摘要

本文设计了一种3kW的电动汽车磁共振无线充电系统,并推导了其显式解。该系统的最大功率传输效率(PTE)可达90%以上。该系统通过调节占空比的方式,适应电池负载的动态变化,平衡发射线圈和接收线圈的电流。同时,充电功率和PTE也大大提高。

Modeling and analysis of a 3kW wireless charging system for electric vehicle
This paper designs a 3kW magnetic resonance wireless charging system for electric vehicles (EVs), and an explicit solution is derived. The maximum power transmission efficiency (PTE) is above 90% in this system. By the way of adjusting the duty ratio, this system adapts the dynamic change of the battery load and balances current of the transmitting coil and receiving coil. At the same time, the charging power and PTE are also greatly increased.
