Description
Technical field
The utility model belongs to battery technology field, and in particular to a kind of lithium battery group.
Background technique
Lithium-ion-power cell has become the main energy storage component of new-energy automobile.For convenience of layout, safety is improved, is increased
Big versatility and quickening research and development process, automobile-used lithium-ion battery systems are substantially all using modularized design lithium-ion electric core itself
Temperature rise very big threat is caused to the safety of battery, also have a great impact to the performance of battery.Moreover, different batteries
Module design, battery module it is thermally conductive also different from heat-sinking capability.Capacity of heat transmission difference will lead to the temperature one of battery module
Cause property is deteriorated, and non-uniform temperature will lead to coupled thermomechanics between battery cell, accelerates the aging of battery pack.And heat-sinking capability difference can be led
The temperature rise of module entirety is caused to get higher, high temperature meeting accelerated corrosion battery shortens the service life of battery.
