New Online Detection Method of State of Charge of Car Batteries

Abstract:

By theoretical analysis and experiment, this article studied the rebound voltage of lead-acid battery when off-lined. By considering elements as discharge rate, depth of discharge, and environment temperature and so on, we experimented and found the relationship between the rebound voltage and the state of charge (SOC) of battery, which provided reliable basis to estimate the SOC of battery by rebound voltage.
