Heat dissipation design for lithium-ion batteries
Chen and Evans [8] investigated heat-transfer phenomena in lithium-polymer batteries for electric vehicles and found that air cooling was insufficient for heat dissipation from large-scale batteries due to the lower thermal conductivity of polymer as well as the larger relaxation time for heat conduction. Choi and Yao [2] pointed out that …
power dissipation
Heat is generated from other than effective power. Effective power is used to drive the load. Thus, "4.2V * 3A * 30/60h" is a straight calculation of (though need some more considerations) power we are drawing from the battery, but not the power to generate heat. Heat is generated from "inefficiency", offset to an ideal power source.
