The invention discloses a battery engine rapid cold start system, an automobile and a cold start method, a fuel cell stack, a radiator and a first cooling liquid pump form a cooling liquid large circulation loop through pipelines, and the battery engine rapid cold start system further comprises a thermostat which is arranged on the pipeline between the radiator and the first cooling liquid pump. The thermostat is communicated with a pipeline between the fuel cell stack and the radiator through a pipeline, the thermostat, the fuel cell stack and the first cooling liquid pump form a cooling liquid small circulation loop, a vacuum heat preservation tank is arranged on the pipeline between the thermostat and the first cooling liquid pump, and a liquid inlet pipe and a liquid outlet pipe are respectively arranged on the vacuum heat preservation tank. The end parts, exposed out of the vacuum heat preservation tank, of the liquid inlet pipe and the liquid outlet pipe are respectively communicated with a pipeline between the thermostat and the first cooling liquid pump; a second cooling liquid pump is arranged at the exposed part of the liquid inlet pipe; the cooling liquid with residual heat in the vacuum heat preservation tank is pumped into the fuel cell stack, and rapid cold start of the fuel cell is facilitated.

    本发明公开了一种电池发动机快速冷启动系统、汽车及冷启动方法,燃料电池电堆、散热器以及第一冷却液泵两两之间通过管路构成冷却液大循环回路,还包括节温器,节温器设置于散热器和第一冷却液泵之间的管路上,且节温器通过管路连通于燃料电池电堆和散热器之间的管路上,节温器、燃料电池电堆以及第一冷却液泵构成冷却液小循环回路,所述节温器和第一冷却液泵之间的管路上设有真空保温罐,该真空保温罐上分别设有进液管和排液管,进液管和排液管露设于真空保温罐外的端部分别连通于节温器和第一冷却液泵之间的管路上,所述进液管外露部分设置有第二冷却液泵;本发明将真空保温罐内余温的冷却液泵入燃料电池电堆内,有利于燃料电池快速冷启。
