Hybrid light tower

A hybrid light tower, comprising:

• an engine;
• a permanent magnet generator configured to be driven by the engine, wherein the generator is configured to produce a DC power;
• a battery pack including a plurality of lithium-ion battery cells;
• a mast;
• a light assembly including a plurality of light emitting diodes, the light assembly coupled to the mast and the light emitting diodes electrically coupled to the battery pack to receive power from the battery pack, the generator, or both the battery pack and the generator;
• and
• a controller in communication with the engine, the battery pack, and the light assembly, the controller being configured to:
• receive an available power output from the battery pack;
• determine if the available power output is less than a commanded power consumption of the light assembly;
• and
• upon determining that the available power output is less than the commanded power consumption of the light assembly, instruct the engine to increase speed and thereby increase the DC power provided by the generator.

A hybrid light tower, comprising:

• an engine;
• a permanent magnet generator configured to be driven by the engine, wherein the generator is configured to produce a first DC power;
• a battery pack including a plurality of lithium-ion battery cells, the battery pack directly electrically coupled to the generator to receive the first DC power from the generator to charge the battery pack;
• an extendible mast configured to move between a lowered position and a raised position;
• 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 light emitting diodes from the battery pack, the generator, or both the battery pack and the generator.
