Description
Technical field
The present invention relates to battery subsidiary products technical field, be specifically related to the power supply device of the lead-acid battery on a kind of automobile.
Background technology
Development along with living standard; Automobile has become the topmost vehicles of people, and at present, the storage battery that uses on the automobile is mainly lead-acid battery; Lead-acid battery is a kind of device that chemical energy is transformed into electric energy; Belong to DC power supply, when its effect is ato unit, provide powerful starting current (generally up to 200～600A) to starter; When generator transships, can assist generator to supply power to power consumption equipment; When engine is in idling, supply power to power consumption equipment; When generator voltage is higher than the voltage of lead-acid battery, change a part of electric energy into chemical energy and store, just charge to lead-acid battery.Yet at present automobile adopts lead-acid battery mainly to have following shortcoming as storage battery, first, charging rate is slower, consume more fuel oil, discharges more tail gas; The second, energy storage efficiency is lower, and power is powerful inadequately; Three, useful life shorter, both made troubles to use, increase use cost again.
Summary of the invention
The technical problem that the present invention will solve provide a kind of can be to the quick charge of automobile lead-acid battery, the lead-acid battery life-span is provided and strengthens the battery power provisioning component of battery power performance.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of battery power feeding mechanism is characterized in that: comprise control section, lithium battery part and electrochemical capacitance part, the lithium battery part is with the parallel connection of electrochemical capacitance part and all be connected with control section; Control section comprises master control borad and MOS plate, and master control borad is electrically connected the MOS plate; Lithium battery partly is the lithium battery group, and it comprises some lithium batteries, and the lithium battery group is connected with master control borad; Electrochemical capacitance partly is an electrochemical capacitance, and electrochemical capacitance and lithium battery group are connected in parallel, its anodal positive pole that connects the lithium battery group, and negative pole connects the negative pole of lithium battery group through the MOS plate; The cathode output end P+ of just very this battery power feeding mechanism of lithium battery group, the negative pole of electrochemical capacitance are the cathode output end P-of this battery power feeding mechanism.If connect the automobile lead-acid battery with this power supply device, then its cathode output end P+ connects the positive pole of lead-acid battery, and cathode output end P-connects the negative pole of lead-acid battery.
Further, the connecting line between lithium battery group and the electrochemical capacitance is the thick line thicker than the connecting line between lithium battery group and the master control borad.
The MOS plate is a kind of protectiveness switch; It is opened and closes by master control borad control, and when the temperature of lead-acid battery was elevated to uniform temperature, master control borad opened the MOS plate through the voltage and current of control lead-acid battery; Thereby cut off the voltage and current of lead-acid battery; After the voltage of lead-acid battery was reduced to certain value, the master control borad master control borad made the MOS plate closing through the voltage and current of control lead-acid battery, and lithium battery will charge to lead-acid battery; The main effect of master control borad is: realize the temperature of control lead-acid battery, the balanced action of voltage and current between control lead-acid battery and the lithium battery.
The topmost application of dilute metal electrochemical capacitance is to be used for the stable DC bus voltage.Electrochemical capacitance has obtained extensive use at automotive field, is used to protect various engine control assemblys and microcontroller to avoid the interference that the momentary load sudden change causes voltage drop.The characteristic system of battery provides electric energy with long-time constant chemical reaction, and the charging interval is longer relatively.On the contrary, the charging of electric capacity is to accomplish through the voltage that is carried in its two ends, and charging rate depends on non-essential resistance more.Battery can be with substantially invariable voltage output electric energy in longer a period of time; And capacitance discharges speed is fast; Output voltage is the index law decay; Electrochemical capacitance has fast Absorption and the ability that releases energy, and is more suitable in realization regenerative braking mechanism than battery, so has constituted complementary relationship between battery and the electrochemical capacitance.
Because but lead-acid battery is safe, cryogenic discharging characteristic is preferable, characteristics such as tool overdischarge and high efficiency discharge, not only make lead-acid battery no longer lonely; More can become three-in-one battery with lithium Fe battery, electrochemical capacitance; On cost price, functional efficiency, more can complementation concoct to optimum state; And need not revise original system, thereby be the most economical effective and efficient manner of recent battery development design.
The present invention can adopt the present invention can reach following good effect as the power supply device of automobile lead-acid battery: the first, quick charge, high-power output can promote vehicle reaction and driving usefulness; The second, gasoline is fully burnt, can reduce oil consumption, economize and use oily 10-15%, reduce toxic emission, reduce CO emission 25-30%; Three, can make the throttle reaction become good, strengthen engine running efficient, promote horsepower 10-20%; Four, storage battery high power heavy-current discharge is provided, prolongs lead-acid battery life-span 1-2 doubly; Five, volume is reasonable, and installing/dismounting is applicable to all kinds vehicle.Also more energy-conserving and environment-protective simultaneously meet the trend that low-carbon (LC) is lived.
