Abstract
A battery module is provided for a battery system including at least two battery modules, where each battery module is provided with a module monitoring unit arranged to monitor at least one performance related parameter for each secondary cell in the battery module. Parameters relating to the performance for each battery module are stored in a memory on the respective module monitoring unit. An energy storage system with a battery pack including such a battery monitoring unit for monitoring the battery pack and a modular system of battery packs, each including at least two replaceable, interchangeable battery modules is also provided. The energy storage system can further include super- or ultracapacitor modules.
