A representation of the DC-Fast charger with BESS is presented in Figure 2. The idea behind using DC-fast charging with a battery energy storage system (BESS) is to supply the EV from both grid and the battery at the same time . This way the demand from the grid is smaller.
When charging at a constant voltage, the battery's voltage is maintained as the charging current gradually decreases towards zero as the battery nears full charge. By controlling the voltage between the battery terminals, this method protects the battery from being overcharged. iii.
The fine-tuning resistance method performs better and extends the battery life. The purpose of this study is to fill the research gap of direct parallel charging for batteries and supercapacitors. However, a simple parallel connection between the two will create a disproportionate current distribution and limit the effective capacity utilization.
Constant-current charging entails sending a constant current to the battery during the charging process. The charging rate remains constant as the battery voltage increases. When the battery voltage is low, this method is frequently utilized in the early stages of charging. ii.
Compared with the constant current charging (CC), the charging time is only prolonged by 6.8 min with this method, but the charging capacity is increased by 48.4%, reaching 95.1% of the rated capacity for the hybrid system.
Tanim et al. demonstrated that the CC-CV strategy can achieve over 80 % charge in 10 min with currents from 6.8C to 9C, validating its potential for fast charging. Utilizing the CC-CV charging strategy can prevent both overcharging and overdischarging of the battery, crucial factors for prolonging the battery's lifespan.
