Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment:
The electric supply system of mobile power vehicle, as shown in Figure 1, comprise vehicle mounted dynamic battery system and inverter U, vehicle mounted dynamic battery system comprises electrokinetic cell P, and the mouth of electrokinetic cell P and the input end (72V+, 72V-) of inverter connect, output (the N of inverter, L) as the output of electric supply system, the electric energy of 220V2000W is exported; The direct supply that described electrokinetic cell P exports is high-voltage DC power supply, and the voltage magnitude of high-voltage DC power supply is more than or equal to 72V, and the output rating horsepower of described inverter is 2000W.
The direct current power source voltage that electrokinetic cell exports, for being more than or equal to 72V, because the mouth of electrokinetic cell is connected with the input end of inverter, therefore, increasing the direct current power source voltage that electrokinetic cell exports, namely increases the voltage of inverter input terminal input.Inverter, under same power stage condition, increases the voltage of input end input, just can reduce received current, and reduce the risk that inverter input big current brings, safety is high.And the Power Limitation that orthodox car inverter output power is subject to automotive wire bundle and electrical generator exports rating horsepower generally about 700W (being powered by automobile cigarette lighter), the horsepower output of the electric supply system of car load is less, input current of inverter is very large, likely causes vehicle body circuit or insurance to damage.Carrying out also needing in power supply process to be kept by driving engine tickover to prevent storage battery power shortage in addition.And the electric supply system actv. of the present embodiment make use of the advantage of electronlmobil, not only inverter is exported rating horsepower and accomplished 2000W, and vehicle can not consume gasoline as fuel vehicle in the process using inverter, has energy-saving effect.This electric supply system received current under equal-wattage exports is traditional 1/6th, greatly reduces the circuit superheat that big current causes.Additionally use pure wave simultaneously and export (the same with general household electric), avoid the injury of correction waveform to electric equipment products of general inverter.The high-performance pure sinusoid of electric supply system 2000W exports the household electrical appliance demand solving 90%, can meet the use of domestic electric appliance on mobile power vehicle.During concrete enforcement, inverter preferably selects inner increase to have the circuit of the function such as electrocution-proof protection and under-voltage protection, can effectively prevent battery supply feed and use safety like this.Under described inverter is arranged on cab seat or other concealed locations of vehicle body.Inverter and vehicle body are arranged hidden, avoid children from getting electric shock danger, and be positioned over operator's compartment relative to orthodox car inverter safer, overall circuit incorporates overall wire sheaves.
Conveniently chaufeur checks the mode of operation of power-supplying circuit, the pin 3,4,5 of inverter U can also be connected with LED respectively, like this when occur under-voltage, overload, short circuit, overvoltage, energy content of battery deficiency and excess temperature time, LED is lighted, and facilitates chaufeur to check.
The supply vehicle that this electric supply system is housed can be outdoor study personnel provides power supply, the equipment such as refrigerator and micro-wave oven that simultaneously can be equipped with onboard provides the life of more high-quality for operating personnel out of doors, more convenient safe power supply is provided simultaneously, electric light can be equipped with onboard, electric heater and various electric cooking utensils and acoustical equipment.
In order to avoid energy dissipation, hommization and convenience more.Also comprise relay K 2 and master cock K1; One end of master cock K1 is connected to bodywork system ACC shelves ACC, and the other end is by series LED lamp ground connection, and the one end be connected with LED in master cock is connected with one end of relay coil, the other end ground connection of relay coil; Two tip sides of relay K 2 are connected on the high pressure control end (U pin 6,7) of described inverter respectively.
Like this, just can by the mode of operation of master cock and bodywork system ACC shelves co-controlling inverter.Bodywork system ACC shelves provide power supply for master cock.When automobile ACC gear is pressed, and when master cock is pressed, master cock conducting, relay coil is energized, and relay two moving contact end closes, and trigger inverter starts.When master cock is not pressed or bodywork system ACC shelves do not start, master cock not conducting, relay coil no power, inverter does not start.Like this when inverter closed by needs, but when forgetting closing control switch, inverter can stop exporting along with taking off of car key automatically.
In order to improve the safety of electric supply system further, reduce the risk that electrokinetic cell output overloading produces.Also comprise wire fuse FD1, wire fuse FD1 is connected in the input circuit of described inverter.The electric current exported when electrokinetic cell is excessive, and when namely the electric current of inverter input is excessive, wire fuse disconnects, protection inverter circuit below.
