A battery is a device that converts chemical energy into electrical energy. It consists of one or more electrochemical cells, which are connected in series or parallel to increase the voltage or current output. A battery schematic diagram is a graphical representation of how the various components are connected within the battery.
In a battery schematic diagram, the electrolyte is represented by an arrow or a dashed line. It plays a crucial role in conducting ions and facilitating the chemical reactions that generate electrical energy. The separator is a component that physically separates the anode and cathode of a battery while allowing the flow of ions.
The design solutions are assessed from an assembly, disassembly and modularity point of view to establish what solutions are of interest. Based on the evaluation, an “ideal” battery is developed with focus on the hardware, hence the housing, attachment of modules and wires, thermal system and battery management box.
When designing a battery pack, it is important to weigh different parameters against each other to acheive a suitable design. It is therefore significant for these tradeoffs to have a valid foundation to stand on. One tradeoff that needs to be accounted for is comparing safety of the battery against its weight.
All battery housings are assembled using screws which is beneficial for the disassembly since it is possible to remove the lid without damaging it. However, a large amount of screws is needed, making it a time-consuming activity and an increased number of parts results in longer lead times as well as higher material usage.
Working principle: The battery schematic diagram illustrates the movement of electrons and ions during the battery’s operation. The chemical reactions occurring at the anode and cathode generate a flow of electrons, resulting in an electric current.
