The Method of Constant Current - Constant Voltage (CC – CV) for SECA Electric Car Battery Charging with Fuzzy Logic Controller

Electric cars are a solution to overcome the depletion of fossil fuels and environmental impacts.An electric car is a type of electric vehicle that uses a battery as the primary energy source.In charging, the battery is prone to overcharging, so a charging system is needed to maintain battery performance to avoid damage to the battery.In this study, researchers have tested a SECA electric car to charge the battery using a method of constant current -constant voltage (CC -CV) that applies a constant current at the initial stage and a constant voltage till the battery has charged fully.The battery type is a lead acid battery with 12V, 30Ah capacity.The analysis of this battery charging system has been proven by the fuzzy logic controller (FLC) as the current and voltage controller based on its rule base to get higher performance improving the charging system.Charging the battery with this system is expected to maintain battery lifetime by avoiding overcharging the battery during the charging process.
