Abstract
A hybrid light tower includes an engine, a generator configured to be driven by the engine, a battery pack, a mast, and a light assembly including a plurality of light emitting diodes. The generator is configured to produce a first DC power. The battery pack is directly electrically coupled to the generator to receive the first DC power from the generator to charge the battery pack. The light assembly is coupled to the mast and the light emitting diodes electrically coupled to the battery pack to receive a second DC power from the battery pack.
Claims20
A hybrid light tower, comprising:
- an engine;
- a generator configured to be driven by the engine, wherein the generator is configured to produce a first DC power;
- a battery pack directly electrically coupled to the generator to receive the first DC power from the generator to charge the battery pack;
- a mast;
- and
- a light assembly including a plurality of light emitting diodes, the light assembly coupled to the mast and the plurality of light emitting diodes electrically coupled to the battery pack to receive a second DC power from the battery pack.
A hybrid light tower, comprising:
- an engine;
- a generator configured to be driven by the engine, wherein the generator is configured to produce a first DC power;
- a battery pack directly electrically coupled to the generator to receive the first DC power from the generator to charge the battery pack;
- a mast;
- a light assembly coupled to the mast and including a plurality of light emitting diodes;
- and
- a controller in communication with the engine, the battery pack, and the light assembly, the controller being configured to selectively supply a second DC power to the plurality of light emitting diodes from the battery pack, the generator, or both the battery pack and the generator.
A method of controlling a hybrid light lower, the method comprising:
- receiving a first command from a user input;
- determining an engine status of an engine, a battery pack status of a battery pack, and a light status of a light assembly;
- calculating a desired power output for the light assembly based on the user input and at least one of the engine status, the battery pack status, or the light status;
- and
- supplying the desired power output to the light assembly using the battery pack, the engine, or both the battery pack and the engine.
