Satisfy your Battery Test Requirements such as charge rate, discharge rate, state of charge (SOC), and state of health (SOH), and depth of discharge (DoD) with accuracy in measuring voltage, current, temperature and power both statically and dynamically.
DC Impedance Measurement For Battery Cell
The battery pack for electric vehicles requires the battery cells be paralleled for large current use. An important parameter is the impedance consistency of the battery cell since battery life may be affected if the impedance is not consistent. The DC impedance test solution offered by Chroma sets the discharge current change (ΔI) and measures the voltage change (ΔV), and then calculates the battery’s internal resistance using ΔV/ΔI as shown in the figure below.
