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