Efficient parking lot battery automatic replacing and parking system of electric vehicle

Abstract

The invention particularly relates to an efficient parking lot battery automatic replacing and parking system of an electric vehicle. The system is high in intelligent degree, saves space and is convenient to use. A central processing unit of the system sends an entrance signal to the vehicle and sends a stay time enquiry signal, the vehicle feeds back stay time T1, the stay time T1 is compared with a standard stay time T2 stored in a storage module, if T1 is larger than or equal to T2, after a walking robot drives in place, an electric push rod of the walking robot below a vehicle chassis draws back, and a driving wheel of the walking robot rotates and dries a supporting shell to draw back; the central processing unit sends a current movement route of the walking robot to an auxiliary processor, and the walking robot automatically returns to a robot installation device; the driving wheel capable of drawing back and stretching out arranged on the walking robot drives the supporting shell, and the walking robot adapts to the narrow environment of the parking lot; linear walking or left-right transverse moving can be realized through universal wheels on the walking robot, and the space utilization rate of the parking lot is increased.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an efficient battery automatic replacement and parking system for parking lots of electric vehicles. Background technique [0002] Electric vehicles drive vehicles through the electric energy stored in batteries, which reduces the use of fossil energy by vehicles and is an important means to solve national energy problems. Due to the limitation of the current battery energy density, at the current level of battery technology development, battery charging usually takes several hours to complete, and the battery charging cannot be completed in a short time, and the battery charging with a large current will have a negative impact on the battery life. In addition, the current parking lot is mainly stored flat, occupying a large area of ​​land, so the number of storage is limited, it is difficult for car owners to find a parking space, and there is no protection for the car...

Problems solved by technology

[0004] Patents related to lifting replacement methods, such as the battery replacement robot described in CN201280003179, include a battery plugging mechanism, a lifting mechanism, etc., and the lifting mechanism makes the battery plugging mechanism go up and down, but the problem that it cannot solve is: for the existing In the parking lot, the renovation cost is high, and a set of replacement system can only satisfy one car at the same time, and it is impossible to quickly change batteries and charge multiple cars in the parking lot; patents related to the side pull-out replacement method, such as CN201510809560 What is described is a side battery replacement device for electric vehicles, including a battery box installation unit, a lifting unit, a control unit, and a locking unit; There is no judgment on the amount of electricity, resulting in low intelligence and many manual operations; the existing patents related to the automatic parking system of the parking lot, such as the automatic parking system described in CN 201510021169, include: parking spaces, mobile charging Robot and robot management system, the charging robot includes the robot body, fire fighting unit, traveling mechanism, battery pack and control unit, etc.; this system can facilitate the charging of electric vehicles at any time during the parking lot , the charging robot cannot meet its long-term charging needs, and if it needs to be charged for a long time, the charging robot is too large to be used in a narrow environment such as a parking lot; and in some cases, when the battery is damaged and must be replaced, it cannot To achieve replacement, it is also impossible to adapt to the special situation where the battery is replaced from the side
