Description

The balanced charging method of batteries
Technical field
The present invention relates to the storage battery class, specifically is a kind of balanced charging method of batteries.
Background technology
Storage battery is the energy carrier of electric motor car, is the critical component that influences electric vehicle performance." storage battery be not damage but fill bad " this saying is not sensationalism, the quality of charge in batteries performance plays a part very important to the useful life and the serviceability of storage battery.At present, the lead-acid batteries that is widely used in electric bicycle, electro-tricycle, electric automobile etc. all adopts the mode of serial connection charge, discharge, circuit connects simple, being about to the positive pole of a batteries and the negative pole of another batteries links together, distinguish lead-out wire from the anode and cathode terminals of remainder again, can link to each other with charger or the corresponding terminals of electric vehicle power sources line, so just constitute power circuit.Yet there are many deficiencies in the batteries serial connection charge, particularly causes single battery voltage to fall behind easily, and then make batteries bulk supply ability drop, even lost efficacy, at this moment can only replace the inefficacy single battery and recover its normal power supply ability by batteries is safeguarded.At present, the harmony of series connection batteries still is a global difficult problem, always has " backwardness " storage battery in the use and exists.Its reason is diversified, and the reason of production reason, raw material reason and use etc. is arranged.This just need carry out equalizing charge to storage battery, the phenomenon of its single-unit storage battery " backwardness " is improved or eliminates, and to guarantee each batteries of batteries comparatively desirable consistency is arranged, and then prolongs storage battery useful life, reduces the electric motor car use cost.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, thereby provide a kind of each batteries of batteries that can effectively guarantee to have comparatively desirable consistency to prolong the balanced charging method of the batteries in batteries useful life.
Technical scheme of the present invention is as follows:
A kind of balanced charging method of batteries is characterized in that: each batteries of batteries adopts discharged in series, provides high voltage to power to electric motor car; Adopt charged in parallel, promptly all positive poles of batteries are linked together, all negative poles link together, draw the corresponding terminals with charger of wiring from positive and negative polarities respectively again and be connected, make the battery charging equilibrium, batteries of the present invention connects electromagnetic type relay, batteries connection in series-parallel conversion is controlled by electromagnetic type relay, when electric vehicle power sources was connected, batteries converted series system automatically to, for electric motor car provides power supply; When electric vehicle power sources disconnected, batteries converted parallel way automatically to.
Batteries of the present invention is connected with equalizing resistance between each storage battery, under off-position, be in paralleling model, and when batteries left standstill or charge, the electric charge that is undertaken between battery by equilibrium between each storage battery was moved, and reached the balance of storage battery.
The present invention has adopted electromagnetic type relay control, effectively realizes the connection in series-parallel conversion of each battery between batteries, both can provide the required battery of batteries charging equalizing charge mode in parallel, can be exchanged into the discharged in series connected mode again and travels used for electric motor car at ordinary times.There is comparatively desirable consistency to prolong batteries useful life thereby the present invention can effectively guarantee each batteries of batteries, has efficient height, with low cost, characteristics that power consumption is little.
Description of drawings
Fig. 1 is the embodiment change-over circuit schematic diagram of 24V charged in parallel, 48V discharged in series.
Fig. 2 is the embodiment change-over circuit schematic diagram of 12V charged in parallel, 48V discharged in series.
Execution mode
Embodiment 1 24V charged in parallel, 48V discharged in series circuit
Fig. 1 is 24V charged in parallel, 48V discharged in series change-over circuit schematic diagram.When Closing Switch K, electromagnetic type relay J moving contact 2,5,8 is under the suction-operated of the electromagnetic force that coil produces, disconnect with normally-closed contact 3,6,9 respectively, simultaneously respectively with normally opened contact 1,4,7 adhesives, circuit conversion is four joint 12V12Ah storage battery E1, E2, E3, E4 series connection, i.e. 48V discharged in series circuit connecting mode; When cut-off switch K, relay moving contact 2,5,8 just disconnects with normally opened contact 1,4,7 respectively, simultaneously respectively with normally-closed contact 3,6,9 adhesives, circuit transfers E1 to E2, E3 and E4 is first connects, again the 24V charged in parallel circuit connecting mode of big parallel connection.
Resistance R is an equalizing resistance, plays the effect of balanced two batteries in parallel connection group voltage differences in the charged in parallel circuit.In the ideal case, promptly all storage batterys do not have difference, and we can think does not have electric current to flow through on the R, and the access of R does not influence the operate as normal of entire circuit so.Under actual conditions, each single-unit storage battery is the property of there are differences always, and after repeatedly recycling, the voltage differences of single-unit storage battery can highlight gradually.Adopt the charged in parallel circuit connecting mode difference voltage can be transferred to the two ends of resistance R, make the batteries in parallel connection both end voltage always be in equal state, thereby slackened voltage differences between single-unit, the balanced well difference of whole battery group.
Embodiment 2 12V charged in parallels, 48V discharged in series circuit
Different with embodiment 1 string and circuit is that this circuit adopts the conversion of realization from the 12V parallel circuits to the 48V series circuit synchronously of two relays.
As shown in Figure 2, circuit is complicated slightly than embodiment 1, and its principle is closely similar, all adopts the characteristics of relay sound contact normally-open normally-close.Two electromagnetic type relay J1, J2 connect together, and control its synchronization action with a K switch.When moving contact 2,5,8 and normally opened contact 1,4,7 adhesives, circuit is a 48V discharged in series road connected mode; When moving point and normally-closed contact 3,6,9 adhesives, transfer 12V charged in parallel circuit to.
The R equalizing resistance is connected in the 12V charged in parallel road, when single battery voltage backwardness appears in battery pack, equalizing resistance R has reached the purpose of each batteries voltage differences of balance just with part difference voltage equilibrium treatment in addition, guarantees that whole group storage battery has comparatively desirable consistency.
Generally speaking, above-mentioned two kinds of embodiment serial-parallel conversion circuit structures all adopt relay normally open normally closed switch characteristic, and the characteristics of equalizing resistance R transfer voltage difference, both reached the requirement of changing between discharged in series and the charged in parallel circuit, solved the consistency problem between each batteries of batteries again, the present invention can adopt 12V, 24V respectively, 32V, the 36V charger carries out charged in parallel to batteries.
The present invention has adopted a kind of brand-new equalizing charge mode in parallel, and to reach the purpose that repeatedly recycles, equalizing charge in parallel has improved the drawback of storage battery serial connection charge deficiency in the past greatly.Can be widely used in fields such as electric bicycle, electro-tricycle, electric automobile and mixed power electric car.
