Background technique
Battery has voltage stabilization, power supply reliable, is widely used in power plant, communication system, electric car, aviation
Each department such as space flight, vessel traffic.In numerous areas, the main effect of battery as startup power supply first is that use；Two
It is to be used as backup power source.
Since existing accumulator charging/discharging system is only completed to carry out battery group charging and standby battery group
Conversion.It cannot play and battery group is effectively managed, managing and maintaining for battery group also needs to come by operator
It completes, so Shortcomings: one, charging/discharging apparatus uses centralized control, and the distance due to equipment away from battery group is differed, filled
Line loss causes the inconsistent of charging voltage when electric, directly influences the charging quality to battery group；Two, since equipment is set
Fixed over-discharge point is lower, cannot charge in time to battery group after conversion, and battery is in power shortage state and deep discharge
The time of state is longer；Three, equipment is unable to the use state of dynamically track battery, under artificial intervention, it is difficult to ensure that storing
The service life of battery；Four, the volume of equipment and power consumption are excessive, and aboard ship in the case of limited power, excessively high loss can add
The burden of ponderomotive force system wastes limited power resource.Five, battery is a kind of extremely complex equipment, to temperature requirement
It is higher, temperature-compensating must be carried out to the charging of battery, guarantee within the scope of very wide temperature, battery can be made just sufficient
Electricity, without generating charge less and overcharging.
Space probe proposes high reliability and efficient requirement to battery group charge/discharge control circuit.
Summary of the invention
The present invention is to mention under space probe high reliability, high efficiency requirement background to battery group charge/discharge control circuit
A kind of solution out, the present invention provides a kind of control methods of the electric discharge group ladder of multiple signals synchronizing function work.
A kind of control method of the electric discharge group ladder work of multiple signals synchronizing function, step 1: 1 tunnel of selection control letter
Number, negate the complementary signal group for realizing 100% duty ratio；Step 2: complementary signal group controls electric discharge group circuit, realizes electric discharge group
Two-way discharge circuit alternating, complementary work inside circuit；The discharge circuit that alternating, complementary puts control realizes low-power consumption work；Step
Three: discharge current I, as I1 < I < I2, ENB1 set, electric discharge group (1) work；As I2 < I < I3, ENB1, ENB2 set,
Electric discharge group (1), (2) work at the same time；As I3 < I < IMAX, ENB1, ENB2, ENB3 set, electric discharge group (1), (2), (3) are simultaneously
Work.
Preferably, electric discharge group described in step 2 is made of two-way discharge circuit, and complementary control signal controls electric discharge respectively
Two-way discharge circuit in group, the two-way discharge circuit phase difference are 90 °, the transformation of two-way discharge circuit in the electric discharge group
Device and mutual inductor Coupled Magnetic Path are mutually orthogonal, least in power-consuming, it may be assumed that
T=2 Ω fI2L=2 Ω fL (I1+I2)2=2 Ω fL (I1 2+I2 2+2I1*I2Ω fL (the I of)=21 2+I2 2)
Preferably, the control of 1 tunnel described in step 1 signal has redundant backup function.
The present invention is to control signal multiselect 1, and when certain is all the way or under a few roads control signal fault, still can select 1 tunnel can
The control signal leaned on realizes and obtains reliable synchronization signal under conditions of controlling the redundancy backup of signal, and synchronization signal takes
Anti- to obtain complementary signal group, to control discharge circuit, wherein complementary control signal duty ratio and 100%, realizes control electric discharge
The loss of group is minimum.
