Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described.
It is a kind of dual power supply Emergency power supply unit described in the utility model as shown in Figure 1, comprises main battery 1, reserve battery 2, circuit controller 3 and hand switch S1; Described main battery 1 is provided with main positive terminal 11 and main negative terminal 12; Described main positive terminal 11 and main negative terminal 12 are connected with circuit controller 3; Described reserve battery 2 is provided with standby positive terminal 21 and standby negative terminal 22; Described standby positive terminal 21 and standby negative terminal 22 are connected with circuit controller 3; Described main positive terminal 11 is connected with standby positive terminal 21, and 12 main negative terminals are connected with standby negative terminal 22; Being provided with hand switch S1, hand switch S1 on described reserve battery 2 and control the unlatching of reserve battery, hand switch S1 place is provided with switch protective cover 4; Described circuit controller 3 includes charging current detecting device 31, closes standby battery device 32 and reserve battery enables device 33; Described main battery 1 uses diode-isolated D1 with reserve battery 2.
Main battery 1 and reserve battery 2 are charged by automobile current generator by circuit controller 3 under normal circumstances, circuit controller 3 detects main battery 1 in real time and is in charging or discharge condition, if being in charged state to illustrate that automobile is started successfully, now hand switch S1 is in path or off state all will be switched off automatically, and reserve battery 2 cannot externally be powered, when main battery 1 cannot normal operation time, hand switch S1 button on manual unlocking reserve battery 2, now reserve battery 2 is to circuit regular picture, each components and parts can normal operation within a period of time, open the startup power supply of car, the startup motor work strip electrical automobile electromotor operating of car, driving automobile electrical power generators after automobile engine normal operation, when charging current detecting device 31 detects charged state, hand switch S1 button on reserve battery 2 disconnects automatically, now reserve battery 2 no longer supplying power for outside, circuit transfers to automobile current generator be powered with main battery 1, when there being dump energy to main battery and reserve battery charging.
As shown in Figure 2, described charging current detecting device 31 includes coupling electric capacity C1, operational amplifier U1A and resistance R1, R2, R3; Described closedown standby battery device 32 includes charged state relay K 2, and including relay coil K2A and electrical equipment normally-closed contact K2B, sustained diode 2, relay drives audion V1 and audion current-limiting resistance R4; Described reserve battery enables device 33 and includes reserve battery and enable relay K 1, including relay coil K1A, relay normally open contact K1B and relay normally open contact K1C.
I is charging current and direction, and charging current is amplified the after-applied magnitude of voltage driven in audion V1 base stage at relay by Va, and Vm is the magnitude of voltage of main battery, and Vb is the magnitude of voltage on reserve battery; When automobile normally starts, automobile current generator charges to main battery 1 and reserve battery 2 simultaneously, when rechargeable battery reaches certain value, the value of Va is enough to drive relay to drive audion V1 conducting, charged state relay K 2 relay coil K2A is energized, and the electrical equipment normally-closed contact K2B of charged state relay K 2 disconnects; When car engine is not opened, without charging current, now the magnitude of voltage of Va is 0V, and relay drives audion V1 cut-off, and charged state relay K 2 relay coil K2A no power, the electrical equipment normally-closed contact K2B of charged state relay K 2 remains closed.
Main battery 1 is under-voltage cause normally can not starting car engine time, now without charging current, charged state relay K 2 not electric, electrical equipment normally-closed contact K2B remains closed, manually press hand switch S1, reserve battery enables relay K 1 and obtains electric, relay normally open contact K1B closes, relay normally open contact K1C closes, reserve battery 2 enables relay K 1 and is in self-locking state, reserve battery 2 is in use state, when starting after successfully, automobile current generator charges to main battery 1, when electric current reaches certain value, charged state relay K 2 obtains electric, electrical equipment normally-closed contact K2B disconnects, reserve battery enables relay K 1 dead electricity, relay normally open contact K1B disconnects, main battery 1 and reserve battery 2 disconnect, it is in passive charged state.
