Embodiment
Below in conjunction with accompanying drawing to this practical being described further.
As shown in Figure 1, a kind of discharging process of automobile battery management circuit structure of the present utility model, it comprises storage battery B1, double-point double-throw switch K1, vehicular electrical appliance, car body controller, control switch, capacitor C 1, positive-negative-positive triode Q1, NPN type triode Q2, the first switching diode D1, second switch diode D2 and pull-up resistor R1.This double-point double-throw switch K1 is that two single-pole double-throw switch (SPDT)s form side by side, each single-pole double-throw switch (SPDT) all has three contacts, comprise a normally opened contact, a normally-closed contact and a common, the first single-pole double-throw switch (SPDT) has the first normally opened contact, and the first normally-closed contact and the first common are corresponding, the second single-pole double-throw switch (SPDT) has the second normally opened contact, the second normally-closed contact and the second common.Described car body controller (MCU) is preferably single-chip microcomputer, and described control switch is relay switch.
The connected mode of each device is: the described control switch of connecting between the positive pole of storage battery B1 and the positive pole of vehicular electrical appliance, the negative pole of storage battery B1 and vehicular electrical appliance is ground connection respectively, the first common of described double-point double-throw switch K1 is connected with the positive pole of storage battery B1, and the second common is connected with the negative pole of storage battery B1 by capacitor C 1.
The emitter of positive-negative-positive triode Q1 is connected with the first normally opened contact of double-point double-throw switch K1, collector electrode is connected with the Vcc end of described car body controller, base stage is connected with the collector electrode of described NPN type triode Q2, between the emitter of this positive-negative-positive triode Q1 and the base stage and be connected to described pull-up resistor R1.
The base stage of NPN type triode Q2 is connected with the second normally opened contact of double-point double-throw switch K1 by described the first switching diode D1, grounded emitter, the base stage of this NPN type triode Q2 also is connected with the level output end P1 of described car body controller by described second switch diode D2, and this first switching diode D1 is connected negative pole (negative sense) and is connected with the base stage of described NPN type triode Q2 respectively with second switch diode D2.
