Abstract
The utility model discloses the charger circuit of a kind of automatic identification accumulator polarity, connected an expansion output circuit by the outfan of existing charger circuit to constitute, described output circuit of expanding includes 2 diodes and 2 relays with two normally opened contacts, the diode of two groups of series connection, relay are connected in parallel on the outfan of existing charger circuit, and the coil voltage of relay is consistent with the voltage of accumulator.This utility model circuit is simple, processing ease, accumulator is connected during charging, utilize the dump energy of accumulator and the unilateral conduction of diode, make the adhesive of one of two relays, another release selectively, ensure no matter how accumulator polarity connects, and can ensure that charger is consistent with the polarity of accumulator.
Description
Technical field
This utility model relates to charger, is specifically related to the charger circuit of a kind of automatic identification accumulator polarity.
Background technology
Charger, in addition to voltage will be with the voltage matches of accumulator, also requires polarity and the accumulator of charger voltage
Polarity is consistent, i.e. both positive poles are connected with positive pole, and negative pole is connected with negative pole, and once polarity wrong will cause short circuit, makes
Become charger or battery damage.Currently, in order to prevent polarity wrong between charger and accumulator, employing following methods:
Carrying out polarity confirmation, correct wiring the most before charging, this method needs professional to operate.
2. use plug special, as electric bicycle, use isosceles triangle plug, but such charger can only be with storage
Battery regular collocation, does not the most have versatility.
Summary of the invention
The purpose of this utility model is: design the charger circuit of a kind of automatic identification accumulator polarity, to accumulator pole
Property identification automatically switch, connect, charger is not required to take into account polarity with accumulator when being connected, and is directly connected to, simple to operate, should
Charger is applicable to the charging of the consistent accumulator of all voltage, has good versatility.
Technical solution of the present utility model is: this identifies that the charger circuit of accumulator polarity is by existing charging automatically
The outfan of device circuit connects an expansion output circuit and constitutes, and described expansion output circuit includes 2 diodes and 2 tools
The relay of two normally opened contacts, the diode of two groups of series connection, relay is had to be connected in parallel on the outfan of existing charger circuit, continue
The coil voltage of electrical equipment is consistent with the voltage of accumulator.
During charging, the outfan of this charger is connected with accumulator, utilizes the electric energy of accumulator and the unidirectional of diode
Electric conductivity makes some adhesive in the middle of two relays, another release, it is achieved charger correctly connects with accumulator polarity
Connect.
The beneficial effects of the utility model are: circuit is simple, and simple to operate, during charging, charger arbitrarily connects with accumulator
Connect, it is not necessary to pay close attention to polarity or use special plug, there is accumulator polarity identification, automatic switchover, linkage function, in a word, no
How pipe accumulator polarity connects, and can ensure that charger is consistent with the polarity of accumulator, prevents from damaging because of polarity connection error
Bad charger, the versatility of charger is good.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this identifies the charger circuit of accumulator polarity by the outfan of existing charger circuit even automatically
Connect expansion output circuit to constitute, described expand output circuit include 2 diodes and 2 there are two normally opened contacts
Relay, the diode of two groups of series connection, relay be connected in parallel on the outfan of existing charger circuit, the coil voltage of relay with
The voltage of accumulator is consistent.
The model of diode D1 with D2 is identical, is 1N4007；Electromagnetic relay contain two normally opened contacts, coil voltage with
Battery tension is consistent；During charging, connect accumulator；If accumulator polarity be upper "+", lower "-", diode D1 turn on, D2
Cut-off, relay J 1 adhesive, J2 release, now two normally opened contact J1-1 and J1-2 Guan Bis of relay J 1, relay J 2
Normally opened contact J2-1 and J2-2 disconnects, make accumulator "+" pole and charger "+" pole is connected, "-" pole and charger
"-" pole connects；If accumulator polarity be upper "-", under "+", diode D2 turn on, D1 end, relay J 2 adhesive, J1 release
Putting, now two normally opened contact J2-1 and J2-2 Guan Bis of relay J 2, normally opened contact J1-1 and J1-2 of relay J 1 disconnects,
Make equally accumulator "+" pole and charger "+" pole is connected, "-" pole is connected with the "-" pole of charger.
