There are temperature differences for the object of battery 6 and external contact, heat are transmitted to cryogenic object macroscopically, being high temp objects, microcosmic
On, unordered warm-up movement is carried out for the microcosmic particle in substance.Thermal convection, thermal convection happen in fluid and another fluid or
Between person's solid, the heat that surrounding is taken away while relative motion occurs for fluid.Heat transfer is also occurred that while thermal convection,
Thermal convection single cannot exist, and own temperature increases when 6 charge and discharge of lithium battery, and the raised lithium battery 6 of temperature is contacted with surrounding
