Description
Technical field
The present invention relates to battery product technical field, be specifically related to a kind of energy-storage battery.
Background technology
Energy-storage battery mainly instigates the storage battery for field savings energy such as solar power plant, wind power plant, regenerative resource, the vehicles, stand-by power supplies, and common energy-storage battery is lead-acid battery, and it has boundless range of application.The advantage of lead-acid battery is cheap, and production technology is simple, requires very low; But its shortcoming is also clearly, as short in cycle life, self discharge is large, specific energy is little, weight is large, and plumbous and sulfuric acid all contaminated environment.Therefore, simple lead-acid battery is adopted to be apparent as the shortcoming of energy-storage battery.And on the other hand, lithium battery have have extended cycle life, discharge platform is mild, voltage that is single battery is high, the high namely battery of energy density is relatively lighter, is not suitable for independent application equally at present.Moreover the super capacitor (electrochemical capacitance) that development in recent years is got up has charging interval short, the feature such as long service life, good temp characteristic, energy savings and environmental protection.But electrochemical capacitance is not equal to battery, in some application, it may be better than battery, if therefore can be combined with each other application, the high energy storage feature of the power characteristic of electrochemical capacitance and battery is combined, should reach more excellent effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide the three-in-one hybrid energy-storing battery that a kind of power is high, battery durable ability is strong, the charging interval is short, the life-span is long.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of three-in-one hybrid energy-storing battery, it is characterized in that: comprise control section, lithium battery part, lead-acid battery part and electrochemical capacitance part, lithium battery part is with electrochemical capacitance part in parallel and be all connected with control section, and lead-acid battery part is connected with lithium battery part and electrochemical capacitance part; Control section comprises master control borad and MOS plate, master control borad electrical connection MOS plate; Lithium battery part is lithium battery group, and it comprises some lithium batteries, and lithium battery group is connected with master control borad; Electrochemical capacitance part is an electrochemical capacitance (i.e. super capacitor), and electrochemical capacitance and lithium battery group are connected in parallel, and its positive pole connects the positive pole of lithium battery group, and negative pole connects the negative pole of lithium battery group by MOS plate; Lead-acid battery part is a lead-acid battery, and the positive pole of lead-acid battery connects the positive pole of lithium battery group, and the negative pole of lead-acid battery connects the negative pole of electrochemical capacitance.This place's three-in-one hybrid is finger and integrates lithium battery group, lead-acid battery and electrochemical capacitance.
Further, lithium battery group and electrochemical capacitance, lithium battery group and lead-acid battery and the connecting line between lead-acid battery and electrochemical capacitance are the thick line thicker than the connecting line between lithium battery group and master control borad.
MOS plate is a kind of protectiveness switch, control it by master control borad to open and close, when the temperature of lead-acid battery is elevated to uniform temperature, master control borad makes MOS plate open by the voltage and current controlling lead-acid battery, thus cut off the voltage and current of lead-acid battery, after the voltage of lead-acid battery is reduced to certain value, master control borad makes MOS plate closing by the voltage and current controlling lead-acid battery, lithium battery will charge to lead-acid battery, the Main Function of master control borad is: realize the temperature controlling lead-acid battery, control the balanced action of voltage and current between lead-acid battery and lithium battery.
The topmost application of dilute metal electrochemical capacitance is used to stable DC bus voltage.Electrochemical capacitance is widely applied at automotive field, causes the interference of voltage drop for the protection of various engine control assembly and microcontroller from momentary load sudden change.The characteristic system of battery provides electric energy with chemical reaction constant for a long time, and the charging interval is relatively long.On the contrary, the charging of electric capacity is that the voltage by being carried in its two ends has come, and charging rate depends on non-essential resistance more.Battery can export electric energy with substantially invariable voltage within longer a period of time, and the velocity of discharge of electric capacity is fast, output voltage exponentially rule decay, electrochemical capacitance has the ability absorbing fast and release energy, be more suitable for realizing regenerative braking regime than battery, therefore constitute complementary relationship between battery and electrochemical capacitance.
Because lead-acid battery fail safe high and low temperature flash-over characteristic is better, tool can the characteristic such as 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, cost price, functional efficiency more can complementaryly be concocted to optimum state, and do not need to revise original system, because of but the recent most economical effective mode of battery development design.
The present invention is by being integrated in one lithium battery, lead-acid battery and electrochemical capacitance, and adopt unified control section to control, so by lithium battery have extended cycle life and energy density is high, the low-cost and easy-to of lead-acid battery is produced, the quick charge life-span of electrochemical capacitance is long etc. that characteristic combines, reach the effect of learning from other's strong points to offset one's weaknesses, its application widely, can be used for the fields such as the energy-storage battery of the vehicles (automobile), stand-by power supply, solar energy or wind power generation; Lithium battery and electrochemical capacitance can play a protective role to lead-acid battery, make lead-acid battery discharge and recharge as required, avoid its temperature too high, can extend the life-span of lead-acid battery, have moment charging and discharging capabilities, can meet quick power supply equipment demand completely; Also more energy-conserving and environment-protective simultaneously, meet the trend of low-carbon (LC) life, therefore have very large economic and social benefit.
