Abstract
The utility model relates to a novel intelligent storage battery equalizer capable of performing the function of balancing the voltage of a single battery during the charging and discharging processes of storage batteries connected in series. The equalizer includes a battery pack formed by more than two serially-connected single batteries (E), and a voltage diving resistor (R) and an operational amplifier (IC) which are connected in series in the circuit of the battery pack; a node (B) for total voltage dividing in the circuit of the battery pack serves as reference voltage connected with a normal-phase terminal input terminal of the operational amplifier (IC), and a corresponding node (A) between two adjacent single battery bodies serves as sampling voltage connected with reversal phase terminal input terminal of the operational amplifier (IC). The equalizer has the benefits as follows: the single battery or the battery pack can be charged and discharged through the operational amplifier and a charging and discharging branch circuit, so that the dynamic regulation of the single battery can be realized, and the service life of the battery is prolonged.
Description
Technical field
The utility model relates to a kind of batteries that can use connecting in charge and discharge process, monomer battery voltage is played the novel intelligent battery equalizer of balanced action.
Background technology
As everyone knows, storage battery normally is in series as stand-by power supply by several cells, because there is foozle in each cell in manufacture process, the chemical reaction that takes place in the use is also not quite identical, and cause its state-of-charge to have difference, the voltage of each cell is had nothing in common with each other, so in charge and discharge process, when the output voltage of charger is one regularly, the voltage that each monomer battery voltage difference shows as is higher, what have is then on the low side, phenomenon may appear overcharging in the battery that charging voltage is high, and charging voltage low excessively may fill deficiency, same in the discharge process of battery, also, quicken the discharge of high pressure position battery because of the difference of each monomer battery voltage.Therefore each cell difference of existing voltage can progressively make the battery pack overall performance descend, and shorten the useful life of battery pack along with passing service time and increasing.
Summary of the invention
At above-mentioned deficiency, the purpose of this utility model is to provide a kind of voltage difference that can reduce each cell of series battery, effectively improves the storage battery novel intelligent battery group equalizer in useful life.
To achieve these goals, the technical scheme that the utility model adopted is: the novel intelligent battery equalizer, it includes the battery pack that two above cell E series connection constitute, be serially connected in divider resistance R and operational amplifier IC in the battery pack loop, the Node B of total voltage dividing potential drop is gone into end as the positive terminal that reference voltage meets operational amplifier IC in the battery pack loop, corresponding node A goes into end as the end of oppisite phase that sampled voltage meets operational amplifier IC between the adjacent monomer battery, the positive-negative power termination battery of operational amplifier IC or charger power positive cathode, the output terminated nodes A of operational amplifier IC carries out charge or discharge by operational amplifier IC to cell or battery pack.
The beneficial effects of the utility model are: will be connected node voltage between adjacent two cells as sampled voltage, and with the total voltage dividing potential drop node voltage in the cell circuit as reference voltage, insert the positive inverting input of operational amplifier, cell or battery pack to this node are judged, when node voltage is lower than reference voltage, can or discharge and recharge branch road by operational amplifier charges to this joint cell or battery pack, and when the voltage of this node is higher than reference voltage, can or discharge and recharge branch road by operational amplifier again this joint cell or battery pack are discharged, realize cell is dynamically adjusted.Because the branch pressure voltage of assembled battery total voltage can change cell along with the variation of total voltage as reference voltage, so in the charging and discharging of accumulator process, prolong the useful life of battery.
The utility model can be installed in the battery case or in the charger because circuit is simple, volume is little.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is one of electrical schematic diagram of the present utility model.
Fig. 2 is a block diagram of the present utility model.
Embodiment
As shown in the figure, novel intelligent battery equalizer of the present utility model, comprise the battery pack that constitutes by two above cell E series connection, be serially connected in divider resistance R and operational amplifier IC in the cell circuit, it is the battery pack that is made of more piece cell E serial connection, in the battery pack loop, the Node B of total voltage dividing potential drop is as reference voltage, and between the adjacent monomer battery each corresponding node A as sampled voltage, this reference voltage and sampled voltage can be organized more, reference voltage and sampled voltage are inserted the positive end of oppisite phase of operational amplifier IC respectively and go into end, string has capacitor C between the positive inverting input of operational amplifier IC, and the positive-negative power termination battery supply of operational amplifier IC or charger power supply, battery supply can be the power supply of cell or the power supply of battery pack, this supply voltage can float, the output terminated nodes A of operational amplifier IC, by operational amplifier IC cell or battery pack are carried out charge or discharge, operational amplifier worker C of the present utility model adopts conventional BG305 etc.When the voltage of node A is higher than the voltage of Node B, operational amplifier IC directly discharges to the cell or the battery pack of this node by operational amplifier IC: when the voltage of working as node A is lower than Node B voltage, IC relatively judges through operational amplifier, also directly the cell E or the battery pack of this node are charged, the monomer battery voltage adjustment in the battery pack is reached balance by operational amplifier IC.
