Study on the influence of the thermal protection material on the heat dissipation of the battery pack for energy storage

The thermal runaway chain reaction of batteries is an important cause the battery energy storage system (BESS) accidents, and safety protection technology key to protect BESS. Although flame retardant material can delay between reduce heat conduction batteries, it has a negative influence on normal dissipation batteries. In this paper, 12 series were assembled into pack. pack with closely arranged 3mm air gap studied. temperatures temperature differences these three types packs cyclically charged discharged at rated power, effects materials under charge/discharge cycle analysed.
