Non-independent thermal design lithium battery temperature control method

The invention relates to a non-independent thermal design lithium battery temperature control method in the technical field of thermal control. The method comprises the following steps: S1, selectinga lithium battery heat dissipation surface region which is a nearby region with a relatively stable external heat flow environment; S2, acquiring hemispherical emissivity required by the surfaces of alithium battery and a mounting plate, wherein the hemispherical emissivity is acquired through simulation analysis; S3, adjusting comprehensive hemispherical emissivity, wherein the comprehensive hemispherical emissivity is adjusted by adhering a metallized plastic film thermal control belt to the outer surface of the lithium battery and/or the surface of the lithium battery mounting plate; S4, homogenizing the temperature of each monomer of the lithium battery through a pre-buried heat pipe in the lithium battery mounting plate; and S5, pasting heating sheets on the surfaces of the lithium battery monomers and the pr
