The following describes a battery replacement process of a vehicle to be replaced by the battery replacement station in combination with the above battery replacement station structure. When the vehicle to be switched triggers the low-electricity threshold, the vehicle dispatching system communicates with the control system of the battery changing station to determine whether the current battery changing station has an idle switching potential and a battery unit 9 meeting the electricity requirement.

And when the confirmation reply of the control system is obtained and the current power change station meets the power change requirement, the vehicle scheduling system carries out route planning and controls the vehicle to be changed to run to the current idle potential change (namely, the specified potential change). The wheel of the electric vehicle to be replaced enters between the first positioning block 51 and the second positioning block 52 to be positioned. After the vehicle to be changed reaches the designated potential changing point, the vehicle to be changed identifies the two-dimensional code through the code reader and sends an identifying and reading message to the control system, so that the control system judges that the vehicle to be changed is in place. And, the self-checking of the vehicle to be changed is fed back to the vehicle dispatching system after being communicated with the brush block 41. The vehicle dispatching system is communicated with a control system of the battery replacement station to inform that the battery replacement preparation work of the vehicle to be replaced is completed, and the battery replacement action can be executed. The brush plate in the vehicle to be switched is fully contacted with the brush block 41 arranged on the ground, a certain pre-pressure is formed between the brush plate and the brush block 41, and the current supplies power to the electric equipment in the vehicle to be switched through the brush block 41 and the brush plate, so that the vehicle to be switched is continuously in an awakening state in the process of disassembling and assembling the battery unit 9, the repeated starting time of the vehicle to be switched is shortened, and the battery switching efficiency of the whole battery switching station is improved.
