Description
(1), technical field: the utility model relates to a kind of battery module, particularly relates to a kind of rechargeable power battery module.
(2), background technology: at electrokinetic cell applied technical fields such as electric bicycle, hybrid vehicle, electric automobiles, for technical need aspects such as the high-rate discharge ability of electrokinetic cell, high magnification charging performance, high output voltage, highly charged capacity, the cell technology can't satisfy.Thereby, the monomer electrokinetic cell need be connected and composed the electrokinetic cell module by series, parallel or mixing, satisfy the technical needs such as high power capacity, high voltage and big electric current output of high power electricity servo applications technical field to electrokinetic cell.
The lithium-ion-power cell group have energy density height, specific power big, have extended cycle life, plurality of advantages such as capacity is big, internal resistance is little, therefore in electric automobile, obtained increasingly extensive application.
Under existing lithium ion battery technical conditions, because of the restriction of its technology mechanism, lithium ion battery is lower to the overload ability to bear that overcharges, and operating characteristic at high temperature is relatively poor.If charging is improper, not only can causes the irreversible damage of monomer lithium ion battery, even can produce pernicious consequence such as blast.Facts have proved, only the charged capacity of monomer lithium ion battery is simply done greatly not only have bigger technology difficulty, and the output voltage of monomer lithium ion battery, can not satisfy the demand of nearly all high-power drive pond applied technical field to high output voltage.Thereby the lithium-ion-power cell of high output voltage, big charged capacity can only be realized by tandem type or hybrid type lithium ion battery module mode.
Under existing lithium ion battery system engineering condition, the charged capacity of volume production monomer lithium ion battery certainly exists certain consistency difference.When constituting battery pack,, then can cause partial monosomy battery overcharge or overdischarge at the charge and discharge process of series loop if the charge and discharge balancing control and management is mishandling by the monomer clang ion battery series connection that has consistency difference.And ager process along with battery pack, overcharge or cross due to the material flaw put phenomenon and all can impel the partial monosomy battery, the system engineering process difference consistency difference and amplify dominance, aging and the periodic duty life-span condition differentiation of accelerating part cell finally can cause battery pack to lose efficacy fast because of the partial monosomy battery produces irreversible damage.
During battery overcharge,, can cause the variation or the destruction of positive electrode structure from active material, thereby produce heat, may also can disengage oxygen because lithium ion is moved out; When overcharged voltage during greater than the window voltage of electrolyte solution, electrolyte solution when the heat that reaction is emitted makes battery temperature rise to the decomposition temperature of electrolyte, is emitted a large amount of heat with oxidized reduction decomposition, and battery will be on fire from explosion.
For example, in the power battery pack charging process, wherein some or certain is several to be had the higher voltage batteries monomer and can earlier enter the state of overcharging than other battery cells, at this moment, if continue as the power battery pack charging, the battery cell that overcharges just may polarization be strengthened, be heated up and aggravate, so that burning even blast take place.If promptly stop after the higher voltage batteries monomer overcharges though can avoid taking place security incident, can't guaranteeing that other battery cells completely fill, thereby causing the waste of part battery capacity having to whole battery group charging.
Therefore battery overcharge is the main cause that causes the accident, and should prevent as far as possible and avoid.Existing solution is:
1. add protective circuit, monitor the charging voltage of battery in real time,, adopt the voltage of the whole bag of tricks balancing battery monomer when voltage during greater than setting, main at present use has two kinds: a kind ofly be the energy consumption method, another kind is the energy transfer method.
The energy consumption method is that cell is in parallel with a pressure limiting load, and each pressure limiting load includes a resistance and a switch.During the charging beginning, switch all is in off-state.In the charging process, testing circuit detects the charged state of each battery cell, surpass setting voltage if find the magnitude of voltage of certain battery cell, the switch connection of its pressure limiting load then, make cell to the company conductive discharge, consume portion of energy and make voltage come back to set point, and then disconnect the switch of pressure limiting load, voltage until each battery cell all reaches set point, thereby realizes the equilibrium charging of battery pack.Obviously the energy consumption method can consume a lot of energy on the resistance of pressure limiting load, and simultaneously, the heat that resistance produces also can bring burden for the heat radiation of power battery pack.
In the power battery pack that adopts the charging of energy transfer method, all battery cells are all in parallel with isolated form DC/DC (straight-straight voltage changer) by switching array and testing circuit respectively.Isolated form DC/DC is generally a rechargeable battery that capacity is bigger.When beginning to charge, the rechargeable battery of isolated form DC/DC is in discharge condition, and opens circuit with each cell.In the charging process, find that the magnitude of voltage of certain battery cell surpasses setting voltage, then this battery cell be connected with isolated form DC/DC that battery cell promptly begins the battery charge for isolated form DC/DC by switching array.When the voltage of this battery cell drops to set point, cut off the shunt circuit between battery cell and the isolated form DC/DC, all reach set point until the voltage that makes each battery cell, thereby realize the battery pack equilibrium charging.But, above-mentioned charging system internal structure complexity, reliability is low.
2. add anti-overcharge additive in electrolyte, when charging voltage overshoot voltage, additive begins to carry out repeatedly loss-free redox, to consume unnecessary rechargeable energy.
Obviously, said method can increase the production cost of battery, and the performance of battery is brought bad influence.
