Technical field
The present invention relates to a kind of hybrid motor vehicle energy storage device and utilize this device energy amount adjustment method.
Background technology
When drive a vehicle in the city, because red light and crowded traffic, the operating mode that loiters is used the energy of the locomotive nearly 30% of combustion engine to be converted into heat in braking and is lost in the environment.And energy cost day by day increases on the one hand; the environmental protection cry is surging successively on the other hand; so it is imperative that the energy of waste is stored; oil and electricity hybrid vehicle utilizes the mode that increases energy storage system to reclaim braking energy just, auxiliary internal combustion engine drive when can or quicken in climbing simultaneously.
Conventional storage battery (lead-acid storage battery, nickel-hydrogen accumulator etc.) is adopted in the energy storage of oil electric mixed dynamic automobile.Conventional storage battery can provide big electric current in long time range, but it is very responsive to situations such as big ripple, deep discharges, even under the working cycle of full charging, threshold currents discharge and equalizing charge, it also can only arrive several thousand times by the repeated charge hundreds of, and cycle life is short.In addition, the power density of conventional storage battery is very little.Because the process of accumulator cell charging and discharging is a chemical reaction process slowly, and the time of automobile brake is very short, is not enough to a large amount of braking energys is stored, energy recovery efficiency on the lower side.In addition, when automobile climbing, acceleration or startup, require the bigger electric current of the instantaneous conveying of energy storage units, this can not be competent at for conventional battery pack, the assistive drive poor performance.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of hybrid motor vehicle energy storage device and utilizes this device energy amount adjustment method, makes that the hybrid motor vehicle energy storage device power density is big, and the life-span is long.
Realize technical scheme of the present invention:

Also have capacitor bank, be connected to DC-to-DC converter between capacitor bank and the battery pack;
Also have inverter, inverter is electrically connected with battery pack, DC-to-DC converter, motor respectively;
Also have battery management unit, can control DC-to-DC converter according to voltage, the current value of battery pack and capacitor bank.
2, a kind of above-mentioned hybrid motor vehicle energy storage device carries out the energy amount adjustment method, it is characterized in that: entire car controller judges according to vehicle speed signal, throttle signal and brake pedal signal that automobile is in braking or during deceleration regime, signal is sent to battery management unit, enter the regenerative brake pattern, battery management unit is controlled DC-to-DC converter according to voltage, the current value of battery pack and capacitor bank, and the motor that is operated in generator mode is charged to battery pack, capacitor bank through inverter.
The beneficial effect that the present invention has:
Because capacitor bank absorbs the energy of automobile regenerative brake feedback, has avoided the injury of frequent high current charge-discharge to battery pack.Because the capacitor bank long service life, thus the life-span of energy storage system obtain prolonging.Because capacitor bank has good big current delivery ability and capacitor bank and main storage battery group can carry out transformation of energy, capacitor bank voltage also is adjustable to required voltage, the efficient that regenerating braking energy is reclaimed is greatly improved, cold start becomes more reliable simultaneously, cranking time shortens, pick-up time shortens, and discharging also improves.
Description of drawings
Fig. 1 is for realizing structured flowchart of the present invention;
Fig. 2 is the structural representation of energy storage area.
The specific embodiment
As shown in Figure 1 and Figure 2, be connected to DC-to-DC converter between capacitor bank and the battery pack; Inverter is electrically connected with battery pack, DC-to-DC converter, motor respectively, and motor is connected with engine mechanical; Battery management unit (BMS) can be controlled DC-to-DC converter according to voltage, the current value of battery pack and capacitor bank, and promptly battery management unit is operated to carry out buck or boost by PWM (pulse width modulation) ripple control DC-to-DC converter (DC-DC).
Be provided with K switch between battery pack and DC-to-DC converter and the inverter, this switch is controlled by battery management unit.Battery management unit makes the K switch correc operation according to the magnitude of voltage of battery pack SOC and capacitor bank.When battery pack can not discharge and recharge, off switch.
Motor control unit MCU control motor carries out electric model or power generation mode, and engine management system EMS controls driving engine.
1, regenerative brake pattern
Entire car controller (HCU) judges according to vehicle speed signal, throttle signal and brake pedal signal that automobile is in braking or during deceleration regime, signal is sent to battery management unit (BMS), enter the regenerative brake pattern, battery management unit is controlled DC-to-DC converter according to voltage, the current value of battery pack and capacitor bank, promptly operate to carry out buck or boost, the motor that is operated in generator mode is charged to battery pack, capacitor bank through inverter by PWM (pulse width modulation) ripple control DC-to-DC converter (DC-DC).
During the regenerative brake pattern, battery pack allows charging, and when capacitor bank also allowed to charge, greater than accumulator battery voltage, DC-DC carried out the boost operation as if capacitor bank voltage, not so carries out the buck operation.Battery pack allows charging, and capacitor bank does not allow charging, and DC-DC does not operate.Battery pack does not allow charging, and capacitor bank allows charging, and greater than accumulator battery voltage, DC-DC carries out the boost operation as if capacitor bank voltage, not so carries out the buck operation.Battery pack does not allow charging, and capacitor bank does not allow charging yet, and switch disconnects, DC-DC does not operate.
2, cold start-up, assistant starting pattern
Entire car controller is judged automobile according to vehicle speed signal, throttle signal and brake pedal signal and is in static, acceleration, climbing state, signal is sent to battery management unit, enter cold start-up, assistant starting pattern, battery management unit is controlled DC-to-DC converter according to voltage, the current value of battery pack and capacitor bank, promptly operate to carry out buck or boost by PWM ripple control DC-DC, make battery pack, capacitor bank provide power through inverter for the motor that is operated in electric motor mode, thereby further drive driving engine.
