To provide a filter cleaning apparatus of an electric vehicle capable of automatically cleaning clogging of a filter without exchanging the filter even when the clogging of the filter is generated due to accumulation (deposits) of foreign substance included in a cooling medium flowing through a cooling circulation path, whereby the foreign substance accumulated in the filter can be removed.SOLUTION: The filter cleaning apparatus of the electric vehicle includes: a filter cleaning path 26 that is branched from a cooling circulation path 14 through which a cooling medium for cooling a driving/generation-system device of an electric vehicle is circulated; a foreign substance collecting tank 28 that is disposed on the filter cleaning path and removes foreign substance included in the cooling medium flowing through the filter cleaning path; and a filter cleaning control device 60 that controls the flow of the cooling medium so as to remove the foreign substance accumulated in a filter 16 provided to the cooling circulation path, and to cause the removed foreign substance to flow together with the cooling medium to the foreign substance collecting tank.SELECTED DRAWING: Figure 1
【課題】冷却循環経路を流れる冷却媒体中に含まれる異物が、フィルタに集積(堆積)して、フィルタの目詰まりが発生しても、フィルタの目詰まりを、フィルタを交換することなく、自動的に清掃して、フィルタに集積した異物を除去することができる電動車両のフィルタ清掃装置を提供する。【解決手段】電動車両の駆動・発電系装置を冷却する冷却媒体が循環される冷却循環経路14から分岐したフィルタ清掃経路26と、フィルタ清掃経路に配置され、フィルタ清掃経路を流れる冷却媒体中に含まれる異物を除去する異物捕集タンク28と、冷却循環経路に設けられたフィルタ16に集積した異物を取り除き、取り除かれた異物を冷却媒体とともに異物捕集タンクに流すように冷却媒体の流れを制御するフィルタ清掃制御装置60と、を備えることを特徴とする。【選択図】図1
