This work will demonstrate the performance of a battery energy storage system (BESS) designed for long duration energy storage thorough time-shifting photovoltaic (PV) power production in Nordic climate. The BESS has an energy capacity of 300kWh, a power capacity of 100kW, and the cells are of NMC-type in pouch-format. All components are installed in a […]

This work aims to take a deeper look at the feasibility of using pulses to estimate the impedance spectrum of a battery module, which consists of several battery cells in series. Regarding the existing literature, there are two main aspects we wanted to explore. One is to have high speed voltage and current measurements with […]

To maintain losses and cooling efforts of growing capacity and power rating of battery energy storage systems the battery system voltage will have to be increased significantly. Hence novel high voltage battery energy storage systems (HV-BESS) are the subject of development in various cases with high power demands in mobile and static applications. In contrast […]

Typical behind-the-meter (BTM) services leave unused flexibility. Literature lacks applicable methods to activate additional revenue streams while still delivering BTM applications. This work presents a real-time controller to identify available flexibility during BTM operation and models an interface to a trading entity. We quantify revenue potentials based on order book data and load measurement from […]

LiFePO₄ (LFP) cathode is one of the most widely used cathode materials in commercial lithium-ion batteries due to its excellent thermal stability, long cycle life, and safety. However, its relatively low specific capacity limits the energy density of cells utilizing this material. To address this limitation, replacing the conventional graphite anode with prelithiated silicon oxide […]

The current transformation of the automotive sector, particularly through electrification, poses numerous challenges. In particular, the availability of a skilled workforce and thus the qualification of employees will be a key challenge for industry. This transformation could result in an estimated 300,000 to 1 million jobs in Europe by 2030 in the areas of battery […]

Ultrasonic measurements offer insights into cell behavior and aging during cycling. For the Graphite/NMC cell tested, the ToF consistently increased during charging and decreased during discharging likely due to changes in density and Young’s modulus of the graphite anode. A two-week cycling pause at cycle 100 led to a temporary drop in ToF, followed by […]

With the decentralization of renewable energy sources, multi-energy systems (MES) integrating the electrical sector with mobility or thermal sectors are increasingly preferred for their sustainability and flexibility. However, optimizing such complex systems is challenging, requiring a balance of profitability, asset aging reduction, and sustainability. This study examines a real-life MES setup for residential buildings housing […]
