Get PriceWhen a coulomb drops through a volt, it loses potential energy 1 joule. This energy is dissipated as heat. When a current of (I) coulombs per second falls through a potential difference of (V) volts, the rate of dissipation of energy is (IV), which can also be written (by making use of Ohm''s law) (I^2R text{ or }V^2/R).

Get PriceA common approach to thermal storage is to use what is known as a phase change material (PCM), where input heat melts the material and its phase change — from solid to liquid — stores energy. When the PCM is cooled back down below its melting point, it turns back into a solid, at which point the stored energy is released as heat.

Get PriceThe heat generated on charge is finite, i.e. once the battery is fully charged no more heat is generated but at this point the battery enters the float charge phase and as long as the battery is on charge, heat is being generated. Heat generated on discharge is also finite because once the battery is fully discharged no more heat will be generated.
Get PriceHeat 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.
