Technical staff technology require higher, it is necessary to be familiar with production assembly technology and the electrical principle of battery bag,
It is unfavorable for the popularization of product.
Utility model content
This utility model is for solving above-mentioned technical problem, it is provided that a kind of electrokinetic cell bag, it is intended to solve to work as battery
The internal cell of bag occurs when pressure reduction is bigger, and battery bag to be equalized by external power source, needs dismounting electricity
Chi Bao, or when battery bag goes wrong, need to dismantle battery bag, the battery in battery bag surface configuration
Bag equilibrium mouth, supply external power source connects use.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is:
A kind of electrokinetic cell bag, including two or more cell, two or more monomer voltage gather wire harness,
Battery management chip, low voltage communication mouth and high-voltage connector mouth, also include that battery bag equalizes mouth；Described monomer
Battery is connected in series, and described battery management chip gathers wire harness by monomer voltage and connects cell the two poles of the earth；
Described low voltage communication mouth connects battery management chip；Described battery bag equilibrium mouth is arranged on electrokinetic cell bag surface,
Described battery bag equilibrium mouth includes two or more passage, and described passage is by connecting described monomer voltage gathering line
Bundle connects cell the two poles of the earth.
Provide the benefit that: battery bag surface configuration has battery bag to equalize mouth, and external power supply connects this battery Bao Jun
Heng Kou just directly can carry out charge and discharge equilibrium to the cell in battery bag, it is not necessary to dismounting battery bag, convenient
Safeguard, be greatly shortened maintenance period, reduce the popularization of maintenance cost, beneficially product, and can be pointedly
The cell selected to any one is charged, and is conducive to extending the cell life-span.
This utility model optimizes further, in order in time battery status be fed back to outside, it is simple to battery and
Shi Jinhang charge and discharge equalizes.Described low voltage communication mouth is connected with battery management chip by CAN.Cell tube
Battery status information is fed back to low voltage communication mouth by CAN by reason system in time, and external equipment can pass through
Connect low voltage communication mouth, get battery status information, in time battery is carried out the charge and discharge equilibrium of necessity.
This utility model optimizes further, in order to any one cell independently carries out charge and discharge balancing.
Described battery bag equilibrium mouth is cylindrical connector, and shape is similar to aviation round electric connector, described battery bag
More than four pin holes, corresponding two pin holes of passage it are provided with in equilibrium mouth.Control different pin holes is entered
Row charge and discharge equalizes, thus the cell that different passages are corresponding is carried out independent charge and discharge equilibrium.
This utility model optimizes further, during in order to make external plug-in component insert battery bag equilibrium mouth, will not loosen.
The snap ring of an outwardly convex it is provided with inside described battery bag equilibrium mouth.External plug-in component is provided with the groove of correspondence,
It coincide with projection when inserting battery bag equilibrium mouth, prevent from loosening.
This utility model optimizes further, in order to improve the heat-resisting ability of battery bag equilibrium mouth.Described battery
The material of bag equilibrium mouth is politef or silica gel.The use of exotic material so that it is in charging process
In or the higher environment of temperature in increase the service life.
The novel further optimization of this use, in order to disposably charge to all cells.Described high pressure patches
Part mouth is connected to the two poles of the earth of described electrokinetic cell bag.External power supply is directly connected to high-voltage connector mouth, can be right
All of cell charges.
