Abstract
The present disclosure relates to an apparatus comprising a controller, a load, a battery, and a DC link. The DC link is coupled to the load, couplable to the battery, and couplable to an external power source. The load comprises an electrical component. The controller is configured to: evaluate a component startup criterion relating to whether the electrical component is performing a startup process, evaluate a source capability criterion relating to a capability of the external power source to supply power to the DC link, and in response to a determination, that the component startup criterion has been met and the source capability criterion has not been met, operate the apparatus in a protected startup mode in which the battery provides power to the DC link.
Claims17
An apparatus comprising controller circuitry, a load, a battery, and a DC link, wherein:
- the DC link is:
- coupled to the load,
- couplable to the battery, and
- couplable to an external power source;
- the load comprises an electrical component;
- and
- the controller circuitry:
- evaluating a component startup criterion relating to whether the electrical component is performing a startup process,
- evaluating a source capability criterion relating to a capability of the external power source to supply power to the DC link, and
- in response to a determination that the component startup criterion has been met and the source capability criterion has not been met, the controller circuitry causing the apparatus to operate in a protected startup mode in which the battery provides power to the DC link.
A transport refrigeration system comprising:
- an apparatus comprising controller circuitry, a load, a battery, and a DC link, wherein:
- the DC link is:
- coupled to the load,
- couplable to the battery, and
- couplable to an external power source;
- the load comprises an electrical component;
- and
- the controller circuitry:
- evaluating a component startup criterion relating to whether the electrical component is performing a startup process,
- evaluating a source capability criterion relating to a capability of the external power source to supply power to the DC link, and
- in response to a determination that the component startup criterion has been met and the source capability criterion has not been met, causing the apparatus to operate in a protected startup mode in which the battery provides power to the DC link,
- wherein the electrical component is configured to drive a compressor of the transport refrigeration system.
A method of operating an apparatus comprising a controller, a load, a battery, and a DC link, wherein:
- the DC link is:
- coupled to the load,
- couplable to the battery, and
- couplable to an external power source;
- and
- the load comprises an electrical component;
- the method comprising:
- evaluating, by the controller, a component startup criterion relating to whether the electrical component is performing a startup process,
- evaluating, by the controller, a source capability criterion relating to a capability of the external power source to supply power to the DC link, and
- in response to a determination that the component startup criterion has been met and the source capability criterion has not been met, causing, by the controller, the apparatus to operate in a protected startup mode in which the battery provides power to the DC link.
A method of operating an apparatus comprising a controller, a load, a battery, a DC link, and a power converter, wherein:
- the DC link is:
- coupled to the load,
- couplable to the battery, and
- couplable to an external power source via the power converter;
- and
- the load comprises an electrical component;
- the method comprising:
- evaluating, by the controller, a component startup criterion relating to whether the electrical component is performing a startup process,
- evaluating, by the controller, a source capability criterion relating to a capability of the external power source to supply power to the DC link, and
- in response to a determination that the component startup criterion has been met and the source capability criterion has not been met, causing, by the controller, the apparatus to operate in a protected startup mode in which the battery provides power to the DC link;
- the method further comprising, when operating the apparatus in the protected startup mode, controlling, by the controller, the power converter to maintain a current supplied to the DC link from the external power source within a target range.
