To suppress the lowering of charge efficiency at convoy traveling.SOLUTION: A power transmission system comprises: a power transmission/reception part for transferring the power of a battery in a non-contact manner between vehicles performing convoy traveling in which a plurality of the vehicles (vehicles 10a, 10b, 10c and 10d) travel in line; and a power transmission control part for acquiring an empty vehicle which can be battery-charged at vehicle-outside charging equipment out of the plurality of vehicles which perform the convoy traveling, and transmitting and receiving the power between the vehicles which perform the convoy traveling so that an SOC of the battery of the vehicle corresponding to the empty vehicle out of the number of the vehicles is equalized.SELECTED DRAWING: Figure 3 【課題】隊列走行の際の充電効率の低下を抑制する。【解決手段】電力伝送システムは、複数の車両（車両１０ａ、１０ｂ、１０ｃ、１０ｄ）が列をなして走行する隊列走行を行う車両間で、バッテリの電力の授受を非接触で行う送受電部と、隊列走行を行う複数の車両のうち、車外の充電設備においてバッテリの充電を行うことが可能な空き台数を取得し、空き台数に応じた車両台数の車両におけるバッテリのＳＯＣを平準化するように、隊列走行を行う車両間で送受電を行わせる電力伝送制御部と、を備える。【選択図】図３
