Abstract:

An electrochemical energy storage system is provided for an application having design energy and power requirements. The electrochemical energy storage system comprises first and second energy storage system components having different electro-chemistries and formed in different units. Said first energy storage system component includes a non-lead-acid battery adapted to provide the energy requirements of the application. Said second energy storage system component includes a lead-acid battery adapted to provide the power requirements of the application. Said first and second energy storage system components have a combined capacity that is less than a capacity of a mono-electrochemical energy storage system adapted to supply both the power and energy requirements of the application.
