The International Maritime Organization referred to the reduction of carbon emissions of all ships with the strengthening of emission restriction on greenhouse gases and air pollutants(NOx, SOx, PM), set up a strong goal that reduce carbon emissions by 10% in 2015, and will continue to do that, on into the future.
Today, to reduce those emissions, ‘green ship’, such as hybrid or electric propulsion vessels powered by large batteries are being built.
And therefore, it is necessary to manage batteries more strictly, because they have getting wider usages enough to be used as a power source for hybrid ship and electric propulsion ship.
Hybrid ship has power supply units connected to the packets to produce more than 500kWh large power source, and therefore, A number of the communication modules and wires need to implement the wire inspection and monitor system that allows monitoring server to transmit detecting voltage, current and temperature data, which is required for the management of the batteries.
This paper proposes a remote monitoring system of lithium batteries for green ship using BLE wireless communication modules and power line modem.
