Description
Technical field
The present invention relates to a kind of fuel cell and the control system and control method of lithium battery interactive mode power supply.
Background technology
At present, when using the energy, the energy is non-renewable, can also trigger environmental issue, limits new energy and quickly sends out
Exhibition.However, the new energy of different technologies route, the segmenting market to apply in difference there is limitation：Such as, wind-force and light generate electricity by certainly
Right conditionality, and it is suitable only for stationary applica-tions application；Lithium ion battery is only capable of being adapted to small-sized movable due to its energy density problem
Formula power supply application.The development of new-energy automobile and unmanned plane proposes higher requirement to driving power supply, and lithium ion battery is made
Applied for new energy power on passenger car and unmanned plane, the course continuation mileage of vehicle is general between 1 hundred to two hundred kilometer, nobody
The machine flight time, as driving power substantially " awkward ", new driving power supply short slab showed lithium ion battery less than 30 minutes
And be clear to.
Currently, optional driving electrical source of power mainly has lithium ion battery and fuel cell.Lithium ion battery exports peak value
Power is higher and dynamic response is fast；Fuel battery energy metric density is high, can firm power output.Fuel cell and lithium ion battery knot
Application is closed, hybrid power system is constituted, the energy that fuel cell makes up lithium ion battery is not enough, lithium ion battery makes up fuel electricity
Not enough, hybrid power is obviously improved the cruise-ability and mobility of driving power to pond instantaneous power.
Power supply is constituted as mixing, energy supplement type is made, there is power supplement type.
Energy supplement type；Power is driven based on lithium ion battery, fuel cell supplements electricity for lithium ion battery in good time
（Suitable mobile phone charge pal）Claim to increase journey pattern；In configuration, relatively low configuration fuel cell rated output power contributes to reduction to fire
Expect battery deployment cost, such as long-time output-constant operation then " power hardly possible and ".
Power supplement type；Power is driven based on fuel cell, when bearing power is increased, beyond fuel cell rated output
When, lithium ion battery supplements to load and provides power；Because lithium ion battery has big multiplying power discharging ability, in short time big work(
Rate is quick afterwards to supplement to load discharge, in case subsequent power is supplemented；It can be advantageously reduced using the configuration of low lithium ion battery
Overall operation cost.In case of lasting high-power applications then show power " embarrassment ".
The content of the invention
