The mode of operation of the present invention is: as in figure 2 it is shown, civil power input pattern schematic diagram, when civil power is normal, automatically select
Civil power input pattern.As it is shown on figure 3, chassis electromotor input pattern schematic diagram, when city's electrical anomaly, defeated by chassis electromotor
Enter.As shown in Figure 4, energy storage battery group input pattern schematic diagram, when civil power and chassis electromotor are the most abnormal, opens immediately
Dynamic accumulator battery work.
The input of vehicle-mounted comprehensive power from alternating current 220V civil power or chassis electromotor 27V unidirectional current and accumulator battery,
Select one therein as input source by automatic logic control.When city is electrically accessed, by AC/DC component transform, access
Dc bus；When chassis electromotor inputs, it is directly accessed dc bus.Dc bus after collecting respectively by DC/AC and
DC/DC is transformed to stable alternating current 220V and direct current 24V power supply, and by the control to control panel, can finally be provided to
Equipment electricity consumption.
Hanging with energy storage battery group on the dc bus of system, when input is normal, DC bus-bar voltage is 27V simultaneously
~ 32V, accumulator battery voltage is 24V ~ 28.6V, and accumulator battery accesses bus by multiple Diode series and isolates, and stores
Set of cells the most outwards exports.When input exception, accumulator battery to bussed supply, is simultaneously entered testing circuit by diode
Judging that input is abnormal, the bypass diode actuating of relay, accumulator battery is directly connected with between dc bus, reduces loss, protects
The normal work of card.Vehicle-mounted power management system is by carrying out the voltage of branch road each in system, electric current, frequency (exchange) etc. in real time
Detection, determines work and the protected mode of the input and output of vehicle-mounted comprehensive power system.Simultaneously by reading energy-storage battery
BMS, obtains the information such as the discharge and recharge of battery, electricity, carries out discharge and recharge logic manage and state protection.
A kind of uninterrupted vehicle-mounted comprehensive power electric power system of two-output impulse generator, first, civil power is exported by AC/DC assembly
Direct current, forms dc bus, and the civil power i.e. inputted is about the high-pressure pulsating direct current of 400V by rectifier bridge and pfc circuit conversion,
By the frequency of 100kHz, MOSFET is carried out high frequency chopping again, by the transmission of isolating transformer, form low-tension pulse in secondary
Dynamic direct current, then by LC filter circuit, be transformed to meet the high accuracy 32V DC source that output requires, the topology of AC/DC assembly
Structural representation is as shown in Figure 5.
The unidirectional current that chassis electromotor sends is directly accessed dc bus, does in parallel with the dc bus of civil power output, with
Time energy storage battery group by multiple Diode series access dc bus, with diode, accumulator battery and dc bus are carried out
Isolation, in the case of making accumulator battery be operated in a cold standby, simultaneously by a bypass relay and multiple Diode series.When
When civil power and chassis electromotor normally work, the voltage of accumulator battery is 24V ~ 28.6V, and DC bus-bar voltage is 27V ~ 32V, because of
