Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of Outfield special constant-current power compensating device for model airplane battery.
Background technology
At present, the charger that is used for rechargeable battery on the market is of a great variety, the charging technique that charger is used is nothing more than several modes such as unsteady flow level pressure, variable voltage and variable current, pulsed, constant current level pressure are arranged, but all charging devices are full of the back in case break away from charging device at the electric weight of rechargeable battery, the voltage of rechargeable battery will be pressed with falling of certain amplitude than the peak electricity in online when charging, and its reason mainly is so that rechargeable battery is the caused negative effect of self-discharge phenomenon that has.General charging device generally can't be in the face of the existence of this problem in design and use; this part very valuable, explosive bigger energy of rechargeable battery crest voltage (electric weight) is left in the basket always; these are with the electric weight of self discharge mode loss; people generally believe that this some point electric weight of loss is insignificant; be exactly on the daily workout or match of model plane activity; this problem does not obtain paying attention to all the time yet, is existing mistaken ideas aspect the use of rechargeable battery always yet, and main phenomenon is:
1, do not work hard on the characteristic of understanding and heightened awareness rechargeable battery, and use the charging device of the low common rectifier power source of charging effect as rechargeable battery for a long time, the performance of rechargeable battery (electric weight) constantly is subjected to serious, irreversible influence;
2, many schools or student pursue purchase blindly, simply, use big capacity rechargeable battery.With regard to reality, no matter be peacetime training or the various model plane competitions of participation, the amount of capacity of rechargeable battery has not been a subject matter, the not handy key of rechargeable battery is to work hard aspect the correct operation and maintenance of rechargeable battery;
3, common typical practice is charged at the indoor rechargeable battery of giving last night, just is directly used in the participation model plane competition in second day.
More than all ways, in model plane competition, generally be difficult to obtain outstanding achievement as power with rechargeable battery.
Movable or the participation model plane competition in the outfield, the operation and maintenance aspect of rechargeable battery must be accomplished: at first be that the performance of rechargeable battery own will be got well, must not there be inadequate natural endowment (certain electronic model plane are also necessary through certain technological transformation) in the model plane various aspects of performance; The 2nd, adhere to using the charging device that helps bringing into play NI-G, nickel-hydrogen chargeable cell superior function; The 3rd, most critical work is promptly used constant current to mend electric installation in pre-games the model plane electrokinetic cell is mended.
When participating in that model plane are competed for speed or left a blank and wait campaign item or competing, the purpose of the model plane electrokinetic cell being mended electricity is exactly to want fully, effectively utilize the explosive bigger energy of that part, electronic model plane are just displayed just can gain the initiative rapidly, when cell voltage to be charged (electric weight) dropped into common state, your model plane were stood high above the masses or are taken the lead preceding.
In being suitable on the market, the charging device that uses of the training of primary school's model plane activity and outfield or model plane competition is difficult to seek.

Using method
1, empirical equation: T=(1.3～1.6) C/I (T is the charging interval, and 1.3～1.6 is time coefficient, and C is the rechargeable battery capacity, and I is a charging current) commonly used.During charging, after rechargeable battery capacity, performance (newness degree) select time coefficient and charging current, easily determine the charging interval, as: charge for the 900mAH Ni-Cd nickel-cadmium indoor, time coefficient selects 1.5, then: T (charging interval)=1.5 * 900mAH/300mA=4.5 hour
In general, the battery of the older or poor-performing of rechargeable battery, time coefficient should be selected greatly.Mend electricity in the outfield for the model plane electrokinetic cell or under the situation of usefulness such as anxious, should select the little electric current of slow shelves to mend electric mode and help to fill rechargeable battery full, and be difficult for generating heat and damage rechargeable battery;
2, before indoor charging, for eliminating the remaining electric weight of memory rechargeable battery set and should discharge (general per 5 circulations of Ni-Cr battery, per 10 circulations of Ni-MH battery will fully be discharged 1 time, will note rechargeable battery balanced discharge problem simultaneously) by standard.When discharging current was 300mA, the final voltage of rechargeable battery bringing onto load discharge was 0.85～0.90V;
3, when mending electricity at a slow speed, every joint rechargeable battery control voltage is 1.58V (mending electric installation does not have design to be full of automatic stopping circuit, and the most handy digital voltmeter monitors during use, to prevent excessive benefit);
4, generally be controlled at 10～25 minutes in the outfield benefit electricity time, stopped to mend in last 1～2 minute that grasps before starting the clock;
5, when match can not the unsettled brand-new rechargeable battery of serviceability, more can not use rechargeable battery too old or that performance is too poor, and new and old rechargeable battery can't be used with;
6, be 5 joints or the following rechargeable battery of 5 joints when mending electricity, because of the voltage difference at three end adjustable voltage-regulating ic piece two ends produces more heat greatly, all will pay special attention to mend the ventilation and the heat radiation of electric installation, and benefit will be avoided the sun direct projection when electric.
