Description

A high power bipolar battery, such as a high power lithium polymer battery is provided. The bipolar battery includes a plurality of multiple cell assemblies. The plurality of multiple cell assemblies is connected in series to form the high power bipolar battery. Each of the plurality of multiple cell assemblies includes a rigid core with a bipolar cell stack of multiple cells wound together around the rigid core to produce a large active cell area. The wound bipolar cell stack includes a positive battery connection and a negative battery connection. A container surrounds the bipolar cell stack. A positive terminal carried by the container is connected to the positive battery connection. A negative terminal carried by the container is spaced apart from the positive terminal and connected to the negative battery connection. A state-of-charge connector carried by the container is spaced apart from the positive and negative terminals. The state-of-charge connector include multiple conductors, each connected to a respective one of the multiple cells.
