Embodiment
The utility model is further described below in conjunction with Figure of description and specific embodiment.
As shown in figure 1, the contactor control circuit for battery of the present embodiment, include more than one group of battery control
Unit processed, each battery control unit include battery access circuit 1, battery cut-out circuit 2, Self-lock contactor 3（In figure
C1 and C2）And power supply, wherein battery access circuit 1 include access signaling interface 11, the first gating switch being sequentially connected in series
12（D1, D3 in figure）With the first auxiliary reclay 13（K1 and K3 in figure）, battery, which cuts off circuit 2, includes what is be sequentially connected in series
Shutoff signal interface 21, the second gating switch 22（D2 and D4 in figure）With the second auxiliary reclay 23（K2 and K4 in figure）,
Battery is accessed after circuit 1 cuts off the parallel connection of circuit 2 with battery to be connected with power cathode, and through the normal of the first auxiliary reclay 13
Open the closing coil 31 of contact and Self-lock contactor 3（A1 coils in figure）It is connected, and through the normal of the second auxiliary reclay 23
Open the release coil 32 of contact and Self-lock contactor 3（A2 coils in figure）It is connected, the closing coil 31 of Self-lock contactor 3 and releases
The common port of unwrapping wire circle 32（A3 in figure）It is connected with positive source.Contactor of the present utility model for battery controls electricity
Road, interlocking is realized between two coils of Self-lock contactor 3, improve the reliability of system；The output state of Self-lock contactor 3
Self-locking can be achieved, further increase reliability.
In the present embodiment, battery control unit is two groups altogether, and accesses signaling interface 11 and shutoff signal interface 21
It is two, is connected respectively with battery controller and signal terminal, the input for receiving controller or signal terminal is believed
Number.Wherein the first gating switch 12（D1 and D2 in figure）It is diode with the second gating switch 22（D3 and D4 in figure）,
For selecting the signal of controller or signal terminal, the control instruction as corresponding auxiliary reclay.When K1 coils obtain
When electric, K1 contacts 3#, 4# closure, only A1 meet 24V- and obtained electric；When K2 coils obtain electric, K2 contacts 3#, 4# closure, only A2 meets 24V-
And obtain electric.Wherein A1 coils and A2 coils can not be connected with A3 simultaneously, and after A2 coil electricities, A3 jumps to be connected with A1 coils
And self-locking, until A1 coil electricities, just A3 can be made to be connected with A2 coils, so as to realize the self-locking of output state, thus without long
Time maintains coil current, reduces coil loss, improves system effectiveness.Specifically, Self-lock contactor 3 is using C195 A
24EV-I2 models.
Touched as shown in figure 1, being in series with the normally closed of K2 in the present embodiment, between D1 the and K1 coils of battery access circuit 1
Point, K1 normally-closed contact is in series between D3 the and K2 coils of battery cut-out circuit 2, when K1 coils obtain electric, K1 contacts 1#,
2# disconnects, and K2 coils must not electricity；Equally, when K2 coils obtain electric, K1 coils must not be electric, so as to realize that two-way input signal interlocks,
Avoid malfunctioning, improve the antijamming capability of input signal, add the stability of system.
Now by taking signal terminal X1 input signal as an example, it is specifically described：
Wherein the battery access of X1 signal terminals, shutoff signal voltage are that high level is effective.When a points are low level b
For point when be high level, K2 coils obtain electric, K1 coil blackouts, and C1 A1 ends are hanging, and A2 terminates 24V-, and A2 coils obtain electric, and A3 is touched
Point（Meet DC24V+）Then it is connected with A1 coils, now C1 contact 1# and 2# closure, 3# and 4# are closed.When a is that high level b is low
During level, K1 coils obtain electric, K2 coil blackouts, and C1 A2 ends are hanging, and A1 meets 24V-, and A1 coils obtain electric, A3 contacts and A2 coils
It is connected, now C1 contact 1# and 2# is disconnected, and 3# and 5# is closed（Each contacts of C1 are used to control battery to start or disconnect）.Due to
The presence of interlock circuit, when a points are in high level, b point high level is invalid；When b points are in high level, a point high level is invalid.Cause
Can be with self-locking, a or b control instructions for C1（That is battery access signal or shutoff signal）50ms pulse signal is only needed,
Therefore the coil of Self-lock contactor 3 need not long-time keeping coil electric current.
Although the utility model is disclosed above with preferred embodiment, but it is not limited to the utility model.It is any
Those skilled in the art, in the case where not departing from technical solutions of the utility model scope, all using the disclosure above
Technology contents technical solutions of the utility model are made with many possible changes and modifications, or be revised as the equivalent of equivalent variations
Embodiment.Therefore, every content without departing from technical solutions of the utility model, according to the utility model technical spirit to real above
Any simple modifications, equivalents, and modifications that example is done are applied, all should be fallen in the range of technical solutions of the utility model protection.
