Objective of task 3.7.2 is the development and manufacturing of a suitable BMS hardware, including firmware, to ensure a hitchless and safe operation of the battery system from assembly until its end of life. Starting from a modular and scalable BMS architecture, which defines the required functionalities and features, suitable electronic components can be chosen and implemented into the battery system. A most widespread and state of the art BMS architecture is the master-slave-topology, where several slave boards are communicating in a daisy-chain with one master board. Since each slave board is monitoring one battery module, this topology is both modular and scalable, because adding one battery module will increase also the number of slave boards by one.
After the architecture is frozen, the needed electronic components can be developed according to the functional- and safety-requirements, which are necessary to achieve a marine certification. Starting from a suitable monitoring analog-front-end, which is the heart component of the BMS slave boards, a suitable wiring is developed. While setting up this wiring also the space for the slave boards inside the battery modules as well as the interfaces to the battery cells on the one hand and to the other slave boards or the master boards on the other hand have to be considered. Therefore, a close collaboration with the module design process (in task 3.4) is crucial to ensure a hitchless implementation of the BMS hardware into the battery system, e.g. the battery module housing.
As soon as the slave board electronics is finished, the master board, which holds the embedded BMS software, can be configured to control and communicate with the monitoring analog-front-ends on the slave boards. The embedded software contains the algorithms necessary to estimate battery states like state of charge, state of health or state of safety, which have to be adjustable in case updates are required due to further state of the art developments. Therefore, a cloud connection of the embedded software on the master board will be established, to send collected battery data from the master to the cloud on the one hand and performing updates of the BMS software from the cloud to the master board on the other hand.
