System for powering auxiliary loads of an energy storage system

A power generation system, comprising:

• a power generation device;
• a bidirectional converter;
• a main bus configured to couple the power generation device to the bidirectional converter;
• a primary energy storage device operatively coupled to the main bus, the primary energy storage device located within a housing;
• an auxiliary bus operatively coupled to the main bus and a grid bus;
• a plurality of auxiliary loads configured to provide thermal support to the primary energy storage device to maintain an operating condition of the energy storage system;
• the plurality of auxiliary loads operatively coupled to the auxiliary bus;
• and
• the auxiliary bus is configured to supply power to the plurality of auxiliary loads from the primary energy storage device, the power generation device, a grid, or combinations thereof.

A method of providing power to a plurality of auxiliary loads of an energy storage system from a power generation device, a primary energy storage device, a grid, or combinations thereof, the method comprising:

• providing a first power to at least one of a rectifier and a first converter from at least one of the power generation device, the primary energy storage device, and the grid;
• converting, using at least one of the first converter and the rectifier, the first power to a second power;
• providing the second power to an auxiliary bus;
• and
• converting, using one or more auxiliary power conversion units, the second power on the auxiliary bus for use by the plurality of auxiliary loads of the energy storage system;
• and
• the auxiliary loads providing thermal support to the primary energy storage device to maintain an operating condition of the energy storage system.
