Abstract
In a DC impedance measurement routine for a battery the current load from a source is initially set to a low setting. The system waits for a set time in this state for the voltage readings to stabilize. Once the voltage is stable at the low current setting, the current setting is changed to a high value and the voltage is read quickly. Then the current load is set back to the low setting immediately after the reading is made. Several consecutive measurements are performed by repeating the steps above. A DC impedance measurement system that can be used to carry out the measurement routine. A multi-battery system can be monitored via a DC impedance measurement system and the routine being performed on each battery.
