The EU Hybrid Marine (HYMAR) project is an ICOMIA led collaborative research project funded under the EU’s Seventh Framework Research Programme (FP7)
High power density, durability and affordability are essential features of marine hybrid batteries. Enersys are developing a new range of long life, deep cycle batteries for hybrid applications
To carry out the research, development and testing necessary to produce a cost-effective energy storage device (thin plate pure lead battery – TPPL) optimised for the specific needs of a marine hybrid drive system, including high discharge and recharge rates, low internal resistance and heat production, high discharge/recharge efficiency, the ability to cycle in a partial state of charge, and high cycle life
To deliver sufficient prototype TPPL batteries to the test boat for validation at sea
To determine the optimal battery management strategy
To increase the lifetime kWh energy output by a minimum of 50% as compared to the best of conventional lead acid technology.
To increase the number of charge/discharge cycles by a minimum of 50% as compared with the current state of the art
To optimise the battery charge/discharge characteristics in order to keep the generator loaded at its optimum point and achieve a minimum 5 year battery life
