Hazardous conditions due to low-temperature charging or operation can be mitigated in large ESS battery designs by including a sensing logic that determines the temperature of the battery and provides heat to the battery and cells until it reaches a value that would be safe for charge as recommended by the battery manufacturer.
However, models that commonly represent operation of a large-scale battery energy storage are inaccurate. A major issue is that they ignore the dependence of the charging power on the battery state of energy.
During a single charge process, as the battery gains energy, the voltage rises. This rate of increase in the voltage decreases as the battery charges up.
As concerns the fact that efficiency of the battery sharply increases when the charging current surpasses the discharge current, when the charging current increases above the discharge current, the rate of energy storage significantly increases while the discharge current remains the same.
It was then inferred from this work that the very long time required to charge batteries at lower rates is not only due to the smallness of the magnitude of the current per say but due to the fact that at such low currents, the charging process is ineffective.
Insufficient charging time can result in incomplete charging or battery damage due to excessive charging current, leading to a chemical imbalance within the battery. Conversely, an excessively long charging time may cause overcharging issues.
