The invention relates to the field of batteries and electric automobiles, in particular to a battery pack, a walking type battery trolley and a combined type electric automobile. The battery pack comprises a main battery, a fireproof emergency battery, a shell and an electric connector module, wherein the main battery and the fireproof emergency battery are arranged in the shell; the fireproof emergency battery is isolated from the main battery through a protective layer made of an anti-deflagration material, and can provide emergency power for a cooling device, a fire extinguishing device and the like when the main battery is in thermal runaway. The walking type battery trolley provided with the battery pack can drive the walking type battery trolley to leave a dangerous area when the main battery is in thermal runaway. The combined type electric vehicle battery compartment is provided with the battery pack or the walking type battery trolley, and when thermal runaway spontaneous combustion of a main battery occurs, the battery pack or the walking type battery trolley can be automatically separated from the battery compartment and descend to the ground, or the walking type battery trolley travels to leave a safe distance, so that a vehicle body is prevented from being burnt.

    本发明涉及电池及电动汽车领域,特别是一种电池组、行走式电池小车及组合式电动汽车。所述电池组,包括主电池、防火应急电池、壳体、电接头模块:主电池和防火应急电池安置在壳体内;防火应急电池通过抗爆燃材料构建的保护层与主电池隔离,能在主电池热失控时向冷却装置、灭火装置等应急供电。装有上述电池组的行走式电池小车,能在主电池热失控时驱动行走式电池小车离开危险区。组合式电动汽车电池仓配装所述电池组或所述行走式电池小车,当发生主电池热失控自燃时,电池组或行走式电池小车能自行与电池仓分离并降至地面,或行走式电池小车再行驶离开至安全距离,避免造成汽车车体烧毁。
