Embodiment: below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
A kind of single power supply formula large-capacity multifunctional field emergency electric supply installation comprises dc-battery 1 and output switches set 6; It is characterized in that: described Emergency power supply unit also comprises the two-way charge management circuit 3 that links to each other successively with described dc-battery 1, constant-voltage control circuit 4 and external equipment power-supplying circuit 5 boost; Described output switches set 6 comprises first to the 3rd dead load output switch 61 to 63 and variable load output switch 64 again.
Described dc-battery 1 comprises high-energy polymer lithium-ion electric core again; Its two ends are parallel with storage capacitor 2.It is the super capacitor of EDL473Z3R6-1 that described storage capacitor 2 adopts model.This electric capacity has extremely low leakage current, extremely strong energy pulse absorbability and ultralow series impedance, and also capacity is very big, reaches 47mF, and storage power is standby for a long time after the charging.In establish barrier film, become polarity free capacitor, the convenient use.
Described multi-functional field emergency electric supply installation also comprises application load 7; This application load 7 comprises illumination torch 71, purple light currency examine lamp 72 and laser pointer lamp 73 again.
Described field emergency electric supply installation shell is provided with fastening plug-in function load socket 74.
It is the integrated pressure limiting circuit of S-8261 and the integrated current-limiting circuit that model is SI6968 that described two-way charge management circuit 3 adopts model.
In the practicality, external charging round pin receptacle 8 is arranged on the shell of this device and accept charging round pin receptacle 9; Comprise dead load output switch 61,62,63 and variable load output switch 64 in the output switches set 6; Be provided with a master switch 12.Comprise a high brightness flashlight 71, a ultraviolet currency examine lamp 72 and a laser head 73 in the application load 7, and fastening plug-in functional module is with dovetail groove type universal contact receptacle 74.
Main electric core 1 is housed, storage capacitor 2 and main electric core management of charging and discharging and plug-in module management circuit in the casing.This power supply can disconnect master switch 12 after being full of electricity, and all circuit and electric core disconnect, and makes electric core and ultracapacitor be in the relative static conditions of unmatchful outer output, reduces no-load loss, prolongs the standby time.
When needs are powered to power consumption equipment with this machine, master switch 12 need only be connected, and both can by corresponding switch.For example; When master switch 12 is connected the back as if using flashlight, it is promptly bright to press flashlight switch 61 flashlights, if it is promptly bright to press currency examine switch 62 currency examine lamps, in like manner promptly bright by dead load output switch 63 laser heads, if plug plug-in module 74, press variable load output switch 64 and can give plug-in module for power supply.When switch 12 disconnected, electric core 1 was in released state fully with external circuit, guarantees that electric core is lossless.
