Description

Technical Field

[0001] The present invention relates to the field of battery replacement technology, and in particular, to a fully automatic guidance method for vehicle battery replacement. Background Art

[0002] In recent years, with the rise in global oil prices and increasingly stringent automobile emission standards, the development of domestic new energy vehicles has ushered in a trend of sustained rapid growth, and the market share has steadily increased. According to the latest data released by the China Association of Automobile Manufacturers: In June 2023, the production and sales of new energy vehicles were 784,000 and 806,000 respectively, an increase of 9.9% and 12.5% ​​month-on-month, and an increase of 32.8% and 35.2% year-on-year respectively. From January to June 2023, the production and sales of new energy vehicles were 3.788 million and 3.747 million respectively, an increase of 42.4% and 44.1% year-on-year respectively. Against the background of the rapid increase in the number of new energy vehicles, it is difficult to meet the huge demand for energy replenishment by traditional charging methods alone, and the charging methods have bottlenecks such as long energy replenishment time and inflexibility, which have been criticized by new energy vehicle owners. Although there are 1000V high-voltage fast charging on the market, which can shorten the energy replenishment time, new technologies often take time to verify and improve. In the current context, the battery swap model has emerged as the times require, becoming an important way to shorten the time it takes to recharge new energy vehicles and reduce the pressure on the power grid when many vehicles are recharging. The battery swap station can charge the vehicle when the power grid electricity price is at its valley point, and return the electricity to the grid when the power price is at its peak point, which has the effect of shaving the peak and filling the valley and reducing the pressure on the power grid.

[0003] How to park the vehicle accurately at the battery swap station so that the battery swap components can swap its battery has become one of the difficult problems to solve. At present, two methods are commonly used in the industry. One is to attach a label to the vehicle and use a laser locator to shine on the label or use a speed bump for positioning. This solution can only ensure the accuracy of the forward direction, but cannot ensure that the vehicle does not tilt, and the driver cannot judge whether the vehicle position meets the hoist grabbing position. He can only wait for the equipment to start and the gantry camera to take pictures to confirm. If it does not meet the grabbing conditions, the driver can only drive the car out and re-enter until the grabbing conditions are met. The second is to install a camera on the top of the battery swap channel, and display the real-time image of the camera at the channel, mark the area that meets the hoist grabbing area in the picture, and guide the driver to change the vehicle position in real time to meet the battery swap conditions. This solution requires an additional camera, which is costly. Summary of the invention
