Abstract
The present invention provides an energy storage system that utilizes batteries of multiple compositions and provides improved load sharing between the different types of batteries is disclosed. The energy storage system includes at least two batteries, where each battery has a different chemical composition for storing energy. One battery is configured for rapid charging/discharging and the other batter is configured for slower charging/discharging. Each battery is connected to a common connection via an energy regulator. The regulators are initially configured such that the energy regulator connected between the common connection and the battery configured for rapid charging/discharging responds initially to changes in power demand at the common connection. If power demand continues, the first regulator decreases the amount of energy transferred between the first battery and the common connection while the second regulator begins transferring energy between the second battery and the common connection.
