Some main operating conditions are listed below to further describe the technical solution of the above embodiment of the present invention in more detail.
Preparing working conditions:
when a war alarm is given, the civil air defense works to prepare for the emergency. At the moment, the electric automobile rapidly returns to the parking space, and the charging and receiving pile is connected with an electric automobile power battery arranged in the electric automobile through a charging and receiving socket. And the people for the operation and maintenance of the civil air defense facility are fully charged with the uninterrupted power supply. The uninterruptible power supply includes one or both of a UPS and an EPS.
The operation working condition 1: distributed electric automobile power storage array circulation power supply
Part municipal power supply is destroyed or is influenced unable power supply under this operating mode, leads to municipal power supply to be in intermittent type power supply state. And in the interval when the municipal power supply stops supplying power, the distributed electric automobile power storage array and the double-power switching device are used for supplying power to the civil air defense power supply line and the civil air defense equipment. When the municipal power is restored, the power batteries of the electric vehicles in the distributed electric vehicle power storage array are fully charged for the next use.
