Problem, and electrokinetic cell operating current is big, quantity of heat production is big, it is necessary to quickly the heat transfer of electrokinetic cell is distributed, and prevents
The too high generation potential safety hazard of temperature；Under cryogenic, the startability of vehicle can be deteriorated lithium-ion-power cell, thus pure electricity
Electrical automobile power battery pack needs to be incubated or heat measure.Current high temperature radiating and low-temperature startup performance are electric car power supply systems
One of subject matter that system presently, there are.
Traditional Soft Roll power battery module design is punched first at cell polar ear, is gone here and there or several several with high temperature gummed tape
And battery core is intertwined, then with support on inserts conflux piece fastened by screw assembling, two sides paste EVA foams,
With heat-shrinkable T bush entirety pyrocondensation；This technique punched at cell polar ear heavy damage cell polar ear overcurrent capability and increase lug
Internal resistance, cause battery core to descend temperature to raise in working order, fasten lug and conflux piece in internal stent by screw, this operation
Difficult and fragile cell polar ear；It is outside that the radiating for having a strong impact on battery core is coated using heat-shrinkable T bush；Said structure technique is serious
Security of the influence lithium-ion-power cell in new-energy automobile application.
To solve the above problems, two technologies of aspect of radiating and heating are considered simultaneously in the prior art, also there are some Shens
Patent and please differ from one another, such as：CN201210215864.6《Temperature controllable type lithium ion battery module for vehicles》, battery is by dustpan
Type aluminium box is transferred heat on the aluminum heat conducting plate of both sides, and heat is drawn out to semiconductor chilling plate radiating from above aluminum heat conducting plate
Cooling water is connected with plate, inside heat sink to take away heat.There is one piece of thermal insulation board between heat sink and aluminum heat conducting plate, thermal insulation board will
Inside battery is kept apart with outside batteries, and one is provided with above thermal insulation board with an equal amount of mouth of cooling piece, and cooling piece is placed on it
The middle function of completing refrigeration (or heating).This process is to control electric-control system by the sense electronicses thermometer bulb in aluminum heat conducting plate
It is automatically obtained.
CN201310522402.3《For the device of the battery module of indirect cooling environment protection type automobile》, including：Heat conduction circle
Panel, wherein being embedded with the heat pipe of overmolded, the thermally-conductive interface plate is arranged between at least two element cells；And radiator,
The upper end of its heat pipe for being integrally connected to each overmolded, the radiator is arranged in cooling air stream.So as to improve boundary

Point.
And prior art is for the most of use of research of heat transfer medium or traditional single cooling air mode, and
Foreign countries have begun to such as research of liquid cooling mode, phase-change material to new heat transfer medium.
Cooling air mode is cheap but radiating effect is poor, liquid cooling mode efficiency high, is following electrokinetic cell heat
The important development direction of management system；Common liquid cooling mode is to spread to dissipate pipeline inside battery bag, can so compare and account for
With inner space, it is most important that liquid cooling uses the major safety risks that there is leakage inside battery bag.
Lug, is a kind of conductor of lithium ion polymer battery product.Battery is a point both positive and negative polarity, and lug is exactly from battery core
The middle metallic conductor for extracting both positive and negative polarity, the popular ear for saying battery positive and negative polarities is the contact when discharge and recharge is carried out
Point.Lug is divided into three kinds of materials, and the positive pole of battery uses aluminum, and negative pole uses the nickel material, negative pole also to have copper to plate nickel material, it
Be all to be composited by film and metal tape two parts.The attachment structure of existing lug there is also many deficiencies simultaneously.
Even so, prior art also needs to continue to optimize.
