To identify the battery SOH curves with high similarity under identical charge-discharge conditions, a double correlation based early-stage SOH similarity analysis method is presented.
In most cases, precise values of the state of charge can already be obtained by current estimation methods. However, by cause of the hysteresis of lithium-ion batteries, the accurate open circuit voltage value cannot be transmitted to the battery management system, resulting in a biased appraisal of the state of charge.
It is imperative to determine the State of Health (SOH) of lithium-ion batteries precisely to guarantee the secure functioning of energy storage systems including those in electric vehicles. Nevertheless, predicting the SOH of lithium-ion batteries by analyzing full charge–discharge patterns in everyday situations can be a daunting task.
The specific experimental process is shown in Figure 2. First, put the lithium battery at −20 °C, −5 °C, 10 °C, 25 °C, and 40 °C ambient temperature for 10 h, and then charge it with a constant current of 1C to the end-of-charge voltage (4.2 V), and then switch to constant-voltage charging. Stop charging when the charging current drops to 0.05C.
A reduced-order model for designing and parametrically characterizing the dynamic voltage response of lithium-ion batteries is proposed, leading to the derivation of battery SOH .
While most household lithium-ion batteries consist of a single electrochemical cell generating a cell voltage of around 3.4 V, batteries providing higher voltages can be constructed from several such electrochemical cells in series.
