Abstract
A kind of power battery pack with high power characteristic and high capacity characteristics is to be linked together by several power type battery positive poles and several capacity type anodes using wire or conducting strip, equally, power type battery negative pole and capacity type GND are linked together using wire or conducting strip.Because power type battery internal resistance is smaller, the capacity type internal resistance of cell is very big, and when battery pack is under high-multiplying power discharge operating mode, power type battery internal resistance is small, can provide most of electric current, and the capacity type internal resistance of cell is big, is provided solely for limited electric current；When battery pack is under continuous discharge operating mode, together with power type battery and capacity type cell parallel, the voltage of power type battery is pind down by the voltage of capacity type battery, and capacity type battery can provide most of electric current, and power type battery provides limited electric current.The present invention can significantly improve the service life of battery, be adapted to use under various working environment.
Description
Technical field
The present invention relates to a kind of power battery pack with high power characteristic and high capacity characteristics.
Background technology
In recent years, electrokinetic cell is widely applied in each field, and electric automobile, track traffic, scene etc. all be unable to do without the battery of Large Copacity.Generally, the battery of Large Copacity is composed in parallel by the cell of several same performances, and power type battery group can carry out high magnification heavy-current discharge, but limited battery capacity；The battery capacity of capacity type battery pack is higher than power type battery, but can not carry out high magnification heavy-current discharge, otherwise has a strong impact on battery life.At present, battery industry is also without the battery pack of compatible power type battery and capacity type battery performance.
The content of the invention
The invention aims to provide a kind of power battery pack with high power characteristic and high capacity characteristics, it can carry out high magnification heavy-current discharge, while have the advantages of capacity type battery capacity is high, and continuous discharging time is long.
A kind of power battery pack with high power characteristic and high capacity characteristics of the present invention, it is that several power type battery positive poles and several capacity type anodes are linked together using wire or conducting strip, equally, power type battery negative pole and capacity type GND are linked together using wire or conducting strip, and forming one has the battery pack of cell parallel of a kind of power type battery and capacity type battery.
Because power type battery internal resistance is smaller, the capacity type internal resistance of cell is very big, and when battery pack is under high-multiplying power discharge operating mode, power type battery internal resistance is small, can provide most of electric current, and the capacity type internal resistance of cell is big, is provided solely for limited electric current；When battery pack is under continuous discharge operating mode, together with power type battery and capacity type cell parallel, the voltage of power type battery is pind down by the voltage of capacity type battery, and capacity type battery can provide most of electric current, and power type battery provides limited electric current.
A kind of power battery pack with high power characteristic and high capacity characteristics of the present invention, can use power type battery and capacity type battery equal proportion in parallel, and it is in parallel can also to carry out poor ratio according to battery pack applying working condition.
A kind of power battery pack with high power characteristic and high capacity characteristics of the present invention, can use super capacitor to replace power type battery and capacity type cell parallel composition power battery pack, improve battery pack quick charge and repid discharge performance.
A kind of power battery pack with high power characteristic and high capacity characteristics of the present invention, carried out using the general power type battery in market and capacity type battery in parallel, the battery pack of composition, which possesses power type battery group, can carry out high magnification heavy-current discharge, have capacity type battery capacity high simultaneously, the advantages of continuous discharging time is long, the service life of battery can be significantly improved simultaneously, adapt to use under various working environment.
