Description
Technical field
The utility model relates to overdischarge protector for battery, relates in particular to a kind of storage battery power-off protector that prevents battery overdischarge for automobile.
Background technology
Forward engine room battery location at some automobiles adds power-off protector, to prevent under the long-time parking state of vehicle various current consumer standby power consumptions or electric leakage and discharged or defective battery phenomenon occurs, causes the vehicle cannot normal starting.And this external power-off protector not only can increase bicycle manufacturing cost, and additionally take installing space, simultaneously because himself structure problem functional reliability neither be very high.
Within open day, be that on 04 22nd, 2009, publication number are that the patent documentation of CN 201226441Y discloses the technical scheme that name is called a kind of protector for current failure of cars, its uses the devices such as radio receiver, infrared probe, switch, radio handle, wire fuse and a plurality of relays to form the power-off protection of storage battery preventing electric losses.The weak point of this technical scheme is, device used is more, causes its structure to become complicated, and from storage battery, continues power taking and extra battery consumption electric energy at the wireless device of parking state lower device itself, infrared facility, coil etc.
Summary of the invention
The utility model main purpose is to provide a kind of built-in storage battery power-off protector; storage battery power-off protection is placed in to BCM(entire car controller) management under; power-off protection apparatus structure is simplified, can effectively saves storage battery electric energy and prevent that discharged or defective battery phenomenon from occurring.
The utility model is mainly solved by following technical proposals for prior art problem, a kind of built-in storage battery power-off protector, storage battery is powered to electrical apparatus for vehicle use, comprise BCM, contactless switch and master cock, BCM comprises output relay, one normal opened contact of output relay connects respectively one end of the sucking coil of B+ and contactless switch, the other end of sucking coil is connected to the negative pole of storage battery, the normal opened contact of contactless switch is serially connected between battery negative post and the power cathode of electrical apparatus for vehicle use, BCM is by storage battery power supply, master cock connects I/O pin and the BCM power supply ground of BCM.
In this technical scheme, utilize output relay in BCM and BCM to realize the power-off protection of storage battery.Because the power supply of electrical apparatus for vehicle use is provided by storage battery, under non-power-off protection state, it is electric that BCM obtains output relay, the closed sucking coil of contactless switch of giving of output relay normal opened contact powers up, so contactless switch normal opened contact is closed, the loop that on car, the various current consumers such as starter connect storage batterys is switched on, and storage battery is in supply regular power state; While needing to disconnect storage battery after vehicle parking, press master cock, BCM obtains instruction and makes output relay power-off, its normal opened contact disconnects, so contactless switch normal opened contact disconnects, the storage battery loop that storage battery is led to each current consumer disconnects, to keep storage battery electric energy, prevent long-time parking after battery discharging cause discharged or defective battery.And this technical scheme while making parking state relay and contactless switch all without the power consumption of working coil, further saved storage battery electric energy.When needs start vehicle, need only operation control switch again, BCM will make contactless switch normal opened contact closed by output relay, so vehicle enters rapidly supply regular power state.Because BCM has the dormant state that can wake up, therefore, very low in the power consumption of parking state BCM.
As preferably, between the normal opened contact of output relay and B+, be also serially connected with relay safety plate.To strengthen the safety of control circuit.This relay safety plate (silk) is that in BCM, the relay for each output relay configuration insures.
As preferably, master cock is arranged in car on instrument carrier panel.To facilitate driver's operation.
As preferably, master cock is self-replaced type button switch.Self-replaced type button switch has simple in structure, long reliability high of life-span, and convenient operation.
As preferably, on self-replaced type button switch, be provided with LED light, LED light is connected in parallel on the working coil of output relay by current-limiting resistance.Whether LED light as the status indicator lamp in storage battery power-off protection state.
As preferably, BCM also connects a main detector switch of driving.Using the main energizing signal of an opening signal as BCM connection storage battery loop of driving; make storage battery power-off protector have more hommization and ease of use; while again opening main drive after parking, BCM connects storage battery automatically to the current supply circuit of electrical apparatus for vehicle use.
The beneficial effect that the utility model brings is; compare with the power-off protector that installs external additional; simplified circuit structure; not only reduced bicycle manufacturing cost; and take full advantage of BCM resource; make the installation of power-off protection apparatus and use all very convenient, reliable operations, and after can effectively preventing long-term parking, the external electric discharge of storage battery causes voltage below level, vehicle normal starting phenomenon to occur.
