Lithium-ion battery system for use in battery-powered ships/offshore platforms and hybrid applications.
The battery system consists of one or more battery packs connected in series to a PDU switchbox.
Multiple systems can be connected in parallel to gain more capacity and redundancy.
Packs up to a voltage limit of 1000 V can be connected in series. Three pack sizes are defined.
A battery pack consists of LiFePo4 cell modules, MMU slave, MSD fuse, HV sockets, LV sockets and the temperature protection of the second level protection. The PDU consists of BMU master, HV contactors, HV sockets, LV sockets, MSD fuse. Internal communication between packs and PDU is solved by a master-slave concept.
The size of the battery system is limited by the number of cells in the system. The maximum configuration is 240 cells connected in series.
A mixture of A, B and C packs increases the system voltage from 77V to up to 768V nominally.
We are happy to advise you and help you from the idea to the finished battery.
