Description

Technical Field

[0001] The present invention relates to the field related to electric vehicles, and in particular to a precise proximity control system for a wireless charging transmitter plate and a control method thereof. Background Art

[0002] A battery electric vehicle (BEV) is a vehicle that uses an onboard power source, an electric motor to drive its wheels, and complies with all road traffic and safety regulations. Electric vehicle charging methods are categorized into two main types: wired charging and wireless charging. Wireless charging, or contactless charging, involves installing a wireless charging transmitter on the ground and a receiver board on the underside of the vehicle. To charge, the vehicle is parked over the transmitter, aligning the receiver board with the transmitter. The transmitter emits electromagnetic waves, which the receiver board receives and converts into electrical current, resulting in charging. Wireless charging is gaining increasing acceptance due to its ease of use.

[0003] Existing ground-mounted wireless transmitter chargers can adjust their lifting height according to vehicle needs, but their internal limit switches have low sensitivity and cannot recognize sudden and drastic changes in distance information. If the wireless charger is crushed by someone or other circumstances during the ascent process, causing the height of the wireless charger to change drastically, the limit switch will fail, resulting in an uncontrolled ascent process and easily causing damage to the charger.
