  • Publication number: 20240333015
    Abstract: A method for compensating for the internal resistance of an energy storage device, in particular an exchangeable replaceable battery pack, comprising at least one energy storage cell, in which the internal resistance is compensated for in an electric consumer or charging device, which is connected to the energy storage device, on the basis of an exponentially declining approximation, the curve of which depends on the temperature and the cell chemistry of the at least one energy storage cell. A system includes at least one energy storage device designed as an exchangeable replaceable battery pack and an electric consumer for discharging the exchangeable replaceable battery pack and/or a charging device for charging the exchangeable replaceable battery pack. The exchangeable replaceable battery pack, the electric consumer, and the charging device each has an electromechanical interface with a plurality of electric contacts for performing the method.

  • Patent number: 11500036
    Abstract: A method for recognizing contacting errors in a rechargeable battery pack. Each rechargeable battery of the rechargeable battery pack is connected in parallel to at least one further rechargeable battery of the rechargeable battery pack. The method includes: applying at least one current to the rechargeable battery pack; ascertaining at least one voltage that is present at the rechargeable battery pack, as a function of the applied current; determining at least one parameter based on the ascertained voltage; and comparing the parameter to a comparison variable.

  • Patent number: 10336209
    Abstract: The present invention relates to a method and a device for operating a battery, in particular a lithium ion battery, in a load. For this purpose, a determination (S10) is carried out of at least one operating parameter which describes the state of the battery or the load, a comparison (S20) of the at least one determined operating parameter with one reference value in each case in order to recognize whether a predefined state exists, and a discharge (S32) of the battery until the charge state of the battery lies below a specified critical charge state of the battery if it has been identified that the predefined state exists, wherein by discharging the battery, an energy store is charged by a discharge flow from the battery.
