Description

Angle measuring and calculating and angle resetting device and method Technical Field The invention relates to the technical field of electric vehicle battery replacement, in particular to an angle measuring and calculating and angle resetting device and method. Background With the vigorous development of the electric automobile market, consumers are increasingly pressing the demands for improving the endurance mileage of the vehicle and shortening the charging time. Under the background, the electricity conversion technology is gradually becoming an important way for solving the problem of continuous voyage anxiety and acceleration of charging efficiency of the electric automobile as an innovative energy supply mode. The chassis power conversion technology takes the dominant position in the market due to the characteristics of high efficiency and convenience. The core of the chassis power exchange technology is an efficient battery exchange process between the vehicle and the power exchange station. In particular, when an electric vehicle enters a battery exchange station, a battery (or a battery compartment) at the bottom of the vehicle can be smoothly unlocked and released from the bottom of the vehicle by guiding and positioning. Then, the transfer trolley rapidly receives the battery (or the battery bin), and conveys the battery (or the battery in the battery bin) to a battery changing cabinet in the battery changing station for charging or storing, and simultaneously, takes out a fully charged battery from the battery changing cabinet for reverse installation. However, although the chassis power conversion technology has great application potential, a key challenge is still faced in actual operation, namely, parking accuracy. Because the parking of the vehicle in the power exchange station often is difficult to reach a complete standard angle, the tiny angle deviation is obviously amplified in the power exchange process, so that when the transfer trolley tries to load the battery into the power exchange cabinet or load the full-power battery back to the bottom of the vehicle, the exchange cannot be successfully completed due to the fact that the angle deviation of the battery cannot be accurately aligned, and further the power exchange efficiency and the user experience are affected. Of course, such a problem is not limited to a single field of battery replacement, and in real life, there is a possibility that accurate transportation may not be performed due to angular deviation as long as the transportation is involved.
