When multiple battery cells are packaged together in the same housing frame and linked to the outside through a uniform boundary, this makes up a battery module. It consists of a series-parallel combination of cells, the structure of which must play a role in supporting, fixing and protecting the cells.
Battery cycling is the operation by which a battery is tested over a period of time, through continuous charging/discharging. This process ages the battery cells and allows various parameters to be studied, to understand the phenomena at stake and estimate the duration of battery life.
An added advantage of this type of battery cycler architecture is that it optimizes workflow. Battery cycling involves the implementation and management of repetitive measurements to emulate the normal working conditions of a battery. Multiple channels help the user achieve this objective faster and more efficiently.
This is where battery modules come into play. Cells are initially connected and housed within frames to form these modules. Various battery assembly equipment are used to form packs from cells and provide an additional layer of protection, shielding cells from external factors such as heat and vibration.
The general principle of a battery cycler is fundamentally the same as a potentiostat / galvanostat. It is designed to apply a current and measure a voltage (galvanostatic mode) or the opposite function (potentiostatic mode). If they have impedance options, they can handle DC and AC signals.
A battery cell is basically comprised of an anode, a cathode, a separator and an electrolyte. The cell chemistry (and material used in the cell) is one of the main contributors to the cost of a battery system. The materials used in fabrication of battery cells can be nickel, iron, cadmium, lithium, etc. depending on the type of battery.
