Definitions

  • the invention relates to a method and a device for charging of rechargeable batteries, which consist of a series circuit of single-cell arrangements each comprising one or more parallel-connected individual cells, according to the preambles of claims 1 and 4.
  • Batteries with a high nominal voltage consist of a series circuit of single-cell arrangements of one or more individual cells connected in parallel, each having only nominal voltages in the single-digit volts range.
  • the invention has for its object to provide a method and apparatus for charging PHg of batteries, which consist of a series connection of single cell arrangements of one or more parallel single cells, which simplifies monitoring of single-cell arrangements and prevents overcharging.
  • the single cell arrays can be charged to their respective rated voltage or up to 80% of their maximum capacity.
  • the single-cell arrangements can be charged at least partially with a time delay.
  • the chargers may include switched mode power supplies. As a result, electrical losses of the chargers are minimized.
  • the switching power supply chargers are commercially available mass-produced goods with a performance in the 100 watt range.
  • a battery 10 from a series circuit of single cell arrangements Z 1 ... Z N and chargers L 1 ... L N and a control circuit 12 are shown.
  • the individual cell arrangements Z 1 ... Z N each consist of a plurality of parallel-connected single cells 14 based on lithium ions.
  • Lithium-ion batteries are characterized by a high energy density and low self-discharge and have no memory effect.
  • the capacity loss during the operating time depends on the age, the operating and ambient temperature and the state of charge. In order to minimize the capacity loss, a charge state between 40% and 80% of the maximum charge should be aimed for, which can be achieved by short charging cycles.
  • the nominal voltage of the single cells 14 depends on the cathode material and is between 3.3 and 3.8 volts, in conventional lithium-ion batteries at 3.6 volts.
  • the nominal voltage of the single cells 14 depends on the cathode material and is between 3.3 and 3.8 volts, in conventional lithium-ion batteries at 3.6 volts.

  • the chargers L 1 ... L N comprise switched-mode power supplies whose power is dimensioned for the charging power of the single-cell arrangement Z 1 ... Z N.
  • the switching power supplies are on the primary side a supply source 16, z. B. household electricity, wind or solar generator connected.
  • the chargers L 1 ... L N in turn are controlled by the control circuit 12 via control lines S 1 ... S N.
  • the chargers L 1 ... L N are offset in time or activated simultaneously. If no three-phase power connection is available for a high charging power, alternatively two or more separately fused single-phase household sockets with 230 V voltage can be used, to which separate charging boxes with separate chargers are connected. With three 16 A fuses, a maximum of approx. 10 kW of charging power could then be used.
  • the control circuit 12 monitors the state of charge of the single-cell arrangement Z 1 ... Z N and regularly terminates the charge as soon as the nominal voltage of the individual cells 14 or 80% of the maximum charge has been reached. In the event that the battery 10 is immediately discharged again during operation following the charging process, the single-cell arrangements Z 1 ... Z N can also be charged up to their charge-end voltage of approximately 4 r 2 V.
  • the control circuit 12 monitors the state of charge of the individual cell arrangements Z 1 ... Z N and regularly interrupts the discharge as soon as the charging state of the individual cell arrangements Z 1 ... Z N reaches 40% of the maximum charge.
  • the individual cell arrangements Z 1 ... Z N can however also be discharged to their discharge final voltage of approximately 2.5V.

Abstract

L'invention concerne un procédé et un dispositif pour charger des accumulateurs. Lorsque les accumulateurs constitués de systèmes de cellules individuelles composés respectivement d'une ou plusieurs cellules individuelles montées en parallèle, lesdits systèmes de cellules individuelles étant reliés en série, sont chargés, chaque système de cellules individuelles monté en série est chargé par son propre chargeur d'accumulateur, qui est séparé de manière galvanique des autres chargeurs d'accumulateurs.
