A heat conducting aluminium sheet is arranged between each two single battery cells, and the single battery cells and the heat conducting aluminium sheet are sequentially jointed. A flexible heat conducting silicon rubber case is arranged on each single battery cell, so as to prevent the periphery of the single battery cell from collision during the use. The utility model has the advantages that the whole battery cell module has favorable heat dissipation performance, the whole battery pack has good structural strength and favorable vibration resistance, battery cell tabs are reasonably coupled in order, and short circuits can be efficiently avoided.
Description
Technical field
The utility model relates to a kind of battery pack, particularly a kind of electrostrictive polymer core group.
Background technology
At present, domestic electric motor car generally adopts single electric core capacity to carry out also, connect up to the iron lithium dynamical battery more than the 50-100Ah, thereby the mode that forms the electrokinetic cell bag is the vehicle power supply.Receive automobile in when operation road conditions and the influence of weather complexity, require power brick to want that ability is shockproof, heat dispersion is good, insulation property are good.Present power brick all can not satisfy these needs aspect the level of informatization of fail safe, reliability, durability and control system, and especially more common lead-acid battery, the Ni-MH battery in coefficient of safety aspect compared to lack effectively and ensured.
In sum, need at present to improve the level of informatization of fail safe, reliability, durability and the control system of power brick, provide that a kind of ability is shockproof, heat dispersion, the good electrokinetic cell bag of insulation property.
The utility model content
The utility model technical problem to be solved is the shortcoming that present employed battery pack exists, and designs a kind of electrostrictive polymer core group again.
The utility model is realized above-mentioned purpose through following technical scheme:
Have fail safe, reliability, the relatively poor shortcoming of durability to existing battery pack, design a kind of electrostrictive polymer core group again, comprise the monomer electricity core more than two or two, the quantity of monomer electricity core is decided according to the situation that product uses.Parallel with one another between the described monomer electricity core, be provided with a slice heat conduction aluminium flake between the monomer electricity core, monomer electricity core and heat conduction aluminium flake are fitted successively.Every monomer electricity core is provided with soft thermal conductive silicon gum cover, prevents to be collided around the monomer electricity core in the use.
Described soft thermal conductive silicon gum cover is made up of the soft heat conductive silica gel egative film of a slice and a soft heat conductive silica gel frame.Soft heat conductive silica gel egative film and soft heat conductive silica gel frame fit, and described monomer electricity core is placed in the soft heat conductive silica gel frame.
One lateral edges of described heat conduction aluminium flake is provided with wave shaped radiator, the heat that produces when helping to reduce the work of monomer electricity core.
As the further improvement of the utility model, the lug of the same polarity of described monomer electricity core is followed closely connection admittedly through compressing tablet, spring washer and polarity screw on lug lower sheeting, the lug; Described lug is placed on lug lower sheeting and the lug between the compressing tablet, and compressing tablet is followed closely fixed connection admittedly through spring washer and polarity screw on lug lower sheeting and the lug.Connect the lug of all monomers electricity cores through compressing tablet on lug lower sheeting, the lug, spring washer and polarity screw, technical disadvantages such as the rosin joint that can effectively avoid existing through welding manner in the technology in the past, loose contact.
Owing to raise because of loose contact causes the local electrical resistance of lug easily at the lug place during battery pack work, can produce a large amount of heats after the long-time running.So the place is provided with temperature detection sensor at described lug, control appliance can be understood the real-time working temperature of this device through temperature detection sensor.
Each monomer electricity core is placed in the plastic cement drain pan, and the end face of described plastic cement drain pan and bottom surface all offer louvre.Connect through bolt between the end face of described plastic cement drain pan and the bottom surface.The plastic cement drain pan has the good insulation performance, avoids electrified body (for example lead, data wire etc.) to contact with metal material, can effectively avoid short circuit, improves the coefficient of safety of power brick.
As required, the described monomer electricity of the utility model core quantity is six.
The utlity model has following advantage:
1. whole electric core group heat dispersion is good: because between the monomer electricity core fin is arranged, can effectively reduce entire cell module temperature;
2. entire cell pack arrangement intensity is good, and anti-seismic performance is good: all monomers electricity cores all are fixed in the plastic cement drain pan, and whole electric core group pack arrangement intensity, anti-seismic performance are good, can satisfy complex work environment such as automobile, electric motor car;
3. the inner cabling of power brick can effectively be avoided short circuit rationally, in order: monomer electricity core avoids electrified body (for example lead, data wire etc.) to contact with metal material through plastic cement drain pan parcel, can effectively avoid short circuit, improves the coefficient of safety of power brick.
