In this study, simulations and experiments on wireless power transfer (WPT) in a multi-coil environment are conducted under the conditions of multiple battery charging. A series-arrayed 4-coil system comprising one WPT system and three identical WPT systems placed in parallel are investigated in this work. We show that low-frequency wireless power transfer is affected by multiple coils placed in parallel within a confined area. The power transfer efficiency at low frequencies can be degraded by 20% as compared to that of a single WPT system.
