The current control system is commanded by a superimposed battery voltage controller aimed at bringing the battery terminal voltage to the fully-charged state while also limiting the maximum battery charging current.
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement. This method is suitable for Ni-MH type of batteries.
However, most of the current research has ignored the expansion of the battery during charging, which will increase the capacity and performance loss during charging. Therefore, a constant-current constant-strain (CC-CS) charging strategy with multiple closed-loop control is proposed in this paper.
Thus, the charging control system can easily accommodate for different battery chemistries characterized by different charging currents and final (fully charged) battery terminal voltage values. In order to facilitate effective current and voltage control during charging, different controller types have been proposed.
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Constant current/constant voltage is a combination of the above two methods. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level.
Constant Voltage Mode (CV Mode): In this mode, the charging voltage applied at the battery terminals is maintained constant regardless of the battery charging current. Let’s examine these charging modes within the context of EV charging.
