Patent number: 10193357Abstract: An energy storage system having battery building blocks which contribute load current to the output of the energy storage system. A system controller provides functional control of the energy storage system and communication to an external host, a system charger charges cells in the battery building blocks and an interface provides a separate connection for at least two battery building blocks to allow the at least two battery building blocks to be separately removed from the energy storage system. The system controller diverts the flow of current from a charger to provide a contribution to the load current in place of the contribution to the load current from the battery building block being replaced to allow said battery building block to be replaced whilst the energy storage system is in operation.Type: GrantFiled: June 24, 2014Date of Patent: January 29, 2019Assignee: TWS (MACAU COMMERCIAL OFFSHORE) LIMITEDInventor: Peter Marinov

Patent number: 9899853Abstract: A portable alternating current power supply assembly which has an extendable operational period and which provides an external power supply for a tool. It has a power inverter and a removable battery unit which is connectable to the power inverter by a coupling to form the power supply and which when so connected forms a discrete unit. A DC output from the removable battery unit is converted to a pure sine wave AC output from the power supply assembly by the power inverter. The power inverter is separable from the battery unit to provide an operational period for the power supply assembly which is equivalent to that which might be provided using larger AC power supplies which have larger DC voltage batteries and which are part of a sealed unit with the power inverter.Type: GrantFiled: March 20, 2014Date of Patent: February 20, 2018Assignee: TWS (MACAU COMMERCIAL OFFSHORE) LIMITEDInventors: Peter Marinov, Dominic Reilly

Patent number: 9787108Abstract: A battery management system and a method for enhanced battery management of a battery containing a number of cells. The method and system measures the cell capacity of two or more of said cells, ranks the cells in order of their cell capacity values and calculates a value for a cell specific supporting current for the measured cell, for a given load, based upon the ranked cell capacity values. Calculated cell specific currents are then provided to the cells.Type: GrantFiled: November 1, 2013Date of Patent: October 10, 2017Assignee: TWS (MACAU COMMERCIAL OFFSHORE) LIMITEDInventor: Mark Wayne Huggins
