the excess energy stage of transferring, makeup energy stage, energy to reclaim the preliminary filling stage.Reduce energy loss in the transfer process to greatest extent, improve energy and shift utilization ratio.Cross to put and make after the protection core that respectively economizes on electricity in the battery pack all be in discharge near complete emptying state, the core that respectively economizes on electricity when being convenient to batteries charging all can be full of fully; Preliminary filling process after energy reclaims can suitably increase battery pack standing time, avoids growing partially standing time battery pack and the heavy losses phenomenon occurs.
Equalizing system in the novel high intelligent equalization baffle adopts Based Intelligent Control, to the battery power discharge process and cross and put the protection back and carry out the syllogic action, is respectively the excess energy stage of transferring, makeup energy stage, energy to reclaim the preliminary filling stage.Detailed content is as follows:
Transfer the excess energy stage:
Novel equalizing system is carried out equilibrium latter stage to battery power discharge, when battery pack is in the discharge process, when certain economize on electricity core voltage is down to certain value and single-unit ceiling voltage and minimum voltage pressure reduction when being not less than 50mV, intelligent IC is to the equalizing system issuing command after satisfying above-mentioned two conditions, make it carry out work respective switch Q2 ... the Qn conducting, energy transfer module in the equalizing system according to the instruction of intelligent IC to voltage, the the 2nd to n higher relatively economize on electricity core of capacity carries out portion of energy to be shifted, the portion of energy that is about to the 2nd to n economize on electricity core is transferred in the energy transfer module, subsequently switch Q2 ... Qn closes.(be example with ternary electricity core, balanced cut-in voltage is set at is down to 3.2V, crosses to put protection voltage 2.75V; On the low side with the first economize on electricity core voltage, residual electricity core voltage is higher to be example).
The makeup energy stage:
The intelligent IC issuing command makes switch Q1 conducts energy shift module charge with the electric current that is not higher than 2A the 1st economize on electricity core to low-voltage, crosses until battery power discharge and puts protection.This energy transfer module adopts super low-power consumption, super-low resistance device to form, and reduces energy loss in the transfer process to greatest extent, improves energy and shifts utilization ratio.
Energy reclaims the preliminary filling stage:
After battery pack is crossed and is put protection, intelligent IC is assigned new instruction to equalizing system, impel it to work on voltage, the higher about 1A current discharge of electric core of capacity are reclaimed into energy transfer module, in the capacity of emitting and battery pack, cross at first and put the electric core capacity of emitting of protection and equate; Prerequisite is to continue the 1A electric core voltage that discharges must be higher than single-unit and cross and put protection voltage, and this work step stops if being lower than then.Intelligent IC issuing command after above-mentioned work step stops to make the energy transfer module self-energy with equal current system the core that respectively economizes on electricity in the battery pack be carried out precharge.Above-mentioned high power capacity electricity core energy is reclaimed makes the core that respectively economizes on electricity in the battery pack all be in discharge near complete emptying state, and the core that respectively economizes on electricity when being convenient to batteries charging all can be full of fully; Preliminary filling process after energy reclaims can suitably increase battery pack standing time, avoids growing partially standing time battery pack and the heavy losses phenomenon occurs.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
