Mata-ni-Bula pte Ltd are developing a 48V 120Ah (6.6kWh) scalable battery module based on lithium–ion technology. The battery will have built in Battery management system with a user friendly interface that can be customized for market sector requirements. The battery can be scaled to over 1 MW in capacity. Other products will include a 28V version and possibly and a 12V economy version.
The basic design is based on a series – parallel combination of small cylindrical cells. Each cell is fused to the battery system, thus when a cell develops a fault, the fuse will blow, and remove the faulty cell from the system, without disabling the entire battery – such as would happen with a large capacity prismatic cell, or with the typical lead acid battery – which often exhibits shorted cells towards the end of life. A battery management system is integrated, and provided with RS485, CAN bus or Bluetooth / WiFi interface, thus enabling the battery status to be viewed on a smart phone, or commented to a vessel or building energy management system. Interfaces can be customised for larger systems.
The basic modules can be connected in series to give higher voltages , and in parallel to give added capacity. The BMS systems will interconnect to a master unit, thus giving a single point of communication for large battery systems.
The battery systems will be locally serviceable, allowing capacity to be maintained at a lower cost than replacement of the entire battery.
