  • Energy storage unit in conjunction with second electrical energy storage units and corresponding device, computer program and machine-readable storage medium
  • the present disclosure describes a method for determining the ambient temperature of a first electrical energy storage unit, which is in a network with second electrical energy storage units.
  • Electrical energy storage units in particular battery cells or electrical energy stores constructed from the same, show a strong dependency of their performance, i.e. in particular their current-carrying capacity or current-carrying capacity, their temperature.
  • the permissible electrical current drops sharply when the current is supplied or in particular when the current is drawn at temperatures of around or below 0 ° C.
  • An amperage that is higher than the permissible level thus frequently leads to damage to an electrical energy storage unit, for example lithium plating - the unwanted deposition of lithium - which cannot be reversed.
  • Compliance with the permissible current strengths is therefore an important requirement when operating electrical energy storage units.
  • the permissible current strengths can have a dependence on the temperature of the electrical energy storage units in order to take into account the temperature dependence of the performance.
  • the temperatures of the further electrical energy storage units in the network are optionally determined using mathematical models and methods. Since the mathematical models typically model heat exchange processes, knowledge of an ambient temperature of the corresponding electrical energy storage unit is required for precise mathematical modeling. If there is no knowledge of the ambient temperature, the temperatures of the other electrical energy storage units can only be estimated imprecisely. It is therefore necessary that their respective current limits have a corresponding safety buffer, as a result of which the entire performance of the further electrical energy storage units cannot be called up.
  • the electrical energy storage units are usually oversized.
  • a larger electrical capacity of the electrical energy storage units or a different type of cell, for example with different cell chemistry, may be required.

  • an ambient temperature of the surroundings of the first electrical energy storage unit is determined as a function of the temperature of the first electrical energy storage unit and the temperature difference.
  • An electrical current strength of an electrical current flowing into or out of the first electrical energy storage unit is expediently determined and compared with a predefined threshold value, with the reaching and / or falling below the predefined threshold value by the Current intensity at least determining a temperature of the first electrical energy storage unit and determining the temperature difference between the first electrical energy storage unit and its environment. This is advantageous because the ambient temperature can be determined more precisely under these conditions.
  • the predefined threshold value is advantageously between 0 A and 10 A, preferably between 0 A and 5 A, particularly preferably between 0 A and 1 A.

  • power electronics are controlled, the current limits being set as a function of the average temperature of the further electrical energy storage unit.
  • Such power electronics can be an inverter, for example. This is advantageous since the current limits can be set more precisely, that is to say less conservatively - with less safety reserve - as a function of the determined ambient temperature, as a result of which a higher power output or power consumption is possible. This is particularly relevant for applications of electrical energy storage units in which they have to consume a lot of power in a short time, for example in so-called boost recuperation systems based on 48V.

  • the temperature difference between the first electrical energy storage unit and the surroundings of the first electrical energy storage unit is expediently determined as a function of a constant, the constant representing the ratio of a heat capacity of the first electrical energy storage unit to a thermal resistance of the first electrical energy storage unit.
