AI Customer Service“Test stand drives with accurate application parameters can reduce operating costs, testing time and mitigate safety risks” Battery Module and Pack tests typically evaluate the battery performance, safety mechanisms, cooling systems, and internal heating characteristics.
Engineers also check for any malfunction, temperature rise in the battery pack, current carrying capacity, cooling capacity, and overall mechanical structure. After complete testing, packs may undergo extra testing to simulate the typical conditions and be integrated into the system or end-product.
Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode. A method called Coulomb counting uses these measured currents to calculate the SoC and SoH of the battery pack. The magnitude of currents during charging and discharging modes could be drastically different by one or two orders of magnitude.
Therefore, in discharging mode, current flows in the opposite direction from charging mode, out of the HV+ terminal. Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode. A method called Coulomb counting uses these measured currents to calculate the SoC and SoH of the battery pack.
Battery pack voltage, using a high-voltage resistor divider. Shunt temperature, using a thermistor. Auxiliary measurements, such as the supply voltage, for diagnostic purposes. As demand for batteries to store energy continues to increase, the need for accurate battery pack current, voltage, and temperature measurements becomes even more important.
Cell balancing: The individual battery pack cells need to be monitored and balanced to redistribute charge between cells during charging and discharging cycles. Temperature monitoring: The individual cell temperatures and battery pack temperatures at several locations need measuring to ensure safe operation with maximum efficiency.
