PROBLEM TO BE SOLVED: To provide an inter-vehicle power reception/supply device 1 for improving a coast distance of a power receiving vehicle 20 by suppressing a power loss at power reception and supply with respect to the power receiving vehicle 20.SOLUTION: In an inter-vehicle power reception/supply device 1 having a motor generator 11, an on-vehicle battery 12, power reception/supply means for receiving and supplying power between a convoy-traveling power receiving vehicle 20 and itself, and charge/discharge control means for controlling the charge/discharge of the on-vehicle battery 12, the inter-vehicle power reception/supply device also comprises: an input/output characteristic map 17a of a power supply vehicle 10; target temperature calculation means for calculating a battery temperature T2 at which the output density of the on-vehicle battery 12 becomes substantially the same as the current input density W2 of an on-vehicle battery 23 on the basis of the input/output characteristic map 17a of the power receiving vehicle 20 as a target temperature; and preheating means for preheating the on-vehicle battery 12 until the battery temperature reaches the target temperature when the output density W1 of the on-vehicle battery 12 is lower than the input density W2 of the on-vehicle battery 23.SELECTED DRAWING: Figure 2
【課題】受電車両20との受給電における電力の損失を抑えて、受電車両20における航続距離の向上を図る車々間受給電装置1を提供することを目的とする。【解決手段】モータ兼発電機11と、車載バッテリ12と、隊列走行している受電車両20との間で受給電する受給電手段と、車載バッテリ12の充放電を制御する充放電制御手段とを備えた車々間受給電装置1であって、給電車両10の入出力特性マップ17a、及び受電車両20の入出力特性マップ17aに基づいて、車載バッテリ12における出力密度が、車載バッテリ23における現在の入力密度W2と略同等になるバッテリ温度T2を目標温度として算出する目標温度算出手段と、車載バッテリ12の出力密度W1が、車載バッテリ23の入力密度W2よりも低い場合、バッテリ温度が目標温度になるまで車載バッテリ12を予熱する予熱手段とを備えたことを特徴とする。【選択図】図2
