BATTERY TEMPERATURE MANAGEMENT

A battery and thermal management system, which has a battery and a heat transfer arrangement. An electrical terminal extends from each of the cells in the battery, and adjacent pairs of terminals are electrically connected together. The heat transfer arrangement has an inlet channel, an outlet channel, and a plurality of heat transfer channels. The heat transfer channels are defined between respective inflow walls and outflow walls, and extend between the inlet channel and the outlet channel. There is a permeable barrier in each heat transfer channel which is slanted, so that it is positioned furthest from the inflow wall at a first end of the heat transfer channel, and closest to the inflow wall at a second end of the heat transfer channel. Each permeable barrier is in thermal contact with a connected pair of terminals along a length of the permeable barrier,
