<p>A battery unit comprises a plurality of cells (1) and a smaller number of temperature sensors (5) adjacent thereto. Cells (1) without adjacent temperature sensors are connected to those with sensors to produce a mixed assembly. Heat collecting members (6) may be attached to the cells that do not have an adjacent sensor (5). The sensors may be PCT elements or thermistors. In another arrangement (figure 9) where all the cells have adjacent temperature sensors of the type which change in resistance with temperature, the sensors are divided into a plurality of blocks and in each block the sensors are connected in series. A temperature rise detecting circuit measures the resistance of each block and detects any abnormal temperature rise by comparing the resistance of the blocks of sensors with each other.</p> |
