BATTERY CHAMBER OF HYBRID TUGBOAT
Document Type and Number:
WIPO Patent Application WO/2014/155520
Kind Code:
A1
Abstract:
Provided is a battery chamber capable of increasing the charge/discharge efficiency of a lithium ion battery while ensuring the safety of a ship and crew. A ship's hull (11) is equipped with a main engine (15) and an electric motor (18) as drive sources for driving a propeller. A lithium ion battery (31) for supplying electric power to the electric motor (18) is stored in a sealed battery chamber (20) separated and isolated from an engine chamber (14). The lithium ion battery (31) is charged by electric power supplied externally of the battery chamber (20). The battery chamber (20) is thermally shielded with heat insulation material from the outside of the ship, and the battery chamber (20) is provided with an indoor unit (42) of an air-conditioning device for adjusting the temperature inside the battery chamber (20). The temperature in the battery chamber (20) is adjusted by the air-conditioning device so as to enable the lithium ion battery (31) to provide the maximum charge/discharge performance.
