To arrange a control device relaying communication between a battery pack and a vehicle control device at an appropriate position in a vehicle mounted with a replaceable battery pack.SOLUTION: An electric vehicle 100 comprises: a battery pack 10 including a battery ECU; a gate ECU 60 which is installed separately from the battery pack 10; and an HVECU 50 which is installed separately from the battery pack 10 and the gate ECU 60 and controls either battery power or battery current of the battery as a control object. The gate ECU 60 is positioned outside the battery pack 10 and relays communication between the battery ECU and the HVECU.SELECTED DRAWING: Figure 5 【課題】交換可能な電池パックを搭載した車両において、電池パックと車両の制御装置との間の通信を中継する制御装置を適切な位置に設置する。【解決手段】電動車両１００は、電池ＥＣＵを含む電池パック１０と、電池パック１０とは別個に設けられたゲートＥＣＵ６０と、電池パック１０およびゲートＥＣＵ６０とは別個に設けられ、バッテリの電池電力及び電池電流のうちのいずれか一方を制御対象として制御するＨＶＥＣＵ５０とを備える。ゲートＥＣＵ６０は、電池パック１０の外部の位置に設置され、電池ＥＣＵとＨＶＥＣＵとの間の通信を中継する。【選択図】図５
