BATTERY CELL SIMULATOR THE VIRTUAL BATTERY The comemso battery cell simulator – the all-in-one battery management system test and development solution for (mobile) energy storage systems. BATTERY CELL SIMULATOR BATTERY CELLS NEED CONSTANT MONITORING Electromobility is growing at a tremendous rate worldwide. For today’s mobile energy storage systems, that means they not only have to deliver high performance, they also need to ensure safe, reliable operation. Doing so requires constantly monitoring the voltage and temperature of every single battery cell. This is done with a special...

BATTERY CELL SIMULATOR VIRTUAL BATTERY In active balancing, charge is exchanged among the battery cells, a process that is controlled by the BMU. In this process, energy is transferred from cells that are already fully charged to those neighboring battery cells that have not yet reached their SoC. There are three methods: a) semiconductor switching (e.g. matrix with transistors), b) capacitive charge transfer, and c) inductive charge transfer. in the battery cell simulator: Since all of their electrical characteristics can be parameterized, they can simulate all required states and faults...

BATTERY CELL SIMULATOR BATTERY CELL SIMULATOR FOR THE HIGHEST STANDARDS A battery cell simulator (BCS) must be capable of performing functional verification for many different aspects of a modern BMS and needs to provide high-precision voltage regulation even at high balancing currents so that it can accurately emulate the state of charge of a battery cell. It also needs well-matched hardware and software controls for high accuracy, with lean control algorithms that allow no overshoots while ensuring equally dynamic and safe performance. measurements or the coulomb measurement. Depending on...

BATTERY CELL SIMULATOR BATTERY CELL SIMULATOR INTEGRATED FAULT SIMULATION For best results and precise cell voltage, fault simulation is integrated in the BCS electronics of every cell. Measurement errors play a key role when the state of charge of the cells in a battery pack is being determined. Even inaccuracies of ±10 mV hamper active charge balancing. Cell measurement accuracy depends on the CMC’s voltage reference. The simplified discharge curve depicted here shows how important precise cell voltage measurement is. Cable breaks in the connection between cells and BMS, material fatigue,...

BATTERY CELL SIMULATOR BATTERY CELL SIMULATOR THERMAL TEMPERATURE MONITORING MATCHING HARDWARE AND SOFTWARE Battery cells have a narrow range of working temperatures. Both the lifespan and cycle stability of a battery cell and the functional safety of a battery depend largely on the battery cell staying within this range. If the temperature exceeds a critical limit, a thermal runaway will result; the temperature increases drastically within milliseconds and the energy stored in the battery is released abruptly. Extremely high temperatures lead to a fire that is very difficult to extinguish...

BATTERY CELL SIMULATOR BATTERY CELL SIMULATOR MODELING BATTERIES The state of charge is an important parameter for all battery-operated devices and plays a major role in energy storage systems. Its value is 100% when a battery is fully charged and decreases to 0% during discharging. Voltage measurements are generally used to determine the SoC value. With this method, a fully charged battery can be recognized by its higher voltage. However, the difference in voltage between the fully charged and discharged states is often only a few volts (V). An alternative is to determine the SoC value by...

BATTERY CELL SIMULATOR INTEGRATED INTERFACE TESTING SPECIFICATION SHEET FOR BATTERY CELL SIMULATORS an alert to the charging station to interrupt the charging process and prevent damage to the vehicle battery. This means it is extremely important to test all relevant parameters between the BMS and the EVCC in the lab with an integrated test bench early in the development phase to ensure that potential sources of error are detected safely, automatically and reproducibly so that future risks can be avoided. Years of practical experience and insights from extensive electrical fault simulations...
