Abstract
The utility model discloses a battery power supply, which comprises a casing as well as a battery pack and a battery protective circuit board arranged in the casing, a heating element is disposed on the circuit board, and a phase-change material is arranged between the heating element and the internal wall of the casing. Because the phase-change material is arranged between the heating element and the casing on the circuit board, heat produced by the heating element can be absorbed by the phase-change material, and can be transferred to the outside of the battery pack through the battery pack casing, thereby ensuring the heat dissipation effect of a discharge protecting board, and being favorable for enhancing the reliability of the battery power supply.
