Description
Technical field
The utility model relates to the charge in batteries repair system, the intelligent repair system of a kind of specifically storage battery complex wave.
Background technology
Along with coming into the market in a large number of electric bicycle, life of storage battery problem is more and more outstanding.Certainly, be many-sided about the problem of the life of storage battery, prolonging the life of storage battery also has several different methods.The article introduction of many this respects is also arranged before " electronics newspaper ", no longer repeat here.But the quality of charger is a very important problem always, and a good charger can effectively prolong the life of storage battery.
Through a large amount of storage batterys of scrapping of investigation, find the former of battery failure because: dehydration accounts for 80 percent, sulfuration account for 10, other account for about 10, and many batteries to be dehydration and sulfuration exist simultaneously.At this problem, drawn some experiences of forefathers, designed the intelligent repair system of a storage battery complex wave.Set up and establish temperature-compensation circuit, because of the price restriction, three common shed repairs are answered a pager's call and are not all had temperature-compensation circuit, and its constant voltage value is fixed.And according to the characteristic of lead acid accumulator, 1 ℃ of the every rising of temperature, each cell voltage just changes 4mV, and the battery temp of 48V rises 1 ℃ with regard to poor 96Mv, and rising 10 ℃ just has 1V.The constant voltage value is fixed high, and summer is dehydrations in a large number just, thus the thermal runaway of further developing, and many storage battery generation bulges of scrapping are exactly this reason.Voltage is fixed low, just might fill not enough electricity winter and causes sulfuration." electronics newspaper " had article to introduce the silicon diode of connecting summer in charge circuit in the past, and utilizing the PN junction pressure drop reduction charging voltage of diode is exactly a kind of remedial measure.Though this method is effective, does pretty troublesome.
The utility model content
The purpose of this utility model is for providing a kind of storage battery complex wave simple in structure, effective intelligent repair system.
The technical scheme that realizes the foregoing invention purpose is as follows:
The intelligent repair system of storage battery complex wave comprises power supply and control circuit, and the AC/DC circuit of described power supply adopts PWM chip UC3842, constitutes a constant voltage source with TL431 optocoupler U2, and described control circuit adopts power source special chip ZC378.
1 pin of described ZC378 chip connects battery voltage detection circuit, and described battery voltage detection circuit is made up of the R38 of high accuracy divider resistance R37.
After finishing, the 13 pin output charging positive pulse of described ZC378 chip and charging provide high frequency to repair pulse, be high level during charging, make the Q6 saturation conduction, power supply is just by the e utmost point, the P-channel field-effect transistor (PEFT) pipe conducting of 15V voltage-stabiliser tube to Q6, power supply by D10 to battery charge, 13 pin are electronegative potential when stopping, and Q6 ends, because the base stage of Q5 is+SV, so Q5 is conducting also, cause the Q4 conducting, with S, the G intereelectrode short-circuit of P-channel field-effect transistor (PEFT) pipe, Q3 also ends.
The 12 pin output discharge pulse of described ZC378 chip is high level during discharge, makes Darlington transistor Q8 conducting by R29, Q7, and power supply is just passing through high-power resistance R35 to battery discharge.
18 pin of described ZC378 chip are the temperature detection inputs.
11 pin of described ZC378 chip are the current detecting ends.
According to the contrast test to ten Battery packs, general charge repair machine has been done average 290 charge and discharge cycles, and the utility model repair system has been done the circulation more than 580 (is foundation to drop to 75% of normal capacity).
Because this circuit adopted special charging remediation management integrated circuit, have that pulse charges and discharge circuit, circuit is repaired in pulse, increased temperature-compensating again, circuit is succinct, perfect in shape and function, control precision are higher than general charger far away.During charging, the storage battery temperature rise is also very low, can effectively suppress the dehydration and the sulfuration of storage battery, also can well repair the storage battery that has vulcanized, and has prolonged the life-span of storage battery.
Description of drawings
Fig. 1 is the utility model electrical schematic diagram
Specific embodiments
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the intelligent repair system of storage battery complex wave comprises power supply and control circuit, and the AC/DC circuit of described power supply adopts PWM chip UC3842, constitutes a constant voltage source with TL431 optocoupler U2, and described control circuit adopts power source special chip ZC378." electronics newspaper " is a lot of to the power unit introduction, no longer describes in detail here.Mainly introduce the control circuit part below.
1 pin of power supply chip ZC378 is to be connected to the battery voltage detection circuit of being made up of high accuracy divider resistance R37 and R38.When detecting cell voltage and reach primary voltage 60%, enter charging procedure automatically, be lower than 60% and just enter repair procedure, if no-voltage or reversal connection then do not start.
After finishing, the 13 pin output charging positive pulse of power supply chip ZC378 and charging provide high frequency to repair pulse.The width of pulse then is the variation that needs by electric current, is high level during charging, makes the Q6 saturation conduction.Just by the e utmost point, the P-channel field-effect transistor (PEFT) pipe conducting of 15V voltage-stabiliser tube to Q6, to battery charge, 13 pin are electronegative potential to power supply to power supply when stopping by D10, Q6 ends, because the base stage of Q5 is+5V, so also conducting of Q5, cause the Q4 conducting, with S, the G intereelectrode short-circuit of P-channel field-effect transistor (PEFT) pipe, Q3 also ends.
The 12 pin output discharge pulse of power supply chip ZC378 is high level during discharge, makes Darlington transistor Q8 conducting by R29, Q7, and power supply is just passing through high-power resistance R35 to battery discharge.
18 pin of power supply chip ZC378 are temperature detection inputs, and R16 is a negative tempperature coefficient thermistor.In order to improve control precision, an ad hoc accurate reference voltage of being made up of TL431 can make precision reach one thousandth like this.
11 pin of power supply chip ZC378 are current detecting ends.Chip duty of ratio during according to detected electric current and voltage decision charging is repaired electric current thereby adjust.
6 pin of power supply chip ZC378 are fan control, only at the first two section fan running during than large current charge.
