<p>795,330. Batteries. BOSCH GES., R. June 5, 1956 [June 8, 1955], No. 17281/56. Class 53. An accumulator is provided with two distinct sets of positive and negative plates in the same cell, the two sets being brought out to separate connections so that when it is desired to raise the temperature of the battery one set of plates can be short-circuited, the other set being used to supply current to the consuming device. The Figure shows a part of a 3-cell accumulator having positive plates 6 and negative plates 7. In each cell the three middle positive plates and the four adjacent negative plates constitute an independent subsidiary cell, these three cells being joined in series and having external positive and negative terminals 9, 10. The main battery is formed by the remaining plates in each cell, two negatives and two positives being situated on each side of the plates forming the subsidiary cell. The main cells are joined in series, the positive terminal being shown at 11 and the negative at 12. When the battery is to be warmed the terminals 9, 10 are shortcircuited. When it is to be charged the two sets of cells are joined in parallel and may remain so joined on discharge, being separated only when it is desired to pre-heat the battery.</p> |
