Description
Technical field
The present invention relates to a kind of classification drive battery system, specifically, relate to the heterogeneous large power, electrically cell system of a kind of oil electric mixed dynamic and electronlmobil classification, particularly control the electric energy release rate that flows into consumer (as oil and electricity hybrid vehicle and battery-driven car) from the secondary cell group, thus the heterogeneous large power, electrically cell system of classification that consists of.
Background technology
Global Greenhouse Effect and oil reserves descend and in recent years become the major issue of public concern, people's active development battery-driven car and oil and electricity hybrid vehicle (mixed motor-car), and this class automobile all uses the high power battery group that surpasses a kilowatt hour.The high power battery group is the main power source of battery-driven car and the auxiliary power source of mixed motor-car.Battery pack adds that by many groups or multiple batteries battery management system forms usually.Battery management system monitoring voltage, electric current, and the situation that discharges and recharges of measuring and calculating battery pack.
The high power battery major part that mixed motor-car and battery-driven car use is lead-acid battery and Ni-MH battery.These batteries discharge and recharge in dark circulation (deep cycling) and under sudden change high magnification electric current, and can be very limited service life.For example, the battery of general sharp this (Toyota Prius) automobile of Toyota charges and discharge state and maintains 40% to 80% scope, makes it keep longer design service life (160,000 to 240,000 kilometers).So, 60% capacity of cell is not used in drive routine.
Some new battery chemistries raw material (as cobalt acid lithium, LiFePO4 and LiMn2O4) is in the situation that there is monitoring can reach longer service life, and they are lightweight, and energy density is higher.Yet if their life-spans become of short duration equally in the situations such as high magnification current discharge and charging overvoltage, in the situation that speed of a motor vehicle transition causes the big ups and downs of electric current demand, they are even durable no more than lead-acid battery and Ni-MH battery.
At present, a kind of universal method that mixed motor-car is converted to " inserting the mixed moving battery-driven car of charging " (the Plug-in HybridElectric Vehicle) that lay in than macro-energy is: direct increasing and upper another road battery pack (secondary cell) in parallel in first wife's battery pack (main battery), and add bang-bang circuit.Due to the battery chemistries composition and the nominal voltage level different, this serious overbalance can occur, and can shorten battery; Such assembled battery module can only discharge and recharge in the scope of car manufactures set, and therefore, capacity greatly can fully not used yet.The part experimental technique proposes " deception " former factory automobile controller, force it to use more macrocell capacity, performance greater advantages, but, because needs are changed the control program that dispatches from the factory, the secondary action of doing like this is expensive and on the impact of former factory department part, simultaneously, can produce higher than intrinsic discharge amount of exhaust gas, this obviously deviates from mutually with the original intention of controlling exhaust emission.
The method that another mixed motor-car repacks " inserting the charged hybrid power battery-driven car " into is that former factory battery pack is all changed into high capacity cell.Can solve so unbalanced problem between battery, but use the several years owing to will extending battery, still be used the restriction of capacity; Simultaneously, do like this cost very high, also can cause the discarded environmental problem that causes of used batteries.
The U.S. 5 in issue on June 29th, 1993,223, in No. 351 patents, Wruck proposes dual battery system: do not isolate the battery system that directly is communicated with two different nominal voltages with not controlling by conv, but its disadvantage is: the main battery that voltage is higher can instead fill secondary cell, causes energy to flow to secondary cell from main battery.Along with time lapse, the voltage of two Battery packs can be convergent, becomes nominal two a string battery pack in parallel.
It is a principal object of the present invention to, by the heterogeneous large power, electrically cell system of management classification, extend battery and reach larger capacity, wherein master battery pack cope with transients load, and the secondary cell group is born constant load under the prerequisite that causes minimal impact to master battery pack.

A kind of classification drive battery system comprises: a main driving battery pack connects electric motor drive system; A plurality of and described main driving battery components every pair drive battery pack; DC-DC conv and controller are limited the quantity of and shift the device of energy to described main driving battery pack from the described secondary battery pack that drives with regulation output electric power; A kind of device of measuring described main driving battery set charge/discharge state; A kind of device of measuring described secondary driving battery set charge/discharge state.
The present invention is divided into the classification battery pack to battery, interconnects by DC-DC conv and controller (direct current change over controller), extends battery and increases active volume.During the automobile acceleration and deceleration, shallow circulation (shallowcycling) and set charge and discharge status level in the main battery module (group) that operates bear the transition load supplying, secondary cell module (group) is assisted constant load with dark circulation (deep cycling).
The master battery pack that total volume is less is formed by a plurality of battery-arrangements, discharges large momentum electric power when automobile accelerates, and reclaims the energy that large momentum generates electricity again when braking automobile.Main battery charges and discharge the scope that status level remains on setting, between 40% to 80%, so just can reclaim electric power in the situation that do not overcharge main battery when brake, simultaneously can also be in the situation that only put the large momentum electric current of generation.
The secondary cell group that total volume is larger is formed by a plurality of battery-arrangements, by " direct current change over controller " and main battery coupling, supply with less constant vehicle drive power, perhaps pause or little driving power demand stage charges to main battery at automobile, such as low speed driving and the cruise etc. the time.Secondary cell almost completely discharges, to approaching the null value (0%) that charged and discharged at that time state; Simultaneously, almost completely be charged to 100% of the state that charged and discharged at that time.
Over-charging of battery and cross is put can the heavy damage battery, shorten its service life, but and secondary cell is all quantitatively and anticipation owing to charging and discharging, capacity of cell can be used cmpletely, and the super-charge super-discharge phenomenon can not occur.
" direct current change over controller " monitors the electric current and voltage of major and minor battery simultaneously, and the charging and discharging state of two Battery packs of testing and assessing.If the charging and discharging state of main battery reaches the upper limit of range of control, perhaps secondary cell drops to the lower limit of range of control, and it just stops charging to main battery." direct current change over controller " drawn electric energy and it converted to the voltage that mates with main battery from secondary cell.The direct current (DC) output of " direct current change over controller " is limited in adjustable scope.
