The invention discloses a fast power transformation 
station of a battery box of an electric automobile and a 
replacement method of the battery box. The power transformation 
station at least comprises the following devices: an automobile positioning platform, a battery box lifting and replacing platform, a stacking 
machine, a battery box storage rack, a logistics transmission port of the battery box and a delivery roller way which are symmetrically arranged relative to the longitudinal movement axis of the stacking 
machine, the simultaneous working of the two power 
transformation systems can be achieved, and the space 
utilization rate and the power 
transformation efficiency are improved. The fast power transformation 
station also comprises a power supply 
system which is arranged on a roof and consists of a solar 
photovoltaic power generation battery board; and self sufficiency of power can be achieved by virtue of the 
solar energy, the power supply of the equipment in the station or the charging for the battery box in the station are met. The invention also provides the 
replacement method of the battery box of the power transformation station. According to the power transformation station, the distribution is reasonable, the space 
utilization rate is high, the work of the equipment is reliable and simple, and the power transformation process is fast, so that the power transformation time can be shortened, the power transformation fault is reduced, and the compatibility for different vehicles and different battery boxes is also improved.
