Abstract
Systems and methods for managing the temperature of an energy storage system are provided. In some embodiments, the energy storage system includes a housing, a first terminal, a second terminal, an energy storage element disposed within the housing, a thermal management system, and a controller. In some embodiments, the energy storage element are configured to electrically connect to a load or a grid via the second terminal. The thermal management system is configured to manage a temperature within the housing and also configured to receive power from an external power source via the first terminal.
Claims20
An energy storage system comprising:
- a housing;
- a first terminal;
- a thermal management system configured to manage a temperature within the housing, the thermal management system configured to receive power from an external power source via the first terminal;
- a second terminal;
- an energy storage element disposed within the housing, the energy storage element configured to electrically connect to a grid via the second terminal;
- and
- a controller coupled to the energy storage unit and the thermal management system.
A controller of an energy storage system comprising:
- a processor configured to:
- detect that the energy storage system is in a first state, the first state comprising the energy storage system configured to electrically provide or receive power to a grid via a second terminal of the energy storage system;
- in response to determining that the energy storage system is in the first state, electrically couple an energy storage element of the energy storage system to a thermal management system;
- detect that the energy storage system is in a second state;
- and
- in response to determining that the energy storage system is in the second state, electrically de-couple an energy storage element of the energy storage system from the thermal management system and electrically couple the thermal management system to a first terminal, the first terminal configured to relay power from an external power source to the thermal management system.
A method of controlling a temperature of an energy storage system comprising:
- determining, by a controller of an energy storage system, that the energy storage system is in a first state, the first state comprising the energy storage system configured to provide electrical power to a grid or load via a second terminal of the energy storage system;
- in response to determining that the energy storage system is in the first state, electrically coupling, via the controller, an energy storage element of the energy storage system to a thermal management system of the energy storage system;
- determining, via the controller, that the energy storage system is in a second state;
- and
- in response to determining that the energy storage system is in the second state, electrically coupling, via the controller, the thermal management system to a first terminal.
