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. The system may also be used to charge battery building blocks based upon their capacity and charging profile using an integral charger located within the energy storage system which is able to provide the requisite charge level and charging profile to respective battery building blocks. |
