Embodiment 1

[0035] Such as figure 1 As shown, a method for automatically replacing batteries in an electric vehicle comprises the following steps:

[0036](1) After the electric vehicle arrives at the parking area, the sensor in the parking area tests the pressure value of the parking area and outputs a voltage signal to the control system. When the pressure value in the parking area is greater than YkN, Y≥0, where Y is selected 1. The control system controls the start of the battery replacement device; the control system is a computer. When the pressure value is greater than 1kN, the computer receives the signal and then drives the switch of the pressure relay to close. , A component that makes electrical contacts act. The pressure relay can also be defined as a hydraulic component that converts pressure into an electrical signal. The customer can output an electrical signal at a certain set pressure by adjusting the pressure relay according to his own pressure design needs. The pressu...

Embodiment 2

[0047] Basically the same as embodiment 1, preferably, a protective layer is provided on the side of the strain gauge far away from the bottom plate, which effectively improves the stability of the strain gauge test, reduces the interference of the external environment and then reduces the error of the test; the protective layer is a PET film , PU film or elastic polymer composite material, the protective layer of this material has stable performance and long service life.

Embodiment 3

[0049] Basically the same as embodiment 1, preferably, the speed sensor installed inside the battery replacement device in step (2) is a spatial filter, the spatial filter has better control accuracy performance, and can effectively adjust the speed of the battery replacement device during walking. Its speed makes the speed control of the battery replacement device more accurate, effectively reduces the error, and makes the replacement of the electric vehicle battery more accurate and rapid; the spatial filter and the battery replacement device move synchronously to measure the time of the signal in the unit space Frequency; the working principle of the spatial filter is as follows: the spatial filter includes a grid plate, and there are N equidistant grid gaps in the space length L. When the moving speed of the grid plate is v, the time for moving the distance L is t 0 ;

[0050] Spatial frequency: (number of changes per unit space length)

[0051] time frequency:

Abstract

The invention discloses an automatic battery replacing method of an electric vehicle, and belongs to the technical field of battery replacement. The replacingproblems of low-efficiency and labor-consuming of theelectric vehicle in the prior art are aimed at. The automatic battery replacing method of the electric vehicle comprises the steps that after the electric vehicle arrives at a parking area,the pressure value of the parking area is tested by a sensor in the parking area, and when the pressure value is greater than YkN, a battery replacing device is activated; the battery replacing device slides along the track in the parking area, the speed sensor in the battery replacing device cooperates with a travel switch arranged on the slide rail to adjust the speed of the battery replacing device at any time, and the battery replacing device stops when adesignated position is reached;the battery replacing device stops at the designated position and then completes replacement of the electric vehicle battery, and when battery replacement is completed, the electric vehicle exits the parking area;and the entire process is automated, the manual participation level is reduced, the replacement efficiency of the electric vehicle is more efficient, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of battery replacement, and more specifically relates to a method for automatically replacing batteries of an electric vehicle. Background technique [0002] Electric vehicles drive vehicles through the electric energy stored in batteries, which reduces the vehicle's dependence on fossil energy and is an important means to solve national energy security issues. Due to the limitation of the current battery energy density, the driving range of electric vehicles is usually 100 to 200 kilometers, which is far from the driving range of traditional cars, which usually exceeds 500 kilometers. Therefore, whether electric vehicles can be quickly and conveniently supplemented with electric energy will become an important factor affecting the use and promotion of electric vehicles. At the current level of battery technology development, battery charging usually takes several hours to complete, and it is impossible to ...
