Service life and performance have an impact, and battery PACK systems have stringent seal request, such as IP67.There is heat in battery charge and discharge process
Amount generates, these heats need to shed outward in time under conditions of environment temperature is excessively high, prevents temperature in chest from increasing；When
When environment temperature is relatively low, and these heats is wished to stay in chest.
General way in industry：It is cooled down using liquid circulation when high temperature, as shown in Fig. 2, using cold equipped with coolant liquid 4
But pipe 5, are wound on the surrounding of battery core 3, and when low temperature keeps the temperature battery system using heating film mode of heating and thermal insulation material；It is this to do
Method battery system structure is complicated, with high costs, needs cooling and keeps the temperature two sets of facilities.
Invention content
The technical problem to be solved in the present invention is to provide a kind of novel heat-conducting material in dynamic lithium battery module and pack
On application, only need a set of facility to be just able to maintain that the shell body temperature of dynamic lithium battery module or pack systems in best temperature
It spends in range, to improve the discharge capacity of battery, promotes the comprehensive performance of dynamic lithium battery module or pack systems.
The present invention is realized by following proposal：A kind of novel heat-conducting material answering on dynamic lithium battery module and pack
With, it is characterised in that：The novel heat-conducting material is as the material with two kinds of characteristics of heat-insulation and heat-preservation and heat conduction in dynamic lithium battery
Application on module and pack, the application be in dynamic lithium battery module or the shell of pack systems, when temperature compared with
Gao Shi has thermal conduction characteristic, when the temperature is low, and has heat-insulation and heat-preservation characteristic.
The application is when the shell body temperature of dynamic lithium battery module or pack systems is higher by battery system
In heat transfer to external environment in pack casees, shell body temperature is reduced；When dynamic lithium battery module or pack systems

Pond module or cell p ack systems are kept the temperature and are radiated, which has heat preservation and two kinds of characteristics of heat conduction：When
When temperature is higher, novel heat-conducting material has thermal conduction characteristic, when the temperature is low, and has heat-insulation and heat-preservation characteristic；And it is novel
Heat Conduction Material is with the rising of temperature, and the thermal coefficient rising of novel heat-conducting material, the capacity of heat transmission increases, at temperature
Drop, thermal coefficient decline, and the capacity of heat transmission reduces, and heat-insulating capability increases, and show heat preservation property；
2, in the shell of dynamic lithium battery module or when battery system pack the temperature inside the box is higher, due to novel heat-conducting material
Good heat conductivity, can more quickly by the shell of dynamic lithium battery module or in battery system pack casees heat pass
Be handed in external environment, reduce dynamic lithium battery module shell in or battery system pack the temperature inside the box；When power lithium
In the shell of battery modules or when battery system pack the temperature inside the box is relatively low, novel heat-conducting material thermal conductivity is also less than normal, every
Good in thermal property, can be by the shell of dynamic lithium battery module or battery system pack the temperature inside the box maintains, therefore, setting
Novel heat-conducting material can more easily maintain in the shell of dynamic lithium battery module or battery system pack the temperature inside the box exists
In optimum temperature range, to improve the discharge capacity of battery, the comprehensive of dynamic lithium battery module or cell p ack systems is promoted
Close performance；
3, structure of the invention is simple, at low cost, only need to be in the shell of dynamic lithium battery module or battery system pack casees
One layer of novel heat-conducting material of interior patch, you can maintain in the shell of dynamic lithium battery module or battery system pack the temperature inside the box exists
In optimum temperature range, without the cooling facility of in addition setting and lagging facility.
