Embodiment Construction

[0025]figure 1 A modularly constructed battery 100 is shown which comprises a plurality of battery cells 101 which can be constructed in the form of lithium-ion battery cells 101 , for example pouch cells. The modularly constructed battery 100 includes a hydraulic cooling device 10 for regulating the temperature of the battery 100 , which is also embodied for hydrostatically supporting the battery cells 101 . Furthermore, the battery 100 includes a detection unit 20 for detecting the operating states I, U, C, T, R, SOH, SOC of the battery 100 .

[0026] The battery cell 101 gradually ages during operation. This aging changes the properties of the battery 100 relevant to operation, such as the capacitance C, the internal resistance R, the self-discharge rate, the power supply capacity, the possible charging rate, the mechanical properties, and the like. Furthermore, this aging makes it possible for the battery cell 101 to exhibit an increase in thickness (so-called "swelling")...

Abstract

The invention relates to a battery of modular design and a method for operating a battery of modular design. The battery (100) of modular design has a plurality of battery cells (101) and a detectionunit (20) for detecting an operating state (I, U, C, T, R, SOH, SOC) of the battery (100). To this end, the invention provides an actuator (40) in order to set a pressure (P) in the battery (100) depending on the detected operating state (I, U, C, T, R, SOH, SOC) of the battery (100).

Description

technical field [0001] The invention relates to a modular battery and a vehicle with a corresponding modular battery. Furthermore, the invention relates to a method for operating a modularly constructed battery. Background technique [0002] Battery cells, such as lithium-ion battery cells, gradually age during operation. This aging changes the characteristics of the battery relevant to operation, such as capacity, internal resistance, self-discharge rate, power supply capability (Leistungs- ), possible charging rates, mechanical properties, etc. It is known that the process of cell aging can be influenced by applying mechanical force to the cell. In known batteries, the battery cells are often mechanically pretensioned to resist aging. Cells within a battery are often clamped under constant pressure. However, the clamped state of a battery cell may change as the cell ages, since the cell may exhibit an increase in thickness (so-called "swelling") with increasing use. ...
