Definitions

  • the switching elements are controllable and if the two-way circuits between the first and second accumulator cells are continuously produced alternately at predetermined time intervals such that every second accumulator cell is parallel to the first one in a first time interval Accumulator cell is connected and connected in a second time interval in parallel to the adjacent first accumulator cell. This results in a constant switching back and forth as regards the assignment of the cells of the strand 120 to the cells of the strand 110.
  • FIG. 2b shows the battery according to FIG. 1 in a second switching state
  • the method of alternately connecting the cells 121-124 includes i.a. the particular advantage that a charge balance in each operating condition of the battery (charging, discharging, rest and full load) is feasible.
  • the excess energy of individual cells is - without intermediate storage - redistributed to other cells and not converted into heat.
  • the here proposed balancing method is virtually lossless. Overloading of individual cells is in principle not possible with the method.
  • the battery and its circuitry in string 110 has no switching elements (MOSFETs, relays) in series, thereby achieving minimum internal resistance.
  • FIG. 3 shows the battery according to FIG. 1 in a state in which the cell 124 is separated from the strand 120 and separately connected to a measuring device M. This state is assumed during the operation of the battery during a measuring interval TO (see FIG. 4), wherein the switch positions A 'and B' do not correspond to the switch positions A and B during the measuring interval TO.
  • the cell 124 serves as a reference cell for a measurement for determining battery state variables.

Abstract

L'invention concerne une batterie (100) comprenant plusieurs éléments accumulateurs parmi lesquels N premiers éléments accumulateurs (111... 114) sont montés en série pour former au moins une branche d'éléments (110) et N deuxièmes éléments accumulateurs (121... 124) sont agencés de manière à pouvoir être connectés en parallèle respectivement à certains des N premiers éléments accumulateurs (111... 114) au moyen de N+2 éléments de commutation (131... 133', 134, 134'). L'invention vise à équilibrer la charge entre les éléments. A cet effet, les éléments de commutation (131... 133', 134, 134') sont conçus de manière à établir des montages à deux voies (A, B) entre les premiers et les deuxièmes éléments accumulateurs, chaque deuxième élément accumulateur (121) pouvant être connecté en parallèle alternativement à un premier élément accumulateur (111) à l'intérieur de la branche d'éléments (110) ou à un autre premier élément accumulateur (112) voisin de celui-ci. Les éléments de commutation (131... 133', 134, 134') sont de préférence commandables et établissent à intervalles de temps prédéfinis (TA, TB) en continu les montages à deux voies (A, B) entre les premiers et les deuxièmes éléments accumulateurs alternativement de sorte que chaque deuxième élément accumulateur (121) est connecté en parallèle au premier élément accumulateur (111) à un premier intervalle de temps (TA) et est connecté en parallèle à l'autre premier élément accumulateur voisin (112) à un deuxième intervalle de temps (TB).
