Description

  The present invention relates to a storage battery package capable of feeding and charging.

2. Description of the Related Art In recent years, some transportation means such as ships are equipped with various facilities that effectively use energy generated in the ship. As an example, there is equipment for returning regenerative energy generated from a cargo handling device or rotating equipment installed in a ship to a power source (see Patent Documents 1 and 2). As another example, waste heat generated by a main engine such as a diesel engine is recovered, converted into electric energy, and reused in a ship (see Patent Document 3).
