Datacenter current injection for power management

A computer program product embodied in a non-transitory computer readable medium for datacenter power management, the computer program product comprising code which causes one or more processors to perform operations of:

• providing control for at least three power control modules (PCMs) and for current sensing devices for a datacenter power infrastructure unit;
• coupling to the controller at least three power control modules, wherein at least one of the at least three power control modules is connected to each phase of a three-phase datacenter power grid;
• sensing current for each phase of the three-phase datacenter power grid, wherein the current sense inputs are each coupled to the controller;
• and
• coupling at least three battery modules, wherein each battery module is coupled to a corresponding power control module, wherein the coupling provides an energy path between a battery module and each phase of the three-phase datacenter power grid, and wherein the coupling is managed by the controller.

A processor-implemented method for datacenter power management comprising:

• providing a controller for a datacenter power infrastructure unit;
• coupling the controller to at least three power control modules, wherein at least one of the at least three power control modules is connected to each phase of a three-phase datacenter power grid;
• sensing current for each phase of the three-phase datacenter power grid, wherein at least three devices for sensing current are each coupled to the controller;
• and
• coupling at least three battery modules, wherein each battery module is coupled to a corresponding power control module, wherein the coupling provides an energy path between a battery module and each phase of the three-phase datacenter power grid, and wherein the coupling is managed by the controller.
