Abstract
The invention relates to a direct current charger which is formed by series connection of voltage drops of a plurality of diodes, and different battery chargers can be produced according to different characteristics of various batteries.
Description
Technical field
Battery charger
Background technology
After having had battery appearance, the mankind are just carrying out research, more various battery being developed in succession is had to create, particularly the appearance of circulation rechargeable battery is subject to more user and accepts and the selection of more multiple-purpose electric appliance, but there is chargeable battery, charger and charger just become the essential breath of life of user, but present most charger is all that alternating current 220V power supply is used, what must have along with the different people of various conditional request is operated in the local work or life that do not have alternating current, in other words conj.or perhaps along with the use of newborn energy solar energy, all need to take DC power supply as mobile phone or various emergency light with the people when interruption maintenance, the chargings such as flashlight.So DC charger has been indispensable a kind of charger.
Summary of the invention
One is used in DC power supply charger, its feature: the voltage that the voltage drop of produce with the one-way conduction of some semiconductor diodes 0.6 to 0.7 is applicable to required for rechargeable battery to be concatenated into output voltage, charges as to rechargeable battery.
Now general take direct current as the large to there being two schemes of rechargeable battery, and a kind of is again with being applicable to charging the battery of AC charger after boosting with direct current, and another kind is that direct resistance is to do step-down to being charged by rechargeable battery.
But two kinds of above modes all also exist certain defect, and power boost is become High Level AC Voltage, be that booster system compares power consumption on the one hand, be on the one hand the voltage exchanged and frequency not necessarily just and former AC charger coupling; Resistance step-down directly makes DC charger, and it just also exists not only voltage drop loss, also has electric current also along with the pressure drop loss of voltage is on resistance.
So the charger be extremely concatenated into two, it only also exists voltage drop, and there is no electric current along with the shortcoming of loss, thus overcome the shortcoming that charging current can not meet the long grade of the charging interval by rechargeable battery, just can see the size of rechargeable battery and select great diode to make the charger of certain rechargeable battery demand applicable.
Accompanying drawing illustrates:
Figure is the line map of charger.
Embodiment
In general the voltage of charger must higher than can be carried out its charging by the voltage of rechargeable battery, but some batteries are not that the voltage of requirement very strict or perhaps high second of the three ten-day periods of the hot season is without feared to charging voltage, with regard to by lead accumulator, like this he is exactly, some rechargeable batteries will be strict the charging voltage of requirement charger only permit it within the specific limits, that is there is the charging voltage of standard, this voltage mustn't be exceeded, it is exactly to be used in now on mobile phone and lithium ion battery on laptop computer, various Ni-Cd nickel-cadmium and nickel-hydrogen chargeable cell etc. is also had all to require very strict to charging voltage, also want corresponding consideration to use to fill that battery and manufacture so select diode to make charger.
Now just do charge power supply with 12V DC battery jar, if give the lithium cell charging of 3.7V! the resistance step-down that existing market uses is to make charger, the resistance of resistance the chances are about 40 Ω, will with the silicon type semiconductor diode of about ten with diode, the silicone tube of will to measure the single pressure drop seeing diode when manufacturing be how many volt, every 0.7V is just with ten in this way, 0.6V just uses 11 in this way, this just charges to the battery of the external circuit with protective device, its charging voltage is 5V, directly receive on battery separately in this way, its charging voltage is about 4.2V, that just must increase the many diodes of series connection, because also there is overcharge protection circuit in the general battery of lithium battery itself, license is floated in the scope of a few volt at zero point, but must not exceed voltage voltage in rated voltage.
If made, lead accumulator is charged, just can relax the voltage of restriction, charging voltage can exceed by several volts of rechargeable battery, and the large storage battery of such as 12V, to the little storage battery charging of 6V, needs the diode six of pressure drop 0.7V just passable, the voltage drop that the Diode series of six rises is for 4.2V, also have the charging voltage of 8V nearly to charge to it, the little storage battery of 4V in this way, diode just can increase string to nine, series connection pressure drop is 6.3V, also has 6V voltage nearly to charge to it.
