BRIC-1 (BATTERY IMPEDANCE CLASSIFIER)
BRIC-1 (Battery Impedance Classifier) is a battery internal resistance testing equipment. It provides Four wire method to test a battery. and measure its Ohm (internal resistance), testing voltage and testing current. BRIC-1 provides two terminals for voltage and two terminals for current to test a battery.
Effects Of Internal Impedance
When current flows in the cell, an IR voltage falls in the internal resistance of the cell, which reduces the terminal voltage of the cell during discharge and increases the voltage required to charge the cell and thus its effective capacity Along with reducing its charge/discharge efficiency. Higher discharge rates give rise to higher internal voltage drops.
