The AFC West side reached the divisional round of the playoffs this season, but will be looking to strengthen the roster in the off-season in order to progress further in the 2014 season.
The Chargers' vice-president of football operations told the team's official website: "When we come back to San Diego, we have a lot of work ahead of us.
"The scouting combine is next month and we'll have a lot of personnel type meetings before the combine. And we'll be getting ready for free agency. The new league year starts in March and that is when free agency begins.
"So we have a lot of work to do before now and then. They have been ongoing processes and we have done a lot of work on them already, but now we are in the final period of time before they begin so we are continuing to do more."
The Chargers missed the post-season for three campaigns in a row prior to this year's success.
