6 FAQs about [How to control charging and discharging of energy storage]
What is battery discharging mode?
In discharging mode, the control system is supposed to limit the battery current and avoid over-discharging throughout the time that battery regulates the DC voltage by the control of energy discharge.
Which control method is best for battery charging and discharging?
While constant-current–constant-voltage (CC–CV) is the most commonly used control method for battery charging and discharging, other methods such as FLC or MPC have shown better performances.
How can charging time be reduced?
Charging time can be reduced by using fuzzy logic control or model predictive control. However, several studies show that charging time can be reduced by using fuzzy logic control or model predictive control. Development of control methods seeks battery protection and a longer life expectancy, thus the constant-current–constant-voltage method is mostly used.
How efficient is the charge control method?
The charge control method's efficiency depends on several factors, including the amount of current used for charging, the level of oscillations in the charging current, the charging voltage levels, the charging time, and temperature fluctuations during the charging process [27].
Why does the control method take a long time to charge the battery?
However, this control method requires a long time to charge the battery, which generates battery temperature rises and produces irreversible battery damage. Moreover, during the process of battery charging and discharging, traditional controls leave some aspects uncontrolled.
Can fuzzy logic control reduce charging time?
However, several studies show that charging time can be reduced by using fuzzy logic control or model predictive control. Another benefit is temperature control. This paper reviews the existing control methods used to control charging and discharging processes, focusing on their impacts on battery life.
